{"product_id":"wilwood-120-17866","title":"Wilwood XRD Anodized Lug-Mount Brake Caliper, Four 1.75-Inch Pistons, 0.38-Inch Rotor Width","description":"\u003cp\u003eThis Forged XRD caliper is the thin-rotor, 1.75-inch-bore version of Wilwood’s four-piston lug-mount racing component. Top-supported pads and Quick-E-Clip retention leave the lower body profile open for installations where hub-side space is limited. A Type III anodized finish covers the forged aluminum housing. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-17866\u003c\/li\u003e\n\u003cli\u003eCaliper type: Forged XRD Lug Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Forged Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.75 \/ 1.75 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 4.80 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.38 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.25–0.38 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 10.00–13.06 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Lug\u003c\/li\u003e\n\u003cli\u003eHandedness: Not restricted to one side; correct mounting and bleed orientation required\u003c\/li\u003e\n\u003cli\u003eMounting centers: 5.25 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 2.10 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 7812\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 6.36 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 2.1 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 3.8 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eTreat the XRD as a dimensional replacement or conversion component, not a universal bolt-on vehicle part.
