PML designed this cover as heavy duty, bolt on replacement for the front differential cover on 2014 and newer Ram 2500 and 2013 and newer Ram 3500 trucks. Ram re–introduced Central Axle Disconnect (CAD) starting with 2013/2014 model trucks to improve gas mileage.
- Drain and magnetic drain plug included
- Heavy duty, sand cast aluminum construction
- Fins on the lower part where the fluid collects aid in heat dissipation
- Profile close to stock cover to avoid clearance issues with steering, u-bolts, and suspension
- Machined gasket surface for a secure seal
- New mounting bolts included with cover
We have one of these covers in the polish finish on SPECIAL.
PML designed this 12 bolt cover for the AAM 9.25 front differential on:
- 2014 and newer Ram 2500 trucks
- 2013 and newer RAM 3500 trucks
Configurations vary so always check your truck to make sure you have clearance for any larger aftermarket cover. Trucks with the factory air ride suspension may have less clearance.
Ram changed to this 12 bolt American Axle 9 1/4 inch 235mm front to improve the durability, steering and control, according to FourWheeler.com. These new front axles have central axle disconnect.
We have heard that there is a Safety Recall Notice from the NHTSA for the front suspension on Ram 2500 and 3500 trucks. After any modification, the installer or mechanic must verify clearance. See this thread on the Turbo Diesel Register Forum.

2017 Ram 2500 Laramie 4x4 Diesel
Marion purchased PML front and rear covers for his 2017 Ram 2500HD 6.7 L Cummins Laramie. Our thanks to him for sharing pictures and comments from his installation.
He was not able to install the PML rear differential cover with the sway bar in place. He unscrewed four bolts and the sway bar lowered. He purchased this rear cover in the bare metal as-cast finish and found that touching it with oily hands made it look dirty quickly. So he painted the rear cover all black and purchased the front cover in the PML black powder coat finish. For fluid, Marion added 4 1/2 quarts of 75W 90 Synthetic Anti-Slippery Fluid for the rear.
He loves the look and the easiness of replacing the fluid wtih the PML covers.

Corey installed his cover and matching PML rear cover, Part Number 10361, on his 2014 Ram 3500 Tradesman Crew Cab Short Bed, SRW, 6.7 Diesel, G5 truck. On CumminsForum.com, he posted:
[I]nstalled my PML covers today. Probably should have just put the rear on and forgone the front one but they look good together. The front was a tad harder, took a allen wrench and ground about half an inch off of the short end and it would fit under the front bar that goes across the front top of the diff cover ( had to come in from the top). Other then that it was pretty painless.
Both are thick guys, thought quality was really good.
Our thanks to Corey for sharing his comments and pictures.

What Ships With the Cover?
PML ships new mounting bolts, fill hole plug and a magnetic drain plug with each cover.
Image at right shows the polish finish cover and what is in the box. Except for the cover, the content is the same for all finishes. Click on image to view larger.
Rear Differential Cover
PML makes a corresponding rear end cover for these Ram trucks. See:
- PML Part Number 11147 for 2014 and up Ram 2500 Trucks with the AAM 11 1/2" ring gear, 14 bolt
- PML Part Number 10361 for Ram 3500 trucks with the AAM 11 1/2" ring gear, 14 bolt
- PMl Part Number 10302 for trucks with the AAM 10.5" ring gear, 14 bolt
PML recommends RTV gasket material. RTV is a type of silicon rubber and it comes in a tube. There are several brands, such as Permatex, and these are readily available at automotive stores like Pep Boys and AutoZone.
Some people use the reusable factory gasket. Please make sure the gasket is clean and free of any nicks. If there is a nick in the gasket, that is where you'll get a leak.
Optional Temperature Sending Unit Machining
This part has an undrilled boss for an aftermarket temperature sensor.
Optionally, PML can drill and tap for a temperature sending unit at the 8 o clock position on the passenger side of the cover. This would be a 1/8 NPT hole and would include a plug.
This shows the inside of the PML cover. The shape generally follows the shape of the stock cover.
The fill/level check hole is at the same location on the PML cover as on the stock cover.
