Championship points leader Australian Jack Brabham finished third in works entered Cooper T51, expanding his points lead, but not sufficiently to prevent a championship showdown with Moss and Ferrari driver Tony Brooks at the United States Grand Prix.

[citation needed] Tony Brooks made a good start but a piston failure eliminated him on the first lap.

Graham Hill and then Dan Gurney led, but lost their advantages through clumsy pit-stop action.

[citation needed] Moss continued to win at an average speed of 124 mph, a track record.

The combined efforts of Brabham, Moss, Maurice Trintignant, Bruce McLaren and Masten Gregory secured the Constructors' Championship for the Cooper Car Company.
