Applications:

This rear end differential cover fits many Ford F150s, vans and SUVs with the 12 bolt for 9.75 differential. Some possible applications are:

• F150, 4.6, 5.0 or 5.4 engine, 2003 to 2019
• F150, 1997 to 2003, 5.4 engine

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

Note to Lightning owners: Ford Lightning 1999 to 2004 have a sway bar very close to the stock cover and there is no space for a larger aftermarket cover. Check your truck carefully for clearance.
