2025 GMC SIERRA 1500 DENALI 4WD 6.2L V8 DENALI RESERVE TECHNOLOGY PACKAGE SUNROOF BLACK 22s THUNDERSTORM GRAY LANCASTER PA
This 2025 GMC Sierra 1500 Denali 4WD is powered by the 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission. Finished in Thunderstorm Gray, this is an exceptionally well-equipped Denali with the Denali Reserve Package, Technology Package, power sunroof, GMC MultiPro Power Steps, and upgraded black 22-inch wheels.
The 6.2L V8 produces 420 horsepower and 460 lb-ft of torque, making it the most powerful gas engine available in the Sierra 1500. It delivers strong naturally aspirated V8 power for passing, towing, and everyday driving, with the 10-speed automatic keeping the power smooth and responsive.
The Denali Reserve Package gives this truck the upscale equipment and appearance buyers expect from a premium Sierra. The Thunderstorm Gray exterior with black 22s is an especially sharp combination, while the signature Denali chrome grille and MultiPro Power Steps give it a distinctive look. The steps automatically deploy for easy cab access and tuck away when not needed.
Inside, you get Jet Black perforated leather with heated and ventilated front seats, heated rear outboard seats, wireless charging, Navigation, Bose premium audio, remote start, and a power sliding rear window. The power sunroof adds another desirable luxury feature.
The Technology Package is a major upgrade and includes a massive 15-inch Head-Up Display, HD Surround Vision, Bed View Camera, and Rear Camera Mirror. Together, these systems provide excellent visibility around the truck whether you're parking, backing into a tight spot, or working with a trailer.
It's properly equipped for towing as well with the Trailering Package, integrated trailer brake controller, Hitch Guidance with Hitch View, in-vehicle Trailering App, Trailer Camera Provisions, and Trailer Side Blind Zone Alert. An automatic locking rear differential provides additional traction when conditions get slippery.
The bed is protected by a GMC spray-in bedliner and includes LED cargo lighting and a 120-volt power outlet, with another 120-volt outlet inside the cab.
Mileage is a huge standout on this oneit's sitting an impressive 18,547 miles below the market average.
This is a killer Denali configuration: 6.2 V8, Reserve Package, Technology Package, sunroof, power steps, black 22s, advanced trailering cameras, and exceptionally low mileage.
