The International Six-Speed Special was a 1-ton truck built by the International Harvester Corporation between 1928 and 1930 at the Springfield, Ohio plant in America.
International had not had a 1-ton truck in its line since the S of 1926. This gap was filled in 1928 with the “Six-Speed Special”. The new truck was similar to the ¾-ton Special Delivery, but it had a bigger frame and larger tires. Its most notable feature was an Eaton 2-speed rear axle which, when combined with the 3-speed transmission, gave a total of 6 forward speeds and 2 in reverse. The Six-Speed Special was an instant hit and over 14,000 were built the first year, accounting for about a third 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. In 1931 the B-2 replaced the Six-Speed Special.
