Product details
This GM truck kit uses larger -4 hose connections rather than the -3 fittings found in many passenger-car conversions. Its 27-inch lines join 7/16-24 inverted-flare chassis adapters to 90-degree NPT caliper fittings. Since its founding by Bill Wood in 1977, Wilwood Engineering has developed a range serving motorsport, street-performance and specialized brake applications. Based in Camarillo, California, it designs and manufactures disc brake systems, calipers, brake rotors, master cylinders, valves, fittings and brake lines. Each component should be selected for compatibility with the complete braking system.

Fitment & Compatibility
The manufacturer identifies front 1999–2006 GM 1500 and 2500 conversions with 13.38- or 16-inch rotors. Confirm the specific truck brake kit, chassis thread and -4 interfaces; do not mix these fittings with a -3 hose simply because the caliper port is NPT.
