The WOD Race Radiator is a serious-duty cooling package built for high-horsepower off-road vehicles that cannot afford cooling problems. This 38" x 17" x 3" TIG-welded aluminum radiator has been proven by Wide Open Design for more than 15 years in some of the harshest motorsports conditions, including Ultra4 race cars, competitive rock bouncers, Rocketship Rockbouncer chassis builds, Revolution chassis builds, and custom tube chassis applications.

This radiator package is large, but the cooling capacity is the reason it works. From big block Chevy engines to small block combinations, LS swaps, LT engine platforms, and high-output race builds, this radiator has been used in vehicles built around extreme heat, low-speed crawling, long hill pulls, wide-open throttle abuse, and severe-duty off-road use. If you are building a high-horsepower buggy, rock bouncer, Ultra4 car, or custom chassis and need proven cooling performance, this WOD Race Radiator package is built for that job.

Tech Insight

In extreme off-road applications, cooling problems usually happen when the vehicle is under the most load: slow technical climbs, long hill pulls, limited airflow, mud, dust, high ambient temperature, and repeated wide-open throttle abuse. This radiator package was chosen because it has the core size, fan power, coolant capacity, and durability needed for severe-duty use instead of just being a compact universal radiator.

The dual 16-inch SPAL puller fans provide a combined rated airflow of 3836 CFM, giving the radiator strong airflow support when vehicle speed is low or chassis airflow is restricted. The straight -16 upper and lower fittings make it easier to plumb into race cars, rock bouncers, and custom chassis builds that use AN-style coolant lines.
