Yukon 8.6in GM 4.88 Rear Ring & Pinion Install Kit Axle Bearings and Seal

Starting with the 8.5-inch ring gear diameter, this Yukon Gear & Axle kit is built for serious re-gearing projects. If you're looking to change your differential ratio, perhaps to accommodate larger tires, improve towing capacity, or enhance off-road performance, this package bundles everything you need into one convenient part number. It's designed for vehicles with a 10-bolt rear cover and a 10-bolt ring gear, covering a wide range of GM trucks and SUVs from the late 90s through the late 2000s, including popular models like the Chevrolet Silverado 1500 and GMC Sierra 1500.

Inside this kit, you'll find a high-performance 4.88 ratio Yukon ring and pinion gear set. These gears are manufactured using advanced heat-treating techniques and undergo rigorous quality testing to ensure they meet exacting specifications for strength and surface finish. Alongside the gears, the kit includes a Yukon Master Overhaul Kit, which contains high-quality Timken bearings and all the necessary small parts for a complete differential rebuild. This means you get the carrier bearings, races, pinion bearings, seals, and gaskets all in one box, saving you time and hassle during installation. The inclusion of axle bearings and seals further ensures you have all the critical components for a successful re-gear.

This comprehensive package is designed to get your vehicle back on the road quickly after a re-gear. Yukon Gear & Axle also backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set. This provides significant peace of mind for such a critical drivetrain component.
