Dealer Description

Commanding power meets premium craftsmanship in this 2021 GMC Sierra 2500HD Denali 4WD—a heavy-duty truck engineered for those who demand more from every drive. With 85,220 miles and a striking White exterior over a luxurious Jet Black leather interior, this Sierra Denali perfectly blends toughness and refinement. Under the hood lies the legendary Duramax 6.6L Turbo-Diesel V8 engine, B20-diesel compatible, delivering exceptional torque and performance for even the most challenging jobs. Paired with the Allison 10-speed automatic transmission, it ensures smooth, responsive shifting and incredible pulling power. Supporting this strength is the Pro Grade Trailering Package and Towing/Camper Package, making it ideal for heavy loads, trailers, or recreational applications. The Exhaust Brake feature adds confidence and control when descending steep grades. The X31 Off-Road Package gives this Denali serious off-road credibility thanks to upgraded suspension and rugged capability, while the GMC MultiPro Tailgate enhances versatility with multiple configurations for easier loading and worksite convenience. Inside, the Denali’s cabin exemplifies premium craftsmanship. Heated leather seating, a power driver’s seat, and refined materials create a comfortable, quiet haven from the road. The premium GMC Infotainment System with navigation features an 8" color touchscreen, seamlessly integrating connectivity and entertainment. The Driver Alert 1 and 2 Packages, Rear Parking Sensors, and Rear Camera Mirror with full camera display provide advanced technology for awareness and safety. You’ll also enjoy a multi-color 15" diagonal Head-Up Display, projecting key information right into your line of sight. The Denali Ultimate Package and Technology Package take this truck to the next level.
