About this item

When a job demands the absolute upper limit of what a truck can do, the 2026 GMC Sierra 3500HD Denali is the answer. Towing a Flat deck? Horse Trailer? Home away from home? No problem!

The 6.6L Duramax turbo-diesel V8 is the powertrain choice for serious towing and hauling. Paired with an Allison 10-speed automatic transmission, the diesel engine delivers massive torque reserves that keep heavy trailers under control on climbs, and the standard exhaust brake helps manage descent without riding the service brakes. Whether the task is pulling a horse trailer, towing a large RV, or running a flatbed with equipment, the Sierra 3500HD Denali is rated to handle maximum-capacity heavy-duty work. An integrated trailer brake controller and the In-Vehicle Trailering App with pre-departure checklist, trailer tire pressure monitoring, and hitch guidance make the towing experience significantly more manageable.

Silver exterior, Black interior, and a cabin that genuinely competes with luxury sedans in terms of materials and technology. This is a heavy-duty work truck that treats the driver like royalty. The Denali trim inside this truck is thorough. Leather seats with 16-way power adjustment, heating, and ventilation. Heated second-row seats. Dual-zone automatic climate control. A 13.4-inch infotainment display with Google Built-In, wireless Apple CarPlay and Android Auto, and a Bose 12-speaker audio system. A 15-inch multicolor head-up display and a 12.3-inch digital driver information cluster put essential data in your field of vision without requiring you to look down. Power-retractable assist steps, a heated leather-wrapped steering wheel, and a rear camera mirror with auto-dimming complete a genuinely premium experience in a truck that also works harder than nearly anything else on the road.

Safety technology is comprehensive: enhanced automatic emergency braking, front pedestrian braking, lane keep assist, HD surround-view camera system, front and rear park assist, rear cross-traffic braking, and hill descent control. The GMC MultiPro tailgate offers six functional positions including a full-width load step and a work surface, and spray-in bedliner protection is included.

Financing solutions for personal and commercial buyers are available. Talk to us about getting this 1-ton truck working for you.
