Product details
Red six-piston Superlite calipers work over 14-inch drilled/slotted rotors in this Wilwood front truck conversion. The hats and replacement hubs are for the specified CPP drop-spindle arrangement. The complete hub and caliper geometry must match the installed spindle, rather than the vehicle model name alone. 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
The bracket system in DS649 is for the identified CPP truck spindle rather than a factory steering knuckle. Match its CP30106 version and the vehicle's individual year/model row. Ridetech rows need confirmation because they conflict with the CPP-only kit note. The 14-inch SRP friction ring and six-piston caliper require the larger clearance template; wheel bolt pattern alone cannot establish fit. Inspect hub bearings, register and wheel studs before assembling the hats, then route the separate hydraulic lines through full steering travel.
Match the individual model, year, submodel and brake configuration in the fitment table below.
