        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.

        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.

          Quality part

          It was time to change the fluid - and I just couldn't put that stamped piece back on. I like the fact that now I have a drain plug to make next time much easier. I used the supplied gasket with no rtv - and it has held up with no leaks. Do yourself a favor and drop the panhard bar

          Ford Racing differential cover

          Actually ordered the BandM cover first with large cooling fins on outside, but would not work because it hit the rear sway bar on my 2004 Saleen when I test fitted. American Muscle was excellent with the return and shipped this one instead, and it works perfect. No leaks at all using just the gasket with no sealant as the manufacturer recommends. I am very happy!

          Outstanding Item

          I had to replace my rear end pinion seal and took the chance to change out the gears and the differential cover. This item was well worth the money and makes it a lot easier to drain and fill the rear differential in the future. Would highly recommend this item.

          Definite upgrade

          I replaced my stock cover with this Ford Performance cover while getting a rear axle shaft leak repaired. It's not a part you can see unless you are underneath the vehicle but it's a definite upgrade over the stock cover. This cover dissipates heat better and that alone was why I went with this cover. Definitely recommend.

          Why Not?

          Working on a Project SN95 Convertible (Oct 94, 95 Model year) and found a 8.8 rear axle to swap out the 7.5 stock. Got it home ($220.00) and opened the pumpkin. The Stock 3.27:1 and TracLoc was in great condition but the diff cover looked horribly like a peanut butter can lid so it was in need to go. I would like to have 3.73:1 but I am use to 2.73:1 so this is already and upgrade. I decided on this Girdle because in concert with the new axle, FMS Aluminum driveshaft, and SVE control arms I can now reach 400 rwhp without worries. After watching the short video (not the one on this site, very not useful) I followed what they suggested and it maybe took me 15 minutes at best. Looks great and now when the oil guy at my shop services my car, he can cry in his Chevy all the way home. Got to build the foundation guys and gals first. Too many people want to get under the hood and increase the HP over making sure the foundation can hold it all first. Do the math, plan it out, get the right parts, then blow them away.
