Certified 2024 Gmc Sierra 2500 HD AT4

The 2024 GMC Sierra 2500 4WD Crew Cab AT4 in Sterling Metallic is a commanding full-size pickup engineered for capability, comfort, and advanced technology. Its exterior is bold and rugged, featuring LED animated projector headlamps, LED fog lamps, corner-step rear bumper, power-folding heated trailer mirrors with auto-dimming, a GMC MultiPro tailgate, and a spray-on bedliner with AT4 branding. Red front recovery hooks, rear-window defogger, and premium wheel arch moldings emphasize its off-road readiness, while the power sunroof and retractable assist steps add convenience and style. Beneath the hood, the Sierra AT4 is powered by the Duramax 6.6L turbo-diesel engine paired with an Allison 10-speed automatic transmission, providing exceptional towing and hauling capability. An auto-locking rear differential, two-speed Autotrac transfer case, traction select system with off-road and tow-haul modes, and all-terrain tires ensure confidence in demanding driving conditions. Skid plates, a heavy-duty air cleaner, and StabiliTrak with trailer sway control further enhance the truck’s rugged performance, while a 220-amp alternator, 120V power outlets, and trailer brake controller support functionality on and off the road. Inside, the cabin balances utility and comfort with dual-zone climate control, 10-way power-adjustable front bucket seats, heated and ventilated front seats, heated rear outer seats, and driver seat and mirror memory. Premium floor liners, a wrapped and heated steering wheel, and 60/40 rear folding bench seats with storage package offer both protection and convenience. Connectivity and technology are highlighted by the premium GMC infotainment system with a 13.4-inch diagonal color touchscreen, Google built-in navigation, wireless Apple CarPlay and Android Auto, Bluetooth compatibility, a 12.3-inch digital driver information center, BOSE premium audio, remote start, rear seat reminder, and a three-year remote access plan with OnStar and Wi-Fi capability.

With available packages such as the AT4 Premium Plus, Technology Package, Gooseneck/5th Wheel Hitch, and dealer-installed options like body-color wheel arch moldings, the Sierra 2500 AT4 combines extreme capability with advanced comfort, technology, and towing readiness, making it an ideal choice for those who demand both performance and refinement from a heavy-duty truck.
