Wilwood 12.88-Inch SRP Front Hub Kit for 1968–1972 Ford F-100 2WD, Black Six-Piston Superlite Calipers

This Wilwood Superlite 6R kit is a front 12.88-inch hub upgrade for 1968–1972 Ford F-100 4 x 2 Drum Spindles. This later F-100 hub package uses separate aluminum hubs, 12.88-inch rotors and six-piston Superlite calipers. Wilwood Engineering began in 1977 with founder Bill Wood and is based in Camarillo, California. It designs disc brake systems and components for racing, performance-road and specialized use, from calipers and rotors to master cylinders, valves, fittings and brake lines; the complete system determines component selection.

Fitment & Compatibility

Use the listed 1968–1972 F-100 4 x 2 factory drum spindles and the specific DS-1266 hub/bearing configuration. The supplied hubs have 5 x 4.50/5 x 4.75-inch wheel patterns. The 1957–1967 spindle kit uses a different hub; choose by the actual spindle and bearings. Models covered: F-100. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.

For fitment assistance, provide PMB Performance with the existing brake configuration and measured mounting/wheel details. Our 20+ years of parts experience support checking the complete assembly rather than relying only on a model name.
