{"product_id":"wilwood-270-8779","title":"Wilwood Front Mopar B-Body Drum-Spindle Hub for Vented Rotors (1962–1972)","description":"\u003cp\u003eAn A6 inner bearing and A2 outer bearing locate this aluminum Wilwood front hub on the specified 1962–1972 Mopar B-Body drum spindle. Its vented-rotor offset works with a separate rotor adapter, providing the hub portion of a matched brake conversion rather than a complete brake assembly. Founded in 1977 by Bill Wood, Wilwood Engineering designs and manufactures disc-brake systems from Camarillo, California. Its range of calipers, rotors, master cylinders, valves, fittings and brake lines serves motorsport, street-performance and specialized applications. Individual parts must be matched to the requirements of the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-8779\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\u003eRotor adapter choices:\u003c\/strong\u003e 300-3307 or 300-3099, selected to match the rotor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.5 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\u003eVerify the B-Body drum spindle and bearing journals, particularly if the suspension has already been modified.
