High bias Torsen T2R torque-biasing differential is a full-time torque-biasing system, not just a limited slip differential. The Torsen differential has a unique helical-gear design with no clutch plates or preload springs. It provides continuous, uninterrupted torque output, torque biasing, and differentiation in one integral unit. The Torsen greatly improves traction because it is continuously and instantly responding to torque feedback from the tires, sending more torque to the tire with the most traction.

This unit only fits 2015 and newer Mustangs with 3.31:1 and numerically higher gear ratios. Code-named "Peregrine", this Torsen unit is an enhanced, high-torque capacity design with 6 planet gear sets, an improvement on the OEM Ford-offered Torsen models. The Peregrine unit has improved strength and even greater gear life, which is especially beneficial for open-tracked Mustangs.

This model only fits the 2015+ Mustang IRS 34-spline axles, and will NOT fit solid axle versions of the Super 8.8" axle, such as the F-150 truck.

Torque Bias ratio
  • Drive   3:1
  • Coast   2:1

The 3:1 Drive TBR of the Torsen T2R means this differential is capable of delivering up to three times as much torque to the tire with better traction than is delivered to the tire with the least available traction. Excellent for all driving situations; street, autocrossing, and road course.

Torsen differentials have NO clutches or preload springs.

Ford equipped several Mustangs with a Torsen differential as original equipment:
  • FR500S, Boss 302R, Boss 302S
  • Boss 302 (optional)
  • Boss 302 Laguna Seca
  • 2013-14 Mustang with the OEM Track Pack option
  • Torsen differentials provide a very high resistance to wheel spin during hard acceleration, yet still allow easy turn-in at corner entry.
  • Inside rear tire spin at corner exit is held in check because the Torsen distributes more torque to where it can best be used; the outside tire.
  • High TBR of 3:1 is great for street, autocrossing, and open-tracking.
  • The Torsen's unique torque distribution ability creates an understeer-canceling yaw effect that helps the car drive through the corner, increasing the lateral acceleration potential.
  • Cornering traction is maximized by reducing the understeer typically caused by preloaded clutch-type differentials.
  • Torsen differentials have no clutches to wear out.
  • High torque bias ratio of 3:1 under power, 2:1 when coasting
  • 6 planet gear sets
  • Helical-gear torque-sensing design; no clutches or preload springs
  • No unusual gear oil requirements
  • Friction modifier is NOT required
  • Available only for the stock 34-spline IRS axles
  • No clutches or preload springs
  • NOT included: Ring gear, bearings, seals, oil, etc.
Fits
  • 2015+ S550 Mustang & Shelby GT350 Super 8.8" IRS
  • 3.31:1 and numerically higher gear ratios
  • 34-spline IRS axles
Does NOT fit
  • Solid-axle Super 8.8" axle, such as in the F-150 truck
  • Standard 8.8" rear ends, IRS or solid-axle
