Yukon 8.5in GM 3.73 Rear Ring & Pinion Install Kit 30 Spline Positraction Axle Bearings and Seals

Starting with the 8.5-inch ring gear diameter, this Yukon Gear & Axle kit is built for serious drivetrain work. It bundles everything you need to re-gear your rear differential, including a 3.73 ratio ring and pinion set, a Yukon Dura Grip clutch-style limited-slip differential, and a comprehensive master install kit. This kit is designed for vehicles with a 30-spline axle and a 10-bolt rear cover, fitting a wide range of GM trucks and SUVs from the late 80s through the early 2000s, such as the Chevrolet C1500, GMC Yukon, and Cadillac Escalade.

Yukon engineers their ring and pinion sets using advanced heat-treating techniques and rigorous quality testing to ensure they meet exacting specifications. The included master install kit features high-quality Timken bearings and all the necessary small parts, like axle bearings and seals, to complete the rebuild. This approach saves you time and money by consolidating all required components into a single part number, making the re-gearing process more straightforward. The Dura Grip limited-slip differential is fully rebuildable, offering a solid option for improved traction whether you're increasing tire size, enhancing towing capacity, or tackling off-road trails.

This kit is a substantial investment in your vehicle's drivetrain performance and durability. Yukon backs these components with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set kit. When undertaking a differential rebuild, always refer to the manufacturer's installation instructions for specific procedures and torque specifications.
