The GMC 2 1/2 ton 6x6 Trucked the CCKW was named according the GMC production nomenclature of the time. CCKW was assigned by GMC using their standard system as follows: C = designed in 1941, C = standard cab, K = front wheel drive, W = rear wheel drive. Production of the CCKW began in 1941 and ended in 1945, with a total of 562,750 manufactured, one of the most commonly used vehicle's in World War II. It remained in service until 1956, including use in the Korean War.
CCKWs were originally fitted with a sheet metal cab (called the "closed cab"), but after July 1943 a canvas cab was substituted to save steel and reduce shipping volume (the "open cab"). Both long (164 in. CCKW-353) and short (145 in. CCKW-352) wheelbase models were produced, as well as numerous variations on body style and running gear.
The CCKW had the 92hp GMC 270 6 cal. engine. The weight was 10,350 lbs. (CCKW-352) or 11,250 lbs. (CCKW-353). Width was 86.25 inches and height 93 inches. The basic cargo truck had folding troop seats in the bed
The CCKW 352 with a short cargo bed was intended as an artillery prime mover for 75mm and 105mm howitzers.
The popular name for the CCKW's in general was the 'Duece and a Half', or 'Jimmy', these were the standard medium truck of the U.S. for most of WWII and the only vehicle made in greater numbers was that of the Jeep.
