Product details

This large-diameter Bronco rear conversion pairs black Superlite 4R calipers with 14-inch GT-slotted Spec-37 rotor rings. Iron hats and internal parking shoes complete the matched brake assembly for the Big Ford New Style flange and 2.36-inch axle offset. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It develops disc brake systems and components, designing and manufacturing calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. A correct conversion matches those individual components to the complete braking system.
