{"product_id":"wilwood-120-15988","title":"Wilwood Anodized FNSL6R-ST Right Caliper — 5.98-Inch Mount and 1.25-Inch Rotor Width","description":"\u003cp\u003eThis anodized Wilwood FNSL6R-ST right brake caliper uses a 5.98-inch radial mount and the 1.25-inch rotor-width configuration. It is sold as one caliper, with its piston and mounting specification selected for the complete brake assembly. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement. The Forged Narrow Superlite 6R-ST uses radial mounting and six Thermlock insulated pistons. Radial mounting permits bracket adjustment but still requires accurate rotor centering, mounting height and pad sweep. Check the differential bores when matching an existing brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-15988\u003c\/li\u003e\n\u003cli\u003eComponent: Forged Narrow Superlite 6 Radial Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Right\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 1.19–1.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 11.75–14.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 5.0 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 6; Thermlock insulated; bore dimensions 1.62\/1.12\/1.12 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 4.04 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.
