Product details
For the outboard bearing in a one-ton Wide 5 hub, Wilwood specifies this steel race with a 3.125-inch outside diameter. A standard Wide 5 cup shares that nominal measurement, making the exact bearing pairing essential. 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.
