Dealer Comments

This Red 2021 GMC Sierra 1500 AT4 4WD Crew Cab is a high performance off road pickup that combines aggressive capability with premium interior refinement. With 37,856 miles, this truck is barely broken in and ready for both demanding work and weekend adventures. The AT4 trim is purpose built for the trail, featuring a 2 inch factory installed suspension lift, Rancho monotube shocks, and a two speed AutoTrac transfer case with an automatic locking rear differential to handle the toughest terrain. Under the hood, this Sierra is powered by a potent V8 engine (available in 5.3L or 6.2L configurations) paired with a smooth shifting 10 speed automatic transmission, providing plenty of low end torque for towing up to 9,200 lbs. The exterior is finished in a striking Red with black chrome accents and features the innovative GMC Multi Pro Tailgate, which offers six unique functions to improve loading and cargo access. Inside the spacious Crew Cab, you will find an exclusive Jet Black interior with Kalahari accents, featuring heated and ventilated leather front bucket seats and a heated steering wheel for maximum comfort. Technology and safety are front and center in this 2021 model, which includes the GMC Infotainment System with an 8 inch touchscreen, Apple CarPlay, and Android Auto. This AT4 also comes equipped with advanced driver assistance features such as Front and Rear Park Assist, Lane Change Alert with Side Blind Zone Alert, and a high definition Rear Vision Camera. With its combination of rugged off road hardware and a luxury grade cabin, this GMC Sierra AT4 stands out as one of the most capable and stylish trucks in its class.
