Upgrade your OBS truck’s chassis strength and handling with our premium frame stiffener. Engineered with precision-fit boxing plates, this 100% bolt-in kit reinforces your factory frame to reduce flex and improve overall rigidity—delivering a smoother, more responsive driving experience.
This frame stiffener installs easily with no welding, using existing factory holes to locate components for a true bolt-in upgrade. The heavy-duty steel boxing plates are designed to strengthen key areas of the frame, helping to prevent twisting and flexing under load or during aggressive driving. The added rigidity improves cornering, braking, and overall vehicle control, whether you’re daily driving, or pushing your truck on the road or track. Built from high-grade steel, this system is made to last and deliver consistent performance over time.
The ultimate solution to improve strength, stability, and handling in your OBS chassis.
Note: The factory fuel tank will need to be relocated to the rear of the truck.
