Chevy OBS Prerunners: A Classic Off-Road Icon

The world of prerunners—trucks built specifically to pre-run off-road racecourses before the main event—is rich with different makes and models. While the Toyota Tacoma continues to dominate this scene due to its ongoing production and legendary reliability, the Chevrolet OBS (Old Body Style) trucks, specifically from 1988 to 1998 (the GMT400 platform), remain a nostalgic favorite among off-road enthusiasts. Though not growing in popularity per se, Chevy OBS trucks have a loyal following for their rugged look, simplicity, and solid performance on rough terrain. This article dives into the details of what makes Chevy OBS trucks a strong choice for prerunner builds, and how they compare to modern alternatives like the Toyota Tacoma.

What is an OBS Chevy?

The term “OBS” stands for “Old Body Style,” referring to the classic, boxy design of Chevrolet’s trucks from the late 1980s through the 1990s. These trucks were produced on the GMT400 platform, and the most notable models are the Chevrolet Silverado and GMC Sierra from 1988 to 1998. Known for their angular design, powerful V8 engines, and simplicity, these trucks became iconic in the world of American pickups.

OBS trucks were built with durability and utility in mind, making them ideal candidates for conversion into prerunners. Their heavy-duty frames can be reinforced and outfitted with long-travel suspension systems, and the availability of V8 power gives them an edge when it comes to performance in wide-open desert racing environments.

Why Build a Chevy OBS Prerunner?

For off-road enthusiasts who gravitate towards Chevy OBS trucks, the appeal isn’t necessarily about trying to outpace newer models like the Toyota Tacoma. Instead, the attraction lies in their vintage aesthetics, V8 power, and straightforward mechanical systems that are easy to modify. Here’s why Chevy OBS trucks continue to see use as prerunners:

1. Durability and Engine Power

Chevy OBS trucks come equipped with large, durable frames and powerful V8 engines, such as the 5.7L small-block V8, which produces significantly more horsepower and torque than the smaller V6 engines typically found in Toyota Tacomas. This makes the OBS ideal for high-speed desert runs where raw power and torque are more important than nimbleness or fuel economy. The OBS trucks’ simple engine setups also make them easier to work on, especially for enthusiasts who enjoy building or modifying their trucks.

2. Aftermarket Support

Though newer trucks like the Tacoma benefit from a constantly evolving aftermarket, the Chevy OBS has strong aftermarket support as well. From lift kits and long-travel suspension systems to performance upgrades, the OBS Chevy has a well-established base of enthusiasts and companies catering to off-road modifications. Aftermarket fiberglass fenders, suspension kits, and off-road bumpers are widely available for these trucks, making it relatively easy to turn an old Chevy into a capable prerunner.

3. Classic Looks

One of the biggest draws of the Chevy OBS trucks is their nostalgic design. For many enthusiasts, it’s not about trying to keep up with modern trucks, but instead embracing the rugged, boxy aesthetic that defined pickup trucks of the 1990s. The OBS Chevy’s sharp lines and vintage appeal are favored by those who appreciate classic vehicles and want a prerunner that stands out at events or on the trails.

How Chevy OBS Prerunners Compare to Toyota Tacomas

While Toyota Tacoma prerunners dominate in sheer numbers, there are several key areas where the Chevy OBS offers something different for those interested in building a prerunner.

Engine Performance

• Chevy OBS: Most Chevy OBS trucks come with V8 engines, which deliver superior torque and horsepower compared to the V6 engines typically found in Toyota Tacomas. This additional power can be a significant advantage when running at high speeds through open desert areas.
• Toyota Tacoma: The Tacoma, particularly newer models, come with reliable V6 engines known for their fuel efficiency and longevity. While they may not offer the same raw power as the OBS, they make up for it in reliability and modern technology, like traction control systems and advanced suspension options.

Size and Weight

• Chevy OBS: OBS trucks are generally larger and heavier than Tacomas, which can be both a pro and a con. The added size allows for more substantial suspension setups and larger tires, but the extra weight can make them less nimble on tight trails or technical off-road sections.
• Toyota Tacoma: Tacomas are smaller and lighter, making them easier to maneuver through technical terrain, narrow trails, and rocky environments. This nimbleness, combined with modern off-road technology, makes Tacomas the preferred choice for those who need a truck that can tackle a variety of off-road conditions.

Aftermarket Customization

• Chevy OBS: While the OBS Chevy doesn’t have quite the same level of aftermarket development as the Toyota Tacoma, it still enjoys strong support, especially in terms of suspension and body modifications. Enthusiasts can find parts designed to improve the truck’s performance and durability in off-road settings.
• Toyota Tacoma: Tacomas benefit from a vast and continuously growing aftermarket community. Companies like Total Chaos and King Shocks have dedicated entire product lines to Tacoma owners, offering everything from long-travel kits to coilovers, roof racks, and performance upgrades.

Durability and Longevity

• Chevy OBS: These trucks are known for their durability, especially the solid GMT400 frame. However, since they’re older, finding one in good condition often requires a thorough search or a significant investment in restoration. Once restored or modified, these trucks are built to withstand heavy off-road use, but they don’t have the same longevity reputation as Toyota.
• Toyota Tacoma: Tacomas are famous for their longevity, with many trucks racking up hundreds of thousands of miles with minimal issues. The lighter frame and simpler mechanics of the Tacoma make it more durable in extreme off-road situations where the OBS might suffer from its heavier build.

Notable Chevy OBS Prerunner Builds

Some standout OBS Chevy prerunner builds showcase the full potential of these trucks when outfitted for desert racing and off-road adventures. Here are a couple of noteworthy examples:

1. Camburg Engineering’s Chevy OBS Prerunner

Camburg Engineering is a leader in off-road suspension systems, and they’ve built a few impressive Chevy OBS prerunners. Camburg typically equips these trucks with custom long-travel suspension systems, bypass shocks, and reinforced chassis to withstand the rigors of desert racing. Their builds also often feature engine swaps, such as an LS-series V8, which offers massive power for high-speed runs through the desert.

2. Baja Kits Chevy OBS

Baja Kits has produced several Chevy OBS-specific long-travel kits designed to maximize the off-road potential of these older trucks. Their prerunners often feature custom long-travel suspension setups, upgraded shocks, and reinforced frames. These builds prioritize durability and performance, ensuring the truck can handle extended abuse in harsh desert environments.

The Role of Chevy OBS Prerunners in Today’s Off-Road Scene

While the Toyota Tacoma continues to be the go-to choice for many in the off-road and prerunner communities, the Chevy OBS remains a beloved classic for those who prefer something with a little more personality and power. These trucks aren’t competing directly with newer Tacomas in terms of technology or agility, but for enthusiasts who value classic design and raw V8 power, they represent a unique, nostalgic alternative.

OBS prerunners occupy a niche within the off-road world. They appeal to those who love vintage vehicles, enjoy customizing trucks from the ground up, and appreciate the aesthetic of old-school off-road machines. For these enthusiasts, the Chevy OBS prerunner will always have a place in the off-road community, not because it’s “catching up” to Toyota, but because it embodies the rugged, classic American truck spirit.

Chevy OBS prerunners may not be the future of the prerunner scene, but they certainly have carved out a place in its history. With their classic styling, powerful V8 engines, and strong aftermarket support, they offer a compelling option for off-road enthusiasts who appreciate the old-school appeal of these trucks. While modern trucks like the Toyota Tacoma may be more practical for many, the OBS Chevy remains an iconic choice for those who love the combination of raw power, durability, and timeless design.
