Description
THIS… is a 2021 GMC Sierra 1500 AT4 Crew Cab 4×4 Black Widow Edition finished in silver over a black leather interior, showing 35,700 miles. Combining GMC’s off-road-focused AT4 trim with Black Widow custom upgrades, this truck delivers diesel efficiency, lifted stance, and premium technology in a distinctive package.
Power comes from the 3.0-liter turbocharged Duramax diesel engine paired with a 10-speed automatic transmission and four-wheel drive. Known for strong torque and everyday drivability, this powertrain balances efficiency with towing capability.
This two-owner example features the AT4 Premium Package along with GMC’s Technology and Driver Alert packages, adding advanced safety systems, surround-view cameras, adaptive cruise control, and a head-up display. Black Widow upgrades include a 6-inch suspension lift, aggressive styling accents, fender flares, tinted glass, and oversized wheels wrapped in new Toyo mud-terrain tires.
Interior highlights include heated and ventilated leather seating, dual-zone climate control, premium infotainment, and an upgraded audio setup featuring a Kicker subwoofer. The result is a well-equipped diesel pickup that blends off-road presence with modern comfort.
