The 4WD system, combined with off-road suspension and an auto-locking rear differential, ensures capable performance when the pavement ends.
Inside, luxury meets functionality. Premium leather seating with heating and ventilation technology keeps you comfortable mile after mile. The heated steering wheel responds to cold climates, while the wireless charging pad and extensive USB connectivity keep your devices powered throughout your day. Entertainment flows seamlessly through the Bose sound system with SiriusXM capability, while Apple CarPlay and Android Auto put your digital life at your fingertips.
Technology enhances both safety and convenience throughout the cab. The power sunroof floods the interior with natural light, while the 15-inch head-up display keeps critical information in your line of sight. The rear camera mirror, bed view camera, and surround vision system eliminate blind spots and build confidence during tight maneuvers. Forward collision alert, automatic emergency braking, lane departure warning, and rear cross traffic braking work together to support your awareness on the road.
Practicality defines the Sierra 1500 AT4. The spray-on bedliner protects your cargo area, while the power sliding rear window with defogger improves ventilation and bed access. All-weather floor liners safeguard the interior, and the integrated trailer brake controller with in-vehicle trailering system app makes towing straightforward and secure.
This 2026 Sierra 1500 AT4 represents genuine truck craftsmanship—a vehicle that refuses to compromise between capability and refinement. With 11,716 miles, it's been lightly used and thoroughly maintained, ready for years of dependable service. We invite you to experience this outstanding truck firsthand and discover why it stands apart in its class.
