Vehicle Description
Premium luxury meets serious Duramax diesel power in this incredibly clean 2026 GMC Sierra 2500HD AT4X 4x4. Finished in the stunning Volcanic Red Tintcoat exterior paired with the exclusive Obsidian Rush leather interior only available on the AT4X, this GMC has the perfect combination of aggressive styling, heavy-duty capability, and first-class comfort. Whether you're looking for a truck that can tow with confidence, handle off-road adventures, or simply turn heads around Scottsdale, this Sierra AT4X delivers everything you'd expect from GMC's flagship off-road heavy-duty truck. Power comes from the legendary 6.6-liter Duramax Turbo-Diesel V8 engine backed by the smooth Allison 10-speed automatic transmission, giving you the strength to tackle demanding jobs with ease. Equipped with a rear electronic locking differential, 2-speed Autotrac transfer case, Traction Select System with Off-Road and Tow/Haul modes, heavy-duty air cleaner, 220-amp alternator, trailer brake controller, factory trailering package, Vehicle Trailering App, and the factory Gooseneck/5th Wheel Package with stamped bed holes and 7-pin trailer harness, this Sierra is built for serious towing and hauling. Add in the 3.42 rear axle ratio, integrated hitch package, Hill Start Assist, Trailer Sway Control, and cargo bed power outlet, and this truck is ready for work the day you drive it home. Step inside and you'll immediately see why the AT4X sits at the top of the Sierra lineup. The exclusive Obsidian Rush leather interior features premium 16-way power heated and ventilated front bucket seats, heated rear outboard seats, dual-zone automatic climate control, driver memory settings, premium floor liners, rear under-seat storage, and a spacious rear seat with a folding storage package. Technology is everywhere with GMC's massive 13.4-inch touchscreen featuring Google Built-In, wireless Apple CarPlay, wireless Android Auto, Bluetooth, factory navigation capability, SiriusXM, a 12.3-inch digital driver information center, remote keyless entry and start, plus OnStar Basics. Outside, the animated LED headlights, LED fog lamps, LED cargo lighting, power folding and extending heated trailer mirrors, red front recovery hooks, GMC MultiPro Tailgate, spray-on bedliner, and Volcanic Red Tintcoat finish give this Sierra a bold look that's impossible to ignore. Safety is just as impressive with Forward Collision Alert, Automatic Emergency Braking, Front Pedestrian Braking, Following Distance Indicator, Lane Departure Warning, IntelliBeam automatic high beams, HD Surround Vision, Front and Rear Park Assist, Rear Cross Traffic Alert, Trailer Side Blind Zone Alert, Safety Alert Seat, Teen Driver Mode, and Buckle to Drive.
