{"product_id":"wilwood-270-7283","title":"Wilwood Front Vented-Brake Hub for Chevrolet (1955-1957)","description":"\u003cp\u003eThe 1955-1957 Chevrolet spindle application of this Wilwood front hub uses an intermediate adapter to mount a vented rotor. Its bare aluminum construction and two five-lug wheel bolt circles are specified for a custom brake assembly rather than an integral replacement rotor. Wilwood's range extends from calipers and brake rotors to master cylinders, valves, fittings, and brake lines, all selected to meet the requirements of a complete brake system. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street-performance, and specialized uses.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-7283\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Bare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Front\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel bolt pattern:\u003c\/strong\u003e 5 x 4.75 in; 5 x 4.50 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel stud thread:\u003c\/strong\u003e 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor adapter patterns:\u003c\/strong\u003e 6 x 6.25 in; 8 x 7.00 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.3 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner bearing specification:\u003c\/strong\u003e 370-0879 \/ A6 set (fitment reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter bearing specification:\u003c\/strong\u003e 370-0877 \/ A2 set (fitment reference)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the original or replacement spindle dimensions and bearings on the car.
