Product details

Red AERO4 calipers sit over 14-inch SRP rotors in this six-lug GM rear conversion. The package includes internal parking-brake shoes, and its 2.46-inch axle-offset requirement must be checked against the installed housing. Wilwood Engineering designs and manufactures the disc brake systems and components used throughout its motorsport, street-performance and specialized product range. Bill Wood established Wilwood in 1977, and the company is based in Camarillo, California. Its calipers, brake rotors, valves, master cylinders, brake lines and fittings are selected according to the demands of the whole brake installation.

Fitment & Compatibility

It applies only to the corresponding year/model entries for K-series, Blazer/K5 Blazer, Jimmy and Suburban vehicles within 1971–1991. A compatible cable arrangement is needed to actuate the parking shoes.

Consult DS1677 for the housing dimensions and rotor-hat installation. Required axle measurements include a 3.55-inch register and 6 x 5.5-inch stud pattern; the flange limit is 7.05 inches with a 0.050-inch x 45-degree chamfer. Obtain the appropriate parking cables/clevis connections and hydraulic hoses separately.
