Differential Shims

Differential shims are essential for a proper ring and pinion gear setup. They are thin, precisely cut spacers that fit between the differential bearings and the housing. These shims adjust the backlash and carrier bearing preload, which are critical for smooth operation and long-term durability of your ring and pinion gears. Using the correct shim kit is crucial when installing a new ring and pinion or rebuilding a differential to ensure all components are properly aligned and perform as they should.

Properly setting up your differential with the right alignment shims prevents excessive noise and premature wear of the gears and bearings. Our selection includes metal shims and steel shims in various thicknesses, providing the exact fit you need for a wide range of axles. Whether you're a professional mechanic or a dedicated DIYer, having the right differential gear shims on hand ensures your driveline is built to last.
