{"product_id":"wilwood-370-9542","title":"Wilwood Front Outer Bearing Cone, A3, 0.844-Inch Nominal ID","description":"\u003cp\u003eThis Wilwood outer tapered bearing cone belongs to the A3 arrangement in the designated front rotor-hub. Its nominal 0.844-inch spindle bore matches the size of another bearing family, but not that family's race geometry. Established in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake design and manufacturing work covers calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Across motorsport, street-performance, and specialized applications, those components are specified as parts of a complete braking system rather than chosen in isolation.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 370-9542\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Material:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Bare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCone ID:\u003c\/strong\u003e 0.844 inch nominal; 0.8437-inch reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing set:\u003c\/strong\u003e A3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e M12649\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatching race:\u003c\/strong\u003e 370-9245\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e One outer cone\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eUse race 370-9245 and confirm the A3 identification before fitting.
