Dealer Description

This Sterling Metallic 2021 GMC Sierra 1500 AT4 Crew Cab is a rugged yet refined off road specialist designed for those who demand both trail capability and premium comfort. With 73,877 miles, this truck is well seasoned for adventure and features the 147 inch wheelbase (Short Box configuration) that provides excellent maneuverability without sacrificing cab space. The AT4 trim is a standout in the Sierra lineup, coming standard with a 2 inch factory installed suspension lift, Rancho monotube shocks, and a two speed Autotrac transfer case, allowing it to tackle difficult terrain with ease. Its exterior is finished in the sleek Sterling Metallic paint, accented by the signature AT4 black chrome grille and functional red vertical recovery hooks. Inside, the cabin offers a sophisticated "blacked out" aesthetic with Jet Black leather seating featuring unique Kalahari orange accents. As a premium off road model, it comes equipped with heated and ventilated front bucket seats, a heated steering wheel, and dual zone automatic climate control to keep passengers comfortable in any environment. This 2021 model also benefits from advanced technology, including the MultiPro Tailgate with six unique functions and an 8 inch diagonal infotainment system that supports wireless Apple CarPlay and Android Auto. For towing and hauling, the truck includes the ProGrade Trailering System with an in vehicle trailering app, making it simple to hitch up a boat or camper and hit the road. Under the hood, you will typically find the potent 5.3L EcoTec3 V8 engine, delivering 355 horsepower and 383 lb ft of torque, paired with a smooth 10 speed automatic transmission. At nearly 74,000 miles, this Sierra 1500 has reached a point where regular maintenance is essential for continued performance; it is a good time to verify that the 4WD fluids have been serviced and the brake pads have been inspected. With its combination of a high clearance stance, heavy duty skid plates, and a refined interior, this Sterling AT4 is a versatile powerhouse that transitions perfectly from the job site to the trailhead.
