Product details
The nominal 0.866-inch bore separates this Wilwood outer cone from the smaller-bore alternative used with the same listed race. Wilwood identifies A12 and A16 bearing sets for this steel tapered roller component. This component comes from Wilwood Engineering, the disc brake manufacturer established by Bill Wood in 1977 and based in Camarillo, California. Its design and manufacturing range includes calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications. Selection depends on the requirements of the complete brake system.
