Wilwood Black Superlite 6R Classic Front Brakes for 1960–1963 Chevy/GMC 2WD, 11.86-Inch Integral Rotor/Hubs

This Wilwood Superlite 6R kit is a front disc conversion for drum spindles for 1960–1963 Chevy and GMC 2WD Trucks. The 11.86-inch one-piece rotor/hub design is paired with six-piston Superlite calipers and BP-10 pads. From its Camarillo, California base, Wilwood Engineering designs disc brake systems for motorsport, street-performance and specialized needs. Founded in 1977 by Bill Wood, its range covers calipers, rotors, master cylinders, valves, fittings and brake lines chosen to work within a complete brake system.

Fitment & Compatibility

Use only the listed Chevrolet/GMC two-wheel-drive drum-spindle applications. DS-1225 separates 1963 spindles from 1960–1962 spindles; follow the appropriate hardware diagram. The kit includes the replacement integral rotor/hub casting, not a separate aluminum hub. Models covered: C10 Panel, C10 Pickup, Suburban and 1000 Series. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.

If a separate rear parking-brake conversion is also planned, a universal parking cable may need cable or vehicle changes; it is not part of this front kit.

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.

Manufacturer Warning

Applicable to the included brake pads only: Wilwood warns of exposure to arsenic, cadmium, hexavalent chromium compounds, lead, nickel, cobalt and antimony trioxide, chemicals known to California to cause cancer or reproductive harm. More information: www.P65Warnings.ca.gov.
