{"product_id":"wilwood-120-17200","title":"Wilwood XRS4R Caliper for 0.81-Inch Rotor Width — 1.12\/1.12-Inch Bores, Anodized","description":"\u003cp\u003eWith 4 pistons and 1.12\/1.12-inch bore dimensions, the anodized Wilwood XRS4R brake caliper must be matched to the brake system rather than selected by finish alone. Its 0.81-inch rotor-width specification is separate from rotor diameter. The forged XRS4R is a four-piston radial caliper with an X-shaped center bridge and internal fluid passages. Its 10416 pad outline differs from the older Narrow Superlite pad shape. Match the radial bracket, rotor width and hydraulic bore before choosing this individual component. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-17200\u003c\/li\u003e\n\u003cli\u003eComponent: Forged XRS4R 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\u003ePistons: 4; stainless steel; bore dimensions 1.12\/1.12 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 1.98 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 10416; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.81 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.75–0.84 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 11.75–14.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 4.9 lb\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\u003eCompare the caliper drawing with your radial bracket before ordering. The 5.98-inch mounting centers and 1.12\/1.12-inch bores must suit the installed rotor offset and hydraulic system. Axle placement is determined by the engineered brake package, not by a generic caliper designation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Calipers\/CaliperProd?itemno=120-17200\"\u003eWilwood caliper specifications\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eFor a modified brake system, provide its existing component specifications along with the vehicle details.
