The AT4 and AT4X trims add a factory-installed 2-inch suspension lift, Rancho monotube shocks or Multimatic DSSV dampers, underbody skid plates, and available front and rear electronic locking differentials a combination not offered on any competitor in its class.

Step inside the 2026 Sierra 1500 and you'll find a cabin designed around both comfort and function. The Sierra 1500 offers best-in-class standard Crew Cab front head- and legroom, giving every passenger plenty of space to settle in. Available seating options range from a standard 40/20/40 bench seat to available leather-appointed front seating surfaces with heating, ventilation, and power adjustability.
