Product details
This Oldsmobile hub uses a press-on steel bearing cap rather than the screw-on cap on many other street hubs. The wheel flange is five-on-five; the exact year and spindle scope require confirmation across Wilwood references. Established in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems. Its master cylinders, calipers, brake rotors, lines, fittings and valves support motorsport, street-performance and specialized applications, with each component selected for its role in the complete brake system.

Fitment & Compatibility
Compare the spindle journals, bearing references and hub mounting faces with the complete brake assembly. A shared wheel bolt pattern alone does not establish hub interchangeability. Product characteristics and narrative specify 1940–1952 Oldsmobile, while DS719 says 1940–1951. Confirm the exact spindle application with Wilwood.
