      Description

      GT500 Original Equipment. This Ford Racing Finned Differential Cover is the same exact one found as original equipment on the 2013 Shelby GT500 with the Track Pack option. Designed with cooling fins to reduce overall gear oil temperature to improve gear and bearing life, this Differential Cover features fittings for differential cooler pickup and return lines, as well as an oil temperature sensor.

      Finned Aluminum Reduces Heat. Constructed from light-weight cast aluminum the Ford Racing 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 Ford Racing 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.

        5 2008 GT - Fbmustang2008 Installation Time: Less than 1 Hour

        OEM part

        2008 GT/CS. Upgraded, should have done long ago, maybe the orginal differential would have lasted longer than 250,000 miles. The box included new longer bolts and all three plugs.

        5 2013 GT - MPD1055 Installation Time: Afternoon

        Great upgrade

        I also installed the BMR Panhard bar at the same time but it fits and looks great, and instead of using RTV silicone for the gasket i just got the LUBE LOCKER LLR-F880 diff gasket no mess and much easier and re-usable, I put the stock breather on the new cover and used the "Turkey baster style breather "AR3Z-4A058-B" that was part of a Ford TSB on the factory axle breather location.

        Great purchase

        The differential cover fits on great and is an amazing replacement for the old cover. Not only that but it also adds in a inserting plug and a drain plug which is helps for future maintenance.

        Nice Upgrade

        Had a leaky diff cover and decided to upgrade. Glad I did. Quality ford product. Functional, looks great. Came with the longer bolts needed due to the thickness of the cover. Make sure to pickup a gasket or silicone gasket maker.

        Excellent part....excellent service !!

        My Son told me about American Muscle, and swears by them for his '92 GT resto-mod project. I pulled the trigger on this sweet diff. Cover as a Christmas present 2 days ago. The price was lower than everyone else, and the part shipped within 8 hours of my order. These folks are fast, honest, and smart. They verified my fitment before charging me which nobody else has ever done for me. Well done AM ! You've earned a customer for life. Thank you, GR.

      Does it come with a axle vent plug? or does it use the stock axle vent as well.
