This 2021 GMC Sierra 2500HD Denali Crew Cab is more than a heavy-duty truck, it's a bold statement of power, refinement, and pure capability. Coated in eye-catching Pacific Blue Metallic and riding high on polished 20" aluminum wheels, it commands attention the moment it rolls into view. Whether you're towing, trailering, or tackling backcountry terrain, this Denali stands ready with serious strength under the hood and high-end comfort in the cabin.
At its core, the legendary Duramax 6.6L Turbo-Diesel V8 engine teams up with the precision-tuned Allison 10-speed automatic transmission to deliver relentless torque and smooth shifts under load. With the X31 Off-Road Suspension Package, Rancho shocks, skid plates, and a 2-speed Autotrac transfer case, it's engineered to handle everything from deep snow to rutted jobsite roads without hesitation. And thanks to the gooseneck/5th wheel prep and integrated trailer brake controller, it's ready to pull serious weight, up to 11,300lbs with confidence and control.
But this truck isn't just brawn. It's loaded with brains, too. Step inside and you're surrounded by premium black leather, a heated and ventilated 10-way power driver's seat, dual-zone climate control, and an 8" HD touchscreen with navigation, Apple CarPlay, Android Auto, and wireless charging. A Bose premium sound system fills the cabin with clarity, while the Multicolor Head-Up Display keeps your focus on the road ahead. From the HD Surround Vision camera system to lane change alert and forward collision warning, this truck is packed with safety tech to back up its muscle.
Denali details like chrome assist steps, a power-sliding rear window, power-folding trailer mirrors, and LED signature lighting elevate its appearance and function alike. And when the job is done, features like keyless open and start, remote start, and the signature GMC MultiPro Tailgate make everyday use effortless.
This Sierra 2500HD Denali isn't just ready for your next challenge, its built to make you look good while you conquer it.
