About GMC Sierra

The GMC Sierra was introduced to the U.S. market in the 1930's as a full sized utility truck and famously used by the United States Army for marine training. As the luxury version of the Silverado, Sierra car parts were retooled for more driver and passenger comfort. Differing model variations include the light-duty Sierra 1500, the half-ton, the SS, and a hybrid model in 2000. Its rugged body design fused with a powerful engine allowed the Sierra to accomplish what other trucks typically could not. Whether it's for every day commuting or carrying heavy loads, Sierra body parts are built for reliability and longevity.
