Off-road capability meets heavy-duty muscle in this 2026 GMC Sierra 2500HD AT4 Crew Cab 4WD. The 6.6L V8 gas engine pairs with the Allison 10-speed automatic to deliver stout torque and lower up-front cost than diesel, while the AT4 package adds skid plates, all-terrain hardware, and a Traction Select system for real trail ability. Finished in Coastal Dune with a Jet Black and Kalahari interior, this three-quarter-ton is built for South Dakota and North Dakota work and adventure alike.
This AT4 comes ready to tow and wander, with a gooseneck/fifth-wheel package, GMC MultiPro tailgate, spray-on bedliner, and animated LED projector headlamps rounding out a genuinely job-site-ready package.
According to Kelley Blue Book and Edmunds, the GMC Sierra 2500HD is praised for its strong towing, durable powertrains, and comfortable cabin. The AT4 trim adds genuine off-road hardware and rugged styling, and the 6.6L gas V8 is a favorite for buyers who want big-block torque without the diesel premium.
