If it matters to heavy-duty pick-up owners, it matters to GMC. They engineered the New 2011 GMC Sierra 3500HD with durable, advanced technology that makes it the most powerful heavy-duty ever made. First they strengthened the available, proven Duramax 6.6 Liter Turbo Diesel V8 engine and Allison transmission to generate and earth-shaking 765 lbs.-ft. of torque and 397 horsepower, numbers no other full-sized pickup can match - plus towing capacities up to 21,700 lbs! Next, the strength was redesigned with a high-strength, fully boxed steel frame with the ability to handle more payload than any competitor - up to 6,635 lbs. Stop in and see why GMC is Professional Grade, and the others are not!
