Wilwood Anodized Right FNSL6R Six-Piston Caliper, 1.10-Inch Rotor-Width Channel

The anodized right FNSL6R has a nominal 1.10-inch rotor-width channel and six differential stainless pistons. It retains the 4.04-square-inch effective area and 7416 pads of this narrow Superlite bore combination. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. The company makes and designs disc brake components and systems for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Technical Details

• Manufacturer part number: 120-11780. Component: Forged Narrow Superlite 6 Radial Mount caliper.
• Supply: one brake caliper, not a complete axle brake kit. Match the mating rotor, pads, bracket and connection hardware to the installation.
• Caliper weight: approximately 5.0 lb.
• Type III anodize finish on a forged aluminum caliper body.
• Hydraulic inlet thread: 1/8-27 NPT. Use a fitting with the correct thread and sealing seat.
• The rotor channel is specified for 1.10-inch nominal width. Rotor outside diameter: 11.75 to 14.00 inches. Specified rotor-width limits: 1.00–1.10 inch.
• 5.98-inch radial mounting pattern, right hand; mounting height 1.45 inches and hole size 0.39 inch.
• 6 stainless steel pistons with 1.62/1.12/1.12-inch bore groups. The specified effective area is 4.04 sq in.
• Piston dust boots: not fitted.
• Brake pad profile 7416; select friction material for the actual operating conditions.

Fitment & Compatibility

Match this intermediate-width body to the rotor hat and radial bracket. The 5.98-inch mount centers do not identify whether a 1.10- or 1.25-inch rotor-width version is required.

Ask PMB Performance to check the complete brake arrangement before ordering. Our team brings over 20 years of experience; photographs and measured bracket and rotor dimensions make that check more useful.
