The Liberator Was The First Military Motorcycle

As the world continued to plunge into chaos, it was clear by the late Nineteen Thirties {that a} second world struggle was on the horizon. In response, Harley-Davidson started the event of motorcycles designed strictly for military use, famously often known as the WLA. “W” for the sports activities household of bikes, “L” for being high-compression, and “A” clearly stands for military. At first, the U.S. Army used the 1937 WL Model instead of the RL Model that was getting used on the time. But it wasn’t till 1939 that the bike was changed by the WLA. While solely a handful of WLAs have been outfitted with a Thompson machine gun scabbard, they have been seldom utilized in battle.

The Harley-Davidson Liberator Employed A forty five-inch Flathead V-Twin Engine

For a motorbike designed to deal with the rugged and chaotic nature of the battlefield, it solely made sense the Liberator was powered by the reliable Flathead V-Twin engine. This high-compression engine effectively ran on 74-octane fuel–a low-quality possibility accessible throughout. With provides at all times essential throughout the struggle, having bikes that would run on low-cost gas was important. Thanks to its well-rounded DNA, this bike fulfilled its duties starting from escorts, mail couriers, transportation, army police, and radio work.

Because the WLA Liberator was an adaptation based mostly on the civilian WL mannequin, Harley-Davidson made some modifications to make it higher fitted to service. That included a skid/bash plate beneath the Flathead V-Twin engine for cover, saddle luggage, baggage rack, leg shields, crash bars, blackout lights, and wider fenders to assist shake off the mud. Also current have been 2.5-inch longer forks, an ammunition field, an oil tub air cleaner, and an Army inexperienced or black paint job.

With these bikes being utilized by Allied forces beneath a Lend-Lease program (in Britain, Australia, New Zealand, and the Soviet Union), it’s believed Harley-Davidson produced roughly 100,000 WLAs all through WW2. The USSR alone acquired over 30,000 models. But when the Japanese attacked Pearl Harbor in 1941, H-D had cranked up manufacturing of a extra rugged model of the WLA Liberator for use by the U.S. army. While the WLA remained the most well-liked army bike, the corporate had additionally experimented with some different variations of the bike, together with the XA which featured a BMW-sourced flat-twin boxer engine, in addition to the very uncommon TA Knucklehead.

The Harley-Davidson WLA Liberator remained in manufacturing from 1940 to 1952, taking part in a serious position in each World War 2 and the Korean War, after which later as privately-owned civilian fashions. With struggle lastly over and everybody returning house, a major majority of WLA Liberators used as service bikes have been bought to the general public. Many troopers who rode the Liberator had an affinity for the wartime bike, so quite a few WLAs made their manner again into veterans’ palms.

Many of those bikes have been “civilianized”, which finally gave approach to the primary wave of do-it-yourself customized bobbers, after which the very popular trend of custom choppers. The elevated variety of Liberators on U.S. streets finally led to the formation of bike golf equipment and gangs, a lot of which have been composed of dissatisfied GIs getting back from service aboard custom-made WLAs. Modifying WLAs was so fashionable within the post-war period that this can be very troublesome to search out an authentic Liberator as we speak.

Today, the adventure bike market is so big that nearly each producer desires in on the motion. Even Harley-Davidson’s Pan America 1250 is one of the biggest contenders to tear up occasional grime tracks. However, given the Liberator’s army and off-roading background, it could possibly be argued that the WLA was unofficially Harley-Davidson’s first journey bike. Considering it was designed to be as highly effective and sturdy as doable whereas working by way of all terrains, the Liberator definitely had some acquainted DNA that one would discover in a contemporary journey bike. Perhaps it could possibly be narrowed right down to the truth that the WLA was meant extra for service and obligation, whereas your common ADV bike is for enjoyable and pleasure.

The Unmatched History Of The Jeep Wrangler

Summary

  • Jeep Wrangler has a rich history dating back to WWII and has remained true to its off-road roots, giving it an edge over competitors.
  • The YJ Wrangler, produced from 1987-1995, featured a unique design with square headlights and a shift away from V-8 engines.
  • The TJ Wrangler, produced from 1997-2006, returned to the classic round headlights and introduced advanced features like airbags and a four-corner coil suspension.

Jeep has been building rugged off-road vehicles since it answered the call for Uncle Sam in WWII. This led to decades of development to improve what already was a very capable rig. Even today one can find old military Willys Jeeps all over the rocky and hilly terrain of America, and conquering those landscapes. The off-road lifestyle is popular in States like Utah, California, Arizona, and Colorado, with even Alaska and Hawaii in the mix, among others.

The Willys merged into the CJ model, which has been referred to as “Civilian Jeep.” This then yielded to the first Wrangler, 1987’s YJ. From there the models are codenamed TJ, JK, and JL. The TJ is arguably the best, although the newer JK and JL models provide unmatched technology in build and features. The Wrangler is a vehicle that remains true to its roots, at least as much as possible, in an evolving automotive environment. Due to this, and the fact that it has remained in constant production, gives the Wrangler an edge over any would be competitor.

The First Wrangler: A YJ Designation

Running from 1987-1995, the YJ Wrangler looks a bit weird compared to other Jeeps. The vehicle did away with the classic round headlight look of Jeeps past, while keeping the iconic seven slot grill, a Jeep mainstay. It also has wipers that rest at an angle on the windshield. In some Jeep circles it may be called a “Yuppie Jeep.”

Still, the body looks very much like a CJ, and it is definitely recognizable as a Jeep. People either hate the square headlights, or love them as a unique feature. The YJ also did away with the V-8 engines from AMC that the CJ used, setting a precedent for the Wrangler that would carry through the next generation, and that is the inline-six cylinder engine.

The YJ came with a four cylinder option, but it’s the inline-six cylinder that should be sought after, specifically the High Output 4.0 Liter that came about in 1991. This engine was fuel injected besides an increase in output, and was the top engine choice throughout even the TJ generation. Note that these are more common output figures, but they vary dependent on model and year, even though most older Wranglers will have the 2.5-liter or 4.0. Transmission types and specs also vary.

Despite it’s unique features, the YJ was very adaptable. With the turn signals integrated into the grill, the front fenders could easily be removed from the tub, to add high clearance flat steel fenders for example. Want more lift? Simply flip the leaf springs that are on all four corners on top of the axles, making what’s called a spring over axle lift, instantly and easily adding inches of ground clearance in the process.

Also of note, 1992 featured the first stock Jeep roll cage that was extended all the way to the back of the tub, providing added protection for the rear bench seat passengers in the event of a roll-over. It was the 1992 Sahara model that was featured in the film Jurassic Park. Today the YJ is its own sought after dinosaur, as an easy and cheap builder.

Besides the four-cylinder engine, another weak point of the YJ was the stock Dana 35 rear axle, which would require at least a build up for larger tires. If one wants to run 35-inch tires or more, an axle swap is definitely worth looking into. Equipped with a five-speed manual or three-speed automatic transmission, larger tires often necessitates axle re-gearing as well. The same principles apply to the TJ, the next still relatively simple Wrangler, but one that remains familiar.

The TJ Signifies “Top Jeep”

The TJ existed from 1997-2006, as there was no 1996 model Wrangler. The vehicle returns the look of the Wrangler to the classic round headlights of the Willys and CJs before it, and the wipers now sit flush with the bottom of the windshield as they normally would. Besides that, it is very similar looking to the YJ, but the turn signals have now moved onto the fenders, which are still just bolted to the tub that is frame mounted. Of course the top and doors are fully removable, and the top can be hard, soft, or of bikini variation.

The TJ is very accepting to mods, from appearance to off-road performance, and the aftermarket availability is grand. Not to mention the junkyard gems! Like the YJ, the TJ employs full- or half-door options. The interior is completely redesigned, however, and the vehicle features the added safety of airbags for the first time. Another Wrangler first, the TJ employs the use of an advanced four-corner coil suspension setup. By 2000, the 4.0-liter featured 190 horsepower with 235 pound-feet of torque, solidifying it’s status as a kick-ass engine.

Orange Jeep Wrangler TJ Rubicon

The advent of the Rubicon in 2003, resets the off-road market, which again experiences a seismic shift with the simultaneous addition of the “LJ” model. The Rubicon featured:

  • 31-inch tires
  • Dana 44 axles
  • 4.10 axle gears
  • Front and rear on-demand axle lockers
  • Unique Diamond plate rocker guards
  • 4:1 low range transfer case

The Rubicon trim was designed to take on the Rubicon trail in California right out of the gate, hence the name. The LJ, or “Long Jeep,” is officially a TJL. It’s the first Wrangler Unlimited, and has a 10-inch longer wheelbase than the regular TJ. Also, it has 15-inch longer tub, giving the vehicle more cargo space especially behind the rear bench seat.

Looking more like the CJ-8 Scrambler, the extended wheelbase adds some buildup potential. The longer wheelbase makes it easier to remain steady on steep grade climbs, even though it makes for a more shallow break-over angle. Want to add a doubler, or splitter, for more gearing options? It’s a lot simpler with the added wheelbase of the Unlimited over the base TJ body and frame.

The TJL Rubicon was only available for two years from 2005-2006, making this Wrangler the unicorn among all Jeeps. The LJ set up is so desired that aftermarket companies actually make kits to covert TJs to TJL dimensions. However, keep in mind that a regular TJ or LJ can be built to a higher standard more cheaply than a Rubicon. Just be sure to have a good base builder, one with a Dana 44 rear axle and 4.0 Liter engine, with the transmission of choice. All Unlimited Wranglers, Rubicons or not, came with such a configuration.

A JK: The First Four-Door Wrangler

The next-gen Wrangler, the JK, became the first one to feature a four-door option. This was a popular choice, as bigger SUVs and trucks were becoming the norm, but it’s a change that leads many Jeepers to call the TJ the “last of the real Jeeps.” Of course, a two-door option still exists, but the four-door is the new Unlimited.

There are other reasons too, for one the 4.0-liter is gone, replaced eventually by the balanced 3.6-liter Pentastar (a 3.8-liter was used until 2011). This being a V-6 motor with 285 horsepower, and 260 pound-feet of torque, the new top engine. A six-speed manual was available, a type which was first installed in a Wrangler in 2005, during the prior TJ gen. The other option was a five-speed auto. Also, the fenders are now a part of the body structure, and not easily removable.

Given that off-road Jeepers want bare-bones vehicles, a Wrangler with power windows may be frowned upon. You can thank the JK for bringing standard touchscreens to the Wrangler. These are the types of changes that came about with the JK, or is it “Just Kidding” generation?

All jokes aside, the JK Wrangler remained red-hot, and one won’t find any lacking number alongside any other Jeep on the trails or streets. Indeed, the JK sold from 2007-2018, oddly enough alongside the next-gen JL introductory year. Still with solid front and rear axles, removable top and doors, fold down windshield, and all the main Rubicon goodies of the original Rubicon TJ, the JK remained a 4×4 with capabilities that perhaps only another Wrangler could match out of the box. This Wrangler must mean “Just Killer.”

The JL Further Takes The Wrangler Into The Modern Tech Realm

The JL Wrangler, the latest and current generation, definitely modernized the vehicle as a whole. Not only did the consumer receive a factory 392 HEMI monster, something that Jeepers have clamored about for years, but also the first hybrid Wrangler arrived. Known as the 4xe, pronounced “four-by-E,” this hybrid Wrangler is the most powerful one to date besides the 392. Equipped with an industry first (for a plug-in hybrid), front and rear locking differentials, it also is the top-selling plug-in hybrid electric vehicle (PHEV) in America.

It’s safe to say that the JL is “Just Leading” all the competition. The only other new vehicle today like it is the Ford Bronco, one that has been recently revived after years at rest. The latter simply does not provide the pedigree of the former, nor has it gained as much trust among off-road enthusiasts, for the Wrangler remains the top choice for an off-road SUV.

All this technology and resulting capability is impressive, but it further complicates a historically simple machine, especially in the 4xe trim. Furthermore, it may be over-kill for what most need from a Wrangler. Even so, the options exist to reflect a changing market. This means some will hold on to their older variants, but that also new buyers will be attracted to Jeep like never before. As if a 392 and hybrid aren’t enough choices, a 2.0-liter turbo, and 3.0-liter EcoDiesel were also available alongside the 3.6L carryover.

Overall the options and capabilities presented are higher than ever, making it possible to meet any obstacle, and overtake it. People have been paying a premium for these rugged vehicles for years, because they know what Jeep’s “trail rated” badge signifies, always being the ones to say “only in a Jeep.” Today it really is true that someone can have their Jeep how they want it, regardless of budget, within the complete historical lineup of the venerable Wrangler.

The Unmatched History Of The Jeep Wrangler

Summary

  • Jeep Wrangler has a rich history dating back to WWII and has remained true to its off-road roots, giving it an edge over competitors.
  • The YJ Wrangler, produced from 1987-1995, featured a unique design with square headlights and a shift away from V-8 engines.
  • The TJ Wrangler, produced from 1997-2006, returned to the classic round headlights and introduced advanced features like airbags and a four-corner coil suspension.

Jeep has a long and storied history of building rugged off-road vehicles, starting with its participation in World War II. Over the years, Jeep has continuously improved its vehicles, particularly the Jeep Wrangler, to make them capable of conquering even the toughest terrains. Today, you can still find old military Willys Jeeps as well as the latest Jeep Wrangler models roaming the rocky and hilly landscapes of America, especially in states like Utah, California, Arizona, and Colorado, among others.

The Willys Jeep eventually evolved into the CJ (Civilian Jeep) model, which then gave way to the first Wrangler, known as the YJ, in 1987. This was followed by the TJ, JK, and JL models. While the TJ is often considered the best, the newer JK and JL models offer unmatched technology and features. Regardless of the specific model, the Wrangler has managed to stay true to its original off-road roots, which sets it apart from its competitors. Additionally, the fact that the Wrangler has remained in constant production gives it an edge over other vehicles in its class.

The YJ Wrangler, produced from 1987 to 1995, had a unique design featuring square headlights, a departure from the traditional round headlights of old Jeeps. Despite the unconventional headlights, the YJ still retained the iconic seven-slot grille. It also introduced changes like the removal of V-8 engines in favor of the more fuel-efficient inline-six cylinder engine. The YJ Wrangler was a divisive model, with some loving its distinctive features and others criticizing it as a “Yuppie Jeep.”

The YJ Wrangler came with various drivetrain options, including the four-cylinder engine and the preferred inline-six cylinder engine, particularly the High Output 4.0 Liter variant introduced in 1991. The YJ was versatile and highly customizable, allowing owners to modify it to suit their off-road needs. However, it did have some weak points, such as the stock Dana 35 rear axle, which could require upgrades for larger tires.

The TJ Wrangler, produced from 1997 to 2006, marked the return of the classic round headlights and brought significant advancements to the Wrangler line. It introduced features like airbags for added safety and a four-corner coil suspension, which improved the vehicle’s ride quality both on and off-road. The TJ Wrangler was highly adaptable and had a thriving aftermarket that offered numerous modifications to enhance its performance and appearance.

The TJ Wrangler also saw the introduction of the Rubicon trim, which became popular among off-road enthusiasts. The Rubicon trim featured upgrades like 31-inch tires, Dana 44 axles, 4.10 axle gears, front and rear on-demand axle lockers, and a 4:1 low-range transfer case, making it capable of tackling even the toughest trails. Additionally, the TJ generation saw the debut of the Wrangler Unlimited, known as the LJ, which had an extended wheelbase and increased cargo space.

The JK Wrangler, produced from 2007 to 2018, was a game-changer for the Wrangler line. It offered the option of a four-door configuration, making it more practical for families and those who desired additional space. The JK Wrangler also introduced the balanced 3.6-liter Pentastar V-6 engine, which replaced the iconic 4.0-liter inline-six engine. The JK Wrangler featured advancements in technology, including standard touchscreens and integrated power windows. It remained a highly capable off-road vehicle with solid front and rear axles, removable top and doors, and various trim levels, including the Rubicon with additional off-road-oriented features.

The latest generation of Wrangler, known as the JL Wrangler, has further modernized the vehicle. It offers a wider range of engine options, including the powerful 392 HEMI V-8 engine and the hybrid 4xe variant. The 4xe Wrangler is the most powerful hybrid Wrangler to date and has become the top-selling plug-in hybrid electric vehicle in America. The JL Wrangler introduced advanced features like front and rear locking differentials, making it even more capable off-road.

Despite the increasing complexity of the Wrangler and the availability of various options, it continues to maintain its status as the top off-road SUV. Jeep enthusiasts appreciate the Wrangler for its off-road capabilities and the freedom to customize it according to their preferences and budget. Whether it’s an older model or the latest generation, the Wrangler remains an iconic and sought-after vehicle for those who embrace the off-road lifestyle.
