• Brand-new construction - not remanufactured. No core return required.
• Does not fit standard Silverado/Sierra 1500 (non-HD) models outside of the specific build years listed above.

Product Description

The Yukon / USA Standard ZSG7589 is a brand-new power steering gear box built for 2001-2010 GM HD trucks and SUVs, including the Chevrolet Silverado 2500 HD and 3500 HD, GMC Sierra 2500 HD and 3500 HD, Suburban 2500, Yukon XL 2500, Avalanche 2500, and Hummer H2. Built entirely with new components, it restores the responsive, precise steering feel that wears away over time as internal gear components loosen and degrade - eliminating the lag, drift, grinding, and binding that are telltale signs of a failing steering box.

Before ordering, verify your vehicle's sector shaft configuration. Two versions exist for these model years: ZSG7589 fits the 33-spline, 4-blank sector shaft, while ZSG8418 fits the 3-blank variant. Count the large gaps between splines on the sector shaft (the shaft protruding from the side of your current steering box with the pitman arm attached) to confirm the correct part. No core return is required, and the unit is backed by a 3-year / unlimited-mile manufacturer's warranty.
