Everything You Need To Rebuild It Right The First Time

When it comes time to rebuild your rear differential, the last thing you want is to be chasing down missing parts or second-guessing the quality of what’s going in. The Yukon YKGM11.5-B Master Overhaul Kit is built to take all the guesswork out of the job. It includes everything you need in one box, from premium Timken bearings and races to high-quality seals, a complete shim kit, thread locker, and even marking compound with a brush. It’s designed specifically for GM 11.5 inch differentials from 2011 to 2019, and Dodge Ram 2500 and 3500 models from 2011 to 2013, so you know you’re getting the right parts for your application. Whether you're installing new gears or replacing worn-out internals, this kit ensures a proper, long-lasting setup that won’t leave you second-guessing your install. Yukon doesn’t cut corners on quality or fitment, which means fewer headaches and more time back on the road. If you're already taking the time to open up the rear end, this is the kit that makes sure you only have to do it once.

Precision Matched Components For Your 11 Point 5 Axle

This Yukon master kit is purpose-built for the 11.5 inch full-float differentials found in GM and Chrysler HD trucks, ensuring every component is tailored to meet the specs of your axle. It includes both carrier and pinion bearings, along with matching races, seals, a pinion nut, ring gear bolts, and a crush sleeve to help dial in correct preload. Yukon uses Timken bearings for proven strength and reliability under load, which makes a big difference in high-torque applications like towing, hauling, or upgraded gear installs. The included shim kit and thread locker help you achieve the right setup with fewer adjustments during the process. This specific kit is designed for the updated mid-2011 and newer pinion bearing design that uses a 4.375 inch race, which is a critical detail to ensure proper fit. With the addition of silicone and marking compound, this truly is a complete overhaul solution for anyone doing a full rebuild. Whether you’re a shop tech or tackling it at home, the YKGM11.5-B gives you the confidence to rebuild your axle with precision.
