Pro
For many shoppers, the Pro trim is the ideal way to step into a 3/4-ton truck that is built to earn its keep every day. The 2026 Sierra 2500 HD Pro features a standard 6.6L V8 gas engine mated to a 10-speed automatic transmission for smooth, confident power delivery under load. A Trailering Package, Trailering Mirrors, and an integrated Trailer Brake Controller come standard, so essential hardware is in place before the first hook-up. Best-in-class HD cargo bed volume and corner steps make loading, securing, and accessing materials simpler, while the available MultiPro™ Tailgate adds flexible configurations for staging tools or creating a stable work surface. Inside, Wireless Apple CarPlay® and wireless Android Auto™ compatibility keep maps, calls, and playlists within easy reach on the go. A durable, easy-to-clean cabin resists daily wear, and the Sierra HD’s robust frame and suspension tuning deliver stable ride quality when hauling equipment or building supplies. Optional camera views, including Hitch Guidance, build confidence during tight maneuvers. For tradespeople, fleet managers, and weekend tow owners who value durability, the Pro trim nails the fundamentals — straightforward power, dependable trailering gear, and practical tech that makes the daily routine more efficient.
SLE
The SLE trim layers in confidence-boosting tech and useful comforts that make every long day more productive. A 13.4-inch diagonal center touchscreen teams with a 12.3-inch digital Driver Information Center to present clearly organized menus, customizable data, and crisp graphics. Traction Select System with Tow/Haul mode optimizes throttle and shift calibrations for heavy loads, while 17-inch machined aluminum wheels offer a clean, purposeful look. Shoppers can add up to 13 camera views, including Transparent Trailer View, to simplify lane changes and parking lot navigation with a trailer attached. The available MultiPro™ Tailgate with optional MultiPro Tailgate Audio System by Kicker® is a jobsite favorite for quick loading or setting up a tailgate workstation. For light off-road travel or rough backroads, the available X31 Off-Road Package adds twin-tube Rancho® shocks and skid plates. This well-equipped trim speaks to drivers who want comfort and clarity without overcomplicating the truck. Whether commuting to jobsites near Clarkston, WA or setting off for a weekend tow, SLE balances the essentials with technology that simply works as promised.
SLT
SLT is the sweet spot for many owners who want premium comfort, elevated technology, and confident trailering capability without stepping into luxury pricing territory. It builds on SLE with 10-way power driver and front outboard passenger heated seats with lumbar, a heated steering wheel for cold mornings, and handsome 18-inch machined aluminum wheels with dark gray metallic accents. The ProGrade® Trailering System with In-Vehicle Trailering App delivers custom profiles, pre-departure checklists, and trailer diagnostics designed to streamline towing routines. For crews that spend long days in the seat, available 10-way power-adjustable heated and ventilated bucket seats with perforated leather appointments add upscale support and year-round comfort. Pair SLT with the available MultiPro™ Tailgate to simplify loading height transitions or turn the gate into a quick stand-up desk. The Sierra HD’s stout chassis and smooth-shifting 10-speed transmission keep energy in reserve for passing on grades or managing variable terrain. As a one-truck solution that suits workdays and family trips alike, SLT is a compelling choice — and our team at Lewiston Chevrolet GMC can help match the right configuration to your towing and payload needs.
AT4
AT4 blends the Sierra HD’s work-first attitude with trail credibility, so rough roads or muddy project sites feel like part of the plan. Exclusive Jet Black interior with Kalahari accents sets the tone, surrounding heated and ventilated perforated front leather seating surfaces with a premium, durable finish. The Off-Road Suspension Package with twin-tube Rancho® shocks and skid plates helps manage washboard surfaces and rock-strewn access roads, while exclusive 20-inch gloss-black aluminum wheels are ready for available BFGoodrich® off-road tires. Up to 14 available camera views, including HD Surround Vision, provide an extra set of eyes when cresting an off-camber trail or navigating tight staging areas with a trailer in tow. Available Adaptive Cruise Control with trailering adds a layer of calm during longer highway stretches, and an available 15-inch Head-Up Display with off-road inclinometer keeps attention on the path ahead. AT4 still offers the MultiPro™ Tailgate and extensive bed functionality, so the truck transitions smoothly from weekday duty to weekend adventure. For owners who demand capability on the clock and confidence off the grid, AT4 answers with upgrades that matter where the pavement ends.
AT4X
When the job takes you farther into the backcountry — or you want a truck that doesn’t flinch when the trail demands more — AT4X is the Sierra 2500 HD at its most adventurous. A factory-installed 1.5-inch suspension lift teams with Multimatic® DSSV dampers to manage big hits and small chatter alike, while a rear electronic-locking differential and robust skid plate protection — including a larger steel transfer case shield and front aluminum skid plate — fortify the driveline for demanding terrain. Factory 35-inch Goodyear® Territory MT tires provide serious bite with the control of a 3/4-ton chassis underneath. Inside, AT4X brings an Obsidian Rush interior with full-grain leather seating, technical-grain leather accents, and authentic Vanta ash wood trim, complemented by 16-way heated and ventilated power front seats with a massage feature. For owners who want a turn-key overland look, the available AT4X AEV Edition adds stamped steel bumpers, steering gear and transfer case skid plates, and distinctive 18-inch Salta gloss-black wheels. Add available Duramax® 6.6L Turbo-Diesel V8 power and the MultiPro™ Tailgate, and AT4X becomes a rugged tool that also serves as a refined mobile basecamp after the work is done.
Denali
Denali defines premium craftsmanship in a heavy-duty pickup, elevating the Sierra HD cabin and exterior with unmistakable style and comfort. Denali-exclusive authentic wood and patterned aluminum trim pair with Forge perforated leather seating surfaces to create an upscale, quiet workspace on the move. Standard 12-way heated and ventilated power front seats meet long-haul demands, while 20-inch Ultra-Bright machined aluminum wheels with bright chrome inserts add signature presence. Owners can opt for the Duramax® 6.6L Turbo-Diesel V8 with a 10-speed automatic transmission for confident torque, or choose thoughtful add-ons like a power sunroof and Rear Camera Mirror for day-to-day convenience. Advanced camera availability supports tight-quarters maneuvering with a trailer attached, and the MultiPro™ Tailgate remains an indispensable partner for loading bulky cargo. For drivers who need capability wrapped in sophistication, the 2026 GMC Sierra 2500 HD near Clarkston, WA makes Denali an excellent choice — full of technology that streamlines towing and road-trip comfort that makes every mile feel a class above. It’s professional grade, polished.
Denali Ultimate
Denali Ultimate takes the Sierra HD’s premium vision and perfects it with signature design and segment-leading amenities. Under the hood, the Duramax® 6.6L Turbo-Diesel V8 with a 10-speed automatic comes standard, balancing authoritative torque with confident control on grades and in headwinds. Outside, a signature Vader Chrome grille and exclusive 20-inch Ultra-Bright machined aluminum wheels with gloss-black inserts underscore Denali Ultimate’s presence. Step inside to an exclusive Alpine Umber interior featuring full-grain leather seating, authentic Paldao wood, and 16-way power front seats with massage — a true first-class setup that reduces fatigue on long tows. A 12-speaker Bose Premium Series with Centerpoint surround sound and illuminated power assist steps complete the sense of occasion, while the MultiPro Tailgate Audio System by Kicker® turns worksites or campsites into impromptu gathering spots. An available auxiliary trailer camera further enhances situational awareness.
