Product Description

The Yukon Gear & Axle YK GM8.5 Master Overhaul Kit is a comprehensive differential rebuild solution engineered specifically for GM 8.5" rear axles with 10-bolt pattern. Featuring premium Timken bearings and races, precision shims, hardware, seals, and setup compounds, it includes everything needed to fully rebuild your differential to OEM or better standards.

Designed for GM truck and SUV applications from the 1970s through early 2000s - including models across Chevrolet, GMC, Buick, Cadillac, Pontiac, Oldsmobile - the kit supports standard and aftermarket posi or locking carriers. Whether installed by a professional or experienced DIYer, the complete kit simplifies teardown and assembly while ensuring proper preload and backlash adjustment for reliable long-term operation.

All components are backed by Yukon's one-year limited warranty. Installation requires basic differential tools: torque wrench, bearing press/splitter, depth gauge, and dial indicator. Ideal when replacing worn bearings, upgrading to posi/locker setups, or refreshing internal wear items. Verify pinion spline count (28/30) and confirm housing depth before rebuild.
