Dealer Description

The 2021 GMC Sierra 1500 SLT delivers a perfect combination of power, precision, and premium comfort in a full-size pickup designed to meet the demands of both work and everyday life. Finished in Summit White, this Sierra 1500 SLT projects professional-grade strength with its bold chrome-accented grille, signature C-shaped LED headlamps, and sculpted hood that convey confidence and capability. Chrome mirror caps, door handles, and bumpers enhance its refined look, while 18-inch bright machined aluminum wheels and LED cargo bed lighting add both style and functionality. The GMC MultiPro Tailgate with six unique functions ensures unmatched versatility, making it easy to load, haul, and work efficiently. Under the hood, the 2021 Sierra SLT is powered by a 5.3-liter EcoTec3 V8 engine paired with a 10-speed automatic transmission, delivering 355 horsepower and 383 lb-ft of torque. This powertrain provides impressive towing capability and smooth, controlled performance whether hauling heavy loads or cruising the highway. Equipped with a fully boxed high-strength steel frame and available four-wheel drive, the Sierra handles tough terrain with ease. The Adaptive Ride Control suspension and electric power steering system deliver a composed, confident ride, while features like Trailer Sway Control and Hitch Guidance with Hitch View make towing simple and secure. Inside, the Sierra SLT surrounds you with luxury and craftsmanship, combining comfort with functionality. The spacious Crew Cab features Jet Black leather-appointed seating with perforated inserts, complemented by real aluminum trim and soft-touch materials throughout. Both front seats are heated and ventilated, with 10-way power adjustments and driver memory settings for personalized comfort. The heated, leather-wrapped steering wheel and dual-zone automatic climate control create a refined driving environment, while the rear seats fold up easily to reveal additional interior storage. From its premium finishes to its thoughtful ergonomics, the SLT's cabin exemplifies GMC's attention to detail. Technology in the 2021 Sierra SLT is intuitive and advanced. At its core is the GMC Premium Infotainment System with an 8-inch color touchscreen featuring Apple CarPlay, Android Auto, Bluetooth streaming, and navigation. The available Bose premium sound system provides crisp, immersive audio, while the 4.2-inch color Driver Information Center keeps key vehicle data within easy view. Additional conveniences include wireless phone charging, multiple USB-C ports, remote start, and keyless open and start. Wi-Fi hotspot capability keeps you connected wherever you go, and the multi-camera trailering system enhances safety and control when towing. Safety is a cornerstone of the Sierra SLT's design, featuring a suite of advanced technologies for added confidence. Every eligible pre-owned vehicle at Walt Massey dealerships includes a complimentary 3-month/3,000-mile powertrain warranty through Owner Services, Inc. This coverage safeguards essential components such as the engine, transmission, and drive axle, while also including towing assistance and rental reimbursement for unexpected breakdowns. The 2021 GMC Sierra 1500 SLT embodies the perfect balance of strength, luxury, and intelligence-crafted for drivers who expect professional-grade performance and premium comfort in a truck that works as hard as they do.
