This kit fits 8.8" rear ends and includes everything you need to swap out or upgrade your stock gears.

Royal Purple Max-Gear Gear Oil
This Royal Purple gear oil is an ultra-tough automotive gear oil. It’s designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.

Ford Racing Friction Modifier
This friction modifier is a specially formulated additive to provide smooth operation of clutch-type limited-slip differentials. 1 bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

- Fits 2010-2014 Mustang w/ 8.8" Rear End

4 Stars   3:55 Gears
By on 4/21/2015
The 3:55 gears are the perfect option. Really gets the car in the power band right away but still has great freeway manners. I am at 2400 rpms at 80 mph. Its a different car and the way it should have been.

Yes, I would recommend this item to a friend!

5 Stars   Just what my Mustang needed!
By on 5/7/2015
Due to some serious medical complications my docs tell me not to drive a car with a manual tranny anymore so my 2014 Mustang GT had to have an auto, and I could not find one with anything other than the 3.15 rear end. I ordered this kit and had a Ford dealer install it so as to protect my warranty. This is a perfect fit for my Mustang! There seems to be less of a "hole" when I start out from a dead stop. Acceleration is more lively and with the select shift I can actually get farther faster than friends with a manual transmission and the 3.73 rear. My local dealer was reasonable in what they charged as well. Shipping was fast, the car was in and out of the dealer in six hours, and I have a big grin on my face when I drive this now. This should be the rear gear in all automatic transmission Mustangs.
Highly recommended!
