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? 1 answer

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.

Will this clear whiteline sway bar and whiteline panhard bar? 1 answer

The Ford Performance Differential Cover will clear with your Whiteline Panhard Bar and Sway Bars.

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. 1 answer

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.

Helpful (0)

Will this cover clear all aftermarket panhard bars and sway bars? Even on lowered cars? 1 answer

This cover will clear after market sway bars, panhard bars, and the car being lowered yes!

Well manufactured diff cover

It’s great that this kit has everything short of diff fluid to install. It contains the cover, necessary bolts, washers, and high quality gasket. I was going to use RTV but the gasket looked good enough for my application and hasn’t leaked.
