Used 2024 Gmc Sierra AT4

This 2024 GMC Sierra 2500HD AT4 4WD in Titanium Rush Metallic is the truck buyers wait for factory-loaded and already upgraded. Powered by the legendary 6.6L Duramax V8 Turbo Diesel paired with a 10-Speed Automatic transmission, this AT4 delivers massive torque, serious towing authority, and aggressive road presence. Sitting on OEM black 22-inch wheels wrapped in 35-inch all-terrain tires, this truck has a mean, no-nonsense stance without sacrificing ride quality or reliability. This is not stock. This is turn-key AT4 done right. This is the Duramax AT4 buyers actually want already upgraded, properly equipped, and ready to work or flex the moment you take delivery. Ideal for contractors, heavy haulers, and buyers who want aggressive looks without aftermarket guesswork. Aggressive. Loaded. Diesel. AT4. No compromises.
