04-17 F-150 4x4 8.8inch Front Axle Limited Slip Torsen Differentials Ford Racing M-4204-F150LS

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.
