The 1994 Chevrolet C/K 3500 series dually pickup truck came in standard, extended cab and crew cab configurations. It featured twin-wheels in the rear, hence the moniker “dually.” The Silverado was a top trim model through 1998 in a line that included the Cheyenne and Scottsdale trims. For 2001, Chevrolet abandoned the C/K designation and named all its light-duty trucks Silverado. Its near identical sibling is the GMC Sierra.
