Dealer Description

PAVEMENT IS OVERRATED...Sierra AT4 includes a 2 inch factory-installed suspension lift for elevated ground clearance to help overcome rough terrain. Explore the unbeaten path with the available 6.2L gas V8 with 10-speed automatic transmission. The Traction Select System allows you to choose Off-Road mode for optimum transmission, throttle and StabiliTrak performance on unpaved surfaces. To help provide more traction in snow, mud, ice, sand or gravel, 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. Inside AT4, you will find an athletic, purposeful interior designed for your active lifestyle. It features unique darkened trim and decor, perforated front leather seating surfaces in Jet Black with Kalahari accents and smart storage compartments. In addition, the available multicolor 15 inch diagonal Head-Up Display projects key information onto the windshield to help you keep your eyes on the road. Information includes an Off-Road Inclinometer that shows the fore-and-aft tilt, front tire angle and left-and-right tilt. The Driver Alert Package picks up adaptive cruise control, front pedestrian braking, forward collision alert, lane keep assist, automatic emergency braking and a safety alert seat. Always looking for better ways to get things done. That is the pro way. It is what drove GMC engineers to create Sierra. With its strong, elevated stance, revolutionary capabilities, innovative technologies and remarkable power, Sierra leads in the best possible way by example.
