2025 GMC Sierra 2500HD AT4X

Check out this one-owner 2025 GMC Sierra 2500HD AT4X Crew Cab, a heavy-duty truck that brings together serious diesel power, off-road capability, and first-class comfort. The Summit White exterior looks sharp against the gloss black front and rear bumpers, gloss black AT4X grille, red recovery hooks, and signature AT4X details. Inside, the Obsidian Rush leather interior gives this truck a premium look that separates it from an ordinary heavy-duty pickup. Under the hood is the highly sought-after 6.6-liter Duramax turbo-diesel V8 paired with the smooth Allison 10-speed automatic transmission. This proven combination gives you the power needed for towing, hauling, job-site work, and long highway trips. It is backed by a 3.42 rear axle ratio, 11,350-pound GVWR package, integrated trailer brake controller, in-vehicle trailering app, trailer sway control, and the gooseneck and fifth-wheel preparation package with stamped bed holes and a 7-pin trailer harness. The AT4X is built for more than pavement. It comes equipped with a rear electronic-locking differential, two-speed AutoTrac transfer case, heavy-duty air cleaner, digital variable steering assist, and a Traction Select System with Off-Road and Tow/Haul modes. The spray-on bedliner, GMC MultiPro tailgate, CornerStep rear bumper, LED cargo lighting, rear wheelhouse liners, and 120-volt outlets in the cab and bed make this Sierra ready for work, travel, or your next off-road trip. The Obsidian Rush interior is loaded with comfort, including 16-way power front bucket seats, heated and ventilated front seats, heated rear outboard seats, driver-seat and mirror memory, dual-zone climate control, a 60/40 folding rear bench with storage, premium floor liners, and a lockable center-console vault. Power-folding and extending heated trailer mirrors, remote keyless open and start, and the rear-window defogger add everyday convenience. Technology includes a 13.4-inch GMC Premium Infotainment touchscreen with Google built-in, navigation capability, Bluetooth, wireless Apple CarPlay, and wireless Android Auto. A 12.3-inch digital driver information center, SiriusXM capability, and OnStar services keep you connected. Safety equipment includes Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, HD Surround Vision, Front and Rear Park Assist, Rear Cross Traffic Alert, Trailer Side Blind Zone Alert, Safety Alert Seat, IntelliBeam headlights, and Following Distance Indicator.
