Wilwood Forged Narrow Superlite 6R Dust Seal, Left 6-Piston Radial Brake Caliper, Black, 1.62/1.12/1.12-Inch Bore for 1.25-Inch-wide Rotor

Choose this left-hand Wilwood Forged Narrow Superlite 6R Dust Seal when the installation calls for 1.62/1.12/1.12-inch pistons and 1.25-inch rotor width. The black 6-piston body uses a 5.98-inch radial pattern; check its complete geometry before substituting another caliper. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Plan the caliper installation with the rotor centered in the pad gap. Verify attachment hardware, hose connection and accessible upper bleeders, then confirm the brake system’s hydraulic balance.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.

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.
