Power and Performance
The awesome power boasted by this GMC truck for sale comes courtesy of two available engines. Standard on most trims is a 6.6-liter gasoline V8 capable of 401 horsepower and 464 lb-ft of torque. Available for most trims, and standard on the range-topping Denali Ultimate, is a Duramax® 6.6-liter turbo-diesel V8 engine that achieves 470 horsepower and 975 lb-ft of torque.
For off-roading, two trims are ideal. The AT4 comes with 20-inch wheels, skid plates, twin-tube Rancho® shocks, and available BFGoodrich® off-road tires. The AT4X goes a step further, introducing a factory-installed 1.5-inch suspension lift, Multimatic® DSSV dampers, and 35-inch Goodyear® Territory MT tires.

A properly equipped GMC Sierra 2500 HD with the available Crew Cab can tow up to 22,390 lbs. If you go this route, we recommend adding the ProGrade Trailering System, a suite of intelligent trailering technologies that streamline the hitching and towing process.
