Dealer Description

This red 2021 GMC Sierra 1500 Crew Cab AT4 with a 147" wheelbase is a high performance pickup designed for those who split their time between the highway and the trail. With 57,170 miles, this truck features the AT4's signature factory 2 inch suspension lift and rugged off road tuning, offering a more commanding view of the road and increased ground clearance. The 147" wheelbase signifies the popular Short Box configuration, which balances exceptional interior passenger space with a maneuverable footprint that is easier to park and navigate through tight spots than its long bed counterparts. Performance is driven by a standard 5.3L EcoTec3 V8 engine producing 355 horsepower, though it was also available with the massive 6.2L V8 or the efficient 3.0L Duramax Diesel. Every AT4 comes standard with a 2 speed Autotrac transfer case, skid plates, and off road tuned Rancho monotube shock absorbers to handle unpredictable terrain. The exterior is highlighted by the world's first six function MultiPro Tailgate, which provides unmatched versatility for loading cargo, acting as a bed extender, or even transforming into a full width step for easy access to the bed. Inside, the Crew Cab offers a premium environment with Jet Black leather seating surfaces featuring unique Kalahari accents. The cabin is loaded with convenient technology, including a high resolution infotainment system with smartphone integration and the ProGrade Trailering System to simplify hauling tasks. Safety is a major focus, with standard features like a Rear Vision Camera and a suite of available driver assistance technologies. This red 2021 Sierra AT4 is a bold, capable, and well maintained truck that is ready for any challenge.
