The 2024 GMC Sierra 3500 HD is built for serious hauling. It comes standard with a 401-hp 6.6L V-8 gas engine paired with a 10-speed automatic transmission. If you need maximum capability, the available 6.6L Duramax turbo-diesel V-8 delivers 470 horsepower and 975 pound-feet of torque-and enables the truck's impressive 36,000-pound maximum towing capacity.

The Sierra 3500 HD stands out for its refined, responsive performance and better agility than other heavy-duty competitors. You can configure it with a single- or dual-rear-wheel (dually) axle. Trim options like AT4 and AT4X offer off-road suspension and locking rear differentials; the AT4X AEV adds reinforced bumpers and winch capability.
