This American Axle rear end differential cover fits some 2003 and newer Dodge Ram 2500 and 3500. These models may have a 10.5-inch or an 11.5-inch ring gear. (See our AAM 11.5, 14 Bolt for Dodge differential cover if you have an 11.5-inch ring gear - click here.) Check the identification sticker in your glove box or on your driver's door to determine which differential you have.

This cover has oil fill, level check, and drain holes to make it easy to follow the 15K oil change interval that Dodge specifies for the AAM axles used in 2003 and newer Ram 2500 & 3500 trucks.

This diff cover also has an undrilled boss for a temperature sensor. Please call to order if you would like the boss drilled and tapped.

PML also makes a cover for the front differential on these Dodge Ram trucks. Click here for information on the AAM 9¼" ring gear, 14 bolt differential cover.
