Wide Open Design chassis are engineered for serious off-road enthusiasts who demand proven performance, durability, and capability on the trail, in competition, and everywhere in between. Designed and manufactured in Tennessee, our tube chassis platforms are built from decades of real-world experience in rock crawling, rock bouncing, trail riding, and off-road racing.
Whether you're building a dedicated rock crawler, rock bouncer, Ultra4-style buggy, Jeep-based trail rig, or custom off-road vehicle, this collection includes chassis options designed to match a wide range of applications and driving styles. From the Revolution Series and Rocketship Chassis to Jeep TJ, LJ, CJ, and YJ conversion chassis, every platform is engineered to maximize suspension performance, drivetrain packaging, durability, and serviceability.
