{"product_id":"wilwood-120-16683","title":"Wilwood Anodized FNSL4R Brake Caliper with Stainless Pistons","description":"\u003cp\u003eCheck the 5.98-inch mounting centers before fitting this anodized Wilwood FNSL4R brake caliper. The component is sold individually and uses 1.38\/1.38-inch bores in its 0.95-inch rotor-width configuration. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake system. The Forged Narrow Superlite 4R is a four-piston radial caliper using the 7416 pad outline. Its nominal 0.95-inch-wide rotor configuration must be matched to the mounting height and hydraulic balance of the installation. Wheel clearance is determined by the entire caliper-and-bracket envelope.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16683\u003c\/li\u003e\n\u003cli\u003eComponent: Forged Narrow Superlite 4 Radial Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Universal mounting orientation; verify axle position\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.95 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.89–0.99 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 11.42–14.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 5.0 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.38\/1.38 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 3.00 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 7416; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 5.98 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.39 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 1.45 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck bracket location and rotor sweep using the installation drawing; 5.98-inch radial mounting alone does not establish a vehicle fit.
