AFE Power's rear differential covers for Dodge and GM trucks

aFe Power's differential coverExperience performance engineering with Advanced Flow Engineering/aFe Power’s rear differential covers  for 03-10 Dodge Ram Cummins and 01-10 GM Duramax trucks part numbers 46-70011 (black fins) and 46-70012 (machined fins). The cover boosts lube capacity by holding 5 quarts compared to the factory cover’s capacity of 4 quarts.  Magnetic plugs ensure maximum rear end protection, and internal and external fins transfer heat from the fluid to the outside air, improving cooling.

Maintenance is simplified through a large oil level site glass with a calibration plug set to factory levels that eliminates overfilling. Constructed from durable die-cast T356-T6 aluminum, the cover provides a high level of strength. The cover also features a wrinkle black powder coating.
