The Chevrolet K20, part of Chevy's C/K truck line, was a full-size pickup truck produced in the United States from 1960 until 1999. On the Chevy C/K trucks, the C denoted the two-wheel drive models while the K denoted the four-wheel drive models. The K20 name referred to the three-quarter ton, four-wheel-drive Chevy truck model. New features on the 1984 K20 included a redesigned front end and some minor body improvements.
