Description

The Yukon Minor Installation Kit offers a cost-effective solution for ring and pinion gear replacement in GM 8.6-inch IRS rear differentials, particularly in vehicles where the original bearings are still in good condition and can be reused. The kit is specifically designed for GM 8.6" IRS Camaro applications. Included within the package are a new pinion seal to prevent leaks, a crush sleeve for proper bearing preload adjustment, a comprehensive shim kit for precise gear meshing, and marking compound with an accompanying brush for accurate pattern checking during installation. This Yukon installation kit is a product of Yukon Gear and Axle, a recognized brand in drivetrain components.
