General Notes:

This table attempts to document the existence of all Studebaker truck models from 1930 to the end of production in 1964. The data in it were obtained from a number of sources. Information on 1930-36 trucks and the Army trucks built by Studebaker during World War II and the years afterward came primarily from articles in Turning Wheels by Fred Fox and Clell Ballard. Data on 1937-64 civilian truck production came from original Studebaker literature: data books, parts books, sales literature, service letters, service bulletins, and related factory materials. Many engine data came from contemporaneous sales literature, which is often printed before production begins. Other engines may have become available later in the model year. And of course, Studebaker had a reputation for being willing to build and equip trucks for a special order, even though they were not in the catalogue.

It should be noted that the information in these documents occasionally do not agree. Some literature was printed before production started, and may have included preliminary information that was later revised. In addition, some model, engine, and wheelbase combinations may have been available, but were not actually built. The reverse was also true on a number of occasions. Studebaker sometimes dropped a particular model due to low sales during the previous year, but then went ahead and built a small number anyway in response to a firm order.

Studebaker also offered a number of export-only models, and also continued to build for export orders some models that had been dropped from domestic catalogs. Such models would not be listed in domestic sales literature, and also wouldn’t necessarily be listed in data books or early printings of parts books. However, they usually would appear in later, multi-year parts books that were printed after the end of the relevant model years.

Studebaker used hyphens in some model numbers, but these have been deleted in this table to conserve space.
