2026 GMC Sierra 2500HD AT4

This lifted 2026 GMC Sierra 2500HD AT4 Crew Cab 4x4 has the power, stance, and color combination to stop people in their tracks. The all-new Coastal Dune exterior is fully color-matched and paired with gloss black AT4 accents, an aggressive front end, and red recovery hooks. Inside, the Jet Black leather with Kalahari accents gives the cabin the sharp, high-end look expected from an AT4. The professionally installed 5-inch Zone Offroad lift kit with Fox Adventure Series shocks gives this heavy-duty GMC the perfect height and aggressive stance. Brand-new gloss black 20-inch Hostile Titan wheels and brand-new 37x12.50R20LT Toyo Open Country tires complete the build. This setup looks right from every angle and gives the truck a tough lifted appearance without taking away from the clean factory styling. Power comes from the proven 6.6-liter Duramax turbo-diesel V8 paired with the smooth Allison 10-speed automatic transmission. An automatic locking rear differential, two-speed AutoTrac transfer case, Traction Select System with Off-Road and Tow/Haul modes, skid plates, heavy-duty air cleaner, digital variable steering assist, and 220-amp alternator make this Sierra ready for work and weekend adventures. It is also equipped with the factory trailering package, integrated trailer brake controller, in-vehicle trailering app, and StabiliTrak with trailer sway control and hill start assist.
