The GMC Sierra HD AT4 is built for drivers who tackle trails and job sites with equal confidence. It comes standard with a factory suspension lift, Rancho shocks, all-terrain tires, skid plates, and a robust 4WD system. The interior balances durable yet refined materials for long-day comfort. For extreme off-road seekers, the AT4X steps up further with Multimatic DSSV dampers, locking differentials, and 35-inch terrain tires. The optional AEV Edition adds stamped-steel bumpers and additional skid plates for unmatched durability.
