Product details
This single bridge service assembly fits the specified FNSL4R and FNSL6R versions for 1.10-inch rotors. A 2.750-inch 1/4-20 socket bolt secures the matching spacer tube and nut across the bridge. This component comes from Wilwood Engineering's disc brake program, designed and manufactured for motorsport, street-performance and specialized applications. Bill Wood established the company in 1977; it is based in Camarillo, California. The range spans calipers, rotors, master cylinders, valves, fittings and brake lines, whose selection depends on the requirements of the complete braking system.
