Learn about the GMC Sierra 2500


The GMC Sierra 2500 HD is the middle child of GMC's full-size pickup line. Bigger and more powerful than the Sierra 1500, the HD excels at towing and hauling. This makes it a popular choice for construction crews, especially with its powerful diesel engine.

Available in double and crew cab configurations, with two box lengths, the Sierra HD can pull double duty as a family vehicle. While its appeal is undeniable, remember that even the best diesel engine is going to cost you at the pumps.
