Product details
The Wilwood Forged Narrow Superlite 6R Dust Seal shown here is specified for 1.25-inch rotor width, 5.98-inch radial mounting and 1.62/1.12/1.12-inch piston bores. This left-hand red 6-piston component is selected by brake-system geometry rather than vehicle year alone. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.

This six-piston narrow Superlite combines radial attachment with piston dust wipers. Differential bores distribute pad loading, while the 7416 pad shape and exact rotor-width version determine the mating friction components.
Fitment & Compatibility
Compare the installed rotor’s nominal width with this exact caliper version. Before assembly, verify pad sweep, caliper-to-wheel clearance and the hose fitting’s thread and sealing method.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
