Engineered with superior strength and protection in mind, AEV’s Heavy Duty Ram Differential Cover is the toughest on the market! Designed specifically for the AAM 11.5/12″ rear axle found in 2010+ HD trucks, theDodge RAM 2500/3500 rear differential cover features a vehicle specific fluid level verification port, placed at the correct level to meet factory specifications for the rear axle, eliminating the need to guess on oil levels or use a dipstick to figure out the correct amount of oil.

For added convenience, the Dodge RAM 2500/3500 rear differential cover utilizes AEV’s exclusive oversized fill port located on the top of the cover. This fill port not only allows you to easily add fluid in the field if axle repairs are necessary, but also doubles as an inspection port, allowing the user to see inside the differential, inspect ring gear teeth, look for water intrusion and even use a dial indicator to inspect for problems without ever removing the cover.

These covers are compatible with the following applications

10404021AA – 2010-18 Ram 2500/3500 AAM 11.5” Rear Axle SRW & 2019-2022 Power Wagon
10404022AB – 2019+ Ram 2500/3500 AAM 11.5″ & 12″ Rear Axle SRW & 2023+ Power Wagon
