Think of this truck as a professional grade tool for work, with the durability and versatility we''ve all come to expect from the GMC nameplate. GM says our Sierra 2500 Work Truck is tops in many categories, including gross vehicle weight and maximum towing capacity, which checks in at 16,700 pounds. And with extensive noise-reduction measures, it has one of the quietest interiors among heavy-duty trucks. Check out the Crew Cab and great interior! It's what's under the hood that separates the men from the boys among heavy-duty pickups. Most folks will get by just fine with this standard 6.0L gas V8 engine that uses variable valve timing to produce 353-horsepower and 373 ft-lbs of torque. Print this page and call us Now...
