In 1957 the light trucks received a new grille, while the design of medium and heavy duty trucks remained invariable. The new grille was standard white color, or extra-cost chromed. Cabs from this year received wrap-around rear windows for better visibility when backing. Only three engine options were available to light truck buyers, those being the basic Jobmaster and Thriftmaster 6-cylinder units or the 265 cubic inch Trademaster V8. However buyers did have a choice of four transmissions: the standard column 3-speed, a floor shifter heavy-duty 3-speed; a floor shifter 4-speed, or the column-mounted 4-speed Hydra-Matic.
