{"product_id":"wilwood-120-15753","title":"Wilwood Anodized GP320A Caliper, Lug Mount, 1.25\/1.25-Inch Bores","description":"\u003cp\u003eThis anodized Wilwood GP320A brake caliper uses a 3.50-inch lug mount and the 0.81-inch rotor-width configuration. It is sold as one caliper, with its piston and mounting specification selected for the complete brake assembly. Based in Camarillo, California, Wilwood Engineering has its origins in the company Bill Wood founded in 1977. Its designs and manufactured disc brake products cover calipers and rotors alongside master cylinders, valves, fittings and lines. Motorsport, street-performance and specialized installations each require components selected for the complete system. The GP320A is a compact billet four-piston brake caliper using 6211-shape pads. Select the actual bridge width and mounting geometry for the installation; the family name alone does not distinguish the thin-rotor and vented-rotor configurations.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-15753\u003c\/li\u003e\n\u003cli\u003eComponent: GP320 Caliper; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Universal mounting orientation; verify axle position\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Billet aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.25\/1.25 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 2.46 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 6211; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.81 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.75–0.81 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 9.00–11.50 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 2.1 lb\u003c\/li\u003e\n\u003cli\u003eMounting interface: Lug; mounting centers 3.50 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.39 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 1.63 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the 3.50-inch lug attachment to the existing bracket, then check caliper centering over the 0.81-inch nominal-width rotor. Axle placement is determined by the engineered brake package, not by a generic caliper designation. The 1\/8-27 NPT connection must use the correct fitting and seal.
