This 2024 GMC Sierra 2500HD AT4X in Thunderstorm Gray looks like it was forged inside an actual storm cloud—bold, aggressive, and ready to dominate absolutely everything in its path. With only 15,924 miles and a clean, no-accident history, this AT4X is barely broken in and already flexing one of the most intimidating stances in the HD world. The Thunderstorm Gray finish paired with the Obsidian Rush leather interior gives it a premium-meets-pure-attitude vibe that fits the AT4X name perfectly.

Under the hood, the Sierra 2500HD AT4X delivers serious heavyweight capability, built for drivers who want luxury and ruggedness in equal measure. Built on GMC’s off-road-focused platform, this truck brings enhanced suspension tuning, off-road hardware, and the kind of ground clearance that says, “Go ahead—try me.” Whether you’re towing, hauling, or pointing the nose toward a trail most people wouldn’t dare attempt, the AT4X stands ready. The Preferred Equipment Group 4SG ensures you get all the advanced features, tech upgrades, and high-end touches that make this truck feel as premium as it is capable.

Inside, the Obsidian Rush leather interior is a masterpiece—bold red accents, premium stitching, and AT4X-exclusive touches that turn the cabin into a high-end command center. Heated and ventilated seats, advanced infotainment, premium audio, and intuitive controls make this truck feel just as good on long highway drives as it does crawling over uneven terrain. It’s upscale, rugged, and unmistakably GMC Denali-level luxury wrapped in an off-road package.
