Always check your vehicle to verify differential and clearance. Configurations vary.
PML designed this cover for Ram trucks with the AAM 11.5 or 11.8 inch ring gear rear differential. Trucks which may be able to use this cover include:
- Ram 2500, 2003 to 2013 with the high output diesel, 5.9 diesel or 6.7 diesel, some have AAM 10.5 differential
- Ram 2500 Mega Cab, 2006 to 2013 with the 5.7 Hemi, 5.9 diesel, or 6.7 diesel, some have AAM 10.5 differential
- Ram 3500, 2003 to 2018, maybe 2019 and newer
- Some GM/Chevy Heavy Duty trucks, see note below
2019 and newer trucks: around 2019, Ram introduced the AAM 12 inch differential
that needs a different cover.
 
See
PML Part Number 11176 for the
similar AAM with a 12 inch ring gear.

- This bracket has been seen on 3500 trucks with the optional air bag leveling and 2014 and newer Ram 2500 trucks.
- The second picture shows bracket, sway and pan hard bars on a 2016 Ram 2500, this truck needs PML Part Number 11147
- The third picture shows a customer who wanted this 1 quart over stock cover and decided to remove some material from the outside of the PML cover and the bracket to make the bracket fit. PML does NOT recommend this. Customer also used a Hellwig sway bar for extra clearance.
- PML Part Number 11147 is designed to work with the bracket and clear the OEM pan hard and sway bars on most trucks. It holds 1/2 quart over stock.
2003 to 2013 Ram 2500: Some Ram trucks have the AAM 10.5 rear axle. 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. Frequently, 2003 to 2013 Ram 2500s with the V10, or standard output diesel, or the 5.7 Hemi (regular, quad or crew cab models) have the 10.5. You might have a sticker in the glove box or on the driver side door that states the differential specifications.
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.
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.

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.

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 below the level check hole. Optionally, PML drill and tap this boss with a 1/8 NPT hole for an aftermarket 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
