Select red four-piston rear brakes for the measured Chevrolet and GMC C1500 Pickup axle. Match its 3.25-inch offset and five-lug configuration. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its product range includes brake rotors, calipers, master cylinders, valves, fittings and brake lines, selected individually to match the complete brake system.

Fitment & Compatibility

Applies to the listed 1988–1998 Chevrolet and GMC C1500 Pickup five-lug, two-wheel-drive axle configurations with a measured 3.25-inch offset. The table below distinguishes the early front-brake/chassis options and later five-lug versions; an Iron ProSpindle entry does not replace the rear-axle checks. Compare axle-flange registration, housing ends and wheel clearance before ordering. The factory parking cable must be modified using the included cable-end adapter kit. Hydraulic flexlines are separate, and the original rubber hoses do not adapt directly to these calipers.
