{"product_id":"wilwood-120-9691","title":"Wilwood DynaPro Black Lug-Mount Caliper, Four 1.75-Inch Pistons, 1.25-Inch Rotor Width","description":"\u003cp\u003eThe black DynaPro lug caliper is the four-piston, 1.75-inch-bore option for a nominal 1.25-inch-wide rotor. It uses a forged aluminum housing and top-supported pads. The published 4.80-square-inch piston area and 5.25-inch mounting pattern need to match the brake package as carefully as the external dimensions. 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: 120-9691\u003c\/li\u003e\n\u003cli\u003eCaliper type: Dynapro Lug Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Forged Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Black Powder Coat\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: 1.25 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 1.19–1.27 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\u003eCheck the rotor against the 1.19–1.27-inch thickness limits and verify a suitable diameter within the specified envelope.
