Check the price in your area:

Building upon the AT4, the AT4X is a strong combination of luxury and superlative off-roading, with all of the AT4's off-road gear and more, in addition to most of the Denali trims' luxuries. The brawnier 6.2-liter V8 is standard, and it has Multimatic DSSV spool-valve dampers and special springs that further increase suspension travel relative to the AT4. Front and rear e-locking differentials and a larger steel transfer case shield are further additions. Inside, it’s suitably luxurious with heated, ventilated, and massaging front seats, a 12-speaker Bose sound system, a power sunroof, and a premium microsuede headliner. It even has a standard weatherproof Kicker audio system integrated into the MultiPro tailgate. This trim is also available in a hardcore off-road 2023 AEV Edition that adds an AEV steel rear bumper, five AEV skid plates, black AEV racing-inspired 18-inch Salta alloy wheels, off-road rocker-panel protectors, embroidered headrests, and exclusive AEV badging.
