Product details

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
For the CPP truck arrangement, identify the installed CP30106-2/3/4 spindle against DS649 before choosing rotors or hubs. The brake kit supplies neither that spindle nor a universal substitute for other suspension hardware. The preserved Ridetech applications remain subject to confirmation of the mounting interface. This GT package uses 72-curved-vane, 14-inch friction rings on the specified five-lug hub layout. Compare the actual wheel template and inspect tire, bearing and registration details before completing the separate hydraulic plumbing and brake test.
