Pro
The Sierra 3500 HD Pro trim lays the groundwork for confident workdays with a standard 6.6L V8 gas engine paired to a smooth-shifting 10-speed automatic, engineered to put torque to the pavement with reassuring control. A Trailering Package with integrated Trailer Brake Controller and Trailering Mirrors supports daily hauling, while best-in-class HD cargo bed volume gives tools and materials room to ride. Inside, the Pro equips wireless Apple CarPlay® and Android Auto™ compatibility to streamline calls, mapping, and playlists without cords. The steel bed’s corner steps and multiple tie-downs help secure irregular loads, and the available Duramax 6.6L Turbo-Diesel V8, also matched with a 10-speed automatic, unlocks maximum confidence for long grades or high-elevation routes. Add the Traction Select System with Tow/Haul and available camera views to extend visibility backing into tight jobsites. Whether staging supplies before sunrise or towing equipment past La Junta, the Pro brings smart value and the fundamentals crews count on every day. Choose single rear wheel or dual rear wheel configurations to match payload goals, and use the MultiPro™ Tailgate for loading flexibility, makeshift work surfaces, and easier access, while durable flooring and practical storage help Pro clean up and reset for the next call.
SLE
SLE builds on the foundation with a technology suite that elevates command behind the wheel. A 13.4-inch center touchscreen integrates navigation, wireless Apple CarPlay® and Android Auto™ compatibility, and the In-Vehicle Trailering App, while a 12.3-inch digital Driver Information Center keeps performance data in view. The Traction Select System with Tow/Haul customizes responses for load or weather, and available up to 13 camera views, including Transparent Trailer and Hitch View, sharpen confidence when maneuvering in tight yards. Outside, 17-inch machined aluminum wheels set a refined stance, and the available MultiPro™ Tailgate with KICKER® audio turns the bed into a staging area after the work whistle. The X31 Off-Road Package adds twin-tube Rancho® shocks and skid plates for clients who split time between gravel sites and paved routes. For shoppers seeking robust comfort and everyday usability, the 2026 GMC Sierra 3500 HD SLE brings the right balance of intuitive tech, useful towing aids, and professional-grade durability. Opt for the Duramax 6.6L Turbo-Diesel V8 with a 10-speed automatic to maximize pulling power and engine braking on descents, and pair it with Trailering Mirrors and the Trailer Brake Controller to standardize control across your fleet while keeping the best-in-class bed ready for work.
SLT
SLT moves into premium comfort while staying fully job-focused. Ten-way power driver and front outboard passenger heated seats with lumbar support reduce fatigue across long-distance days, and the heated steering wheel keeps hands ready for precision inputs on winter mornings. The ProGrade® Trailering System with the In-Vehicle Trailering App brings customizable profiles, pre-departure checklists, and maintenance reminders into the 13.4-inch interface, helping reduce setup time and streamline repeat routes. Outside, 18-inch machined aluminum wheels with dark gray metallic accents deliver a confident stance, and the available MultiPro™ Tailgate with KICKER® audio doubles as a curbside briefing station. Available ventilated bucket seats with perforated leather appointments turn the cab into a mobile office, pairing with abundant charging to keep devices powered between appointments. At Wilcoxson GMC, our consultants often recommend SLT to growing businesses needing a refined truck that doesn’t compromise on control, thanks to the mix of trailering analytics, smart storage, and an interior that rewards the team after long shifts. Select the available Duramax 6.6L Turbo-Diesel V8 with a 10-speed automatic for torque on mountain passes, and layer in up to 13 available camera views to improve visibility when coupling, merging, and reversing amid lots of uneven, off-grid worksites.
AT4
AT4 is built for crews who split the week between pavement and rugged approaches. An Off-Road Suspension Package with twin-tube Rancho® shocks and skid plates steadies the chassis over washboard and rutted climbs, while exclusive 20-inch gloss-black aluminum wheels with available BFGoodrich® off-road tires provide confident traction. Inside, the exclusive Jet Black interior with Kalahari accents features heated and ventilated perforated front leather seating surfaces that help maintain focus in heat or cold. Up to 14 available camera views with HD Surround Vision reduce blind spots around equipment and trailers, and Adaptive Cruise Control with trailering helps keep gaps consistent on highway caravans. Add the available 15-inch Head-Up Display with an off-road inclinometer to monitor pitch and roll without losing sight of the trail. For teams who wrap a workday on dirt near Canon City and head to a client demo afterward, AT4’s bold stance and useful tech make transitions seamless at our showroom in Pueblo. Leverage the MultiPro™ Tailgate to stage plans or cut sheets at the site, and integrate the Trailering App’s checklists to keep teams aligned before departure, so equipment arrives secure, and schedules stay intact from first light to the last load back at base.
AT4X
AT4X raises the bar for remote jobsites and backcountry weekends. A factory-installed 1.5-inch suspension lift teams with Multimatic® DSSV dampers and a rear electronic-locking differential to maintain traction and composure across uneven rock shelves and washouts. Larger steel transfer case protection and a front aluminum skid plate help shield critical components, while 35-inch Goodyear® Territory MT tires bite into loose surfaces. Inside, the Obsidian Rush interior brings full-grain leather seating with technical-grain accents and authentic Vanta ash wood, and 16-way heated and ventilated power front seats with a massage feature restore energy between pushes. Choose the AT4X AEV Edition for stamped steel bumpers, added skid plates, and 18-inch Salta gloss-black wheels, or select the available Duramax 6.6L Turbo-Diesel V8 with a 10-speed automatic to add confident torque at altitude. For demanding builds that require capability and comfort, the 2026 GMC Sierra 3500 HD AT4X delivers professional-grade strength with a refined, trail-proven edge. Pair up to 14 available camera views with HD Surround Vision to scan obstacles near the rock rails and trailer corners, and add the 15-inch Head-Up Display with off-road inclinometer to track pitch and roll data at a glance while hands stay settled on the wheel for control.
Denali
Denali projects an unmistakable presence and rewards long routes with premium appointments. 20-inch Ultra-Bright machined aluminum wheels with bright chrome inserts set off the signature grille, while Denali-exclusive authentic wood, patterned aluminum trim, and Forge perforated leather seating surfaces elevate every commute and jobsite arrival. Twelve-way heated and ventilated power front seats deliver daylong support, and the available power sunroof adds an open-sky feel to high-country drives. Add the available Rear Camera Mirror for a clear, wide rearward view around cargo and tall items in the cab, and choose the available Duramax 6.6L Turbo-Diesel V8 with a 10-speed automatic for confident trailering in mountain wind and on steep grades. At Wilcoxson GMC, our team often guides clients toward Denali when the brand statement matters as much as the specification sheet, because its balance of technology, craftsmanship, and capability complements executive needs just as naturally as it supports demanding heavy-duty assignments. Tie it together with the 13.4-inch infotainment system and the In-Vehicle Trailering App, then layer in available up to 14 camera views with HD Surround Vision to help ease tight turns, while the MultiPro™ Tailgate transforms the bed into a versatile loading and presentation space for crews and clients alike on site.
Denali Ultimate
Denali Ultimate sits at the apex of heavy-duty luxury with intelligent strength built in. A signature Vader Chrome grille and exclusive 20-inch Ultra-Bright machined aluminum wheels with gloss-black inserts announce its presence, while illuminated power assist steps simplify entry once the day’s gear is loaded. Inside, the exclusive Alpine Umber interior surrounds with full-grain leather seating, authentic Paldao wood, and precise metal detailing, and 16-way power front seats with a massage feature restore energy on long-haul timelines. A 12-speaker Bose® Premium Series with Centerpoint® surround sound enriches podcasts and calls, and the MultiPro™ Tailgate Audio System by KICKER® turns the bed into a briefing hub. Powered by the Duramax 6.6L Turbo-Diesel V8 with a 10-speed automatic, Denali Ultimate is engineered for confident trailering, especially when paired with available auxiliary trailer camera options. When executive polish and uncompromising muscle must travel together, the 2026 GMC Sierra 3500 HD in Pueblo, Denali Ultimate makes every mile feel expertly managed. Cap it with the available 15-inch Head-Up Display and Rear Camera Mirror to maintain clear sightlines while towing tall equipment, and rely on the In-Vehicle Trailering App to store profiles and checklists that keep multi-stop days on time, organized, and stress-resistant too.
