Which GMC Sierra HD Trim is Right for Me?
The 2024 GMC Sierra HD features six trims to choose from, including the first-ever Sierra HD Denali Ultimate.
With a maximum towing capacity of up to 36,000 pounds on the Sierra HD 3500, this line of heavy duty trucks is more than capable of getting the job done. The base level Sierra HD Pro features Best-in-Class Heavy-Duty Cargo Bed Volume while the SLE trim adds an available 6.6-liter Duramax turbo diesel engine.
Those looking for the most trailering-assistance technologies in your truck's class should consider the SLT trim, while the AT4 brings the Off-Road Suspension Package and exclusive interior accents. The Sierra HD Denali boasts exclusive details as well, though in the form of authentic open-pore wood, a patterned aluminum trim and perforated leather seating surfaces.
The all-new Sierra HD Denali Ultimate is the quintessential heavy duty truck, coming standard with a standard 6.6-liter V8 Duramax turbo diesel engine, a signature Denali Vader Chrome Grille, an Ultimate Alpine Umber Interior with full-grain leather, open-pore paldao wood and 16-way power front seats with massage. If you're looking to maximize your Sierra HD capabilities, the Denali Ultimate is your best bet.
