When you're looking to re-gear your differential, whether it's to handle larger tires, improve towing capacity, or just replace worn-out parts, a complete kit like this Yukon YGK2039 package makes the job much smoother. This kit is built around a 3.73 ratio ring and pinion gear set designed for the 8.8-inch Ford rear axle, and it includes a Yukon Dura Grip clutch-style limited-slip differential to help put power down effectively. It’s designed to fit a wide range of Ford vehicles, including popular models like the Ford Bronco, F-150, and Mustang.

Yukon engineers their ring and pinion sets with advanced heat-treating techniques and rigorous testing to ensure they meet exacting specifications for structure and surface finish. This particular kit comes with high-quality Timken bearings and all the necessary small parts, like seals and gaskets, to fully rebuild your differential. The inclusion of the Dura Grip limited-slip unit means you get a fully rebuildable positraction unit that’s ready for demanding use. The inner pinion bearing features a 3.250-inch outside diameter, and the kit is designed for axles with a 10-bolt ring gear and a 10-bolt rear cover.

This comprehensive package saves you time and money by consolidating all the essential components into a single part number. Yukon also backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set kit, giving you added confidence in your purchase for as long as you own your vehicle.
