RX-TORQUEBOX  

(For gas/diesel-powered trucks and extreme-duty ev) 

YOU CAN'T WIN IF YOU DO NOT FINISH

The rx-TorqueBox will take you across the finish line every time.

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

 

The Solution
The rx-TorqueBox is the solution. With its sheer brute strength, it will create the perfect gearing combination to prevent high gear tooth surface speed and 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 gearbox is Torque Tough to the Extreme!

The Application
The rx-Torque Box comes with a complete installation kit, including an HD mount plate, splined coupler, billet fixed yoke, mounting hardware, and a step by step installation guide/service manual.

Note: Units are shipped without lubrication, fill after installation...see manual enclosed with the product for details.
