New 2026 GMC Sierra 2500HD

The 2026 GMC Sierra 2500HD AT4X Crew Cab 4WD in Sterling Metallic brings serious off-road engineering to a premium heavy-duty pickup. Its 6.6L Duramax turbo-diesel, Multimatic DSSV dampers, electronic locking rear differential, and 35-inch mud-terrain tires are built for demanding terrain. This particular truck adds a tri-fold hard tonneau cover, gooseneck/fifth-wheel preparation, and rear under-seat storage. Inside, the Obsidian Rush cabin, power sunroof, and 15-inch head-up display make the journey as rewarding as the destination.
