PML designed this cover as a bolt on replacement for:

  • 2014 and newer Ram 2500
  • 2013 and newer RAM 3500 trucks

Ram changed to this 12 bolt American Axle 9 1/4 inch 235mm front to improve the durability, steering and control, according to

This PML cover is heavy duty, sand cast aluminum. Fins on the lower part where the fluid collects aid in heat dissipation.

Because of many clearance issues with steering, u-bolts, and suspension, PML designed a cover as close to the shape and size of the stock cover as possible.

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.

There is a Safety Recall Notice for the front suspension on Ram 2500 and 3500 trucks. After any modification, the installer or mechanic must verify clearance. See also this thread on the Turbo Diesel Register Forum.

What Ships With the Cover?

PML ships new mounting bolts, fill hole plug and a magnetic drain plug with each cover.

Rear Differential Cover

PML makes a matching rear end cover for these Ram trucks. Please see the AAM 11.5" ring gear, 14 bolt cover or the AAM 10.5" ring gear, 14 bolt cover.


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.
