Yukon 11.5in AAM 4.56 Rear Ring & Pinion Install Kit 4.375in OD Pinion Bearing

Yukon Gear & Axle has built a reputation for quality in the automotive gear industry, and this comprehensive kit is a prime example of their commitment. If you're looking to re-gear your differential for increased tire size, better towing power, or to replace worn-out components, this package bundles everything you need into one convenient part number. It's designed for a range of vehicles, including models like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Ram 2500.

This kit features a 4.56 ratio ring and pinion gear set specifically for 11.5-inch AAM rear differentials. Yukon engineers use advanced heat-treating techniques and rigorous quality testing to ensure their gears meet exacting specifications for structure and surface finish. You'll also receive a Yukon Master Overhaul Kit, which includes high-quality Timken bearings and all the necessary small parts. This means you get all the components required to fully rebuild your differential and get your vehicle back on the road quickly.

By combining the premium Yukon ring and pinion set with a comprehensive installation kit, Yukon saves you time and money compared to sourcing each part individually. The kit includes the specific NP673386/NP516549 inner pinion bearing and race, which has a 4.375-inch outside diameter. Yukon also backs this gear set kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for as long as you own your vehicle.
