ENGINEERED TO CONQUER

The Sierra Heavy Duty pickup truck delivers towing capacity in excess of 13,608 kg (30,000 lb.)1 of max towing capability. It’s built strong so you can tow strong with a larger drive shaft and rear axle that increases durability and strength. A bigger grille and engine fan improve engine cooling. Improved brakes and steering offer superior control.

FIRST-EVER AVAILABLE 10-SPEED ALLISON® TRANSMISSION

The available 6.6L Duramax® Turbo Diesel V8, which produces 445 horsepower and 910 lb.-ft. of torque, is paired with the all-new Allison® 10-speed automatic transmission – the first of its kind in the heavy-duty pickup segment. The all-new 10-speed transmission with closer gear spacing allows the engine to operate in an optimal range at all times with varying load and terrain conditions. This, combined with fortified components used throughout Sierra Heavy Duty’s driveline, provides maximum torque to the wheels at all times.


PROGRADE™ TRAILERING SYSTEM

An available system of intelligent technologies improves the trailering experience by adding functionality and convenience. An In-Vehicle Trailering App3, Smart Trailer integration and up to 15 unique class-leading2, high-definition camera views are available to help improve the hitching and towing experience.

INDUSTRY-FIRST TRANSPARENT TRAILER VIEW4

This available feature helps you see directly behind the trailer for improved visibility.

AVAILABLE REAR SIDE VIEW

This view shows the side of your truck, and if trailering, the front of the trailer. While towing with a conventional hitch trailer, rear facing side view cameras with available articulation functionality will automatically adjust the camera view in the direction the trailer is moving to provide maximum visibility.

AVAILABLE SMART TRAILER INTEGRATION

Innovative technology in partnership with ASA Electronics’ iN-Command® Control System allows you to easily control and monitor your trailer from inside the truck’s cabin. Before you arrive at your destination, you can adjust the trailer’s interior temperature, turn on the water heater and generator and check water and gas tank levels.

AVAILABLE BED VIEW

Let’s you see inside the truck bed to help with fifth-wheel hitching, and to check on cargo while driving.
