**Cutting and welding of the rear end housing is REQUIRED to complete this installation! Not recommended for novice mechanics!**

If you're like us and drag race your 05-14 GT or GT500 there's a good possibility you're going to break something. Our first trip to the track ended up with a burnt differential and our 2nd trip yielded us a snapped axle. So we've packaged up something specifically for our hardcore race customers just like what we installed in our 2013 GT500. Since we did the upgrade we've gone as quick as 9.39@147mph on slicks and haven't had any rear end issues since.

Our upgrade kit consists of Moser 31 spline axles, 9" axle ends, new bearings and a Ford Racing limited slip differential with carbon discs. All machining on the axles is already included and the ABS rings are pre-installed before the package ships.

Features:
(1) A2M00 31 spline Axles (pair)
(1) 8010 Press in or 8000 Screw in studs (choose from drop down)
(1) BPBB Axle Bearing kit
(1) SB12 Carrier Bearing and Race Kit
(1) 9A51 ABS rings (pair)
(1) 9A15 Machining for the ABS rings to be installed
(1) 7705 9" housing ends
(1) 913A561 Eaton Tru-Trac 31 spline Differential

NOTE: 2013-2014 GT500 customers will require the use of the 2013-2014 GT500 pinion bearing if you are adding this kit to the stock rear end housing. The pinion bearing can be added to the order by selecting it from the drop down. Also, 2013-2014 GT500 customers will need to use 05-2014 Mustang GT/07-2012 GT500 rear caliper brackets, rotors and backing plates. OEM caliper brackets will not work without modifications.Learn More
