Wilwood Front Drilled/Slotted Rotor and AERO6 Caliper Kit for Chevrolet/GMC DSE C10 Trucks (1973–1987), Red / 14.25 Inch

AERO6 six-piston calipers and 14.25-inch rotor rings form this front brake conversion for the Detroit Speed C10 drop-spindle arrangement. Red calipers and 14.25-inch SRP drilled & slotted rotors are the selected configuration. Separate hats fit over the matching hubs, so the kit selection must follow the installed DSE spindle and hub combination. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems, with selection governed by the complete brake installation.

Fitment & Compatibility

Requires the Detroit Speed and Engineering 1973–1987 C10 drop spindle; original equipment spindles are not compatible. The application table separates Chevrolet Blazer, C10/C10 Pickup, C10 Suburban, K5 Blazer, R10 Pickup and R10 Suburban from GMC C15/C1500 Suburban, C1500 Pickup, Jimmy, C15 Suburban, C1500 Suburban, R1500 Pickup and R1500 Suburban. Match each year and spindle entry. The two hat drillings do not change the retained hub wheel pattern. The table below preserves the individual vehicle and brake-option entries; select the complete matching row before ordering.

With over 20 years of parts and application experience, PMB Performance can help compare this assembly with your existing brakes. Supply the hub, axle or spindle specification and wheel-clearance information before ordering.
