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

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.
