About the GMC Sierra 2500HD

The GMC Sierra 2500HD adds an extra dimension to the 2500 franchise with extra power.  This 3/4 ton pickup truck tows 13,000 lbs. and comes in Work Truck, SLE, and SLT trims, just like the other rugged pickups in GMC's lineup.

The most noteworthy changes to the Sierra 2500HD so far came in 2007 with the introduction of a high-powered 6.0 L, 353 hp V8 engine with an option to upgrade to 365 hp.  This truck has a prominent grille, headlights, and a re-furbished interior.  Overall, GMC sees the potential for growth with the Sierra 2500HD and plans to capitalize in the coming years.
