{"product_id":"wilwood-120-8924","title":"Wilwood GM Metric D154 Cast-Iron Floating Caliper with 2.75-Inch Stainless Piston","description":"\u003cp\u003eThis GM Metric iron caliper uses a single 2.75-inch stainless piston in a casting made for that bore size. It is a new component for the documented GM Metric racing or conversion arrangement. Its larger piston option should be chosen to achieve the intended hydraulic balance; approval of another bore size does not establish eligibility for this caliper. 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: 120-8924\u003c\/li\u003e\n\u003cli\u003eCaliper type: GM-Metric-Iron Single Piston Floater\u003c\/li\u003e\n\u003cli\u003eConstruction: Cast Iron\u003c\/li\u003e\n\u003cli\u003eFinish: Bare\u003c\/li\u003e\n\u003cli\u003ePiston bores: 2.75 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 1\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 5.94 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.04 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.81–1.04 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 11.00–11.75 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Floating\u003c\/li\u003e\n\u003cli\u003eHandedness: Not restricted to one side; correct mounting and bleed orientation required\u003c\/li\u003e\n\u003cli\u003eMounting centers: 5.46 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.69 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 0.48 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: M10 x 1.50\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: D154\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 8.7 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 2.9 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 4.3 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the D154 mounting and pad format, rotor dimensions and brake-circuit sizing.
