{"product_id":"wilwood-370-16723","title":"Wilwood Rear One-Ton Wide 5 Outer Bearing Cup, 3.125-inch Diameter","description":"\u003cp\u003eFor the outboard bearing in a one-ton Wide 5 hub, Wilwood specifies this steel race with a 3.125-inch outside diameter. A standard Wide 5 cup shares that nominal measurement, making the exact bearing pairing essential. 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 370-16723\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\u003eOutside diameter of cup:\u003c\/strong\u003e 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e One-ton Wide 5 outer bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatching cone:\u003c\/strong\u003e 370-16725\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e One cup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDocumented axle application:\u003c\/strong\u003e One-ton Wide 5 rear hub, including Wilwood 270-16772BD\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThe matched cone is 370-16725.
