Product details
An A6 inner bearing and A2 outer bearing locate this aluminum Wilwood front hub on the specified 1962–1972 Mopar B-Body drum spindle. Its vented-rotor offset works with a separate rotor adapter, providing the hub portion of a matched brake conversion rather than a complete brake assembly. Founded in 1977 by Bill Wood, Wilwood Engineering designs and manufactures disc-brake systems from Camarillo, California. Its range of calipers, rotors, master cylinders, valves, fittings and brake lines serves motorsport, street-performance and specialized applications. Individual parts must be matched to the requirements of the complete system.

Fitment & Compatibility
Verify the B-Body drum spindle and bearing journals, particularly if the suspension has already been modified. Choose the six- or eight-bolt adapter needed by the rotor and check caliper alignment. A matching wheel pattern does not verify the hub-to-spindle fit.
