Yukon 11.5in AAM 4.56 Rear Ring & Pinion Install Kit 4.125in OD Pinion Bearing

Starting with the 4.125-inch outside diameter of the inner pinion bearing, this Yukon Gear & Axle kit is designed for a specific re-gear project on a range of heavy-duty trucks. 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 the essential components. It's built for vehicles with an 11.5-inch ring gear diameter and a 14-bolt rear cover, commonly found on models like the Chevrolet Silverado 2500 HD, Dodge Ram 2500, and GMC Sierra 2500 HD from the early 2000s through 2010.

Yukon engineers their ring and pinion sets using advanced heat-treating techniques and rigorous quality testing to ensure they meet precise specifications. This kit combines these high-performance gears with a Yukon Master Overhaul Kit, which includes quality Timken bearings and all the necessary small parts for a complete differential rebuild. Having everything in one part number saves you time and money, streamlining the process of getting your vehicle back on the road with its new gear ratio.

This comprehensive package is ideal for anyone undertaking a differential re-gear. Beyond the gears and bearings, it contains all the small parts needed to ensure a proper installation. Yukon also backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set, offering significant peace of mind for the long haul.
