Used 2025 Gmc Sierra 1500 AT4

Built for drivers who want serious capability without sacrificing luxury, this 2025 GMC Sierra 1500 AT4 delivers rugged performance wrapped in upscale refinement. Under the hood, the 3.0L Duramax Turbo-Diesel pairs incredible torque and efficiency with a 2-speed AutoTrac 4WD system, auto-locking rear differential, skid plates, and an off-road suspension with factory 2" lift—ready for dirt, snow, or the jobsite. Inside, it’s all first-class. Perforated leather seating, heated and ventilated front seats, heated rear seats, a heated steering wheel, and dual-zone climate control make every drive comfortable. The tech is next-level with a massive 13.4" touchscreen, 12.3" digital driver display, 15" Head-Up Display, rear camera mirror, and Bose premium audio, all powered by Google Built-In with wireless Apple CarPlay and Android Auto. On the outside, the AT4 stance means business—Onyx Black paint, off-road high-clearance steps, all-terrain tires, front recovery hooks, spray-on bedliner, LED cargo lighting, and the ultra-versatile GMC MultiPro Tailgate. Add in trailer brake controller, adaptive cruise control, and GMC Pro Safety, and this truck is as smart as it is tough. The Sierra AT4 doesn’t just go anywhere—it does it in style.
