Dimensions: Click here for dimensions. The PML cover is 1 inch deeper than the 2003 stock cover.

This PML differential cover fits the American Axle Manufacturing (AAM) rear axle with 11.5 inch (292mm) ring gear.

PML designed this cover for these Dodge trucks:

Ram 2500, 2003 to 2013 with the high output diesel, 5.9 diesel or 6.7 diesel
Ram 2500 Mega Cab, 2006 to 2013 with the 5.7 Hemi, 5.9 diesel, or 6.7 diesel
Ram 3500, 2003 to 2016 (and some 2017 models)
Silverado or Sierra 2500HD 8.1 or diesel, 3500 or 3500HD with this AAM 11.5 rear: If you choose to use this cover, part number 10361, you have to bend the brake bracket located at 12 o'clock. PML part number 9511 fits the same differential and accommodates the brake bracket.

Ram 2500, 2003 to 2013: Some 2500s have the AAM 10.5 rear axle. Usually, Ram 2500s with the V10, or standard output diesel, or the 5.7 Hemi (regular, quad or crew cab models) have the 10.5. See our AAM 10.5 inch cover. The American Axle 10.5 cover is flat at the bottom while the 11.5 comes to a point. You might have a sticker in the glove box or on the driver's door that states the differential specifications.

2014 and newer Ram 2500 trucks With Sway and Pan Hard Bars: These Ram 2500 trucks have coil or air suspension with sway and pan hard bars close behind the rear cover. See PML cover part number 11147. If you truck is lifted, uses an aftermarket sway bar such as Helwig, or has spacers on the sway bar, this cover may work for you. See Installations for an examples.

2014 and newer Ram 3500 trucks have leaf suspension, with optional air suspension. This suspension does not have the sway and pan hard bars.

Some new trucks have an 11.8 inch ring gear. The cover does not change. Some common gear ratios for this American Manufacturing rear axle are 3.42 and 3.73.

Always check your truck to verify your differential and clearance.

Drain, Oil Fill, and Level Check
This differential 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.

Optional Machining for Temperature Sending Unit
This cover also has an undrilled boss for a temperature sensor. Please call to order if you would like the boss drilled and tapped. There is a $45 charge.

Front Cover for 4WD Trucks
PML also makes a cover for the front differentials on Dodge Ram trucks. On our front covers, PML keeps the profile close that of the stock cover to avoid interference with the steering, frame or suspension.
