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

  • Bronco, within in line 6 cylinder 302, 351 engines, 1987 to 1996

  • Marauder, 2003 to 2004
  • Mountaineer, 1997 and newer
  • Mustang, 1987-1995 (1996 to 2011 appear to have the same differential)
  • Navigator
  • Ranger, 4.0 engine, 1989 to 2012
  • Mazda B4000, B2300

Always check to verify differential and available space. Configurations vary.

Some models may have the smaller Ford 7.5 differential or the larger For 9.75 differential. Check the dimensions, number of bolts, and shape of the stock cover.

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

PML makes two designs. This cover has a large, round shape and straight fins. The other PML Ford 8.8 cover has more clearance and patterned fins.

This Ford differential cover is designed for non-IRS, rear differential on Ford vehicles. Some 4WD F–150 trucks have the 8.8 ring gear differential in the front but enough room for a larger than stock differential 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.

Number of Bolts: 10 bolts

Volume: 0.6 quarts over stock

This PML differential cover is designed for rear Ford 8.8 inch ring gear applications with the 10 bolt stock cover.

  • Hardware included

PML makes two covers for the Ford 8.8 inch ring gear differential. PML Part Number 9519 has a pattern fin design and more clearance for pan hard and sway bars, gas tanks, spare tires and similar.

Drain, Fill, Level Check and Optional Temperature Sensor Machining

PML diff cover for Ford 8.8 drain hole

This PML cover includes a drain on the bottom of the cover and fill holes on the side and the top

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.

For a temperature sending unit, PML can machine the boss under the level check. This location is at about 4 o'clock. This is optional and there is a machining charge.
