Wilwood Red Dynapro Rear Parking Kit with Plain 11-Inch Drum/Rotors, Ford 8.8 Special Axle Geometry and 2.50-Inch Offset

The plain-face red-caliper version provides a low-profile service brake and internal mechanical parking system for the matched Ford 8.8 Special axle. The iron drum/rotors and mounting brackets must align with the measured housing end and axle-flange offset. The braking components are manufactured by Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. The company's design and manufacturing work includes disc brake systems, calipers, rotors, master cylinders, valves, fittings and brake lines. Across motorsport, street-performance and specialized applications, each selected part needs to suit the complete system.
