Servicing an 11.5-inch rear axle on a 2019-2024 Silverado, Sierra, or Ram 2500/3500 truck? The AAM 74067032 Master Bearing Kit brings everything needed for a differential bearing job together in a single, Premium-grade part number.

Backed by American Axle & Manufacturing, an OE driveline supplier, this kit is built to fit correctly across 36 verified vehicle applications spanning gas and diesel engine configurations, including the Duramax L5P and Cummins 6.7L. Ordering the full kit helps reduce comeback repairs by ensuring all related bearing components are replaced together during the service.
