What is a prerunner truck and how to build it right?

Ford F150 prerunner racing in the desert

In modern automotive culture, the term “prerunner” refers to a specific style of truck modification that draws inspiration from off-road racing vehicles. These modifications include upgrades that allow the truck to be driven at high speeds across desert terrain. Compared to regular lifted trucks, prerunners prioritize suspension travel and damping over increased ground clearance, as these factors play a crucial role in their performance.

Over the past few years, we have featured dozens of awesome prerunners, both DIY and professionally built, based on compact truck platforms like the Toyota Tacoma, Ford Ranger, and Chevrolet Colorado, as well as more common full-size platforms such as the Chevrolet Silverado, Ford F-150, Toyota Tundra, and Nissan Titan. After speaking with the owners and thoroughly examining the extensive lists of upgrades made to these trucks, we have compiled the following list of modifications that set prerunners apart from other off-road builds:

  1. Suspension: Most prerunner trucks feature extensive suspension upgrades, including long-travel kits, coilovers (often from King or Fox), bypass shocks, and custom control arms. These modifications significantly increase wheel travel and improve off-road performance.
  2. Engine: While some builds retain the stock engine (mostly V8s, since they provide sufficient performance), many feature performance upgrades such as cold air intakes, performance exhausts, and ECU tuning. Some builds even swap in larger or more powerful V8s and install superchargers.
  3. Wheels and Tires: Prerunner trucks typically run large, off-road tires (35″-37″) mounted on beadlock wheels to handle rough terrain and prevent tire de-beading.
  4. Exterior: Many prerunners feature fiberglass body panels, such as fenders, bedsides and hoods, to accommodate the increased wheel travel and provide clearance for larger tires. Custom front and rear bumpers with integrated skid plates are also common as they improve the approach and departure angles.
  5. Safety: Full roll cages, often extending from the front to the rear of the vehicle, are a common addition for driver and passenger safety. Racing seats with multi-point harnesses are also frequently installed.
  6. Lighting: Auxiliary lighting, such as light bars, pod lights, and dust lights, is often added to improve visibility during night runs.
  7. Interior: Custom center consoles, switch panels, and racing-inspired steering wheels are popular interior modifications.

In conclusion, the most common prerunner truck modifications focus on improving off-road performance, durability, and safety, with an emphasis on suspension upgrades, engine enhancements, and exterior changes to accommodate the demands of high-speed desert running.

Prerunner in Offroad Racing

In the context of off-road racing, a “prerunner” is a vehicle, typically a truck or buggy, that has been modified specifically for high-speed off-road driving (often desert terrain). These vehicles are used by racers to pre-run, or test run, the course before competitions, allowing them to familiarize themselves with the terrain and identify potential hazards without risking damage to their primary race vehicle.

While a prerunner may be similar to the actual race truck in terms of design and functionality, it is usually simpler in terms of performance and construction. This simplicity allows for easier maintenance and repairs, as well as lower costs compared to the highly specialized and expensive race vehicles.

Interesting fact: Spence Murray was the first winner of the Baja 1000. He was driving a Rambler American, which was way far from being the fastest truck in the race. Despite this fact, he won the race simply due to getting lost in the desert less than his competitors.

Prerunners in Modern Off-Road Culture

While it may be difficult to pinpoint the exact moment or event that catalyzed the widespread popularity of prerunners in the off-road community, it’s clear that their unique appeal lies in the high-speed, adrenaline-pumping experience they offer.

In contrast to the slow, methodical rock crawling typically done in a Jeep, prerunner trucks offer a completely different kind of thrill. If overlanding can be compared to a classic country song, then desert racing in a prerunner is undoubtedly the off-road equivalent of a rock anthem.

This exhilarating style of off-roading has resonated with a significant portion of the off-road community, particularly those who crave the rush of pushing their vehicles to the limit in challenging conditions. The allure of this fast-paced, high-flying adventure has undoubtedly contributed to the growing popularity of prerunners among off-road enthusiasts.

Common Modifications

We carefully inspected the parts lists on a dozen of various prerunner builds we featured on Offroadium during the last few years. Some of the builds were put together by DIY enthusiasts others built by professional shops. In this section, we summarized the key components used in these trucks and highlighted the brands selected by their builders.


The most common suspension modifications include long-travel kits, often with custom control arms, increased wheel travel ranging from 15 to 31 inches, and high-performance shocks. Fox and King shocks were the most frequently used brands, with coilovers (2.5″ to 3.0″ diameter) and bypass shocks (up to 3.0″ diameter) being the most popular options.

The Truck – Which Platform To Choose?

When choosing a truck for a prerunner project, consider the following factors:

  1. Aftermarket support: Select a truck with a wide range of available aftermarket parts, such as suspension components, body panels, and performance upgrades. Popular choices include Ford F-150, Chevy Silverado, Toyota Tacoma, and Toyota Tundra.
  2. Wheelbase: A longer wheelbase can provide better stability at high speeds and more room for suspension travel. However, a shorter wheelbase may be more maneuverable in tight off-road situations, think OBS Bronco or a K5 Blazer.
  3. Engine and drivetrain: Heavily oversized 35-37″ tires literally eat out all the momentum of the engine especially in deep sand. So we recommend choosing a truck with a reliable and powerful engine (preferably a V8 or modern hi-output turbo engines).
  4. Suspension design: Some trucks have suspension designs that are more conducive to prerunner builds. For example, Ford’s twin-traction beam (TTB) front suspension and Chevy’s independent front suspension (IFS) are popular choices.
  5. 2WD or 4WD: Prerunner builds can be based on either 2WD or 4WD trucks. 2WD trucks are typically lighter and simpler, making them popular for desert racing and high-speed off-road driving. 4WD trucks offer better traction and versatility, but they may be heavier and more complex to modify. Ultimately, the choice between 2WD and 4WD depends on your intended use and personal preferences.
