{"product_id":"wilwood-270-11533","title":"Wilwood Front Hat-Mount Hub for Mopar A-Body Disc Spindles (1973–1976)","description":"\u003cp\u003eThe 1973–1976 Mopar A-Body disc-spindle application uses a hat-mounted rotor with this hub. Bearing references differ from the adapter-mount alternative, making the complete spindle interface an essential check. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-11533\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e One hub; the compatible rotor, rotor adapter or hat and its attachment hardware are selected for the complete conversion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHat retention:\u003c\/strong\u003e Three 1\/4-20 holes; Wilwood lists bolt kit 230-7032\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub closure and races:\u003c\/strong\u003e Manufacturer describes included bearing races and screw-on aluminum cap; confirm the supplied assembly and obtain the compatible bearings separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Hub - Hat Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition in the specified assembly:\u003c\/strong\u003e Front\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\u003eWheel mounting pattern(s):\u003c\/strong\u003e 5 x 4.50, 5 x 4.75 inches; separate from rotor or drive-flange attachment\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 mounting arrangement:\u003c\/strong\u003e Hat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct-page drawing references (inches):\u003c\/strong\u003e D = 2.619; H = 2.025; M = 3.730; N = 2.060; P = 3.140; Q = 0.250.
