Product details
The improved Gen II Sprint hub supports a separate inboard rotor adapter. Its published spline descriptions disagree, so confirm the axle interface and adapter connection before selecting this replacement clamp hub. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.
