Description for 2025 GMC Sierra 2500HD AT4X Truck

The 2025 GMC Sierra 2500HD AT4X is designed to balance off-road capability with high-end technology and interior refinement, making it one of the most well-equipped heavy-duty trucks in the GMC lineup. Powered by a 6.6-liter V8 engine paired with a 10-speed automatic transmission and 4WD, this AT4X trim is tailored for challenging terrain and demanding workloads. Its 2-speed active transfer case and Hill Descent Control contribute to its off-road performance, while the Gooseneck/5th Wheel Prep Package enhances its towing utility.

Inside the crew cab, the Obsidian Rush interior combines luxury with function, featuring leather-appointed seats that are heated and ventilated in the front and heated in the outboard rear positions. The cabin includes a floor-mounted center console and premium floor liners with removable carpet inserts, emphasizing both durability and comfort. The Bose Premium Series 12-speaker system and a 15-inch multicolor head-up display elevate the in-cabin experience. A large navigation display and Wireless Phone Projection ensure intuitive connectivity, while features like keyless open and start, push-button ignition, and a universal home remote add daily convenience.

The truck is equipped with an array of safety and driver assistance features. These include HD Surround Vision, Rear Cross Traffic Alert, a Safety Alert Seat, and Trailer Side Blind Zone Alert. Ultrasonic front and rear park assist, a bed view camera with trailer camera provisions, and trailer tire pressure monitoring contribute to safer maneuvering and trailering. A rearview auto-dimming mirror with a built-in camera and LED smoked amber roof marker lamps further aid visibility and awareness.

Utility features are extensive. Multiple USB portsincluding charge-only and data ports inside the center consolesupport device connectivity. A 120-volt outlet in both the bed and instrument panel, LED cargo lighting, rear wheelhouse liners, and a spray-on bedliner with the GMC logo enhance worksite readiness. Remote start, wireless charging, a power sunroof, and a sliding rear window with defogger are included to support comfort in all climates.

The exterior is finished in Summit White with a Gloss Black header grille and grille insert bars, giving the AT4X a distinct and rugged appearance. Rain-sensing wipers, deep-tinted glass, and LED lighting systems round out its upscale yet functional design.

For those interested in vehicle return flexibility, the 2025 Sierra 2500HD AT4X is backed by the Walt Massey 3 Day Money Back Guarantee. To qualify, the vehicle must be returned to the original dealership within three business days of purchase, before 5 p.m. CST, in like-new condition and with fewer than 300 miles driven. Vehicles exceeding the 300-mile limit may still be returned, subject to a \$1.00 per mile fee for additional mileage.

This AT4X trim is suited for buyers seeking a high-capability heavy-duty pickup that doesn't compromise on technology, comfort, or advanced towing features.
