Chevrolet truck body styles have changed numerous times throughout history, with no single year marking a universal change. Significant redesigns and body style changes occurred in various years, depending on the generation and model of the truck. For example:

* Major overhauls: There were significant redesigns in the 1947, 1955, 1959, 1960, 1967, 1973, 1988, 1999, and 2007 model years, among others. These years saw substantial changes in the overall design and styling.

* Incremental changes: Many years saw smaller updates and revisions to existing body styles, rather than complete overhauls.
