PML makes two different covers for the Ford 8.8 differential. One has a straight fin design and one has patterned fins. They are also different sizes so check the dimensions and your vehicle for clearance.


Both these rear differential 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.

These differential covers feature a drain hole, a fill hole, a level check hole, and an un-machined temperature sensor boss. Some Ford differentials have a factory fill location on the driveshaft side of the third member. Newer vehicles do not and can use the fill hole on the differential cover. PML can machine the boss for a temperature sensor. There is a machining charge and this option needs to be ordered over the phone.


This rear end differential cover fits many Ford trucks and SUVs. Vehicle configurations vary so check yours carefully. Some common applications are:

  • Bronco, within in-line 6 302, 351 engines, 1987-1996
  • Crown Vics, 1982-2005 (may also have 7½ differential)
  • Explorer, 1991 and newer
  • F150, 1980 and newer (may also have 9¾ differential)
  • E150, 1992 and newer
  • Lighting, 1993-1995
  • Marauder, 2003-2004
  • Mountaineer, 1997 and newer
  • Mustang, 1987-1995 (1996 to 2011 appear to have the same differential)
  • Navigator (may also have Ford 7½ differentials)
  • Ranger, 4.0 engine, 1989 and newer (other engine sizes, please check the PML Ford 7.5 differential cover)
  • Mazda B4000, B2300 (may have other differentials)

Some models do not have clearance for a larger differential cover. Always check if you have clearance before ordering.

Some models may have the smaller Ford 7.5 differential, which is more rounder in shape and shorter (vertically). Other models have have the larger For 9.75 differential, which has a different shape and has 12 bolts. The Ford 8.8 stock cover is about 11 inches vertically and the 7.5 inch is about 9.75 inches vertically.

Check out our Ford 7.5 diff covers for pictures and more information if you have the smaller differential.

Check out our Ford 9.75 diff covers for pictures and more information if you have the larger differential.

PML makes two designs for the Ford 8.8 inch rear end to accommodate a variety of preferences and vehicles. Click here for the straight fin design or click here for the patterned fin design.

This Ford differential cover is designed for non-IRS, REAR differential on Ford vehicles. Some 4WD F150 trucks have the 8.8 ring gear differential in the front but on the trucks we have seen there is not enough room for this cover. For vehicles with IRS, the linkage bolts on to the cover and PML differential covers are not compatible.

Note to Expedition owners: a larger cover may be too deep to clear the track bar that runs behind the differential cover. Using the dimensions, please check your vehicle for clearance before purchasing.
