The Ford Model AA was a series of heavy duty early trucks introduced in 1928. The Model AA used the same 3.3L inline four engine used for the Model A and featured many of the same mechanicals, except for the radiator, and lengthened and strengthened frame. The Model AA was offered on two wheelbase lengths, and in a variety of body styles for a wide range of uses. Production of the Ford Model AA ended in 1932, and was replaced by the Model BB.
