Dodge Front Differential Cover, 12 Bolt

Dodge Front Differential Cover, 12 Bolt
Available Options:

This PML cover is heavy duty, sand cast aluminum with a low profile for clearance. Fins on the lower part where the fluid collects aid in heat dissipation.
PML designed this cover as a bolt on replacement for 2014 and newer Dodge Ram 2500 and 2013 and newer RAM 3500 trucks.
However 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.

Because of many clearance issues with steering, u-bolts, and suspension, PML maintained a low profile with partial fins with this cover.
The PML cover is larger than the stock cover so please check your truck carefully to make sure you have space for a larger 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.
