Benefits:

Profile similar to stock cover for clearance on Ram 2500, 3500 trucks
Drain hole and magnetic drian plug for easier servicing and following 15K oil change interval recommended by Ram
Extra capacity
Fins for heat dissipation
Heavy duty sand cast aluminum construction
Machined gasket surface for a secure seal
Oil fill/level check hole and plug at same location as on stock cover

Applications

PML designed this front differential cover for:

2003 to 2013 Ram 2500 (2013 is transition year, verify stock cover has 14 bolts)
2003 to 2012 Ram 3500
2006 to 2008 Ram 1500 Mega Cab

Always check your truck to verify differential and clearance.

2013 and newer Ram 3500 and 2014 and newer Ram 2500 have an updated AAM 9.25 differential with a 12 bolt cover. See PML part number 11136.

The PML front rear differential covers and transmission pan look great in custom powder coat. The covers started in the natural as-cast finish and Kevin had them powder coated with the rest of the suspension to a custom teal blue.

Kevin's 2012 Ram Megacab is a 2019 SEMA Show truck. The truck is also known as the "Alberta Adventurer" and features an 8 inch lift, BDS long arms, and American Force wheels.

2010 Ram 3500 SRW Mega Cab

Dave installed this PML 14 bolt front differential cover on his 2010 Ram 3500 Mega Cab. He reported no issues with the suspension and he did not cut off the end of the u-Bolt. When on a inclined and wheels at full left, he still had clearance.

2010 Ram 2500 HD Crew Cab

The pictures below show this PML cover installed on a 2010 Ram HD pickup. The truck has a 3" level kit and all Carli components. The clearance is very tight when the wheel is cycled to the left but makes no contact. Our thanks to Richie's Truck & Auto for installing a PML cover and sharing the pictures.

2008 Ram 2500 Quad Cab 6.7 Diesel

Larry installed this cover on his 2008 Ram 2500. He has a the U-bolt as shown in the first image. He serviced his differential at the same time he replaced the cover. He wanted a custom look, so he spray painted his cover a shiny red.

2007 Ram 2500 Mega Cab

Larry installed this front axle PML differential cover on his 2007.5 Dodge Ram 2500 Mega Cab 4x4 with the 6.7L Cummins diesel. He noted the clearance with the steering at the stops on the left and right at ½ an inch minimum. In the forward position, the clearance with the stock cover is 2 inches and 1½ inches with the PML cover.

These images show (left to right) Ram 2500 Mega cab stock cover, PML cover installed with wheels straight, PML cover with wheels at the right stop, and PML cover with wheels at the left stop.

Specifications

Drain, Fill/Level Check and Optional Machining for a Temperature Sending Unit

Click on image to view larger.

Drain hole is on the bottom of the cover. A magnetic drain plug is included. A drain on the differential cover makes for easier servicing of the differential.

Level check/fill hole is on the side at the 3 o clock position. The bottom of the Level/fill hole is at the same location as the OEM cover level check fill hole relative to the differential center line. This means that you fill and check the fluid level the same way with the OEM cover as with the PML cover.

For people who have an aftermarket gage monitoring the differential fluid temperature, this cover has a location that can be machined for the sending unit. The area about the 4 o clock position can be drilled and tapped for a 1/8 NPT hole for the sending unit. Optionally, PML can machine the hole and there is a custom machining charge. Select this option before clicking ADD TO CART. Verify the thread specification of your aftermarket temperature gage sending unit before ordering. Customer must select this option. By default, the 1/8 NPT is NOT machined.

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 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.

In first picture, PML cover is on the left and the stock cover from a 2007 Ram 2500 Mega cab is on the right.
In the second picture, PML cover is next to a stock 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.

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.

Rear Differential Cover

PML makes a matching rear end cover for these Ram trucks. Most common rear differential covers are AAM 11.5" ring gear, 14 bolt cover, (click here) or the AAM 10.5" ring gear, 14 bolt cover (click here).

Gasket

PML recommends RTV. 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.

Optional Temperature Sending Unit Machining

Optionally, PML can drill and tap for a temperature sending unit at the 4 o clock position on the side of the cover. This would be a 1/8 NPT hole and would include a plug.
