A plate-type differential designed to operate with no pre-load, thus reducing friction that consumes horsepower. Removes torque-steer found in conventional diffs, and reduces understeer, enabling a neutral-steering car. X enables it to load up during the acceleration phase of the corner offering maximum grip.
Accepts normal LSD final drive sets and 10-spline diff output shafts.
Manufactured in the U.K. by Quaife.
