About: Chevrolet C/K (fourth generation)

The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2002 model years, this generation is the final version of the C/K model line. The C/K nomenclature itself became exclusive to Chevrolet, with the GMC division applying the GMC Sierra nameplate across its entire full-size pickup truck line. Internally codenamed the GMT400 platform, the fourth generation C/K was not given a word moniker (i.e., "Rounded-Line series"). After its production, the model line would informally become known by the public as the "OBS" (Old Body Style), in reference to its GMT800 successor.
