The Chevrolet Silverado from Chevrolet (along with its GMC counterpart, the GMC Sierra), is the latest line of full-size pickup trucks from General Motors. GMC's C/K used the "Sierra" as the higher-level trim designation on its vehicles up until 1988. In 1988, GMC decided to use the "Sierra" name on all GMC pickup trucks, though the "C/K" nomenclature was continued through 1999.

The HD variant is a heavy-duty light truck. It is a strengthened version of the Silverado/Sierra light-duty, and is available in the 1500HD, 2500HD, and 3500 models.
