The PSC BIG BORE XD® Steering Gear Box is built for GMC 2500HD and 3500HD 4WD trucks that demand more steering control than the factory gearbox can deliver. Whether you're towing heavy loads, turning larger tires, or putting your truck through tough off-road conditions, this gearbox is designed to provide increased steering authority, improved durability, and a more confident feel behind the wheel.

Featuring PSC's larger piston design and heavy-duty internal components, the BIG BORE XD® helps deliver the steering assistance needed when tire size and vehicle weight push the limits of OE steering components. It's a proven upgrade for truck owners looking for stronger, more dependable steering performance both on and off the pavement.
