Sierra Heavy Duty delivers meaningful choice under the hood.

For maximum torque and long-haul confidence, the available Duramax® 6.6L Turbo-Diesel V8 produces 470 horsepower and 975 lb.-ft. of torque, teamed with a 10-speed automatic that keeps the diesel in its sweet spot on grades and during highway passing. With the diesel, an available integrated exhaust brake adds control on descents, reducing pedal work and heat in the braking system. The driveline is designed to support serious trailering, and when properly equipped, Sierra HD models offer exceptional tow ratings—up to 36,000 pounds is available on 3500 HD. Sierra 2500 HD configurations deliver the robust pulling power customers expect in a heavy-duty workhorse, alongside thoughtful features like Tow/Haul mode, Trailering App checklists, and available Adaptive Cruise Control with trailering.
