AFE Power Pro Series AAM 9.5/9.76 Rear Differential Cover Black with Machined Fins 20-23 GM 3.0L 1500 Duramax
Description
Pulling a heavy trailer or hauling a loaded bed puts the rear gears to work and builds heat in the gear oil. The aFe POWER AAM 9.5/9.76 Rear Differential Cover holds more gear oil than the factory cover. The cast aluminum body and its internal and external fins help transfer heat from the gear oil to the surrounding air.
Both finishes include a magnetic drain plug to help catch iron and steel particles and a calibration port that gives you a reference for the factory fill level. The black Pro Series version also includes a sight glass for quick oil-level checks and a deep-reach magnetic fill plug. Mounting hardware is included, and the installation instructions call for reusing the factory gasket.
Fitment note: Fits only the 12-bolt AAM 9.5 or AAM 9.76 rear axle. Verify the rear axle before ordering. For the GMCH 9.5 rear axle, use the aFe 46-71140 series cover.
