The only two examples built in 1935, the SSJ Speedsters sported a lightweight open-roadster body produced by Central Manufacturing Company, an Auburn subsidiary in Connersville, Indiana. One of them belonged to the actor Gary Cooper, the other one was lent by the company to actor Clark Gable, who already owned a Duesenberg J.

At the rear, the SSJ sported an external spare tire and smaller "later-style" round taillights. The external exhaust pipes sprouting out of the hood were an indication it was the "supercharged" version, but these were optional on J models as well.
