{"product_id":"wilwood-120-9688-lp","title":"Wilwood DynaPro Single Long-Piston Caliper, 1.38-Inch Bores, 3.25-Inch Mount, 0.19-Inch rotor width","description":"\u003cp\u003eThe long-piston DynaPro Single is the extra-thin-rotor version of the 1.38-inch-bore DPS caliper. Two stainless pistons work in an anodized billet housing with 3.25-inch lug centers. Its nominal 0.19-inch rotor opening makes it a distinct configuration from the standard 0.38-inch body. 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: 120-9688-LP\u003c\/li\u003e\n\u003cli\u003eCaliper type: Dynapro Single\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.38 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: 0.19 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.15–0.25 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: 3.25 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\u003eIdentify the long-piston variant when servicing an existing assembly; lug spacing and bore alone do not establish equivalence.
