Dodge AAM 9.25" Differential Cover (12 Bolt)

Heavy-Duty Diff Cover for 2003–2020 Dodge AAM 9.25" Front Axles

This is our no-nonsense, heavy-duty differential cover for the Dodge AAM 9.25" front axle found on 2003–2020 Dodge Ram 2500 and 3500 trucks. Starting in 2014, these axles use a 12-bolt cover. If you have a 2013 model, double check—some used 14-bolt covers instead. Anything 2012 or earlier will use the 14-bolt version.

The cover is built from a single piece of 3/8" plate steel, bent in 8 places and welded to a 1/2" thick machined ring. All seams are fully welded inside and out. The fill plug has a 1" ID for easy filling and checking fluid levels. Ships as raw steel and includes 12-point bolts with washers.
