Stronger Than Stock. When upgrading the rear gears in your Mustang it's always a good idea to replace the wimpy stock differential cover with a super strong, light weight Aluminum Differential Cover for additional safety and peace of mind.

Finned Aluminum Reduces Heat. Constructed from light-weight cast aluminum the B&M Mustang 8.8" Differential Cover features a finned design that dissipates heat much faster than the factory unit to prolong the life of your ring and pinion gears.

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

Application. This Finned B&M Differential Cover is designed to fit the 1986-2014 Mustangs equipped with the 8.8" solid axle rear end, including the 2011-2014 V6, 1986-2014 GT, Bullitt, Mach 1, BOSS, Shelby GT500 and 1993-1998 SVT Cobra.

Hi Quality Part

Looks great and fits great. I like the bearing supports, deep cooling fins, and fill and drain plugs. The only surprise is the added fluid capacity - a LOT more fluid than stock to help cooling. Plan on ...

Would this cover fit while using a Fays2 style Watts-link? Specifically on a 2011 GT. Thanks.

  • Unfortunately we cannot guarantee fitment for this application. I would recommend contacting both manufacturers for measurements on these items to check fitment and compatibility.

How is clearance with the panhard bar on this? Specifically a 2008 GT with the Steeda adjustable bar.

  • See the clearance in my photo. I have a 2012 GT with LCA relo brackets and billet aluminum LCA from Steeda. I have barely any clearance but it works.

    Hi Quality Part

    Looks great and fits great. I like the bearing supports, deep cooling fins, and fill and drain plugs. The only surprise is the added fluid capacity - a LOT more fluid than stock to help cooling. Plan on 8 quarts to fill this beast. At $20/qt, that's $160 of 75W 140 synthetic gear oil to finish the job!

    Nice solid piece

    American muscle was great to deal with as always. Do a parts inventory before removing your stock cover! In my excitement to do the install I took off the stock pieces and prepped everything to go on, only to discover that B&M did not include the magnetic drain plug and the supplied washers were too big to fit into the machined holes in the cover. After I supplied my own hardware I will say its a beautiful piece and the bearing cap support bolts give me a little more piece of mind when hammering the throttle.

    Best Diff Cover Available

    I chose this cover for its features and great looks. It seemed to have the best combination of all the features of all the covers and this part did not disappoint. This cover was an exact fit and did not require any relocation of the panhard bar. The installation instructions were easy to follow and I was able to install the cover in about an hour in my driveway. The hardware in the kit is all stainless steel and high quality (it even has a magnetic drain plug). The only complaint that I have is that this beautiful part isn't as visible to the vehicles behind me like it would be on a lifted truck.

    Once again I order on Wed and have my parts by Fri! AM ships their stuff right away so it takes only two days to have my parts with free standard shipping and I'm in Boston! Cover is a nice quality piece and was described well Appreciate the Mach 1Reg discount too! Both my son and myself have used AM many times and will continue to do so in the future. - Jim C
