The 2026 GMC Sierra 2500 HD gives you the uncompromising bones of a heavy-duty truck with the everyday usability you want.

Inside, a 13.4-inch diagonal center touchscreen and a 12.3-inch diagonal digital Driver Information Center put critical data and infotainment right where you need it. The Traction Select System with Tow/Haul mode optimizes performance for changing conditions, and 17-inch machined aluminum wheels add a clean, durable look.

You can also add the MultiPro™ Tailgate for flexible bed access and the available MultiPro Tailgate Audio System by Kicker® to turn the tailgate into a rolling command center for work or play. Consider the available X31 Off-Road Package with twin-tube Rancho® shocks and skid plates if your routes include rutted approaches, gravel lots, or unimproved access roads. The SLE is the right fit when you want a noticeable tech leap and smarter trailering tools without stepping away from the practical value of a hard-charging HD.
SLT
SLT is where elevated comfort meets advanced control. It adds a 10-way power driver and front outboard passenger heated seats with lumbar, plus a heated steering wheel to help keep you comfortable on long stints. The ProGrade® Trailering System with the In-Vehicle Trailering App simplifies hitching, diagnostics, and trailer profiles, giving you a clear command center for frequent towing tasks. Outside, 18-inch machined aluminum wheels with dark gray metallic accents showcase a more premium stance. You can also opt for ventilated front bucket seats with perforated leather appointments and add the available MultiPro™ Tailgate and MultiPro Tailgate Audio System by Kicker® to extend the truck’s versatility at the bed. At Alpine Buick GMC South, we see SLT hit the sweet spot for owners who want confident hauling, an upscale cabin, and trailering tech that streamlines busy schedules.

AT4
AT4 upgrades the SLT formula with off-road readiness and signature style. The exclusive Jet Black interior with Kalahari accents, along with heated and ventilated perforated front leather seating surfaces, delivers premium comfort in a purposeful cabin. Exclusive 20-inch gloss-black aluminum wheels set the tone, and available BFGoodrich® off-road tires boost grip when terrain gets unpredictable. An Off-Road Suspension Package with twin-tube Rancho® shocks and skid plates helps protect key components and maintain composure off pavement. When towing, up to 14 available camera views with HD Surround Vision give you extra perspective around the truck and trailer, and Adaptive Cruise Control with trailering is available for relaxed highway stretches with a load in tow. Consider the available 15-inch diagonal Head-Up Display with off-road inclinometer to keep critical data within your sightline when you’re navigating uneven surfaces. AT4 is the confident pick for buyers who want a highly capable heavy-duty truck that looks the part and backs it up with thoughtful tech, premium materials, and legitimate off-road hardware.
AT4X
AT4X is engineered for those who expect factory-built, go-anywhere hardware without sacrificing comfort. A 1.5-inch factory-installed suspension lift, Multimatic® DSSV dampers, a rear electronic-locking differential, a larger steel transfer case skid plate, and a front aluminum skid plate form a formidable foundation. Massive 35-inch Goodyear® Territory MT tires provide tenacious traction, while 16-way heated and ventilated power front seats with a massage feature support you through demanding outings. The Obsidian Rush interior brings full-grain leather seating with technical-grain leather accents and authentic Vanta ash wood, underscoring that this capability comes with genuine refinement. The AT4X AEV Edition is available with stamped steel bumpers, steering gear, and transfer case skid plates, and 18-inch Salta gloss-black wheels for even more rugged protection. Add the available Duramax® 6.6L Turbo-Diesel V8 for high-torque confidence across grades and altitude. If you need an HD truck that feels composed on the trail and unflappable under load, the 2026 GMC Sierra 2500 HD in Colorado Springs makes AT4X a standout choice.

Inside, Denali-exclusive authentic wood and patterned aluminum trim pair with Forge perforated leather seating surfaces for a refined, comfortable cabin. You’ll get 12-way heated and ventilated power front seats to support long workdays or extended trips, and you can add the available Duramax® 6.6L Turbo-Diesel V8 for maximum torque and confident grade control. An available power sunroof and an available Rear Camera Mirror further elevate the driving experience, adding light, space, and expanded rearward visibility.
