Volume: 0.75 quarts over stock

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) or 11.8 inch (300mm) 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 2018, maybe 2019 and newer

2019 and newer trucks: We do not yet have any information on these model years. Let us know what you have: or 310-671-4345.

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: See PML cover part number 11147.

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.

Always check your truck to verify your differential and clearance.

There are several gear ratios for this differential, such as 3.42 and 3.73. The ratio does not change the ring gear size, 11.5 or 11.8 inches.

Drain, Oil Fill, Level Check and Hardware

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.

PML includes plugs, mounting bolts and a magnetic drain plug.

Optional Machining for Temperature Sending Unit

This cover has an undrilled boss for a temperature sensor below the level check hole. There is a $45 machining 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.

For the 14 bolt front cover: see PML's AAM 9.25" 14 bolt front differential cover

For the 12 bolt front cover (2013/2014 and newer trucks):, see PML's 12 bolt front differential cover

2014 Ram 2500 with Hellwig Sway Bar

Andrew Lowe installed PML covers and pan on his 2014 Project Bloodhound Ram 2500 4x4 6.7 Turbo Diesel. Because the truck is lifted and has a Helwig Sway Bar, Andrew used this larger PML cover instead of PML part number 11147. Andrew customized the covers with red powder coating.
