This 2021 GMC Sierra 1500 AT4 isn’t just a truck—it’s a bold, blacked-out force of nature with luxury built right into its DNA. Finished in commanding Onyx Black with a premium black leather interior, this AT4 is equally at home on rugged trails and upscale streets. With 91,325 miles under its belt, it’s already proven its toughness—and it's ready for plenty more.

Built to stand apart, the AT4 trim brings a factory lift, off-road suspension, skid plates, and an aggressive stance that doesn’t just suggest capability—it demands attention. Whether you’re towing, hauling, or heading up into the mountains for a weekend escape, this Sierra delivers serious performance without breaking a sweat.

Inside, the cabin is all about comfort, control, and confidence. Dual-zone climate control keeps everyone happy, while Apple CarPlay seamlessly integrates your favorite apps and entertainment. Heated and ventilated seats, plus a heated steering wheel, make this truck a year-round champion—cozy in winter, cool in summer, and always ready to work or play.
