Wilwood Front 13.06-Inch Rotor Kit with Black FNSL6R Calipers for Chevrolet/GMC DSE C10 Trucks (1973–1987), Drilled/Slotted

Black calipers and 13.06-inch SRP drilled & slotted rotors are the selected configuration. The FNSL6R front conversion pairs six-piston Superlite calipers with 13.06-inch rotors for the DSE C10 drop-spindle setup. Its rotor rings bolt to separate short-offset hats while the existing matching wheel hubs remain in use. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Each component must suit the surrounding brake system.
