GMC Sierra
The GMC Sierra is a full-size pickup truck that served as the successor to the GMC C/K series. It is mechanically identical to the Chevrolet Silverado in light-duty (1500) and heavy-duty (2500 HD and 3500 HD) configurations.
It’s worth noting that the Sierra moniker was first used to designate the range-topping trim level for GMC models until 1988, when the first-gen GMC Sierra pickup truck entered the market.
First-Generation Sierra
The first-generation GMC was essentially a rebranded fourth-generation Chevrolet C/K pickup truck.
The first-gen Sierra rode on the GMT400 platform, which it shared with the fourth-gen Chevrolet C/K, first-gen Chevrolet Tahoe, eighth-gen Chevrolet Suburban, first-gen GMC Yukon, and first-gen Cadillac Escalade. Production took place at assembly plants throughout North America, including the GM Arlington plant in Texas, the GM Fort Wayne plant in Indiana, the GM Flint plant in Michigan, GM Janesville plant in Wisconsin, and the GM Oshawa plant in Canada.
For the 1995 model year, General Motors gave the first-gen Sierra a mid-cycle refresh that included revised exterior styling and the introduction of a suite of safety features.
The first-gen Sierra was available with a bevy of powerplant options across all configurations:
