Product details

This front hub conversion fits the specific aftermarket drop spindles approved for the listed Chevrolet and GMC trucks. Black AERO6 calipers operate 14-inch GT rotor rings on aluminum hats and hubs; the spindle itself and the required hydraulic hoses are separate components. Wilwood Engineering is based in Camarillo, California. Bill Wood founded its disc brake system and component business in 1977. The manufacturer designs and produces calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses. Each item must suit the rest of the brake system.

Fitment & Compatibility

Identify the exact CPP or Ridetech spindle in the current application below. DS1056 documents CPP CP30106-2 for 1963–1970, CP30106-3 for 1971–1972 and CP30106-4 for 1973–1987. Other drop spindles are not implied. Verify wheel pattern, bearings, hose choice and brake bias.

The documented CPP drop-spindle references are CP30106-2 (1963–1970), CP30106-3 (1971–1972) and CP30106-4 (1973–1987). Wilwood also identifies specific Ridetech drop-spindle applications in its current compatibility listing; verify the installed part rather than assuming all dropped spindles fit. Separate front hose references are 220-7056, 220-11237 and 220-12168, with 220-7699/220-8307 among length alternatives. A parking-cable change is relevant only to a separate rear-brake conversion.

Use the fitment table below for the complete model, year, submodel and brake-option conditions; every listed condition must match the installed vehicle.
