Product details
This GM truck front package uses 31-inch -4 hoses and straight NPT caliper fittings. The larger hose interfaces and long routing distinguish it from the shorter -3 passenger-car kits. Camarillo, California is home to Wilwood Engineering, founded by Bill Wood in 1977. Wilwood designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Those components need to be selected together around the complete brake system's requirements.
