{"product_id":"wilwood-120-7736-p","title":"Wilwood Polished Right Front GP310 Harley-Davidson Brake Caliper (1984–1999), and 1983 XR1000","description":"\u003cp\u003eA polished billet body identifies this right-front GP310 for Wilwood’s documented 1984–1999 Harley-Davidson fitment. Four stainless pistons apply the pads in the direct leg-mount arrangement. The caliper has a 3\/8-24 inlet and the 3.44-inch mounting centers used by this earlier front version. 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: 120-7736-P\u003c\/li\u003e\n\u003cli\u003eCaliper type: GP310 Motorcycle Front (1984-1999)\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: 11.00–11.50 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: 3.44 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 2.33 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: 2.0 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\u003eConfirm the original fork and brake layout, excluding Springer and four-speed FL models. A rotor must match the caliper’s width and diameter limits, with correct pad contact and room inside the wheel. Follow the motorcycle’s fluid requirements, and confirm the right side rather than substituting a later or rear GP310. Wilwood also specifically includes the 1983 Harley-Davidson XR1000 front application; verify the same fork, rotor and mounting requirements.\u003c\/p\u003e\u003cp\u003ePMB Performance has over 20 years of experience helping customers with brake and parts fitment.
