Fits behind TH400/4L80-4×2 Transmissions

The Problem
Larger diameter tires on race trucks require higher numerical ring and pinion ratios — the higher the ratio, the less strength. This is due to increased gear tooth surface  speed and the resultant heat. Under tough race conditions, it isn’t unusual for the ring and pinion to fail. This kind of failure can be extremely costly, and not just because you lost a race. Replacement is expensive.

The rx-TorqueBox Solution
The rx-TorqueBox is the solution — with its sheer brute strength, it will create the perfect gearing combination to prevent catastrophic failure — no matter what size tires you are running. Designed specifically for the pounding a vehicle can take in off-road racing, from Baja to Dakar and everything in between. This high endurance unit will see your truck across the finish line every time. This reduction gear box is Torque Tough to the Extreme!​
