ASSERT YOUR DOMINANCE
Engineered for the bold, the monstrous exterior of the Sierra Heavy Duty was built big so you can tow big. The Dual Path Air Induction System on the available 6.6L Duramax® Turbo-Diesel V8 engine draws dense, cool air through both the hood scoop and the large front grille to provide cooler induction air temperatures to help optimize horsepower and trailering performance.
PRIMARY GATE
Open the primary gate using the key fob’s power release from inside the truck or from the button on the gate. These same buttons can be used to lock the gate once closed. In both corners of the rear bumper, large footwells, lined with an anti-slip texture and sized for large boots, help make access to the cargo bed seamless. Standard on all Sierra Heavy Duty models.
TECH & SAFETY
This system of intelligent trailering technologies helps streamline the hitching and towing process with integrated tools that help you tow with confidence and control. Not available on Sierra HD Pro.
EXTERIOR THAT CONQUERS
The Sierra HD AT4 off-road pickup truck pairs powerful performance with a bold, athletic look, delivered by way of distinctive finishes and modern, precise detailing. The available Trailering Mirrors, available MultiPro Tailgate and standard Side Bed Step are just some of the many impressive highlights contributing to the 2023 Sierra Heavy Duty’s powerfully bold exterior.
