Wilwood 14-Inch Drilled Front Brake & Hub Package, Red Six-Piston Calipers, GM G-Body/S-Series/Isuzu Hombre (1978–2003)

Red powder-coated six-piston calipers accompany 72-curved-vane SRP rotors in this Wilwood front hub kit. The 14-inch friction rings mount to aluminum hats, with replacement hubs locating the assembly on the listed disc-spindle chassis. This package requires planned wheel clearance and qualified machining of the original spindle rather than merely substituting larger rotors. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Use DS879 to establish the bracket hole preparation and the minimum casting relief needed around the original caliper ears. Check the vehicle's exact application row, especially compact-truck drivetrain conditions. Replacement hubs increase wheel position 0.10 inches per side. Confirm that the chosen wheel clears the caliper through its full envelope and that the separately sourced hydraulic connections suit the completed front/rear brake system.

Match the individual model, year, submodel and brake configuration in the fitment table below.
