Product details
A bolt-on lug-drive plate distinguishes this rear 55XD hub from the conventional eight-bolt rotor version. The dynamic rotor connection requires the specified lug-drive rotor and retention components. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.
