PML makes two different covers for Ford trucks and SUVs. One has a straight fin design and is about 5 inches tall. The other has a patterned fin design and is about 3½ inches tall.

Both of these PML rear diff covers add capacity to help lower the differential fluid temperature. Thick walls and gasket flanges add strength to the differential housing and provide a uniform clamping force on the gasket surface for a secure seal.

PML designed the patterned fin cover for newer Ford trucks and SUVs that have less clearance due to cross frame members or spare tires. Please check the clearance on your vehicle before ordering.


This rear end differential cover fits many Ford trucks and SUVs. Some common applications for this 12 bolt Ford 9¾ differential are:

  • F150, 4.6, 5.0 or 5.4 engine, 2003 to 2017 (some 2015 and newer models have new Super 8.8 10 bolt cover)
  • F150, 1997-2003, 5.4 engine (other engine sizes from 1997-2003, please see PML Ford 8.8 diff cover)
  • Navigator, 1995-2006 can use this cover or the Ford 8.8 diff cover so check before ordering
  • Expedition, 1997-2002, 5.4 engine (check carefully for clearance)

Configurations vary. Always check the vehicle to verify the differential and clearance for a larger cover. Some vehicles may have a 10 bolt, Ford 8.8 or Ford Super 8.8 .

Note to Lightning owners: Ford Lightning 1999-2004 have a sway bar very close to the stock cover. Several Lightning owners have told us our covers will not fit because of that. Check your truck carefully for clearance.

Drain, Fill, Level Check, Temperature Sending Unit

These PML differential covers have a drain hole on the bottom and include a magnetic drain plug.

There is a fill hole on top.

On the vehicles this cover was designed for there is a plug on the driveshaft side of the differential for level check (this can also be used for filling).

A boss on the differential cover can be machined for a temperature sending unit. PML has machine shop and charges $45 per hole.
