Trim Levels (Exterior)
The 2026 GMC Sierra 2500HD is offered in several trims, each with its distinct personality and features. The entry-level Pro trim introduces an efficient yet powerful build and Best-in-Class cargo volume, perfect for those looking for a reliable workhorse.
The SLE and SLT trims build upon this with more sophisticated elements such as 18” machined aluminum wheels, chrome accents, and interior upgrades.
The off-road-ready AT4 trim brings a rugged design with features like skid plates, exclusive 20” wheels housing all-terrain tires, and a more aggressive stance, while the AT4X pushes it even further.
With a 1.5” factory lift, steel transfer case, 35” MT tires, and more luxurious interior, it gives you both rugged and refined details.
At the top, the Denali trim exudes elegance with premium finishes, high-end leather seating, and cutting-edge tech, while the Denali Ultimate goes above and beyond. Its premium 22” wheels, signature Vader Chrome grille, and features like power-retractable running boards hint at the indulgence within. Each trim offers unique style, all contributing to the truck's commanding road presence.
Engine (Power)
The 2026 GMC Sierra 2500HD offers 2 brawny engine options to cater to varying needs for power and efficiency.
The 6.6L V8 gas engine delivers a remarkable balance of performance and fuel efficiency with 401 hp and 464 lbs.-ft. of torque, perfect for daily tasks and occasional heavy-duty work.
For more muscle, the 6.6L Duramax® Turbo-Diesel V8 engine steps up the game, delivering an extraordinary 470 hp and 975 lbs.-ft. of torque, ensuring that no job is too demanding.
