Vehicle Description
Built to get noticed and equipped to get to work, this lifted 2026 GMC Sierra 2500HD AT4 Crew Cab 4x4 brings serious diesel power to a sharp custom build. The Coastal Dune exterior, matching body-color details and gloss black accents give this GMC a distinctive look. A brand-new, professionally installed 3-inch Rough Country upper control arm kit, 20-inch gloss black Fuel Arc wheels and 37x12.50R20 Nitto Ridge Grappler tires complete the stance. Add the signature red AT4 recovery hooks, and you’ve got a truck worth seeing from every angle. The 6.6-liter Duramax turbo-diesel V8 pairs with a smooth Allison 10-speed automatic transmission, delivering the muscle you want for demanding work and weekends with a trailer. Four-wheel drive, a two-speed Autotrac transfer case and an automatic-locking rear differential provide a capable foundation. Off-Road and Tow/Haul modes, skid plates and a heavy-duty air cleaner round out an AT4 that’s ready for more than the daily commute. The trailering package, integrated trailer brake controller and Vehicle Trailering App help you prepare for towing, while Trailer Sway Control and Hill Start Assist add useful support on the road. Heated, power-folding and extending trailering mirrors with auto-dimming upper glass help with visibility alongside the truck. The GMC MultiPro Tailgate, CornerStep rear bumper, spray-on bedliner and LED cargo lighting make loading and accessing your gear easier. With 120-volt outlets in the cargo bed and instrument panel, this Sierra also brings convenient power to the jobsite or campsite. Inside, the Jet Black cabin with Kalahari accents gives this AT4 a look all its own. Heated and ventilated 10-way power front bucket seats, heated rear outboard seats and a heated steering wheel keep comfort high on the list. Driver-seat and mirror memory, dual-zone climate control and premium floor liners add everyday convenience, while the 60/40 folding rear bench with its storage package gives you room to organize your gear. Come settle into the driver’s seat and see how well this truck fits your day. The Premium GMC Infotainment System features a 13.4-inch touchscreen with Google built-in compatibility, navigation capability, Bluetooth and wireless Apple CarPlay and Android Auto for compatible phones. A 12.3-inch digital driver display and Bose premium sound system complete the cabin technology. HD Surround Vision, front and rear parking assistance, Rear Cross Traffic Alert and Trailer Side Blind Zone Alert provide helpful awareness around the truck. Automatic Emergency Braking, Forward Collision Alert, Lane Departure Warning and the Safety Alert Seat add further driver support.
