    • Chevrolet produced its 1955 pickup trucks in two separate production series. The Advance Design trucks were built from 1947 until early 1955. Task Force trucks were built from 1955 until 1959. The trucks were manufactured in a wide variety of models and body styles. They were available as short-beds, flat-beds, platform and stake models. They were also built as fully-enclosed panel trucks, Suburban carry-alls and delivery models. The carry-alls had three rows of seats while the delivery models had front seats with rear storage space.


    • Chevy trucks for 1955 featured the standard Thriftmaster inline six-cylinder engine. It used a Rochester single-barrel downdraft carburetor or a Carter updraft type. The carburetors had manual chokes. The 235.5 cubic inch, overhead valve straight-six had a bore and stroke of 3.56 by 3.94 inches. Its compression ratio was 7.5:1 and it idled at 475 rpm. It produced 112 horsepower at 3,700 rpm with a maximum torque rating of 200 foot-pounds at 2,000 rpm.

The trucks had hydraulic piston shock absorbers. The semi-floating rear axle had a welded, pressed steel banjo housing. The pickups used a standard GM manual three-speed synchro-mesh transmission with the shifter mounted on the steering column. This arrangement was known as "three-on-the-tree." A heavy-duty three-speed Borg-Warner or a GM four-speed gearbox with a floor shifter was optional. The clutch was a dry, single-plate type with woven or molded asbestos on the plate's facings.
