Dealer Description

The 2021 GMC Sierra 1500 SLT Crew Cab delivers a perfect combination of rugged capability, refined comfort, and advanced technology in a full-size pickup built for both work and everyday driving. Finished in Summit White, this Sierra SLT makes a commanding statement with its bold chrome-accented grille, signature C-shaped LED headlamps, and sculpted hood. Chrome mirror caps, body-colored door handles, and 20-inch bright machined aluminum wheels enhance the exterior's premium look, while the GMC MultiPro Tailgate and bed lighting provide functional versatility for hauling and loading tasks. Under the hood, the 2021 Sierra SLT is powered by a 5.3-liter EcoTec3 V8 engine paired with a smooth 10-speed automatic transmission, producing 355 horsepower and 383 lb-ft of torque. This strong and reliable powertrain offers excellent towing capability-up to 8,200 pounds when properly equipped-and responsive performance both on the highway and off the beaten path. Available four-wheel drive, along with selectable drive modes, enhances traction and handling in diverse conditions, while the Sierra's fully boxed frame and independent front suspension deliver a smooth, composed ride under heavy loads. Inside, the Sierra SLT combines premium comfort with thoughtful functionality. The Jet Black leather-appointed seating with perforated inserts and heated front seats provides an upscale environment, while the 10-way power-adjustable driver seat with memory and 4-way power front passenger seat offer personalized comfort. The rear bench provides ample space for passengers, and foldable rear seats expand interior storage for additional versatility. Dual-zone automatic climate control, a leather-wrapped steering wheel, and soft-touch materials create a refined and comfortable cabin experience. Technology in the 2021 Sierra SLT is advanced and easy to use. The 8-inch GMC Infotainment system includes Apple CarPlay, Android Auto, Bluetooth, and navigation. A premium Bose 8-speaker audio system delivers immersive sound, while USB ports, wireless charging, and a digital Driver Information Center provide convenience and connectivity. Additional features such as remote start, keyless open and start, and a multi-camera trailering system enhance functionality and safety for towing and maneuvering. Safety is a priority in the Sierra SLT, featuring standard and available technologies such as Forward Collision Alert, Automatic Emergency Braking, Lane Keep Assist with Lane Departure Warning, Front and Rear Park Assist, Rear Cross Traffic Alert, and Side Blind Zone Alert. The reinforced high-strength steel frame and advanced airbag system provide exceptional protection for all occupants, while trailer sway control and integrated braking systems offer confidence when towing heavy loads.
