PML designed this cover for these 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, may have AAM 10.5 check shape
- Ram 3500, 2003 to 2018, maybe 2019 and newer
- Some GM/Chevy Heavy Duty trucks, see note below
Always check your vehicle to verify differential and clearance. Configurations vary.
2019 and newer trucks: These trucks may have the similar AAM 12 inch. Please see PML Project, Part Number 11176.
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 the top of the cover. 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 side 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.
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.
Our customers have installed this PML differential cover on many Ram 2500 and 3500 trucks.

PML includes plugs, mounting bolts and a magnetic drain plug.
Optional Machining for Temperature Sending Unit

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
Inside of Cover
This cover follows the same general curved profile as the stock cover.
