Product details
This right-hand red BNSL4R is the booted-piston, billet aluminum Narrow Superlite four-piston caliper. Four 1.25-inch bores and a nominal 1.10-inch rotor opening identify its hydraulic and rotor configuration. It is an individual component for a package designed around its radial mounting dimensions. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.

Fitment & Compatibility
Check the right-hand installation against the drawing before substituting for another Superlite series part. Verify 5.98-inch mounting centers, 2.32-inch mount height and the rotor’s friction-track position. The permitted rotor diameter and width, wheel-spoke envelope and NPT fitting clearance must all be confirmed with the complete assembly.
