2024 GMC Sierra 2500HD AT4

OWN THE KIND OF TRUCK THAT MAKES EVERY JOB, EVERY WEEKEND, AND EVERY ARRIVAL FEEL BIGGER The 2024 GMC Sierra 2500HD AT4 Crew Cab in Volcanic Red Tintcoat is not built for half-measures.

This Certified heavy-duty truck shows up with the kind of presence that turns a worksite, a driveway, or a trailhead into its own statement before the engine even settles.

The deep Volcanic Red Tintcoat finish, the commanding stance of 4WD, the bold utility of the AT4 high-clearance step, the rugged confidence of the GMC MultiPro tailgate, the ready-for-anything look of the spray-on bedliner with AT4 logo, the open-air lift of the power sunroof, and the unapologetic strength of the front recovery hooks all come together to make this Sierra feel like more than a truck.

It feels like a declaration.

Under the hood, the 6.6L V8 gasoline engine paired with the Allison 10-speed automatic transmission delivers the kind of strength that feels effortless when the load gets serious.

The added authority of the automatic locking rear differential and 2-speed transfer case gives this AT4 the kind of confidence that matters when pavement disappears, when weather turns ugly, or when the road ahead starts asking harder questions.

This is where the truck earns its name, not in theory, but in the way it feels pulling through Blissfield, Marshall, and Southgate across Ingham County, St.

Joseph County, and Wayne County, then driving hard and steady along I-75, M-99, and M-106 with the kind of muscle that makes the whole day feel under control.

Inside, the cabin brings serious comfort to serious capability.

The Jet Black interior with Kalahari accents, 10-way power front bucket seats, heated front seats, heated rear outboard seats, driver memory settings, heated steering wheel, and dual-zone climate control give this Sierra the kind of interior that makes long hauls, early starts, and cold mornings feel easier to carry.

It is the kind of truck that lets you work hard without feeling punished by the miles, a truck that still feels refined at the end of a long day and ready to do it again tomorrow without complaint.

Technology sharpens that confidence even further.

The Trailer Brake Controller, premium GMC infotainment system with 13.4-inch touchscreen and navigation, 12.3-inch driver information display, Bose premium 7-speaker audio system, adaptive cruise control, rear camera mirror, and multi-color head-up display make this Sierra feel smart, aware, and fully ready for the demands of modern towing, highway travel, and daily life.
