Transtar was the model name given to the line of pickup trucks produced by the Studebaker Corporation of South Bend, Indiana, from 1956-1958 and 1960-1963 (although the last vehicles were sold as 1964 models). The name was used on most trucks in the Studebaker E-series, but not all. The Transtar name was first introduced for the 1956 (2E series) model year in 1/2-ton, 3/4-ton, 1-ton, 2-ton, and 2-ton heavy duty capacities. The three smaller models were available with factory-built pick-up bodies. The basic styling of these trucks dated back to the 1949 models, though they had received some styling and engineering changes in 1954 and 55. The Transtar name continued to be used on most of the 1957-58 3E series trucks, though a stripped-down Studebaker Scotsman model without the Transtar name
