{"product_id":"wilwood-270-8773","title":"Wilwood Front Hub for Mopar A-Body 9-Inch Drum Spindles, Solid Rotor (1965-1972)","description":"\u003cp\u003eA 9-inch drum-brake spindle requires this specific Wilwood A-Body front hub when building the corresponding solid-rotor conversion. Its spindle fit differs from the hub intended for 10-inch drums, despite sharing the same two five-lug wheel bolt circles. For Wilwood Engineering's motorsport, street-performance, and specialized applications, component selection follows the requirements of the complete brake system. The company was founded by Bill Wood in 1977 and is based in Camarillo, California, where its business focuses on designing and manufacturing disc brake systems, calipers, rotors, master cylinders, valves, fittings, and lines.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-8773\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\u003eWeight:\u003c\/strong\u003e 3.3 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner bearing specification:\u003c\/strong\u003e 370-3147 \/ A4 set (fitment reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter bearing specification:\u003c\/strong\u003e 370-1239 \/ A1 set (fitment reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDocumented solid-rotor arrangement:\u003c\/strong\u003e 0.35-inch solid rotor, mounted directly or with adapter 300-3307 as specified in DS-719\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eIdentify the 9-inch drum spindle on the specified 1965–1972 Mopar A-Body application before ordering.
