Product details
Black Superlite 6R calipers and 14-inch drilled/slotted rotors form this Wilwood front truck package. Replacement hubs and separate hats are matched to the selected CPP drop spindle, with 1.25-inch-wide Spec-37 friction rings. The larger brake package needs the wheel drawing specific to this kit. 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
DS649 ties the brake mount to CPP CP30106-2, CP30106-3 or CP30106-4, selected for the truck's production configuration. The fitment table also names Ridetech, but the exact kit note limits the fit to CPP; obtain confirmation for those entries before installation. The drilled/slotted ring is 14.00 inches across and 1.25 inches wide, carried by a separate hat on the five-lug hub. Check the larger wheel template, bearing engagement and registration, then select hydraulic connections appropriate to the chassis.
