Seller's Comments

Powered by the legendary 6.6L Duramax Turbo-Diesel V8 and paired with an Allison 10-speed automatic transmission, this Sierra 2500HD AT4X is engineered for demanding towing, hauling, work, and adventure. The AT4X combines GMC's heavy-duty capability with a premium, off-road-inspired design. Four-wheel drive provides confident traction when conditions get challenging, while the Sierra's heavy-duty chassis and Duramax diesel power make it an excellent choice for towing fifth wheels, travel trailers, equipment, boats, and other substantial loads. Under the hood, the 6.6L L5P Duramax Turbo-Diesel V8 delivers the torque and pulling power expected from a Sierra HD. The Allison 10-speed automatic transmission helps put that power to the ground smoothly and efficiently, making this truck equally capable on the highway, at the job site, or backing a trailer into camp. Inside, the AT4X provides an upscale cabin designed for both work and long-distance travel. The spacious Crew Cab offers excellent passenger room, while GMC's advanced technology and premium appointments create a comfortable environment for daily driving and extended towing trips. The Sierra 2500HD also offers advanced trailering technology and driver-assistance features designed to make towing and maneuvering a large truck more manageable.
