Modernizing A Classic 4×4 Land Cruiser

Upgrading an Older 4×4 Vehicle While Maintaining Vintage Style

I distinctly remember complaining that I’d paid too much when I bought my 1973 classic 4×4 Land Cruiser FJ40 from a friend in 1978. True, it only had 23,000 miles on it and was in “as-new” condition. But still, couldn’t a buddy have accepted less than $3,500?

I know what you’re thinking—and you’re right: In vehicular terms, that purchase was an investment right up there with IPO Apple stock. More than 300,000 miles later, that FJ40 has yet to leave me stranded a single time, except as the result of a dead battery. It’s been used for exploration, guiding sea kayaking trips in Mexico and four-wheel-drive training (not to mention a first date with my wife). And it’s now insured for more than 10 times what I paid for it.

Legends Live Long Lives

There are other owners of early Land Cruisers, first-generation Broncos, Series Land Rovers, Jeep CJs and Scouts who were lucky to score them when they were just old 4x4s, along with an increasing number of passionate fans who were happy to shell out a lot more in recent years to fulfill their dreams of owning a legend.

“My classic 4×4 Land Cruiser was always a working vehicle; it wasn’t reserved for weekends or fishing trips, and it certainly never towed to trails. So, early on, I began to think about ways to overcome some of its daily-driver deficiencies.”

But, while our vehicles’ values have soared into the 21st century, their engineering remains firmly stuck in the mid-20th. My Land Cruiser came with four-wheel drum brakes, simple lap belts and no head restraints, a three-speed transmission with a non-synchro first gear, a points-style distributor and sealed-beam headlamps perfected in 1940. Fully adjustable air conditioning was available … via the window crank. Traction aids? None. Driving 65 mph on the freeway produced instant tinnitus. Other 4x4s of the same era share many (or all) of these traits.

Luckily for me and many other owners, the corollary to rising classic values is an increase in the number of companies offering parts and accessories to upgrade our classic vehicles.

Maintaining a Classic

In fact, Toyota recently announced it will resume manufacturing critical drivetrain and other components for early Land Cruisers. We’re in a “golden age” for those who want to keep their vintage 4×4 in crowd-gathering condition while increasing its comfort, safety and capability—yet (mandatory for me) not turning it into a Frankenstein monster with an LS crate engine and an automatic transmission.

A full front roll cage provides protection, anchoring for three-point belts, and mounting for radios, flashlight and switches.

My classic 4×4 Land Cruiser was always a working vehicle; it wasn’t reserved for weekends or fishing trips, and it certainly never towed to trails. So, early on, I began to think about ways to overcome some of its daily-driver deficiencies. Life as a wilderness guide and freelance writer, however, meant that most of those modifications came at a leisurely pace. It was only this year that was I able to dedicate a chunk of funds to tackle several major upgrades at once.

Safety First

The lack of safety features was an obvious shortcoming. Curiously, the 1973 FJ40 seats came with receptacles for head restraints but not the actual items, so I sourced a pair from a 1976 in a wrecking yard. Installing three-point harnesses proved a bit more challenging, because there were no factory mounts for those.

Head restraints and three-point seatbelts significantly enhance safety.

However, another safety modification I had planned was a roll bar (standard on later FJ40s). I bolted in a full front cage, which provided a secure mount for three-point, inertia-reel harnesses. At that point, I was much better protected from both rear and front impacts, not to mention—yikes!—a possible rollover.

Last, but not least, I installed a pair of larger and steadier Euro-spec factory Toyota door mirrors to better spot trouble coming before it arrives. (I still have no idea why Europe got better mirrors on its Land Cruisers.)

Euro-spec factory mirrors are a huge improvement on stock, U.S.-spec mirrors.

Upgrading Stopping Power

Next up were those drum brakes—also standard at the time on Broncos, Scouts, CJs and Land Rovers. Contrary to myth, drum brakes stop just fine; well, at least two or three times in a row and as long as they’re not wet. Towing a 21-foot sailboat to Mexico revealed significant fade issues, and after crossing a stream, the brakes were simply not there until frantic pumping dried them out.

Four-wheel disc brakes transform stopping power and fade resistance.

There are several ways to install front disc brakes on early FJ40s, including swapping in the entire front axle from a 1976 or later model. I chose a simple, bolt-on kit using Wilwood calipers and ventilated discs. The improvement was remarkable, so I thought that if two disc brakes were good, four could only be better. I found another kit to convert the rear to discs as well.

“Brake fade” is no longer in my FJ40’s vocabulary, although the system required an adjustable proportioning valve to prevent too-enthusiastic rear lockup. More recently, I replaced the stock brake booster with a dual-diaphragm unit from City Racer, which is a most strangely named, but excellent, supply source for classic 4×4 Land Cruisers.

Technology-Infused New Lighting

The need to still see when driving from dusk into the night is important when traveling (or otherwise). The 7-inch, sealed-beam headlamps were the next to go, replaced with excellent Cibié Z-Beam halogens. A pair of Cibié Super Oscar halogen driving lamps spectacularly augmented the headlamps for nighttime forays down the Arizona and Mexico open-range dirt roads, which are randomly crossed by cattle and deer.

Different angles of the lamps.

However, more recently, the revolution in LED lighting swayed me to make a major conversion. First, I installed a set of ARB’s superb Intensity 21 driving lamps; and, just last month, I installed a headlamp replacement, courtesy of the Gravity units from KC HiLites—a drop-in fit for any vehicle equipped with 7-inch round headlamps. The KC headlamps have none of the color-fringing or spotty pattern of earlier 7-inch LED conversions I’ve tried, and the Intensity driving lamps “bored” a huge hole of daylight down the trail when needed. (I’m also currently testing a set of ARB’s new Solis driving lamps, which are dimmable—a seemingly odd feature that is actually quite useful.)

In addition to superior illumination, the extremely low amp draw of LED lamps puts less stress on the Land Cruiser’s modest, 55-amp alternator. The KC headlamps draw fewer than four amps per pair, compared to more than 16 for the Hellas.

Keeping it Retro While Increasing Capability

In its day, the FJ40 was known as one of the most capable four-wheel-drive vehicles on the planet. But that was before the advent of compliant suspensions, locking differentials and traction-control systems. Today, a stock FJ40, on stiff factory springs and open diffs, is outclassed—at least in traction—by more than a few cute utility vehicles.

Personal style makes a vintage vehicle stand out in a crowd.

I installed an Old Man Emu Medium spring kit, which added 2 inches of ground clearance and hugely improved both compliance and comfort, complemented by OME Nitrocharger shocks. However, the real transformation came with an ARB rear locking differential, which increased available traction by a solid 50 percent and eliminated those embarrassing moments when diagonal tires spin futilely in the air at a spot a Wrangler Rubicon could just stroll through. A bonus was the ARB heavy-duty compressor activator that doubled for airing up tires.

Right Fit Rubber

Long experience with overlanding in Africa had convinced me that a 235/85R16 tire was the perfect size for my needs—but U.S. Land Cruisers only came with 15-inch wheels. For a time, I ran factory, 16-inch split rims with tubed tires, but the “romance” of those wore off quickly (because even a simple nail puncture requires a complete breakdown of the wheel).

City Racer 16×6 wheels take factory hubcaps and LT235/85R16 BFG All-Terrains.

Again, City Racer came to the rescue with Japanese-manufactured, 16×6, one-piece steel rims that take the factory hubcaps and have clearance for disc brakes. Now, my FJ40 on its BFG All-Terrains has the capability I want, as well as the perfect retro look.

Stepping up Self-Recovery

Of course, even with a locker, great suspension and good tires, there’s a chance of getting stuck—or needing to assist someone who is. In my mind, the only proper winch for an FJ40 is WARN’s mighty 8274.

“ … the real transformation came with an ARB rear locking differential, which increased available traction by a solid 50 percent … ”

The FJ40’s front end was factory configured for easy winch-mounting; I added a shorter, heavy-duty bumper and had a friend weld in a mount with a roller fairlead, exiting through the bumper to keep the winch as low as possible and not block airflow through the radiator (Man-A-Fre offers a similar unit that’s ready-made). The only change I made was to replace the steel cable with a safer and lighter Dyneema.

Additional Fuel Options

For accessing areas where I could exploit all this newfound capability, the classic 4×4 Land Cruiser’s stock fuel tank (sited under the passenger’s seat) is decently sized, at 18.5 U.S. gallons (the same-era Land Rover 88 held 12 gallons; the first-generation Bronco held 12.5)—but it was still marginal for long, no-resupply routes in Mexico.

The Stout Equipment rear rack carries a spare and two jerry cans—rattle- and vibration-free. (Look closely, and you’ll see a feature to be highlighted in part two of this feature.)

Man A Fre makes a replacement, 28-gallon saddle tank that wraps around under the driver’s seat. However, that was just a bit too much fuel to be sitting on. (As if, in a devastating accident, I’d be less toasted by an 18-gallon fireball than by a 28-gallon fireball.) A company in New Mexico called Stout Equipment (now sadly defunct) built a stout, swing-away rear rack for the spare tire, with a braced shelf that holds two NATO jerry cans. (The rack is so sturdy that, on a bet, I once jacked the entire rear end of the vehicle off the ground using the back side of the jerry can shelf.) A similar unit is available today from 4Plus Products.

More To Come for This Classic 4×4 Land Cruiser

So far, I’d significantly improved the FJ40’s safety, off-road and self-recovery capability, as well as its driving range. But, in the back of my mind were several more ambitious projects.

What if I could improve highway comfort and economy by reducing engine rpms—while, at the same time, lower the low-range gearing to enhance rock-crawling performance?

In addition, Arizona summers aren’t getting any cooler, and the windows-down-and-50-mph “AC” wasn’t cutting it.

Finally, I had a plan to enhance interior storage for my own and similar short-wheelbase classic vehicles while incorporating some convenience features for camping—an on-board water supply with tap, a bulk propane supply for cooking and, of course, a fridge. Would it all fit and leave enough room for spare socks?

I’d find out.

How does increasing wheel travel impact vehicle ride quality and control?

The Impact of Increased Wheel Travel on Ride Quality and Control

Enhancing wheel travel can significantly improve a vehicle’s ride quality and control, transforming your driving experience. When we measured the wheel travel on a modified vehicle, it clocked in at 11.4 inches compared to the stock version’s 9.05 inches. This might not seem substantial at first glance, but it translates into a 26% increase in wheel travel.

Smoother Ride Over Bumps

With this additional 2.35 inches, the suspension is able to absorb impacts more effectively. As a result, each bump you encounter feels 26% smaller, creating a smoother ride. This means less jarring from the road, making daily commutes and long journeys more comfortable.

Comparing to Other Vehicles

Consider how this increased wheel travel stacks up against popular 4x4s. For instance, the lauded wheel travel on models like the Ford Bronco sits at about 10.2 inches. With enhanced suspension, this vehicle can surpass various competitors, offering superior articulation and a more refined ride.

Systemic Advantages with Tire Size

The benefits of increased wheel travel are further amplified when combined with larger tires. Upgrading to a 33.2-inch tire from a standard 31.5-inch size increases height, which makes obstacles seem approximately 5.4% smaller. Combined with enhanced shocks, these improvements result in significantly improved ride quality and vehicle control.

In summary, increased wheel travel provides better impact absorption and ride smoothness, while larger tires and improved shock systems further enhance handling and control. These modifications create a more resilient and reliable driving experience across varied terrains.

 

What is long travel suspension, and how does it improve vehicle performance?

Understanding Long Travel Suspension

What is Long Travel Suspension?

Long travel suspension is an advanced suspension system designed to enhance the performance of vehicles, especially in off-road conditions. Unlike traditional setups, long travel systems extend the range of motion for a vehicle’s wheels, allowing for greater articulation. This is primarily achieved by using longer control arms and lengthened CV axles, which increases the path over which the wheel can travel vertically.

How Does It Work?
  1. Independent Front Suspension (IFS):
    • Most modern vehicles with four-wheel drive use IFS, where the front differential is mounted to the vehicle’s frame.
    • Rather than using a single-piece drive shaft, they utilize CV axles that allow for complex movements.
  2. Control Arms and Coilovers:
    • The wheel’s movement in an IFS setup is directed by upper and lower A-arms.
    • A coilover—a combination of shock absorber and spring—suspends the vehicle’s weight and moderates its motion.
  3. Increased Articulation:
    • Long travel setups expand the arc of movement for each wheel. This is made possible by using longer control arms and adapted CV axles.
    • Remote reservoir shocks are often employed to handle the increased travel by allowing fluid to move into a chamber external to the shock body.
Performance Benefits
  • Enhanced Ride Quality: By increasing wheel travel, the impact of any given obstacle is minimized, turning large bumps into minor disturbances. This leads to a smoother ride, even on uneven terrain.
  • Improved Control: The expanded suspension travel ensures that wheels remain in contact with the ground more consistently, providing better traction and handling.
  • Adaptability to Speed: Vehicles equipped with long travel suspension can manage high-speed travel across rough surfaces with more stability and comfort.
Limitations

While offering numerous benefits for off-road enthusiasts and desert racers, long travel suspension setups usually require more frequent maintenance. They are often designed to perform exceptionally well under specific conditions but can be less effective in day-to-day driving on smoother surfaces.

In summary, long travel suspension transforms vehicles by significantly enhancing their ability to tackle challenging terrains, leading to superior ride quality and control.

 

What are the advantages of a wider track width on a vehicle?

The Advantages of a Wider Track Width on a Vehicle

A wider track width on a vehicle brings several key benefits that enhance both driving confidence and vehicle performance.

Improved Stability
  • Offsetting Height Instability: When a vehicle’s height is increased, it can lead to a higher center of gravity, resulting in potential instability. A wider track width helps to counteract this by broadening the stance of the vehicle. This ensures that any instability caused by additional height is effectively managed.
Enhanced Off-Road Experience
  • Superior Off-Road Handling: In off-road scenarios where uneven terrain may cause the vehicle to lean excessively, the expanded track width provides a more stable base. This diminishes the feeling of imbalance, allowing the vehicle to navigate challenging landscapes with greater assurance.
Better On-Road Performance
  • Increased On-Road Control: On paved roads, the wider track width reinstates any stability that might be compromised due to a raised center of gravity. This translates to smoother handling and a more confident drive, whether you’re on a highway or taking sharp turns.
Overall Confidence Boost
  • Enhanced Grip and Ride Quality: The broader track enhances grip, allowing for more precise control and a smoother ride. This translates into an overall boost in driver confidence, knowing that their vehicle can handle diverse conditions with ease.

In summary, the wider track width not only stabilizes vehicles with higher profiles but also elevates their performance across various terrains and driving conditions.

 

How does independent front suspension (IFS) differ from solid axles, and what are its benefits?

Understanding the Differences: Independent Front Suspension vs. Solid Axles

Solid Axles:
In the past, trucks relied heavily on solid axles both at the front and rear. This design is straightforward and robust, providing significant wheel articulation—ideal for rock crawling and other rugged terrains. However, the downside is that solid axles can negatively affect a vehicle’s ride and handling on smoother surfaces, making daily driving less enjoyable.

Independent Front Suspension (IFS):
Conversely, modern vehicles often incorporate Independent Front Suspension (IFS), particularly in four-wheel-drive trucks. Unlike solid axles, IFS mounts the front differential to the frame, utilizing CV (constant velocity) axles that flex and rotate, allowing for smoother performance on paved roads. This results in better handling and a more comfortable ride as the wheels move independently.

Benefits of Independent Front Suspension
  1. Enhanced Ride Comfort:
    IFS systems use upper and lower A-arms to control wheel movement, paired with a coilover shock and spring setup. This allows for a smoother ride by isolating each wheel’s movement, improving comfort and reducing vibrations felt within the cabin.
  2. Improved Handling:
    Since the wheels operate independently, IFS offers superior handling characteristics, particularly on uneven or paved surfaces. This independence from the terrain allows for better traction and responsiveness.
  3. Increased Versatility:
    Initially limited by factors like cost and safety, stock IFS systems found in desert racing have been modified to introduce more flexibility and articulation. By lengthening the control arms and extending the track width, racers achieved what’s known as “long travel” suspension. This not only improves off-road capability but also enhances the vehicle’s performance at high speeds on rough surfaces.
  4. Reduced Impact of Obstacles:
    With the addition of longer CV axles and remote reservoir shocks in long-travel IFS systems, the amount of wheel travel is increased. This diminishes the impact of terrain irregularities, allowing the vehicle to glide over larger bumps with greater ease, translating to a smoother and more controlled ride.

In summary, Independent Front Suspension provides a balanced solution, improving both comfort and capability for those venturing off the beaten path while maintaining excellent drivability for everyday use.

 

How did desert racing influence the development of long travel suspension systems?

How Desert Racing Shaped Long Travel Suspension Systems

Decades ago, trucks were built with solid front and rear axles. This design was robust and allowed for significant wheel movement, which was advantageous in off-road conditions. However, solid axles did not provide the best ride quality or handling when off the rocks and onto regular terrain.

The Shift to Independent Front Suspension (IFS)

To improve on-road performance, manufacturers introduced independent front suspension (IFS) in four-wheel drive vehicles. This setup involves mounting the front differential to the frame and using complex CV axles that facilitate flexibility during operation. IFS controls wheel movement with upper and lower A-arms, along with coilover shocks and springs that support and dampen the vehicle’s weight.

The Desert Racing Revolution

Enter desert racing, where speed across rugged landscapes takes priority. Racers quickly discovered that the same qualities that made IFS excellent for comfort and control could be amplified for high-speed travel over rough terrain. The key was increasing wheel articulation without compromising suspension integrity.

Creating Long Travel Suspensions

By lengthening the upper and lower control arms in the suspension, racers extended the wheel’s range of motion. Longer CV axles accommodated this increased track width, and pairing them with advanced remote reservoir shocks allowed for greater shock travel. These remote reservoirs provided additional fluid space, ensuring smoother operation over larger distances.

Impact on Ride Quality and Control

The result of these innovations was a significant improvement in how vehicles handled bumps and jolts. Increased wheel travel meant that even large bumps felt smaller, enhancing both ride comfort and driver control at high speeds—a crucial advantage in the demanding environment of desert racing.

In summary, the demands and innovations from the world of desert racing spurred the development of long travel suspension systems, transforming vehicle performance on and off the track.

The balance between aesthetic appeal, practicality, and performance is continuously redefined, creating a diverse market that caters to a wide spectrum of consumer needs.

 

What environmental considerations should be taken into account with large, modified trucks?

Environmental Considerations for Large, Modified Trucks

When discussing the environmental impact of large, modified trucks, it’s crucial to consider several key factors. One significant concern is fuel consumption. Large trucks are often equipped with powerful engines and additional modifications that add weight, resulting in reduced fuel efficiency. For instance, a hefty truck may deliver around 14 miles per gallon, which is notably inefficient compared to more economical vehicles.

Fuel Economy Impacts

The Environmental Protection Agency (EPA) provides fuel economy estimates for vehicles, but these are often based on controlled conditions that might not reflect real-world driving. Factors such as elevation changes, off-road terrains, and high-speed driving can further decrease fuel efficiency. In rugged conditions, even slight modifications can lead to an average of around 13 miles per gallon, highlighting the strain on fuel resources and increased emissions.

Carbon Emissions

The carbon footprint of a large truck can be significant. Driving approximately 10,000 miles a year in such a vehicle could result in about six metric tons of carbon emissions. While this seems substantial, comparisons with other modes of transportation, such as air travel, reveal a complex picture. A round-trip flight can sometimes exceed the annual emissions of a single vehicle, showing that transportation choices are complex and nuanced.

Consumption Cycle and Broader Impacts

Examining one’s carbon footprint involves looking beyond just vehicle emissions. Each individual’s total consumption cycle is intricate and typically larger than it initially appears. For example, lifestyle choices, such as family planning, can have a profound impact. A decision to forego having children can save an estimated 58 tons of carbon emissions per year per child.

Contextual Use and Justifications

If extreme capability and performance are necessities, large trucks may justify their environmental footprint, provided they are irreplaceable for specific tasks. However, for general purposes, more efficient vehicles should be considered.

Societal Solutions

Addressing the environmental impact of individual vehicle use requires a societal shift. Community and policy-driven solutions can lead to significant reductions in emissions. By focusing on larger-scale approaches, we can move beyond merely critiquing personal choices and work towards collective strategies for environmental preservation.

Ultimately, while large modified trucks offer unique capabilities, their environmental considerations are multi-faceted and require careful examination and thoughtful action to mitigate their impact.

 

What are the unique features of the Land Cruiser that make it suitable for modifications?

Unique Features of the Land Cruiser for Modifications

The Land Cruiser stands out for its versatility, making it an ideal choice for customization. One of its most distinct features is the Kinetic Dynamic Suspension System (KDSS). This innovative system automatically disconnects the front and rear sway bars when navigating tough off-road terrain. On paved roads, sway bars help control body roll by applying pressure to the outer suspension during turns. However, off-road, these bars can limit wheel movement and reduce traction because they restrict wheel articulation.

The KDSS addresses this issue by allowing maximum wheel articulation without manual control. It uses oil pressure in dedicated lines between each axle to sense and respond to force differences, seamlessly connecting or disconnecting the sway bars. This system functions independently of the vehicle’s shocks, springs, and axles, making it compatible with both stock and aftermarket suspensions effortlessly.

Another aspect that enhances the Land Cruiser’s modifiability is its parts commonality with other vehicles within the brand’s truck line. Many components, such as bushings and bolts, share sizes and specifications across different models. This standardization, while primarily cost-saving for the manufacturer, provides owners with a Lego-like flexibility to interchange parts. This opens up a broad range of customization possibilities, allowing enthusiasts to easily adapt and modify their vehicles.

 

What is the significance of parts commonality in Toyota’s truck range for modifications?

Understanding Parts Commonality in Toyota’s Trucks for Modifications

Parts commonality within a vehicle range offers significant advantages, especially for those interested in modifications. In Toyota’s trucks, this concept is particularly beneficial. The consistent use of components, such as bushings, bearings, and bolts, across various models simplifies the modification process, as these interchangeable parts make it easier to customize and enhance a vehicle to suit personal preferences.

This approach primarily originates from manufacturing efficiencies, allowing companies to reduce costs while improving resource allocation. However, for enthusiasts, it provides an unexpected boon: the flexibility to creatively enhance their vehicles. Much like assembling a Lego set, owners can mix and match parts to explore unique configurations and build options that would otherwise require extensive, costly adaptations.

In essence, the standardization within Toyota’s truck lineup unlocks a realm of intriguing possibilities for those eager to explore customization without the constraints of high expenses or scarce parts.

 

How does the Kinetic Dynamic Suspension System (KDSS) enhance off-road performance?

The Kinetic Dynamic Suspension System (KDSS) takes off-road capability to the next level by intelligently managing the vehicle’s sway bars.

Enhanced Traction and Stability
  • Automatic Sway Bar Disconnection: KDSS can automatically disconnect the front and rear sway bars when you encounter challenging off-road conditions. This allows for greater wheel articulation, enhancing traction. Without this feature, traditional sway bars might limit your vehicle’s ability to maintain contact with uneven terrain, reducing traction.
  • Smooth Performance on Various Terrains: On regular roads, sway bars stabilize the vehicle by applying downward pressure on the outside suspension while cornering, preventing excessive body roll. KDSS toggles between this road stability and off-road flexibility seamlessly.
Innovative and Hassle-Free Design
  • Hydraulic Pressure System: The KDSS utilizes hydraulic pressure through dedicated lines to sense pressure differences between axles. This unique approach avoids complicated electronics and allows it to function without driver input, making it a robust and reliable feature even when upgraded suspension systems are in place.
  • Compatibility with Aftermarket Parts: Because KDSS operates independently of the vehicle’s shocks, springs, and axles, it maintains its effectiveness regardless of whether you’re using stock or aftermarket suspension components. This ensures maximum versatility for off-road enthusiasts seeking customized setups.

In summary, the KDSS enhances off-road performance by providing automatic adaptability to varying terrains, maintaining vehicle stability, and offering flexibility with different suspension configurations.

 

How does the Kinetic Dynamic Suspension System contribute to vehicle stability?

KDSS is adept at managing the transition between different driving conditions. On rough dirt roads, it deftly disconnects and reconnects components as needed. This adaptability keeps the vehicle level not only on uneven ground but also during high-speed corners. Such agility is rare, with few systems providing comparable stability.

Overall, KDSS works behind the scenes to deliver a balanced and controlled driving experience, ensuring the vehicle remains stable whether on the pavement or exploring rugged landscapes.

 

What is the broader impact of individual carbon footprints compared to other consumption cycles?

Understanding the Broader Impact of Individual Carbon Footprints

When evaluating the broader impact of our personal carbon footprints, it’s crucial to consider the entire lifecycle of our consumption. A single flight might surpass the yearly emissions of a typical SUV, yet that comparison merely scratches the surface. Each of us participates in a vast and intricate web of consumption that extends far beyond our immediate actions.

The Complexity of Consumption

Our day-to-day choices, whether they’re related to transportation, housing, or food, all contribute to our overall carbon footprint. It’s easy to focus on isolated choices, such as driving a fuel-efficient vehicle, but the total impact is often much larger and interconnected. For instance, opting out of having a child can reduce an individual’s potential carbon footprint significantly—by approximately 58 tons per year.

Prioritizing Collective Solutions

Rather than fixating solely on personal decisions, it’s imperative to shift our focus toward societal solutions. Large-scale changes, such as advancing renewable energy, implementing robust public transportation systems, and crafting policies that promote sustainable living, can drive substantial reductions in carbon emissions. These collective efforts can create more impactful and lasting results than focusing solely on individual accountability.

Taking a Balanced Approach

While it’s important to make informed personal decisions—driving a vehicle that matches your needs rather than one with excessive capabilities—these actions should be balanced with a push for broader change. Encouraging societal transformation can ease the burden on individuals and fosters a more sustainable future for everyone.

By recognizing the complexity of our consumption and pushing for both individual responsibility and collective action, we can work towards a more environmentally conscious society.

 

What considerations go into choosing the right tires and wheels for off-road vehicles?

Long experience with overlanding in Africa had convinced me that a 235/85R16 tire was the perfect size for my needs—but U.S. Land Cruisers only came with 15-inch wheels. For a time, I ran factory, 16-inch split rims with tubed tires, but the “romance” of those wore off quickly (because even a simple nail puncture requires a complete breakdown of the wheel).

City Racer 16×6 wheels take factory hubcaps and LT235/85R16 BFG All-Terrains.

Again, City Racer came to the rescue with Japanese-manufactured, 16×6, one-piece steel rims that take the factory hubcaps and have clearance for disc brakes. Now, my FJ40 on its BFG All-Terrains has the capability I want, as well as the perfect retro look.

When selecting the right tires and wheels for off-road vehicles, several key considerations come into play:

  1. Size and Compatibility: The choice of 235/85R16 tires was based on their ideal fit for overlanding, offering a balance between traction and maneuverability. The right size ensures compatibility with the vehicle’s existing components, avoiding the need for extensive modifications.
  2. Durability and Practicality: While split rims with tubed tires initially seemed appealing, their practicality waned due to the complexity of repairs. Opting for one-piece steel rims not only enhances durability but also simplifies maintenance, crucial for remote terrains where help is scarce.
  3. Performance Enhancement: The switch to City Racer rims improved performance by accommodating disc brakes, a vital upgrade for better stopping power in rugged environments. This change underscores the importance of selecting wheels that support performance upgrades without compromising on safety.
  4. Aesthetic Appeal and Functionality: The new setup not only meets functional needs but also maintains a classic look, marrying form and function seamlessly. This highlights the significance of considering both aesthetics and performance in the decision-making process.

By weaving together practical needs, performance considerations, and aesthetic preferences, the choice of tires and wheels transforms the vehicle into a reliable and stylish companion for any off-road adventure.

 

How do modifications impact the vehicle’s stance and appearance?

Modifications such as a new suspension setup can significantly alter the vehicle’s height and stance, giving it a more commanding and purposeful look. While enhancing performance, these changes can also improve the visual appeal by making the wheels fit flush with the body, though they might necessitate additional modifications like bumpers for optimal functionality.

 

What are the practical considerations for temporary or seasonal tire choices?

Temporary or seasonal tires, like the 265/70R18 Falken Wildpeak A/T3W, are ideal for maintaining ride quality without modifications. They offer enhanced off-road traction and fit seamlessly on a stock vehicle, making them a practical choice during seasonal changes when specific tire performance is required.

 

How does wheel offset impact tire placement and vehicle performance?

Wheel offset is crucial as it determines the position of the tire relative to the hub. A +56 offset, typical for stock Toyota wheels, positions the tires farther inboard than aftermarket options. This offset is essential for ensuring proper tire fitment and avoiding clearance issues, which can impact both performance and safety.

 

What is the role of suspension components in tire and wheel selection?

Choosing suspension components like Tundra lower control arms and CV joints can optimize parts availability and reduce costs. These components also enhance reliability by allowing the CV joints to function at less extreme angles, which decreases the likelihood of failure while improving suspension performance.

 

How do tire dimensions affect vehicle dynamics?

Smaller tire dimensions, such as those measuring 33.2 inches tall and 10.8 inches wide, help in keeping the unsprung weight low, which can enhance the handling and efficiency of the vehicle. Additionally, tires that fit flush with the body contribute to a subtle and cohesive look, balancing performance with aesthetics.

 

How do different tire and wheel setups affect vehicle performance and aesthetics?

Long experience with overlanding in Africa had convinced me that a 235/85R16 tire was the perfect size for my needs—but U.S. Land Cruisers only came with 15-inch wheels. For a time, I ran factory, 16-inch split rims with tubed tires, but the “romance” of those wore off quickly (because even a simple nail puncture requires a complete breakdown of the wheel).

Beyond aesthetics, the choice of tires and wheels is critical for optimizing vehicle performance. Larger tires, like the 235/85R16, can significantly enhance traction and stability on rugged terrains, making them ideal for off-road adventures. The increased sidewall height provides better shock absorption, allowing the vehicle to glide over obstacles that would otherwise jolt a standard setup.

When considering wheel options, the offset plays a crucial role. It determines how the tire aligns with the vehicle’s body, affecting both handling and appearance. The City Racer wheels, with their precise fit, ensure that the tires sit perfectly within the wheel wells, maintaining a balanced stance that complements the Land Cruiser’s rugged charm.

In terms of performance, these wheels paired with the BFG All-Terrains transform the driving experience. The tires’ aggressive tread pattern grips surfaces confidently, providing a smoother ride on uneven trails and reducing the vehicle’s tendency to slip in challenging conditions. This combination of form and function ensures that the Land Cruiser not only looks the part but also performs impeccably in the field.

While aesthetics draw attention, it’s the enhanced capability that truly sets this setup apart, offering a seamless blend of vintage style and modern performance for any overlanding enthusiast.

 

How do specific tire brands and models contribute to vehicle performance?**

Certain tire brands and models are designed to enhance specific aspects of a vehicle’s performance. They can provide superior traction and durability, especially in off-road conditions, allowing the vehicle to navigate tough terrains with greater ease and confidence.

 

What are the visual and practical effects of fitting specific tires and wheels on a vehicle?**

Properly sized and positioned wheels can dramatically improve the vehicle’s stance, giving it a more assertive appearance. Practically, they ensure the vehicle remains balanced and capable of handling different terrains without compromising ride quality or requiring extensive modifications.

 

How do different wheel and tire setups influence off-road capability?**

The right combination of wheels and tires can significantly boost off-road performance by ensuring that the tires maintain contact with uneven terrain. Enhanced articulation from the suspension system allows the vehicle to tackle obstacles with ease, making challenging trails feel more manageable.

 

What is the role of wheel offset in vehicle aesthetics and performance?**

Wheel offset determines how far the wheel and tire sit in relation to the vehicle’s body. A zero offset offers a wider stance, which is often aesthetically pleasing but can also affect handling. The specific offset used can ensure the wheels fit flush with the body, providing a clean look and maintaining necessary clearance for suspension components.

 

How does tire size affect vehicle performance?**

Tire size plays a crucial role in managing unsprung weight, which can enhance the smoothness of a ride, especially on rough surfaces. A more compact tire can prevent excessive suspension movement, ensuring a stable driving experience. Additionally, while a larger tire might not always be feasible due to size constraints, it can still offer improved traction.

 

How does the fuel economy of a modified SUV compare to stock vehicles in real-world conditions?

So far, I’d significantly improved the FJ40’s safety, off-road, and self-recovery capability, as well as its driving range. But, in the back of my mind were several more ambitious projects.

What if I could improve highway comfort and economy by reducing engine rpms—while, at the same time, lowerthe low-range gearing to enhance rock-crawling performance?

Considering these enhancements, it’s crucial to acknowledge how vehicle modifications can impact fuel economy. Manufacturers often showcase fuel economy numbers derived under controlled conditions, which serve as a baseline for comparing vehicle efficiency.

However, the real world is a different beast. Factors like high elevations, steep mountain passes, and rough terrains can greatly affect fuel efficiency. In our experience, with a mix of highway and off-road conditions, the FJ40 managed an average of 13 miles per gallon. This figure reflects a balance between the added modifications and the vehicle’s inherent capabilities.

Interestingly, even with additional weight and height from modifications, the fuel economy hasn’t suffered. This suggests that the FJ40’s engine and gear setup are well-suited to handle these changes without compromising efficiency. Other vehicles might claim better fuel economy in their stock form, but they’d likely struggle to maintain such efficiency under similar modifications and conditions.

These insights underscore the importance of thoughtful modifications that enhance performance while maintaining a sensible balance with fuel economy—ensuring the FJ40 remains a reliable companion both on and off the road.

 

How does the modified SUV’s fuel economy compare to other vehicles with similar modifications?

Other trucks, even if they advertise better stock fuel economy, may struggle to match this SUV’s efficiency when subjected to similar modifications and driving conditions.

 

How do modifications impact the vehicle’s fuel economy?

Despite the modifications, the vehicle’s fuel economy remains stable, as the additional weight and height do not noticeably affect its efficiency.

 

What is the actual fuel economy achieved by the modified SUV in real-world conditions?

In practical driving scenarios, the modified SUV achieves approximately 13 miles per gallon.

 

How do real-world factors affect fuel economy?

Real-world driving conditions, such as high elevations, steep inclines, dirt roads, and high speeds, can significantly reduce a vehicle’s fuel efficiency compared to the controlled test figures.

 

What are the typical conditions under which fuel economy is tested by automakers?

Automakers determine fuel-economy numbers in controlled environments primarily to allow consumers to compare different vehicles’ efficiency accurately.

 

Why is it important to have protective features like steel bumpers and driving lights on an off-road vehicle?

However, another safety modification I had planned was a roll bar (standard on later FJ40s). I bolted in a full front cage, which provided a secure mount for three-point, inertia-reel harnesses. At that point, I was much better protected from both rear and front impacts, not to mention—yikes!—a possible rollover.

Living in an area rich with wildlife is an adventure, but it also demands extra precautions for those of us who love exploring off-road. The potential for encountering animals like deer or moose on the trails makes it crucial to prepare our vehicles with protective features.

Steel Bumpers: These are not just about adding a rugged look. They provide essential protection against animal strikes, allowing the vehicle to withstand impacts without compromising the safety systems like airbags and crumple zones. In off-road scenarios, they also shield your vehicle from scrapes and enhance your approach and departure angles, making those challenging trails a bit less daunting.

Driving Lights: Visibility is key, especially when navigating at dawn or dusk. Powerful driving lights help spot animals and obstacles early, giving you more time to react and avoid potential accidents.

Integrating these features ensures that while I’m safeguarded inside the vehicle, the exterior is equally prepared to handle the unexpected challenges of off-road adventures. Together with the roll bar and harnesses, these modifications transform the vehicle into a fortress on wheels, ready for whatever the wilderness throws our way.

 

What challenges can arise when modifying a vehicle with aftermarket parts?

“My classic 4×4 Land Cruiser was always a working vehicle; it wasn’t reserved for weekends or fishing trips, and it certainly never towed to trails. So, early on, I began to think about ways to overcome some of its daily-driver deficiencies. Life as a wilderness guide and freelance writer, however, meant that most of those modifications came at a leisurely pace. It was only this year that was I able to dedicate a chunk of funds to tackle several major upgrades at once.

One of the first challenges I encountered was deciding which aftermarket parts would best suit my needs while ensuring compatibility with the vehicle’s existing systems. The decision to incorporate an advanced suspension system was crucial. After much deliberation, I settled on a setup that offered exceptional ride quality and durability, vital for both rugged trails and daily commutes.

Challenges Faced:
  • Compatibility Concerns: Integrating aftermarket components such as upper control arms and advanced coilovers required careful planning to avoid any mismatch with stock parts.
  • Performance and Maintenance: The chosen suspension system promised extended service intervals and superior performance, but it also demanded occasional rebuilding, a trade-off I was willing to make for the smooth ride it offered.
  • Installation Complexity: Implementing these upgrades involved navigating the technical specifications, ensuring every part from shocks to springs aligned perfectly with the desired performance profile.

These modifications were not just about enhancing capability but also about crafting a ride that balanced work and adventure seamlessly. The journey of upgrading my Land Cruiser taught me that while challenges abound, the payoff is a vehicle that truly meets the demands of both wilderness and daily life.”

 

What makes the Toyota Land Cruiser an exemplary sport-utility vehicle?

Modernizing A Classic 4×4 Land Cruiser

Upgrading an Older 4×4 Vehicle While Maintaining Vintage Style

I distinctly remember complaining that I’d paid too much when I bought my 1973 classic 4×4 Land Cruiser FJ40 from a friend in 1978. True, it only had 23,000 miles on it and was in “as-new” condition. But still, couldn’t a buddy have accepted less than $3,500?

I know what you’re thinking—and you’re right: In vehicular terms, that purchase was an investment right up there with IPO Apple stock. More than 300,000 miles later, that FJ40 has yet to leave me stranded a single time, except as the result of a dead battery. It’s been used for exploration, guiding sea kayaking trips in Mexico, and four-wheel-drive training (not to mention a first date with my wife). And it’s now insured for more than 10 times what I paid for it.

Legends Live Long Lives

There are other owners of early Land Cruisers, first-generation Broncos, Series Land Rovers, Jeep CJs, and Scouts who were lucky to score them when they were just old 4x4s, along with an increasing number of passionate fans who were happy to shell out a lot more in recent years to fulfill their dreams of owning a legend.

The Land Cruiser’s reputation as an exemplary sport-utility vehicle is well-earned, combining the rugged off-road prowess typical of a Jeep with the refined comfort expected from a luxury vehicle like a Range Rover. This unique blend of attributes ensures that the Land Cruiser remains a favorite among adventurers and families alike. It offers the durability necessary for long-term use and the modern conveniences that enhance everyday driving experiences.

“My classic 4×4 Land Cruiser was always a working vehicle; it wasn’t reserved for weekends or fishing trips, and it certainly never towed to trails. So, early on, I began to think about ways to overcome some of its daily-driver deficiencies.”

But, while our vehicles’ values have soared into the 21st century, their engineering remains firmly stuck in the mid-20th. My Land Cruiser came with four-wheel drum brakes, simple lap belts and no head restraints, a three-speed transmission with a non-synchro first gear, a points-style distributor and sealed-beam headlamps perfected in 1940. Fully adjustable air conditioning was available… via the window crank. Traction aids? None. Driving 65 mph on the freeway produced instant tinnitus. Other 4x4s of the same era share many (or all) of these traits.

Luckily for me and many other owners, the corollary to rising classic values is an increase in the number of companies offering parts and accessories to upgrade our classic vehicles.

Maintaining a Classic

In fact, Toyota recently announced it will resume manufacturing critical drivetrain and other components for early Land Cruisers. We’re in a “golden age” for those who want to keep their vintage 4×4 in crowd-gathering condition while increasing its comfort, safety, and capability—yet (mandatory for me) not turning it into a Frankenstein monster with an LS crate engine and an automatic transmission.

A full front roll cage provides protection, anchoring for three-point belts, and mounting for radios, flashlight, and switches.

My classic 4×4 Land Cruiser was always a working vehicle; it wasn’t reserved for weekends or fishing trips, and it certainly never towed to trails. So, early on, I began to think about ways to overcome some of its daily-driver deficiencies. Life as a wilderness guide and freelance writer, however, meant that most of those modifications came at a leisurely pace. It was only this year that I was able to dedicate a chunk of funds to tackle several major upgrades at once.

Safety First

The lack of safety features was an obvious shortcoming. Curiously, the 1973 FJ40 seats came with receptacles for head restraints but not the actual items, so I sourced a pair from a 1976 in a wrecking yard. Installing three-point harnesses proved a bit more challenging, because there were no factory mounts for those.

  • Head restraints and three-point seatbelts: Significantly enhance safety.

However, another safety modification I had planned was a roll bar (standard on later FJ40s). I bolted in a full front cage, which provided a secure mount for three-point, inertia-reel harnesses. At that point, I was much better protected from both rear and front impacts, not to mention—yikes!—a possible rollover.

Last, but not least, I installed a pair of larger and steadier Euro-spec factory Toyota door mirrors to better spot trouble coming before it arrives. (I still have no idea why Europe got better mirrors on its Land Cruisers.)

  • Euro-spec factory mirrors: Huge improvement on stock, U.S.-spec mirrors.
Upgrading Stopping Power

Next up were those drum brakes—also standard at the time on Broncos, Scouts, CJs, and Land Rovers. Contrary to myth, drum brakes stop just fine; well, at least two or three times in a row and as long as they’re not wet. Towing a 21-foot sailboat to Mexico revealed significant fade issues, and after crossing a stream, the brakes were simply not there until frantic pumping dried them out.

  • Four-wheel disc brakes: Transform stopping power and fade resistance.

There are several ways to install front disc brakes on early FJ40s, including swapping in the entire front axle from a 1976 or later model. I chose a simple, bolt-on kit using Wilwood calipers and ventilated discs. The improvement was remarkable, so I thought that if two disc brakes were good, four could only be better. I found another kit to convert the rear to discs as well.

“Brake fade” is no longer in my FJ40’s vocabulary, although the system required an adjustable proportioning valve to prevent too-enthusiastic rear lockup. More recently, I replaced the stock brake booster with a dual-diaphragm unit from City Racer, which is a most strangely named, but excellent, supply source for classic 4×4 Land Cruisers.

Technology-Infused New Lighting

The need to still see when driving from dusk into the night is important when traveling (or otherwise). The 7-inch, sealed-beam headlamps were the next to go, replaced with excellent Cibié Z-Beam halogens. A pair of Cibié Super Oscar halogen driving lamps spectacularly augmented the headlamps for nighttime forays down the Arizona and Mexico open-range dirt roads, which are randomly crossed by cattle and deer.

However, more recently, the revolution in LED lighting swayed me to make a major conversion. First, I installed a set of ARB’s superb Intensity 21 driving lamps; and, just last month, I installed a headlamp replacement, courtesy of the Gravity units from KC HiLites—a drop-in fit for any vehicle equipped with 7-inch round headlamps. The KC headlamps have none of the color-fringing or spotty pattern of earlier 7-inch LED conversions I’ve tried, and the Intensity driving lamps “bored” a huge hole of daylight down the trail when needed. (I’m also currently testing a set of ARB’s new Solis driving lamps, which are dimmable—a seemingly odd feature that is actually quite useful.)

  • LED lamps: Offer significantly better illumination, with lower amp draw than traditional options.

In addition to superior illumination, the extremely low amp draw of LED lamps puts less stress on the Land Cruiser’s modest, 55-amp alternator. The KC headlamps draw fewer than four amps per pair, compared to more than 16 for the Hellas.

Keeping it Retro While Increasing Capability

In its day, the FJ40 was known as one of the most capable four-wheel-drive vehicles on the planet. But that was before the advent of compliant suspensions, locking differentials, and traction-control systems. Today, a stock FJ40, on stiff factory springs and open diffs, is outclassed—at least in traction—by more than a few cute utility vehicles.

Personal style makes a vintage vehicle stand out in a crowd.

I installed an Old Man Emu Medium spring kit, which added 2 inches of ground clearance and hugely improved both compliance and comfort, complemented by OME Nitrocharger shocks. However, the real transformation came with an ARB rear locking differential, which increased available traction by a solid 50 percent and eliminated those embarrassing moments when diagonal tires spin futilely in the air at a spot a Wrangler Rubicon could just stroll through. A bonus was the ARB heavy-duty compressor activator that doubled for airing up tires.

Right Fit Rubber

Long experience with overlanding in Africa had convinced me that a 235/85R16 tire was the perfect size for my needs—but U.S. Land Cruisers only came with 15-inch wheels. For a time, I ran factory, 16-inch split rims with tubed tires, but the “romance” of those wore off quickly (because even a simple nail puncture requires a complete breakdown of the wheel).

  • City Racer 16×6 wheels: Take factory hubcaps and LT235/85R16 BFG All-Terrains.

Again, City Racer came to the rescue with Japanese-manufactured, 16×6, one-piece steel rims that take the factory hubcaps and have clearance for disc brakes. Now, my FJ40 on its BFG All-Terrains has the capability I want, as well as the perfect retro look.

Stepping up Self-Recovery

Of course, even with a locker, great suspension, and good tires, there’s a chance of getting stuck—or needing to assist someone who is. In my mind, the only proper winch for an FJ40 is WARN’s mighty 8274.

“ … the real transformation came with an ARB rear locking differential, which increased available traction by a solid 50 percent … ”

The FJ40’s front end was factory configured for easy winch-mounting; I added a shorter, heavy-duty bumper and had a friend weld in a mount with a roller fairlead, exiting through the bumper to keep the winch as low as possible and not block airflow through the radiator (Man-A-Fre offers a similar unit that’s ready-made). The only change I made was to replace the steel cable with a safer and lighter Dyneema.

Additional Fuel Options

For accessing areas where I could exploit all this newfound capability, the classic 4×4 Land Cruiser’s stock fuel tank (sited under the passenger’s seat) is decently sized, at 18.5 U.S. Gallons (the same-era Land Rover 88 held 12 gallons; the first-generation Bronco held 12.5)—but it was still marginal for long, no-resupply routes in Mexico.

  • Stout Equipment rear rack: Carries a spare and two jerry cans—rattle- and vibration-free.

Man A Fre makes a replacement, 28-gallon saddle tank that wraps around under the driver’s seat. However, that was just a bit too much fuel to be sitting on. (As if, in a devastating accident, I’d be less toasted by an 18-gallon fireball than by a 28-gallon fireball.) A company in New Mexico called Stout Equipment (now sadly defunct) built a stout, swing-away rear rack for the spare tire, with a braced shelf that holds two NATO jerry cans. (The rack is so sturdy that, on a bet, I once jacked the entire rear end of the vehicle off the ground using the back side of the jerry can shelf.) A similar unit is available today from 4Plus Products.

More To Come for This Classic 4×4 Land Cruiser

So far, I’d significantly improved the FJ40’s safety, off-road and self-recovery capability, as well as its driving range. But, in the back of my mind were several more ambitious projects.

What if I could improve highway comfort and economy by reducing engine rpms—while, at the same time, lowerthe low-range gearing to enhance rock-crawling performance?

In addition, Arizona summers aren’t getting any cooler, and the windows-down-and-50-mph “AC” wasn’t cutting it.

Finally, I had a plan to enhance interior storage for my own and similar short-wheelbase classic vehicles while incorporating some convenience features for camping—an on-board water supply with tap, a bulk propane supply for cooking and, of course, a fridge. Would it all fit and leave enough room for spare socks?

I’d find out.
