Wilwood Rear Inner Bearing Race for One-Ton Wide 5 Hubs, 3.346-inch OD

The one-ton Wide 5 inner bearing arrangement uses this Wilwood 3.346-inch outside-diameter race. It is the separate steel cup in which the inner roller bearing runs, not a standard Wide 5 inner cone or seal. 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.
