History
The Silverado nameplate made its debut for the 1975 model year, becoming the top trim level on all Chevrolet C/K trucks,[3] slotted above Custom Deluxe, Scottsdale, and Cheyenne. At the same time, GMC C/K trucks used variations of the Sierra name (Sierra, Sierra Classic, Sierra Grande, and High Sierra). Today, Chevrolet still uses the CK and the CC in their current model codes to denote a 2-wheel rear drive (CC), or a four-wheel drive (CK).[4]
For the 1988 GMT400 model architecture, Chevrolet retained the C/K model nomenclature, with GMC branding its full-size line as Sierras. While sharing chassis and bodies, the model chronology of the Silverado and Sierra are different, with five generations of the Sierra and four of the Silverado.
In 2018, at the NTEA Work Truck Show in Indianapolis, IN, Chevrolet unveiled the first medium-duty Silverado, expanding the model line to a 4500, 5500, and 6500 chassis cab. Largely the successor to the 2003-2010 GMT560 chassis, the medium-duty truck is exclusive to Chevrolet, with no plans for an equivalent GMC version. Instead, International would sell the Silverado Medium Duty as a rebadged counterpart, called the "CV".
