    Original Performance Pack Equipment. Does your Mustang's factory equipped limited slip differential (LSD) leave you spinning your wheels? The stock LSD is fine for the daily driver and boulevard cruiser, but not the hard driving performance enthusiast. When you upgrade to a Ford Racing Limited Slip T2R Torsen Differential you will experience a monumental improvement in both traction and handling performance. This Ford Racing Torsen Differential is the same exact one that is found as standard equipment on Performance Pack GT Mustangs, making it ideal for performance applications.

    Full-Time Torque-Sensing, Torque-Biasing. Ford Racing's T-2R Torsen 8.8" differential uses a worm gear friction system that features full-time torque-sensing and torque-biasing for maximize performance. Torque Sensing keeps power going to the ground during changing traction conditions, while Torque Bias factors how much torque the differential can send to the wheels depending on the available traction. This Torsen design is far superior to standard limited-slip differentials making it perfect for street, auto-crossing, and road racing.

    Required Upgrade. This Ford Racing IRS Torsen Differential was specifically engineered for use with Ford Racing Super 8.8" IRS Gear and Pinion Sets, including 3.31, 3.55, 3.73, and 4.09 gear ratios. Sold separately. This Torsen Differential is not for use with 3.15 gears.

    Application. This Ford Racing 8.8" Limited Slip T2R Torsen Differential is designed to be a direct fit upgrade replacement for 2015 to 2018 V6, EcoBoost and GT Mustangs equipped with independent rear suspensions (IRS) and requires the use of 34 spline axles.

    Technical Note. 4-ounces of CM-19546-A1 friction modifier will be required on the initial fill.

    I have a ‘16 base GT with 3.15 rear, can I use the stock housing and install this diff and ford performance 3.73 gear?


    • This diff would allow you to run 3.73 gears with the stock housing yes.

    I have a GT with the base 3.31 gearing. Will this work with those gears? Is there anything else necessary in order for it to work?


    • This diff would work with the 3.31 gears and you would not need anything else for the install.

    Hi, is this better compared to the wavetrac differential?


    • The Ford Performance T2R Torsen Differential is the standard equipment on the Performance Pack Mustangs, so it will give great traction and handling. Since we do not offer the Wavetrac Differential, we cannot give an accurate comparison.

    will this fit a 2016 ecoboost 2.7 f150? i have a super 8.8 diff


    • No, unfortunately, the Ford Performance T2R Torsen Differential is specifically designed for Mustang fitment only and will not work with your 2016 F-150.

    I have a new 2017 Mustang v6 with the 3.1 gears. I want to upgrade to 3.73 gears. Besides the gears, what differential and swap kit do I need? Thanks.


    • You would need this Ford Performance T2R Torsen Differential to make the 3.73 gears work in your mustang as 3.73s are not compatible with your current differential .
