What makes a 2024 Sierra 2500 HD even better? Adding the new AT4X off-road package with some AEV goodies added on. Plus the 6.6 Duramax diesel and Alison transmission. About as awesome as it gets.

2023 GMC Sierra 1500 AT4 is an All-Around Off-Roader
With several dash-worthy adjectives supporting it, the 2023 Sierra in its AT4X package is a good regular-use off-road machine. The package adds a little lift, better off-pavement tires, tow hooks, and a few other things to improve the four-by-four nature of the truck. Aaron gives the skinny.
