Overview
The GMC Sierra 1500 is a spacious and capable pickup. It is offered in a number of trims providing a wide array of creature comforts. While GMC might be more sooner associated with the chrome-clad Denali variants, the Sierra is also available in more outdoorsy trims, such as the AT4. Designed as a sort of the anti-Denali, the AT4 is designed to get muddy. It features a 2-inch lift, Rancho shocks, upgraded underbody skid plates, an Auto-Trap two-speed transfer case, and a locking rear differential. The AT4 is not without niceties, as it receives a unique black interior with Kalahari accents and a host of creature comforts. The AT4 trim was introduced with the redesigned Sierra 1500 in 2019 and has continued through the 1500’s 2022 model year update.
Key Features
