The C/K was the name for Chevrolet's full-size pickup truck line from 1962 until 1998 and GMC's full-size pickup line from 1962-1988. The first Chevrolet pickup truck appeared in 1924, though in-house designs did not appear until 1930. "C" trucks had two-wheel drive while "K" models had four-wheel drive. The C/K light-duty pickup was replaced with the GMC Sierra in 1988 and the Chevrolet Silverado in 1999; the Chevrolet Silverado HD and GMC Sierra HD heavy-duty pickups followed in 2001.

1975 introduced two important names as trim lines, Silverado for Chevrolet and Sierra for GMC. In order, the new trim lines for Chevrolet and GMC were:

> Custom Deluxe/Sierra — base model. Rubber floor mat, cloth seats, no lower door panel carpet, no headliner, manual door locks/windows.
>Scottsdale/Sierra Grande — chrome trim, everything the previous trim level had
>Cheyenne/High Sierra — brushed aluminum interior accents, vynl seats, chrome trim, carpet, air conditioning, headliner, more sound deadening/insulation (inside door panels, in the headliner, etc.).
>Silverado/Sierra Classic — wood (brushed aluminum on 1981-87) interior accents, everything the previous trim level had, more chrome (i.e. bumpers and mirrors), tilt wheel, power doors/windows, and cruise control. The "Country Cadillac."
(Rhapsodic note: The CHevy/GMC trucks are called C/K 10,20,30 I think what GM did with there trucks and vans was place the trim level on the vehicle instead of C/K same truck just a different trim is labeled on its fenders)
