FORD 8.8" C-Clip 31 Spline TorqueWorm Limited Slip Differential

The Speedmaster™ TorqueWorm¨ is a helical-gear style performance differential that maximizes wheel traction and enhances driving and handling characteristics. It combines the smooth operation of a limited-slip differential, with the strength of a fully-machined, forged steel case. Based off of throttle input, you are in control of how much traction is applied, which is great for situations where finesse is as important as extreme traction. Operation of the TorqueWorm is smooth, quiet and automatic. The unit will engage without any driver knowledge or action required. It also has no wearable parts and requires no maintenance, meaning less time in the garage and more on the road.
