Product details
The split XRZ hub is the axle-clamping component for either supported rotor-plate arrangement. Its 46-spline interface and five-bolt plate attachment distinguish it from earlier Gen II Sprint hubs. Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.
