New 2020 GMC
Sierra AT4 includes a 2" factory-installed suspension lift for elevated ground clearance to help overcome rough terrain. Explore the unbeaten path with the available 6.2L V8 or 3.0L Duramax Turbo Diesel engine with 10-speed transmission. The Traction Select System allows you to choose Off-Road mode for optimum transmission, throttle and StabiliTrak performance on unpaved surfaces. And the standard 2-speed AutoTrac transfer case with low-range 4WD gearing helps handle a variety of off-road conditions. Venturing downhill, Hill Descent Control uses antilock braking to help control descent on rugged terrain. And to help maneuver out of deep, loose terrain, AT4 includes an automatic locking rear differential. Further helping smooth out the rough spots are Rancho monotube shocks, while metal skid plates help protect the front underbody
Sierra SLE is all about doing things—and doing them well.
