      Description

      Stronger Than Stock. When upgrading the rear gears in your Mustang it's also a good idea to replace the wimpy stock differential cover with a super strong, Aluminum Differential Cover for additional safety and peace of mind. This low profile Ford Racing Differential Cover features load bolts that provide additional support for the differential bearing caps which prevent side-to-side deflection.

      Cast Aluminum Construction. Made in the USA Ford Performance manufactures their Low Profile Differential Cover from 356T6 cast aluminum for superior strength and light-weight. The 356T6 aluminum construction helps to dissipate heat much quicker than the stock unit, which in turn helps to prolong the life of your Mustangs ring and pinion gears. As an added bonus the Cover has the "Ford Racing" logo engraved directly on it. 

      Direct Bolt-On Installation. Ford Performance designed their Differential Cover to be a direct bolt-on upgrade for your Mustangs factory differential cover. With the included gasket, bolts and washers this Cover can be installed in about an hours’ time.

      Recommended Upgrade. When changing your differential cover it is recommended to upgrade to fresh Royal Purple Synthetic Gear Oil. You will require 3 quarts of Gear Oil.

      Application. This Ford Racing Differential Cover is designed to fit the 1986-2014 Mustangs equipped with an 8.8" solid rear axle, including the 2011-2014 V6, 1986-2014 GT, Bullitt, Mach 1, 1993-1998 SVT Cobra, and 2007-2012 Shelby GT500 models.

      Application Note. This Ford Racing Differential Cover will not fit 1999-2004 SVT Cobras equipped with an Independent Rear Suspension (IRS), or 2013-2014 Shelby GT500 models.

        Very well made

        Very well made. Even though you really can’t see it under the car unless you put it on a rack. You know the quality is there. Took less than an hour to install. It’s a lot stronger than the stock flimsy piece. This is a must have when swapping gears.

        Nice finishing touch!

        This cover looks and fits great! I have 4:10 gears and a stock Panhard bar on my 2008 Mustang. The ring gear has room, but just. I doubt any larger ring gear would work. I was concerned about clearance to the Panhard bar, but it clears by about 1/4”. You will need to take loose one end of the Panhard bar to install it. But it looks great and makes for a nice finished look.....even if it isn’t seen by many.

        Great quality cover.

        I initially purchased a UPR cover, which was a very rough cast, and just poor quality in general. This cover is exactly what I had hoped.

        Nice addition to my 2012

        This is a pretty high quality cover that really accentuates the rear end. A bit pricey but a nice touch.

      5 Top Rated Questions

      How much fluid does does rear end take with this cover?

      • You will need 3 quarts of gear oil when using this Ford Performance Differential Cover.

      Helpful (2)

      Is that a fill and drain plug on the cover? I know that there is a fill plug on the other side of the diff from factory but hard to get at, so this would make it easier if it is. Also do you offer something to make getting the oil into the case easier?

      • The Ford Performance Differential Cover has a fill port on the upper passenger side of the cover, a drain on the lower passenger side, and two adjusters for the braces on both sides on the raised section. We do not offer anything that helps with filling the diff, however a section of tubing on the bottle can be used to help in filling the diff, or a fluid transfer hand pump.

      When installing this diff cover, can I use silicone instead of the gasket it comes with? I've heard the diff starts leaking quickly with the gasket. Thanks.

      • When installing the Ford Performance Differential Cover you can utilize the existing gasket, RTV silicone sealant, or a combination of the two. If using an RTV sealant, we recommend utilizing a RTV Black sealant such as that offered by Permatex, or equivalent.
