Specifications for a 1984 Chevy K20

by Christine Wheatley

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.

Engine and Transmission

The gasoline engines available on the 1984 Chevy K20 included a 4.8-liter in-line-six engine with 120 hp and 215 foot-pounds of torque, a 5.7-liter V-8 engine with 175 hp and 275 foot-pounds of torque, and a 5.7-liter V-8 engine with 160 hp and 260 foot-pounds of torque. The K20 also had two diesel engine options: a 6.2-liter V-8 diesel engine with 135 hp and 240 foot-pounds of torque and a 6.2-liter V-8 diesel with 148 hp and 246 foot-pounds of torque. Transmission options for the Chevy K20 consisted of a three-speed manual, a four-speed manual, a four-speed manual with overdrive, a three-speed automatic and a four-speed automatic.


With the 1984 model year came several changes to the Chevy K20's body. It received a new bi-level grill, and galvanized steel door panels served as a new rust-fighting feature. The basic dimensions of the K20 stayed the same from 1973 until 1987. It was available with two bed sizes: a 6-foot bed and an 8-foot bed. The wheelbase measured 117.5 inches on the 6-foot bed model and 131.5 inches on the 8-foot bed model; the total length measured 191.3 inches on the 6-foot bed model and 212 inches on the 8-foot bed model. All K20 trucks had a 62.7-inch width and a 73.9-inch height.

Trim Packages

Six different trim packages were offered on the 1984 Chevy K20. Custom, the base model trim, included white-painted bumpers and mirrors, standard painted hubcaps and no taillight or tailgate moldings. The next trim level was the Custom Deluxe, with a padded bench seat and arm rests, courtesy lights, a padded dashboard, sun visors and stainless-steel grill moldings.
