Product details
This black Superlite rear package gives the specified Gladiator JT a 13.50-inch SRP drilled-and-slotted rotor assembly. The supplied hydraulic hoses support the service-brake installation; the existing parking brake remains part of the completed system. Based in Camarillo, California, Wilwood Engineering has designed and manufactured disc brake systems and components since Bill Wood founded the company in 1977. Its work spans motorsport, street-performance and specialized applications, with a product range covering master cylinders, calipers, brake rotors, valves, fittings and brake lines. These parts must be chosen for the requirements of the entire brake system.
