Product details
The H2 and 2500 HD rear package uses angled hose ends with imperial chassis adapters. Wilwood's written specification calls for straight NPT caliper fittings on the 14-inch lines. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.
