Product details
The 1.930-inch N dimension identifies this dual-pattern Pinto/Mustang II hat hub. It retains the separate rotor hat at three threaded holes and must be selected with the matching bearings and rotor offset. From Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and their components. Founded by Bill Wood in 1977, it serves street-performance, motorsport and specialized applications with master cylinders, calipers, brake rotors, valves, fittings and brake lines. All components must suit the requirements of the complete system.

Fitment & Compatibility
Compare the spindle journals, bearing references and hub mounting faces with the complete brake assembly. A shared wheel bolt pattern alone does not establish hub interchangeability.
