Pro
The Pro trim is engineered to make the foundation strong, so your most important tools ride with confidence in the 2026 GMC Sierra 2500 HD. A 6.6L gas V8 and 10-speed automatic team up for steady low-end response and smooth acceleration under load. Standard Trailering Mirrors, a Trailer Brake Controller, and a robust Trailering Package simplify setup, while best-in-class HD cargo bed volume gives you the room to stage materials efficiently. Step into the cab, and daily tasks get easier with wireless Apple CarPlay® and wireless Android Auto™ compatibility for hands-free calls and navigation. Add the available Duramax® 6.6L Turbo-Diesel V,8 and you unlock exceptional torque for fifth-wheel or gooseneck work, plus reassuring engine braking on long grades. Available Adaptive Cruise Control with trailering helps reduce fatigue on extended runs. The frame feels stout, steering is direct, and braking components are tuned for consistent pedal feel. For crews who want straight-to-business utility, the Pro trim brings the right foundation—capable, connected, and ready to scale with your demands as jobs grow more complex.
SLE
SLE builds on work-first fundamentals with the kind of modern tech and comfort that help you stay in control the whole day. Inside, a 13.4-inch center touchscreen pairs with a 12.3-inch digital Driver Information Center, so critical truck and trailering data are easy to read at a glance. The Traction Select System with Tow/Haul mode calibrates shifting and throttle response to suit your load, while available up to 13 camera views—highlighted by Transparent Trailer View—streamline hookups and lane changes with confidence. SLE also offers the available MultiPro™ Tailgate and the MultiPro Tailgate Audio System by Kicker® to bring new bed access flexibility and site-ready entertainment. Beyond screens and systems, the cabin improves everyday comfort with intelligently placed storage and supportive seating that still feels durable. You can further upgrade capability with the available X31 Off-Road Package featuring twin-tube Rancho® shocks and skid plates for added underbody protection. At Alpha GMC, we recommend SLE to drivers who want a technology-forward cockpit without compromising the clean, professional look and disciplined capability that define Sierra HD.

AT4
When the route involves dirt ruts, washed gravel, or a surprise mud section, AT4 transforms confidence into your everyday standard. The Off-Road Suspension Package with twin-tube Rancho® shocks and skid plates adds control and underbody protection, while available BFGoodrich® off-road tires enhance bite in loose terrain. Inside, you’ll find an exclusive Jet Black interior with Kalahari accents and heated and ventilated perforated front leather seating surfaces that keep posture and temperature dialed in.

Add the available MultiPro™ Tailgate to streamline cargo management when adventure and work converge in a single long day.
AT4X
AT4X is the most assertive off-road expression in the lineup—factory-developed and ready to hit the trail the moment you take the keys. A 1.5-inch suspension lift, Multimatic® DSSV dampers, a rear electronic-locking differential, a larger steel transfer case skid plate, and a front aluminum skid plate compose a hardware suite designed for control and durability. 35-inch Goodyear® Territory MT tires increase ground clearance and widen your footprint for confident traction. Inside, the Obsidian Rush interior features full-grain leather with technical-grain leather accents and authentic Vanta ash wood, capped by 16-way heated and ventilated power front seats with a massage feature. The 2026 GMC Sierra 2500 HD becomes a trusted partner on steep grades, rocky switchbacks, and snowy access roads, while remaining ergonomic and quiet on the highway. Equip the available AT4X AEV Edition for stamped steel bumpers, additional skid plates for the steering gear and the transfer case, and 18-inch Salta gloss-black wheels. With available Duramax® 6.6L Turbo-Diesel V8 power, AT4X pairs premium comfort with serious trail authority.
Denali
Where capability meets craftsmanship, Denali delivers a luxury-forward environment without stepping back from the heavy-duty mission. Denali-exclusive authentic wood and patterned aluminum trim elevate the cabin, while Forge perforated leather seating surfaces and 12-way heated and ventilated power front seats bring first-class comfort to long workdays and weekend escapes. Outside, 20-inch Ultra-Bright machined aluminum wheels with bright chrome inserts underscore Denali’s premium stance. The 2026 GMC Sierra 2500 HD integrates advanced assistance like an available Rear Camera Mirror for a full-width view behind the truck, and an available power sunroof that brightens the cabin.
