GMC Sierra HD Trim Levels

GMC Sierra Heavy Duty Trim Levels

When your truck needs exceed the ability of even the most capable light-duty models, you need something bigger. You need the strength, durability, and accommodations of the prodigious 2020 GMC Sierra HD.

The GMC Sierra HD organizes features across five trim levels. Each one is powered by a powerful 6.6-liter V-8 engine (401 horsepower, 464 pound-feet of torque), but many Owings Mills shoppers choose the available 6.6-liter Duramax V-8. Paired with a 10-speed Allison® automatic transmission, this turbodiesel powerplant cranks out 445 horsepower and a stump-pulling 910 pound-feet of torque.
