The Chevrolet Silverado, and its mechanically identical cousin, the GMC Sierra, are a series of full-size and heavy-duty pickup trucks manufactured by General Motors and introduced in 1998 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 1987 for its variant of the GMT400 platform trucks.
Although General Motors introduced its first pickup truck in 1930, the term "Silverado" was a designation used only to detail the trim for the Chevrolet C/K pickup trucks, Suburbans, and Tahoes from 1975 through 1999. GMC used a few variations of the "Sierra" name (e.g. Sierra, Sierra Classic, and High Sierra); however, Chevrolet still uses the CK and the CC in their current model codes.
The Chevrolet Silverado and GMC Sierra trucks have been essentially the same for their entire history. However, there are some trim and add-on option variations. Early models included variations in the engine and equipment, but the present differences are slight. The 1999 model year redesign included different grilles and interior trim, and certain features (e.g. Quadrasteer) were included at different times on the two trucks. The GMC Sierra has a luxury package known as "Denali" which adds tons of creature comfort features and design changes. Chevrolet's equivalent to the Denali trim level is the High Country Silverado which was introduced in the 2014 model year. In 2018, at the Work Truck Show, another new Silverado will be released, being the 4500 and 5500; these vehicles will be exclusive to Chevrolet, as GMC has no plans to offer a equivalent. GM webpage
The GMT800 Silverado/Sierra 1500 and 2500 (non Heavy Duty) (light pickup trucks) were released in August 1998 as 1999 models. The "classic" light-duty GMT400 C/K trucks were continued in production for that first year alongside the new models, and the Heavy-Duty GMT400 pickups (alongside the GMT400 SUVs) were continued through 2000, with the new GMT800 Silverado/Sierra HD (Heavy Duty) being introduced. A small refresh for 2003 models was introduced in 2002, bringing slight design changes and an upgrade to the audio and HVAC controls. The latter 2006 and 2007 GMT800 production units used the name Classic to denote the difference between the first and second generation trucks.
