• The Silverado name became a part of the Chevy truck lineup in the 1980s, when it was used to identify the high-trim C/K-series trucks. In 1999, Silverado became the official name for all full-size Chevy trucks. In 2005, the Silverado had three different sizes: 1500, 2500HD and 3500HD. Among these sizes were different bed and cab configurations that affected the body size of the truck. The Silverado was available in regular, extended or crew cab. The beds were either short- or long-bed.
