{"product_id":"wilwood-120-7737","title":"Wilwood Chrome GP310 Left Front Motorcycle Brake Caliper, Harley-Davidson (1984–1999), and 1983 XR1000","description":"\u003cp\u003eThe chrome left-front GP310 supplies a four-piston caliper for the supported 1984–1999 Harley-Davidson front brake. Its billet body mounts directly to the appropriate fork leg, with 3.44-inch centers and a 3\/8-24 inlet. A left-hand configuration is required where the rotor and fork mounting call for this side. 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: 120-7737\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: Chrome\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: Left 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\u003eCheck the actual fork rather than using year alone, especially on modified motorcycles. Wilwood’s application excludes Springer and four-speed FL models. Match rotor thickness and diameter to the stated limits, confirm pad contact and wheel space, and retain the correct brake-line connection and system fluid requirements. 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.
