Wilwood Front Outer Tapered Bearing, A34, 0.844-Inch ID

This A34 Wilwood outer bearing cone fits the nominal 0.844-inch spindle seat of its designated front hub assembly. It shares a listed cup with another bearing configuration but not that configuration's cone bore. Wilwood's range extends from calipers and brake rotors to master cylinders, valves, fittings, and brake lines, all selected to meet the requirements of a complete brake system. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street-performance, and specialized uses.
