Product details

Wilwood’s black left Billet Narrow Superlite 6 combines a narrow lug-mount body with six differential-bore stainless pistons. The 1.62/1.12/1.12-inch layout and type 7416 pad shape determine its hydraulic and friction requirements. Camarillo, California is home to Wilwood Engineering, the disc brake company Bill Wood founded in 1977. Its design and manufacturing range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized brake systems.

Technical Details

  • Manufacturer part number: 120-13383-BK. Component: Billet Narrow Superlite 6 Lug Mount caliper.

  • Construction and surface: billet aluminum housing finished in Black powder coat.
  • Pad fit is type 7416. Match the pad dimensions and compound to the rotor and intended braking conditions.
  • Hydraulic inlet thread: 1/8-27 NPT. Use a fitting with the correct thread and sealing seat.

  • Caliper weight: approximately 5.2 lb.

Fitment & Compatibility

Use the 3.50-inch mount spacing to compare the bracket, then check the 2.85-inch height and rotor centerline. Match a nominally 1.10-inch-wide rotor and confirm clearance at both the rotor hat and the wheel.

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.
