Used 2021 Gmc Sierra 1500 AT4

This 2021 GMC Sierra 1500 AT4 4x4 is a rugged yet refined pickup with only 59,000 miles, finished in Onyx Black with a premium Jet Black interior accented by Kalahari details. Powering this truck is the impressive 3.0L Duramax Turbo-Diesel inline-6 paired with a 10-speed automatic transmission, delivering excellent torque, efficiency, and towing confidence. The AT4 trim is purpose-built for off-road performance, equipped with the X31 Off-Road Suspension featuring a factory 2-inch lift, monotube shocks, skid plates, and hill descent control. The Autotrac 2-speed transfer case and automatic locking rear differential enhance traction in challenging conditions, while the integrated trailer brake controller and ProGrade Trailering System simplify towing. A spray-in bedliner with AT4 logo, hard folding tonneau cover, and multipro tailgate ensure the bed is as functional as it is durable. Inside, the cabin balances ruggedness with premium comfort. Heated and ventilated 10-way power front seats, heated rear seats, dual-zone climate control, and a heated leather-wrapped steering wheel elevate the driving experience. The AT4 Value Package adds a Bose premium sound system, navigation, wireless Apple CarPlay/Android Auto, wireless charging, memory settings, and a power sliding rear window for added convenience.
