Unrivaled Performance for Any Job

The standard 6.6-liter V8 gas engine delivers 401 horsepower and 464 pound-feet of torque to make light work of heavy loads. For those needing maximum capability, the available 6.6-liter Duramax turbodiesel V8 produces a staggering 470 horsepower and 975 pound-feet of torque. Both pair with a robust Allison® 10-speed automatic transmission to put that power to the ground.
With the diesel powertrain, the GMC Sierra 3500 HD can tow up to 36,000 pounds when properly equipped. That's enough pulling power to confidently haul hefty equipment to job sites in Lancaster.
