SLE
13.4-inch center touchscreen · 12.3-inch Driver Information Center · Traction Select System · 17-inch machined aluminum wheels
The SLE moves the Sierra 2500 HD into a more technology-rich space while preserving the practical attitude that heavy-duty truck shoppers value. Its 13.4-inch diagonal center touchscreen and 12.3-inch diagonal digital Driver Information Center bring key information into clearer view, which is especially helpful when switching between towing, commuting, and worksite tasks. The Traction Select System with Tow/Haul mode helps the truck adapt to different driving demands, whether the day involves a loaded trailer, a supply run, or a stretch of highway. The SLE also introduces 17-inch machined aluminum wheels, adding a polished look without losing its functional edge. Available up to 13 camera views, including transparent trailer view, can make low-speed maneuvering and trailer alignment feel more manageable. Shoppers can also add the MultiPro™ Tailgate, MultiPro Tailgate Audio System by Kicker®, and the X31 off-road package with twin-tube Rancho® shocks and skid plates. The SLE is a smart step up for drivers who want modern displays, useful trailering visibility, and available off-road equipment in one balanced package.

SLT
10-way power heated front seats · Heated steering wheel · ProGrade® Trailering System · 18-inch aluminum wheels
The SLT is where the Sierra 2500 HD begins to feel especially well suited for drivers who spend serious time behind the wheel. It adds 10-way power driver and front outboard passenger heated seats with lumbar support, plus a heated steering wheel, giving the cabin a more accommodating feel for long hauls, early starts, and back-to-back errands. The ProGrade® Trailering System with In-Vehicle Trailering App is one of its most important upgrades because it helps organize trailering information in a more intuitive way. That kind of support can make a real difference for owners who regularly tow utility trailers, enclosed cargo trailers, livestock trailers, or boats. The SLT also includes 18-inch machined aluminum wheels with dark grey metallic accents, giving it a more upscale appearance than the lower trims. Available heated and ventilated bucket seats with perforated leather appointments further enhance comfort, while the available MultiPro Tailgate and MultiPro Tailgate Audio System by Kicker add versatility at the rear of the truck. For many shoppers, SLT is the practical premium choice.

AT4
Jet Black interior with Kalahari accents · 20-inch gloss-black aluminum wheels · Off-Road Suspension Package · HD Surround Vision
The AT4 is the Sierra 2500 HD trim for drivers who want heavy-duty strength with factory-backed off-road character. It builds from the SLT foundation and adds an exclusive Jet Black interior with Kalahari accents, heated and ventilated perforated front leather seating surfaces, and exclusive 20-inch gloss-black aluminum wheels with available BFGoodrich® off-road tires. Its Off-Road Suspension Package includes twin-tube Rancho shocks and skid plates, helping the truck feel more prepared for unpaved roads, rural properties, jobsite entrances, hunting land, and boat ramps. Up to 14 available camera views with HD Surround Vision help improve awareness around the truck and trailer, while Adaptive Cruise Control with trailering adds confidence during longer towing routes. An available 15-inch diagonal Head-Up Display with off-road inclinometer gives the AT4 an extra layer of information for drivers who like to keep key details in sight. Near Manning, SC, where paved highways can quickly give way to farm lanes, timber roads, and lake access routes, the AT4 offers a compelling mix of capability, technology, and rugged style.
AT4X
1.5-inch suspension lift · Multimatic® DSSV dampers · Rear electronic-locking differential · 35-inch Goodyear® Territory MT tires
The AT4X takes the off-road theme further with specialized hardware and a more premium cabin. Its factory-installed 1.5-inch suspension lift, Multimatic® DSSV dampers, rear electronic-locking differential, larger steel transfer case skid plate, and front aluminum skid plate give it a more serious trail-ready configuration than the AT4. The 35-inch Goodyear® Territory MT tires add traction-focused capability and a bolder stance, while the available AT4X AEV Edition goes even further with stamped steel bumpers, steering gear and transfer case skid plates, and 18-inch Salta gloss-black wheels. Inside, the AT4X is far from stripped down. It includes 16-way heated and ventilated power front seats with massage feature, plus an Obsidian Rush interior with full-grain leather seating, technical-grain leather accents, and authentic Vanta ash wood. That combination gives the AT4X a distinct identity: tough enough for challenging terrain, yet refined enough to make daily use feel special. It is ideal for drivers who want a heavy-duty truck that can tow, travel, explore, and still feel upscale on every mile.
Denali
20-inch Ultra-Bright machined aluminum wheels · Authentic wood trim · Forge perforated leather · 12-way power front seats
The Denali trim brings a different kind of confidence to the 2026 Sierra 2500 HD. Rather than emphasizing trail hardware, it focuses on premium materials, a commanding appearance, and an elevated ownership experience. Denali-exclusive authentic wood, patterned aluminum trim, and Forge perforated leather seating surfaces create a cabin that feels polished without losing the truck’s purposeful nature. The 12-way heated and ventilated power front seats support comfort for long drives, business use, and frequent towing days. Outside, 20-inch Ultra-Bright machined aluminum wheels with bright chrome inserts help give the truck a distinctive Denali presence. Available features such as the Duramax® 6.6L Turbo-Diesel V8 engine, power sunroof, and Rear Camera Mirror allow shoppers to tailor the truck for more capability and convenience. Denali is especially appealing for owners who want one truck to handle professional responsibilities, personal travel, and weekend towing without feeling like a compromise.

Denali Ultimate
Duramax® 6.6L Turbo-Diesel V8 · Vader Chrome grille · Alpine Umber interior · 12-Speaker Bose Premium Series
