This 2026 Sierra 2500HD Denali arrives in striking Silver, finished with a professional appearance that commands attention. The Duramax turbodiesel engine delivers the torque and power you need for serious work, while the 10-speed automatic transmission and 4WD system provide confidence on any terrain. With just five miles on the odometer, this truck is essentially brand new and ready for its first owner.

Inside, the Denali Reserve trim elevates comfort with forged perforated leather-appointed front seats, both heated and ventilated for your convenience. The 12-way power driver seat with lumbar support ensures you stay comfortable during long drives. Heated rear seats extend that comfort to your passengers, while the power sunroof adds an open-air dimension to the cabin experience.

Technology surrounds you in this Sierra. The 15-inch head-up display keeps essential information visible without diverting your attention from the road. Apple CarPlay and Android Auto keep your devices seamlessly integrated, while wireless charging and phone projection eliminate the need for cables. The Bose premium audio system delivers quality sound whether you're streaming SiriusXM or your personal music library.

Safety and convenience features work together to protect you and make operation easier. The HD Surround Vision system with bed view camera and trailer camera provisions—plus trailer side blind zone alert—provides visibility you can trust. Automatic emergency braking, forward collision alert, and front pedestrian braking add layers of protection. Ultrasonic front and rear park assist helps in tight spots, while the hitch guidance system with in-vehicle trailering app takes the guesswork out of towing.

The truck's exterior reflects its Denali status with the signature Chrome grille, LED smoked amber roof marker lamps, and power-retractable assist steps with bright LED accents. The spray-on pickup bedliner with GMC logo provides practical protection for cargo, while the 20-inch ultra bright machined wheels complete the refined appearance.
