Chevrolet C/K (first generation)

The first generation of the Chevrolet and GMC C/K truck line was built by General Motors for the 1960 to 1966 model years, replacing the Task Force trucks that came before it. It was the first General Motors light truck designed on a dedicated truck platform rather than as a derivative of the A platform, and the range covered pickups, chassis-cab trucks and medium and heavy commercial trucks. The C and K letters came from a new GMC naming system in which C meant two-wheel drive and K meant four-wheel drive, which was offered from the factory for the first time instead of through outside converters. The frame changed to a drop-center design with the cab mounted seven inches lower, and independent front suspension replaced the beam axle, with coil springs taking over from torsion bars for 1963. Power came from inline-six engines, a GMC V6 and Chevrolet small-block V8s. The line also underpinned the fifth-generation Suburban and Carryall and was assembled at many plants in the United States, in Canada and in South America. The Action-Line second generation replaced it for 1967.
