Chevy stepside
The C/K was Chevrolet and GMC's full-size pickup truck line from 1960 until 1998 in the United States, from 1965 to 1999 in Canada, from 1964 to 2001 in Brazil, and from 1975 to 1982 in Chile. The first Chevrolet pickup truck came out in 1924, though in-house designs did not appear until 1930. "C" indicated two-wheel drive and "K" indicated four-wheel drive. The aging C/K light-duty pickup truck was replaced with the Chevrolet Silveradoand GMC Sierra names in 1999 in the US and Canada, and 2001 in Brazil; the Chevrolet Silverado HD and GMC Sierra HD heavy-duty pickup trucks followed. Until this time, the names Silverado and Sierra were used to identify the trim level of th
e C/K trucks.
The 1960 model year introduced a new body style of light pick-up truck that featured many firsts. Most important of these were a drop-center ladder frame, allowing the cab to sit lower, and independent front suspension, giving an almost car-like ride in a truck. Also new for 1960 was a new designation system for trucks made by GM. Gone was the 3100, 3200, and 3600 designations for short 1/2, long 1/2 and 3/4-ton models. Instead, a new scheme would assign a 10, 20, or 30 for 1/2, 3/4, and 1-ton models. Since 1957, trucks were available from the factory as 4-wheel drive, and the new class scheme would make this known.
