Fitment Notes

Fits both AAM 11.5" and AAM 11.8" differentials - cover bolt pattern is shared across both axle variants
GM and Dodge/Ram AAM 11.5" axle assemblies are not interchangeable due to differences in axle tubes, hubs, and suspension mounting; however, this cover fits both
Ram 2500/3500 models with the 2013.5+ 6.7L Cummins paired with Aisin automatic transmission use the 11.8" (300mm) variant - this cover fits that application as well
2014+ Ram 2500/3500 coil spring suspension models use a revised AAM axle assembly; verify rear suspension type (leaf vs. coil) before ordering
Always verify the AAM 11.5" axle is present in your specific vehicle - not all HD trucks in these year ranges use this differential

Product Description

The Yukon YHCC-AAM11.5 Hardcore Differential Cover is engineered for the AAM 11.5" and 11.8" rear differentials found in heavy-duty GM and Dodge/Ram 3/4-ton and 1-ton trucks. Built from thick-walled nodular iron, this cover withstands the rock strikes, trail abuse, and road debris that crack or destroy factory stamped-steel covers. The reinforced design also adds structural rigidity to the differential housing, reducing ring and pinion deflection under the high-torque loads common in diesel towing, payload hauling, and off-road use.

Installation is a straightforward bolt-on replacement using the factory cover bolt pattern. The included magnetic drain plug captures metallic particles suspended in the gear oil between service intervals, and high-strength steel fasteners ensure a secure, leak-free seal. The black powder coat finish and stainless-steel accent plate deliver both durability and style. Whether you're running a Duramax, Cummins, or gas-powered HD truck, this cover is a proven upgrade for anyone looking to protect one of the most capable heavy-duty rear axles in production.
