Ground-Trembling V8

The Sierra HD’s base engine is a gasoline 6.6L V8 producing a thundering 401 hp and 437 lb-ft of torque. An Allison 10-speed automatic transmission is standard, featuring Auto Grade Braking to help the pickup truck decelerate when driving downhill. On the 3500 HD, the gasoline engine provides an impressive max payload rating of 4,571 lbs.

Alternatively, the pickup truck can be equipped with a 6.6L Duramax turbo-diesel V8, which prepares it to tow the heaviest trailers at the worksite. The Duramax engine churns out a monstrous 470 hp and 975 lb-ft of torque and comes linked to the standard transmission. When properly equipped, the diesel-powered 3500 HD tows a staggering 36,000 lbs.

Versatile Tailgate

Getting goods in and out of the pickup box is made easy with the standard locking tailgate, which swings down and opens flat. To make the truck bed even more accessible, you can opt for the available GMC MultiPro Tailgate, which offers six functions. These include the ability to be lowered all the way, fold into a box step, and fold out the inner gate to form a load stop. You can also fold the GMC MultiPro Tailgate into a workbench.

Excellent Build Quality

The Sierra HD is as tough as pickup trucks come, with both 2500 HD and 3500 HD models featuring high-strength steel frames with hydroformed front sections. The truck bed is made of rolled-formed steel to support heavy-duty hauling without deforming over the years. Additionally, the Sierra HD’s standard suspension package features durable shocks that are designed to provide comfort and remain rigid while handling heavy weights.

Smart Trailering Tech

To make your workday easier, the Sierra HD features multiple smart trailering technologies. For instance, 13 available camera views, such as a transparent trailer view and a bird’s-eye view, make trailering in urban areas convenient. The ProGrade Trailering System provides assistance when hitching the truck to a compatible trailer. Additionally, the In-Vehicle Trailering App offers a useful pre-departure checklist, trailer security alerts, and much more. You can access the app using the vehicle’s 13.4-inch touchscreen or on your smartphone.
