USA Standard Gear ZSG7589 Power Steering Gear Box with 33-Spline Output for 1999-2010 Chevrolet/GMC/Hummer

Fits select 1999-2010 Chevrolet Silverado, Suburban, and Avalanche 2500; GMC Sierra and Yukon XL; and Hummer H2. This power steering gear box is the definitive solution for vague handling, steering wander, or fluid leaks in your heavy-duty GM truck or SUV.

As these vehicles age, internal components in the steering gear wear down, resulting in imprecise steering, grinding noises, and a "floaty" feel that makes keeping the vehicle centered in your lane difficult. The USA Standard Gear ZSG7589 restores factory steering response and road feel. Unlike many options on the market, this unit is 100% new—not remanufactured—meaning you receive a gear box with zero internal wear and no core return required.
