Wilwood Black Superlite Front SRP Package for Bronco Dana 44 Disc Spindles (1976–1977), 14-Inch Rotors

This drilled-and-slotted front kit uses black Superlite 6R calipers on the later early-Bronco disc-spindle arrangement. The 14-inch rotor rings attach to hats over the compatible existing hubs. Wilwood Engineering is a Camarillo, California manufacturer founded by Bill Wood in 1977. Disc brake design and manufacturing extend across calipers, brake rotors, master cylinders, valves, fittings and brake lines. Parts for street-performance, specialized applications and motorsport must be selected to meet the requirements of the complete brake system.
