Description for 2025 GMC Sierra 2500HD AT4 Truck

The 2025 GMC Sierra 2500HD AT4 blends off-road capability with premium appointments and advanced technology, making it a well-equipped heavy-duty truck for drivers who demand durability without sacrificing interior refinement or modern convenience.

Powering the Sierra 2500HD AT4 is a 6.6-liter Duramax V8 turbodiesel engine mated to a 10-speed automatic transmission. This powertrain is designed for high torque output, supporting serious towing and hauling demands. The inclusion of a 2-speed active transfer case and the X31 Off-Road Package further enhances its performance in rugged conditions. The package adds off-road suspension, hill descent control, skid plates, and unique off-road tuning, supporting traction and control in challenging environments.

The AT4 trim emphasizes upscale ruggedness with exterior features like the gloss black header grille and smoked amber roof marker lamps. The off-road high clearance steps provide practical assistance while contributing to its aggressive stance. Integrated trailer camera provisions, HD Surround Vision, and the Trailer Side Blind Zone Alert bolster towing safety and maneuverability, while the Gooseneck/5th Wheel Prep Package readies the truck for heavy-duty trailer work. Additional features like LED cargo area lighting, a spray-on bedliner with GMC logo, and a 120-volt bed-mounted outlet add to the trucks overall utility.

Inside, the cabin offers a premium environment with Jet Black leather upholstery accented by Kalahari trim. Heated and ventilated front seats, heated second-row outboard seats, and a floor-mounted center console underscore comfort and practicality. The AT4 Premium Plus Package includes advanced tech such as a multicolor 15-inch diagonal head-up display, wireless charging, and a Bose premium 7-speaker sound system. The truck is also equipped with wireless Apple CarPlay and Android Auto via wireless phone projection for seamless connectivity.

Convenience and safety technologies are extensive. Keyless open and start, push-button ignition, a power sunroof, power sliding rear window, rain-sensing wipers, and remote start all come standard. The Sierra is equipped with a suite of driver assistance technologies including rear cross traffic alert, ultrasonic front and rear park assist, a safety alert seat, and a rearview auto-dimming camera mirror. The Universal Home Remote and SiriusXM with 360L add to everyday usability.

Also included are premium liners for both the front and rear with removable carpet inserts, multiple USB ports throughout the cabin, and 120-volt power outlets at the instrument panel and bed for added versatility.

As with all vehicles sold by Walt Massey, this truck is backed by the Walt Massey 3 Day Money Back Guarantee.
