Description
Ford Performance Torsen Differential — Mustang Super 8.8″ IRS (2015–2024+)
Put real, usable traction to the ground with the Ford Performance Torsen limited-slip differential, a genuine factory-grade upgrade for the S550 and S650 Mustang platforms. This is the same Torsen(R) T2R differential fitted as standard on the 2015–2020 Mustang GT Performance Pack, delivering the full-time torque-sensing, torque-biasing performance that makes a measurable difference in both road driving and track use.
Unlike a clutch-type limited-slip diff, a Torsen unit works mechanically and continuously, redirecting torque to the wheel with the most grip without any driver input, clutch packs to wear, or on/off locking behaviour. The result is smoother, more predictable power delivery through corners and off the line, with genuinely increased traction whenever you need it.
This differential is engineered to fit the Super 8.8″ rear end with 3.31, 3.55, 3.73, or 4.09 ratio gear sets, and is built for 34-spline axles, making it compatible with both a solid rear axle setup and Independent Rear Suspension (IRS) installations.

- Requires 3.31, 3.55, 3.73, or 4.09 ratio gears
