STORY
The Sierra 2500HD is GMC's three-quarter-ton heavy-duty pickup, engineered for higher payload and towing than the half-ton Sierra 1500. It is offered with gasoline V8s and the Duramax turbo-diesel V8 paired to the Allison transmission, a combination prized for heavy trailering. The truck shares its heavy-duty architecture with the Chevrolet Silverado 2500HD.
