This AT4 elevates the standard with genuine truck capability. The Duramax diesel engine delivers the torque needed for heavy hauling, while the active transfer case and off-road suspension make it equally at home on challenging terrain. The integrated trailer brake controller and hitch guidance system take the guesswork out of towing, whether you're pulling a gooseneck trailer or fifth wheel.
Inside the cab, the AT4 Premium Plus Package creates a workspace that rivals luxury vehicles. The power sunroof floods the interior with light, while the Technology Package brings advanced driver assistance features including adaptive cruise control, lane departure warning, and automatic emergency braking. The heated and ventilated front seats with lumbar support keep you comfortable during long days, and the rear seats are heated for passengers along the ride.
Connectivity is seamless with the 15-inch head-up display, wireless phone projection, and GMC Connected Services. Whether you need directions, entertainment, or real-time vehicle information, everything displays clearly and operates intuitively. The multicolor display puts critical information exactly where you need it without distraction.
Safety and visibility are paramount on this truck. The HD surround vision system, automatic high-beam headlights, and trailer side blind zone alert keep you aware of your surroundings. Power-retractable assist steps with integrated LED lighting make entry and exit easier while adding functional elegance.
Every detail reflects AT4 craftsmanship. The 20-inch high-gloss black aluminum wheels, gloss black header grille, and smoked amber roof marker lamps combine form with function. The winter grille cover, rear wheelhouse liners, and power-retractable steps are designed for serious work in serious conditions.
