Product details
A6 and A34 bearing references identify this hat-mount Camaro hub's spindle arrangement. Use it with the correct separate rotor hat and confirm wheel-flange position before choosing a replacement. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around 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.
