Product details
This Wilwood A18 inner cone supplies the roller assembly for the specified Ford F-150 conversion hub, using a 1.4961-inch reference spindle bore. The bare-steel bearing is a service component, not a complete inner-and-outer bearing kit. Established in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake design and manufacturing work covers calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Across motorsport, street-performance, and specialized applications, those components are specified as parts of a complete braking system rather than chosen in isolation.
