PML designed this differential cover for the Dana 44A. The Dana 44A is also called Dana 226, Dana 44 SRT8, and Dana Super 44. This differential is found on the rear of some WK, WJ and XK Jeeps, such as SRT8 models of Grand Cherokee.
The shape and bolt hole pattern of the cover for a Dana 44A is not the same as the regular Dana 44. Be sure to verify that the differential is a 44A before ordering.
- Designed to clear sway bar on Grand Cherokee SRT8 Jeeps
- Extra capacity
- Fins to aid in heat dissipation
- Heavy duty sand cast aluminum construction
- Drain hole and magnetic drain plug
- Level check/oil fill hole
- Thick, machined gasket flange for a secure seal
- Optionally can be machined for a temperature sensor
Installation Note: Once installed the fins clear the sway bar on 2006 to 2010 Grand Cherokee SRT8 Jeeps. However, it is necessary to temporarily drop the sway bar to remove the stock cover and install the PML cover.
The Dana 44A 226 or Dana Super 44 is found on the rear of some WK, WJ and XK Jeeps. This cover usually fits:
- Jeep Grand Cherokee SRT8 2006 to 2010
- Jeep Commander 2006 (and probably 2007 to 2010) with the Dana 44A/226 differential (usually the 2WD models, Commander Limited and Overland models have an option of the 44A/226 differential)
- Jeep Grand Cherokee WJ 4.7 with aluminum housing, 1999 to 2004, can use this cover when a spacer is added to the sway bar or if the Jeep is lifted — without additional space this cover hits the sway bar on 1999 to 2004 models
- Jeep Grand Cherokee ZJ, 1996 to 1998, may have the Dana 44A/226 rear axle and be able to use this cover, especially ZJs with the 5.9 or 5.2 V8. ZJs also used regular Dana 44 and the Dana 35 differentials
Check your differential for size, shape, number of bolts and clearance before ordering. Jeep used variety of Dana differentials. Click to view a dimensions in a separate window and keep in mind that there is a restocking fee of 20% for returns.
This rear end cover may fit other SRT8 vehicles or other Jeeps.
PML developed this differential cover in response to many phone and email requests. We knew there was a problem when we got a call from an owner that the paint was peeling off the stock cover because the fluid temperatures were so high.
Thank you to the many Jeep Grand Cherokee SRT8 owners who provided images, measurements, and suggestions during the design and development of the cover.
Some installations temporarily take the sway bar off, like surfrman's (below), other people lift their vehicles so no weight rests on the tires and install with the sway bar in place. Installer should verify installation and fitment based on the individual vehicle.
These folks have emailed us pictures of their installation of the cover on their vehicles:

2000 Grand Cherokee WJ
Generally, this PML differential cover will not fit 1999 to 2004 Grand Cherokees because there is not enough clearance between the sway bar and the rear axle cover. PML customers have worked around this with a lift kit or added spacers.
Phil has a 2000 Grand Cherokee WJ with a Dana 44 Super. He added spacers to his Addco aftermarket sway bar and called to report that this PML cover fit beautifully. Here is what Phil did:
- Confirmed which differential he had by calling his dealer with his VIN before ordering the PML cover
- Checked the clearance between the PML cover and the sway bar
- Bought a 3/4 inch 6061 aluminum bar on Ebay (washers do not make good spacers, see note below pictures)
- Cut the bar to make his spacers for the sway bar
- 3/4 inch raised the Addco sway bar to avoid contact with the larger PML cover and 1/2 inch probably would be fine with stock sway bars
- Used case hardened 2 inch bolts with spacers in place of 1 inch bolts
- Addco sway bar with spacers clears larger PML cover
- The gas tank did not have any clearance issues
- Other than the spacers, the cover installation was straight forward, without any other modifications
Our thanks to Phil for his feedback and pictures.
Note from Phil about the spacer: Washers do not make good spacers. Washers will give the clamp the expected rise but do not secure the bushing to the base so it will move around inside the clamp and over time most likely cause the bolts to snap but a solid plate spacer supports both the clamp as well as the bushing. Also if you measure and drill your holes exactly, which in his case was 2 3/4 inches center to center, and only drill them big enough for your bolts to comfortably fit thru, the spacer itself will provide added lateral strength to your installation.
1998 Jeep Grand Cherokee ZJ
Ramon installed this PML Super Dana 44 cover on the rear and PML Dana 30 on the front of his 1998 Jeep Grand Cherokee 5.9L. His ZJ is lifted and had extra clearance, which allowed for the install of the rear cover.

Bolt Hole Pattern
This image shows the bolt pattern from the stock rear cover of a 1996 Grand Cherokee compared to this PML differential cover. Note that the bolt patterns match.
This image also includes the distances between the bolt holes so you can use this to check if the bolt pattern on your stock cover matches.
Many thanks to our customer Chris who created this drawing.
Front Differential Cover for 4WD Vehicles
Some Jeeps have a Dana 30 on the front and can use PML part number 5058.
For Jeeps where the stock front differential cover connects to the suspension, such as the Grand Cherokee SRT8, PML does not make a front cover.
Optional Machining for Temperature Sending Unit
This cover has an undrilled boss for an aftermarket temperature sensor sending unit on the side at the 4 o clock position. There is a machining charge for PML to drill and tap the hole.
Drain and Fill/Level Check
This cover has a fill/level check hole on the side at the same level as the stock cover.
A drain hole on the bottom makes for easier maintenance.
A plug for the fill/level check hole and a magnetic drain plug are included.
