Ford Racing Torsen???� Differential Rear

These Ford Racing Torsen differentials use a worm gear friction system that will not wear out like conventional clutch-type positive traction differentials. These differentials ensure your engine's power is transferred to the wheels with the maximum traction. The unique torque-sensing ability of the Torsen design, and the smooth engagement of Torsen-style limed slip differentials, make them the perfect choice for your street, strip, or off-road vehicle.
