When it comes to trucks, it seems as though everyone wants the lifted off-road look. That’s why the 2021 GMC Sierra AT4 exists. In addition to a custom appearance with body-color bumpers, grille, and trim, the Sierra AT4 adds a 2-inch suspension lift for extra ground clearance, off-road shocks, skid plates, mud-terrain tires, and purposeful red front recovery hooks. Equipped with a two-speed Autotrac transfer case and a locking rear differential, it’s ready for rugged terrain right off of the assembly line.
The AT4 is just one of five different Sierra models you can buy. The truck also comes in SLE, Elevation, SLT, and luxurious Denali trims. Depending on which one you choose, you can get a regular cab with a long bed, an extended cab with a standard bed, or a crew cab with a standard or short bed. Our AT4 test truck was loaded with extras, including Premium, Technology, and Preferred option packages; a 3.0-liter turbodiesel six-cylinder engine; a CarbonPro carbon fiber composite cargo bed; and more. The price came to $66,595, including a $1,695 destination charge.
