[1] Given these model-year designations, "E series" has come to mean all Studebaker trucks built between 1955 and the end of all vehicle production in the US in December 1963.

[2] A new massive fiberglass grille appeared on the 1957-58 3E models, and was the last significant styling change made to these trucks.

For the 1958 and 59 model years, a stripped-down, low-cost Studebaker truck, called the Scotsman, was produced in addition to the Transtars, in 1/2 and 3/4-ton ratings.

In the last two model years a 97 hp (72 kW) 159 cu in (2.6 L) three-cylinder Detroit Diesel 3D-53 engine was offered in 1 and 1½-ton configurations (8E15 and 8E25).

Studebaker did not make the 4WD equipment themselves, but (in common with Chevrolet and GMC at the time) purchased the hardware from NAPCO (Northwestern Auto Parts Company).
