What Does AT4 Mean in the GMC World?
GMC’s AT4 badge stands for All-Terrain 4WD—a suite of upgrades designed for off-road exploration and rugged utility. From the compact Terrain to the heavy-duty Sierra HD, AT4 trims offer specialized suspension, underbody protection, and enhanced 4×4 capability. In Texas, where dirt trails and backroads are part of everyday life, AT4 makes perfect sense.
Sierra 1500 AT4: A Texas-Sized Off-Road Pickup
The 2025 Sierra 1500 AT4 features a 2-inch factory lift, off-road-tuned Rancho shocks, and skid plates to tackle the Texas backcountry. The available 6.2L V8 gives it serious muscle, while the AT4-exclusive grille, red tow hooks, and all-terrain tires add trail-ready style. Perfect for exploring leases or hitting the trails after work.
Sierra HD AT4: Big Truck, Bigger Trails
Need more power? The Sierra 2500 and 3500 HD AT4 models take off-roading to a heavy-duty level. With an available Duramax® diesel engine, advanced traction systems, and serious ground clearance, these trucks are built for ranches, remote job sites, and recreational off-roading in rugged Texas terrain.
Canyon AT4 and AT4X: Mid-Size Agility with Hardcore Features
The Canyon AT4 is nimble, durable, and ideal for trails where full-size trucks struggle. It includes hill descent control, a standard lift, and a durable underbody skid plate. For extreme off-roaders, the AT4X adds Multimatic DSSV dampers, front/rear e-lockers, and AEV steel bumpers—turning the Canyon into a true trail beast.
Yukon AT4: Adventure SUV with Luxury Features
Want SUV comfort with off-road chops? The Yukon AT4 blends the two seamlessly. You get four-corner air suspension, underbody protection, all-terrain tires, and a confident 4WD system—plus leather-appointed seats, a panoramic sunroof, and Bose® audio. Ideal for Texas families who head to the lake or ranch on weekends.
Terrain AT4: Compact and Capable
Even the smaller Terrain has an AT4 variant. While it’s not built for rock crawling, it does include hill descent control, a front skid plate, and advanced AWD. It’s great for light trails, muddy roads, and those who want off-road capability in a manageable package—perfect for Graham commuters who love weekend getaways.
