{"product_id":"wilwood-270-9320","title":"Wilwood Front Hat-Mount Hub for Ford Mustang (1970-1973), A13\/A12 Bearings","description":"\u003cp\u003eThis Wilwood Mustang front hub is the hat-mount configuration specified for A13 inner and A12 outer bearing sets. It gives the 1970-1973 spindle application a separate wheel hub and brake-hat interface, with both listed five-lug wheel patterns. 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 270-9320\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\u003eIncluded components:\u003c\/strong\u003e Bearing races and screw-on aluminum cap\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 370-0884 \/ A13 set (fitment reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter bearing specification:\u003c\/strong\u003e 370-0882 \/ A12 set (fitment reference)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck the bearing series against the installed spindle; a second Mustang hub uses different bearings despite similar outside dimensions.
