1930 International Six-Speed Special Truck

The International Six-Speed Special was a 1-ton truck built by the International Harvester Corporation between 1928 and 1930 in Springfield, Ohio. International had not had a 1-ton truck in its line since the "S" model of 1926. This gap was filled in 1928 with the "Six-Speed Special". The new truck was like the ¾-ton Special Delivery, but it had a bigger frame and larger tires.

The most notable feature of the Six-Speed Special was the Eaton 2-speed rear axle which, when combined with the 3-speed transmission, gave a total of 6 forward gears and 2 in reverse. The Six-Speed Special was an instant hit and more than 14,000 trucks were built the first year, accounting for about 40 percent of International's total production for the year. The Six-Speed Special was moved by the underpowered but economical Waukesha XA L-head 4-cylinder engine. It had a top speed of 35 miles-per-hour.
