The 2026 GMC Sierra HD delivers serious towing capability-up to 36,000 pounds on properly equipped 3500 HD models. That power comes from the available Duramax 6.6L Turbo-Diesel V8, which produces 470 horsepower and a massive 975 lb-ft of torque. The diesel includes an integrated exhaust brake to enhance control and reduce wear when hauling heavy loads.

Beyond raw numbers, GMC engineered advanced trailering-assistance technologies to make complex towing easier. The ProGrade Trailering System integrates camera views, diagnostics, and trailer profiles into one intuitive interface. With up to 14 available camera views-including the innovative Transparent Trailer View-you'll have confidence managing equipment, livestock, or recreational trailers.
