Product details
This front hub serves the specified AMC spindle arrangement through an intermediate rotor adapter. AMC model identity alone is insufficient; compare the bearing references and mounting geometry with the installed conversion. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc brake systems and supplies master cylinders, calipers, brake rotors, valves, fittings and lines for motorsport, street-performance and specialized installations. Select each component around the complete system’s requirements.

Fitment & Compatibility
Identify the installed conversion and compare its hub drawing before ordering. The spindle, bearings, rotor connection and caliper alignment must agree as a complete assembly.
