Yukon 8.5in GM 4.11 Rear Ring & Pinion Install Kit 30 Spline Positraction Axle Bearings and Seals

If you're looking to change your differential gearing for better towing, to accommodate larger tires, or to improve off-road performance, a complete ring and pinion install kit is the way to go. This Yukon Gear & Axle kit is designed for 8.5-inch GM rear axles and includes a 4.11 ratio ring and pinion set, along with a 30-spline Yukon Dura Grip limited-slip positraction unit. It’s a comprehensive package that covers a wide range of GM trucks and SUVs from the late 80s through the early 2000s, including popular models like the Chevrolet C1500, GMC Yukon, and Cadillac Escalade.

This kit isn't just about the gears; it bundles all the necessary components for a proper differential rebuild. You'll find high-quality Timken bearings, essential seals, and all the small parts needed to complete the job. Yukon engineers use advanced heat-treating techniques and rigorous testing to ensure their ring and pinion sets meet exacting specifications for durability and smooth operation. The included Dura Grip limited-slip differential is fully rebuildable, offering improved traction for various driving conditions.

By combining the ring and pinion gears, master install kit, and a limited-slip differential into a single part number, Yukon makes the re-gearing process more convenient and cost-effective. This kit is backed by Yukon's Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set, giving you added peace of mind.
