Wilwood Rear Superlite 4R/MC4 Kit for Currie Pro-Tour Unit-Bearing Axles, Black 12.88-Inch Brakes

This Currie Pro-Tour rear conversion uses black Superlite 4R service calipers and separate MC4 parking units. The 12.88-inch slotted rotors and hats fit the specified unit-bearing floating axle rather than a generic vehicle rear end. Disc brake system design and manufacturing are Wilwood Engineering’s focus. Bill Wood founded the Camarillo, California company in 1977; its range spans brake rotors, master cylinders, calipers, fittings, valves and brake lines for motorsport, specialized and street-performance applications. The choice of individual components depends on the complete brake system.

Fitment & Compatibility

Select this kit only for the specified Currie Pro-Tour unit-bearing floating rear axle. DS-1180 defines the caliper-bracket, hub-registration and wheel-pattern requirements; no generic vehicle application is implied. The kit supplies service and MC4 parking calipers, while hydraulic flexlines, parking cables and cable adapters are separate. Confirm the 17-inch wheel template and the available cable travel.
