Product Description

The Yukon Gear & Axle CK GM8.5-HD is a dedicated carrier installation kit designed to facilitate the installation of aftermarket carrier units in GM 8.5" differentials. It provides heavy-duty Timken bearings and races tailored for large-journal carriers, along with a precision shim kit to optimize preload and ensure proper gear alignment. Compatible with Yukon DuraGrip limited-slip, Eaton Posi, ValueTrac, TrueTrac, Pro-Series Auburn, Detroit Locker, and similar units, this kit provides a dependable and cost-effective solution when upgrading your axle's traction system.

Ideally suited for enthusiasts and mechanics performing carrier swaps - whether converting to a limited-slip or mechanical locker - this kit eliminates the need for the full overhaul kit when the pinion and ring gear are already set. Installation requires basic differential tools and mechanical experience; shims must be adjusted to maintain correct bearing preload and backlash. It's an ideal choice for vintage GM builds using the 8.5" 10-bolt axle, especially in light-duty trucks and passenger cars from the 1970s and '80s.
