{"product_id":"wilwood-120-17870","title":"Wilwood Narrow DynaPro Anodized Radial Caliper, 1.62-Inch Pistons, 0.25-Inch Rotor Width","description":"\u003cp\u003eThe anodized Narrow DynaPro radial caliper combines four 1.62-inch stainless pistons with a body specified for a 0.25-inch-wide rotor. This thin-pad configuration uses 4.75-inch radial mounting centers and an M10 x 1.25 hydraulic connection. Its narrow package must be selected by the installed brake geometry rather than by the vehicle badge. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-17870\u003c\/li\u003e\n\u003cli\u003eCaliper type: Narrow Dynapro Radial Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.62 \/ 1.62 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: 4.12 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.25 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.25–0.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 10.75–12.19 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Radial\u003c\/li\u003e\n\u003cli\u003eHandedness: Not restricted to one side; correct mounting and bleed orientation required\u003c\/li\u003e\n\u003cli\u003eMounting centers: 4.75 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 1.61 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: M10 x 1.25\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: 4.1 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck the pad thickness and mounting drawing before substituting for another DynaPro model.
