This cover is a bolt on replacement for the stock cover on the American Axle Manufacturing (AAM) 9 1/4 inch 235mm ring gear differential used in Dodge Ram trucks.

2013 Ram 3500 and 2014 and newer Ram 2500 and 3500 have a new front end with a football shaped cover. See PML Part Number 11136 for that cover.

Always check your truck to verify differential and clearance.

This differential cover features a low profile for clearance and oil fill/level check and drain holes to make it easy to follow the 15K oil change interval. Extra capacity, fins, and aluminum construction aid in heat dissipation to keep fluid cool.

Why a Low Profile Cover?

Because of many clearance issues with steering, u-bolts, and suspension, PML maintained a low profile with partial fins with this cover.

Starting in about 2008, Dodge added a u-bolt to the front end design that would contact larger aftermarket covers when at the limit of the steering. This u-bolt was retrofitted on early year trucks during service visits. The suspension on Megacabs would also contact a larger cover when the truck was loaded. To avoid these problems, PML designed this cover. The PML cover follows the contour of the stock cover to maintain clearance. The fin-free left side prevents interference with the u-bolt. This PML cover is on the left and the stock differential cover from a 2007 Ram 2500 Mega cab is on the right. The PML cover is still larger than the stock cover so please check your truck carefully to make sure you have space for a larger cover. Reference the dimensions in the above link.


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. This PML cover is compatible with Mopar gasket part number 5086682AA.
