2026 GMC Sierra 2500HD Denali Ultimate

Get the Duramax power you need with the Denali Ultimate luxury you’ve been wanting in this one-owner 2026 GMC Sierra 2500HD Crew Cab 4x4. The hard-to-find Glacier White Tricoat finish is a standout feature, giving this GMC a rich, premium look that deserves to be seen in person. Matching body-color wheel-arch moldings and bumper details complement the chrome accents, while the exclusive Alpine Umber leather interior makes this Ultimate just as impressive when you open the door. The 6.6-liter Duramax turbo-diesel V8 pairs with a smooth 10-speed automatic transmission, bringing serious muscle to your workweek and towing plans. Four-wheel drive, a two-speed Autotrac transfer case, an automatic-locking rear differential and a 3.42 rear axle provide a capable foundation. The X31 Off-Road Package adds off-road suspension with Rancho twin-tube shocks, skid plates and Hill Descent Control. Dual alternators and heavy-duty dual batteries add useful equipment to this well-appointed diesel. The gooseneck and fifth-wheel prep package provides mounting provisions for compatible in-bed hitch equipment, along with capped bed openings and a bed-mounted 7-pin trailer connection. The ProGrade Trailering System includes Hitch Guidance with Hitch View and the In-Vehicle Trailering App to help with setup and preparation. An integrated trailer brake controller, exhaust brake, Trailer Sway Control and Hill Start Assist support your towing duties, while heated, power-folding and extending trailering mirrors help you see alongside the truck. Inside, the Alpine Umber leather gives this Denali Ultimate a distinctive, upscale feel. A power sunroof opens up the cabin, while a heated leather-wrapped steering wheel, heated rear outboard seats and dual-zone automatic climate control help keep everyone comfortable. Driver-seat and mirror memory, wireless charging, remote start and Adaptive Cruise Control add conveniences you’ll appreciate every day. The folding rear bench, seatback storage and under-seat storage help keep your gear organized without taking over the cabin. A 13.4-inch GMC touchscreen and 12.3-inch reconfigurable digital driver display keep information within easy reach and view. The Bed View Camera, front and rear parking assistance, Trailer Side Blind Zone Alert and Rear Cross Traffic Alert provide helpful awareness around the truck. Outside, the GMC MultiPro Tailgate, integrated bed steps, CornerStep rear bumper and LED cargo lighting make loading and accessing your gear easier.
