Yukon 10.5in Ford 4.56 Rear Ring & Pinion Install Kit 35 Spline Positraction

Yukon Gear & Axle is well-known for making solid drivetrain components, and this complete kit is a prime example of their work. If you're looking to re-gear your 1999-2007 Ford F-250 Super Duty, whether it's to handle larger tires, improve towing power, or replace worn-out factory gears, this package has everything you need in one convenient part number. It includes a 4.56 ratio ring and pinion gear set specifically for the 10.5-inch Ford rear axle, along with a 35-spline Yukon Dura Grip clutch-style limited-slip differential.

This kit goes beyond just the gears. It contains a Yukon Master Overhaul Kit, which means you get all the necessary bearings, seals, and small parts required for a full differential rebuild. Yukon uses advanced heat-treating techniques and rigorous quality testing to ensure their ring and pinion sets meet exacting specifications for durability and performance. The included Timken bearings are also a mark of quality, known for their longevity. This comprehensive approach helps get your vehicle back on the road quickly and reliably after the re-gear process.

Beyond the core components, Yukon offers their Y.E.S. Plan, a lifetime protection plan for your gear set kit. This kit is designed for applications with a 12-bolt rear cover and ring gear, and it comes with the NP 504493/NP 949481 inner pinion bearing and race. Having all these high-quality parts bundled together saves you time and money compared to sourcing each component individually.
