Wilwood Drilled Rear Brake Conversion with Black Low-Profile Dynapro Calipers for Ford 8.8 Special Axles, 11-Inch Rotors and 2.50-Inch Offset

The drilled-and-slotted rotor option retains the black low-profile calipers and parking-shoe assemblies of this Ford 8.8 Special conversion. Its one-piece iron drum/rotors combine the service friction surface and mechanical parking drum without adding a wheel hub. This is a Wilwood Engineering conversion package. Bill Wood founded the company in 1977, and it is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized applications require each component to match the complete brake system.

Fitment & Compatibility
