{"product_id":"wilwood-120-7740-p","title":"Wilwood Polished Right Rear Harley-Davidson GP310 Caliper with Four Stainless Pistons","description":"\u003cp\u003eThe polished right-rear GP310 is an individual four-piston caliper for compatible Harley-Davidson rear-brake packages. Its billet aluminum body attaches through a 3.50-inch lug pattern to the required rear bracket. The separate bracket determines the model-specific installation and is not part of this caliper listing. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-7740-P\u003c\/li\u003e\n\u003cli\u003eCaliper type: GP310 Motorcycle Rear\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Polish\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.25 \/ 1.25 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: 2.46 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: 0.18–0.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 9.00–11.50 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Lug\u003c\/li\u003e\n\u003cli\u003eMounting side: Right Hand\u003c\/li\u003e\n\u003cli\u003eMounting centers: 3.50 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 1.55 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 3\/8-24\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 6208\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 3.65 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 0.63 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 2.1 lb\u003c\/li\u003e\n\u003cli\u003eSupplied brake components: Individual GP310 caliper with brake pads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the caliper and rear bracket as a pair before confirming motorcycle fitment.
