The GMC Sierra is a full-size and heavy-duty pickup truck introduced in 1999, as the successor to the long-running Chevrolet C/K line. The Silverado name was taken from a trim level previously used on its predecessor, the Chevrolet C/K pickup truck from 1975 through 1998. General Motors continues to offer a GMC-badged variant of the Chevrolet full-size pickup under the GMC Sierra name, first used in 1988 for its variant of the GMT400 platform trucks. The GMC Sierras have been essentially the same for their entire history. There are some trim and option variations as well. Early models included variations in the engine and equipment, but the present differences are slight. The 1999 redesign included different grilles and interior trim, and certain features were included at different times.
