As a standard part of the 2015-2017 GT Performance Package, this differential will take your Pony to a whole new level regardless if you are using it on the road or pushing it on the track. Designed to fit 34-splie axles, this differential will support a solid rear-end or new Independent Rear Suspension (IRS) installation.

The highlight of the performance upgrade is that you'll see a significant increase in the torque performance of your 2015-2017 Mustang. Your Pony will enjoy full-time torque sensing & biasing while you push it during those heavy use times. Torque sensing will keep your engine power to the ground while going through a variety of traction situations, while torque bias will provide how much more torque this differential can send to your tires. Ford Performance also designs this differential to have limited slip, so it will transfer 100% of torque to each rear wheel simultaneously, allowing both wheels to put the power down on the ground for increased traction and a better overall driving experience.

Please Note: Installing this differential will require the use of 4-ounces of friction modifier with initial fill.

Product Questions

Will this work in the 8.8 in a 2016 F150?

Asked by: TWBO
Tried it and no, the 2016 F150 diff requires circlips on the inner end of the axle shaft to hold the axles in place. This Torsen diff does not support that. It will only work in the IRS diff.

Will this Diff + M4210B3 + M420988373A be all the hardware I need to let my garage change my gears from 3.31/LtdSlip to 3.73/Torsen? Or are additional parts required for my 2016 GT?
