GMT400

The GMT400 Chevrolet K2500 Pickup introduced a new rounded full-size truck design for the 1988 model year in the U.S. market. It replaced the square-body truck and continued as Chevrolet’s 3/4-ton heavy-duty pickup through the early 1990s. This generation is the one reflected by the observed U.S. specification years through 1993.
