Yukon Gear Crush Sleeve Eliminator Kit For GM 12 Bolt Car

When you're rebuilding the differential on your classic GM passenger car, getting the pinion bearing preload just right is critical for long-term reliability. This crush sleeve eliminator kit from Yukon Gear & Axle replaces the factory crush sleeve with a solid spacer, making it much easier to set and maintain the correct pinion preload during assembly.

This kit is designed specifically for the GM 12-bolt rear axle found in a wide range of vehicles, including models like the Chevrolet Impala, Pontiac GTO, and Buick Wildcat. By swapping out the crush sleeve for a precisely machined solid spacer, you eliminate the guesswork involved in setting preload. Once you determine the correct spacer length, it stays put, simplifying the setup process and ensuring consistent results. This makes it a popular choice for builders who want a more straightforward and repeatable way to achieve proper pinion bearing tension.
