Wilwood Front Inner Bearing for Packard Conversion Hubs (1941–1956)

This Wilwood inner wheel bearing cone serves the specified 1941–1956 Packard conversion hub on a 1.3125-inch spindle journal. It is a separate roller assembly and does not include the cup or seal needed to complete the hub. Wilwood Engineering designs and manufactures complete disc brake systems as well as calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Based in Camarillo, California, it was founded by Bill Wood in 1977. The range serves motorsport, street-performance, and specialized applications, requiring each part to be matched to the system in which it operates.
