The Chevrolet Silverado, and its mechanically identical cousin, the GMC Sierra, is a series of full-size and heavy-duty pickup trucks manufactured by General Motors and 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 the C/K pickup truck from 1975 through 1998.
