{"product_id":"wilwood-120-9690-rd","title":"Wilwood Red DynaPro Single Caliper, 3.75-Inch Lug Pattern with Two 1.38-Inch Pistons","description":"\u003cp\u003eThis red DPS is the two-piston, 1.38-inch-bore caliper with 3.75-inch mounting centers. Its billet housing uses the nominal 0.38-inch rotor opening. The exact caliper dimensions should be matched when servicing an existing brake package, particularly because compact DynaPro Single models also exist with narrower lug spacing. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-9690-RD\u003c\/li\u003e\n\u003cli\u003eCaliper type: Dynapro Single\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Red Powder Coat\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.38 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 2\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 1.50 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: 6.00–13.00 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: 3.75 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 1.92 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 6812\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 3 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 1.1 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 2.3 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eConfirm the 3.75-inch bracket interface and 1.92-inch mount height before ordering.
