Greenlight 1:64 2019 Chevrolet Silverado Trail Boss, Red

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.

The heavy-duty trucks are referred to as "Silverado HD" and "Sierra HD", and as the Chevrolet Cheyenne in Mexico. Perennially one of the best-selling vehicles in the United States, almost 12 million Silverados have been sold since its introduction.

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, Sierra Grande, and High Sierra) as both model names and trim lines; 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 additional creature comfort features and design changes. Chevrolet's equivalent to the Denali trim level is the High Country Silverado which was introduced for the 2014 model year. In 2018, at the NTEA Work Truck Show in Indianapolis, IN, another new Silverado will be released, being the 4500, 5500 and 6500 Medium Duty Chassis Cabs; these vehicles will be exclusive to Chevrolet, as GMC has no plans to offer an equivalent. 

Chevrolet continued production of the third-generation Silverado 1500 for 2019, which was sold alongside the all-new, fourth-generation 2019 Chevrolet Silverado 1500. Renamed the Chevrolet Silverado LD ("LD" for Light Duty), production of the previous-generation truck moved from Fort Wayne, Indiana to Oshawa Car Assembly, Ontario, Canada. Only available in a Double Cab/Standard Box configuration, the Silverado LD ended production in December 2019.

The first-generation Chevrolet Silverado 1500 was sold alongside the second-generation Chevrolet Silverado 1500 for the 2007 model year as the Chevrolet Silverado 1500 Classic, and 2500 and 3500 versions of the truck were also sold alongside their successors, the Chevrolet Silverado 2500 and 3500. GMC also offered versions of their Sierra trucks as the Sierra Classic for 2007 as well, and will do the same for 2019, offering the predecessor generation model as the 2019 GMC Sierra 1500 Limited.
