Product details
Low-profile Dynapro calipers allow this BOP rear conversion to use an 11-inch rotor package where wheel space is limited. The black four-piston service calipers work with BP-10 pads, and the separate internal-shoe assemblies provide mechanical parking-brake operation. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines, with each component chosen to suit the complete brake system.

Fitment & Compatibility
Use only with the BOP housing-end configuration, 2.75-inch bearing and 2.75-inch axle offset shown in DS1033. Some 14-inch wheels may clear, but their barrel and spokes must match the diagram. Hoses and vehicle-specific parking-cable connections are separate.
