The first of the GMC Sierra generations included model years 1988-1998; the first gen was a version of the Chevrolet C/K truck. Succeeding the C/K was the first-generation Chevy Silverado for MY1999, again twinned with the now second-generation GMC Sierra. Around four years later, it received a facelift, which saw it through until a third-gen redesign of the GMC Sierra for the model years 2007-2013 arrived. Though there was never a major facelift, the GMC Sierra received changes from year to year, with a light refresh applied to the 2010 model year.
The fourth generation saw the light as a 2014 model with new EcoTec3 gas engines, a mild-hybrid system, and an eight-speed transmission being some of the highlights on select powertrains. It received a refresh for MY 2016, which was followed by a brand-new 2019 fifth generation, now with a turbocharged four-cylinder base engine and a diesel option.

By the time the MY2022 mid-cycle refresh rolled by, the 4.3L V6 was history, but little else changed on the engine front except higher towing capacities for the 2.7L gas and 3.0L diesel powertrains.
