Product details

Drilled/slotted 12.88-inch rotors and black Superlite 6R calipers form this Wilwood hub conversion for the CPP drop-spindle arrangement. Aluminum hubs and separate hats provide the required rotor mounting. This is an aftermarket-spindle kit, rather than a direct replacement for the original Chevrolet knuckle. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Match the actual CPP 2-inch drop spindle to the CP30101 specification in the instructions. The original factory spindle is excluded even when the vehicle model and year match the table. Confirm hub bearings, stud pattern and wheel registration before assembly. Choose compatible hydraulic lines separately and compare the intended wheels with the full clearance template.

Match the individual model, year, submodel and brake configuration in the fitment table below.
