{"product_id":"wilwood-140-7676-p","title":"Wilwood Polished Front Dynalite Hub Conversion for 1955–1957 Chevrolet — Plain-Face Rotors, 12.19-inch","description":"\u003cp\u003eThe polished\/plain-disc combination preserves an uninterrupted rotor face in this front conversion. Its polished 4-piston calipers and 12.19-inch plain-face rotors are assembled around the requirements of 1955–1957 Chevrolet passenger cars. Wilwood Engineering, founded by Bill Wood in 1977, designs and manufactures disc brake systems in Camarillo, California. The range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component chosen to suit the complete brake system.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThe Tri-Five Chevrolet application list covers Bel Air, Nomad, One-Fifty, Two-Ten and Sedan Delivery from 1955–1957, together with the listed 1957 Del Ray. Verify the original spindle before selecting the hub kit, especially on a car that has already received a disc conversion or suspension change. New hubs supply two wheel bolt-circle options and 1\/2-20 studs; check that the intended wheels match the selected pattern. DS449 describes the bearing and hub assembly sequence and provides the clearance profile for the 12.19-inch rotor. The kit changes the hub and braking hardware but does not include replacement spindles, a booster or a master cylinder. Review those existing components as part of the finished conversion rather than treating the new calipers as a complete hydraulic system.\u003c\/p\u003e\u003cp\u003eRead the full application entry below, including the brake, spindle and numbered-note fields that apply to that vehicle.\u003c\/p\u003e\u003ch3\u003ePackage and installation requirements\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIncluded hubs offer 5 x 4.5 and 5 x 4.75-inch wheel bolt circles and 1\/2-20 studs.
