If off-roading is your goal, you have two impressive options to choose from in the GMC Sierra lineup — AT4 and AT4X. Here is a closer look at these enviable off-road ready trims, available now at Don Larson Chevrolet Buick GMC in Baraboo, Wisconsin.
GMC Sierra AT4
The AT4 is equipped with an automatic locking rear differential and a cabin outfitted in Jet Black. Perforated leather upholstery and Kalahari accents help complete the look. The AT4 engine offers a choice between two engines, a diesel and V8.
GMC Sierra AT4X
Giving you a smoother and more capable ride are Multimatic® DSSV spool-valve dampers. You also earn a Terrain driving mode for expert performance for rock crawling and more control with electronically-lockable, driver-selectable front and rear differentials.
Inside, the AT4X makes a bold statement with leather upholstery, accents in Vanta ash, massaging seat function, and Obsidian Rush color.
Since both models are designed to go where the road ends, each trim features specialized equipment including four-wheel drive, Hill Descent Control, and 2-inch factory lift with its off-road suspension design. Skid plates, DuraTrac® Mud-Terrain tires, and recovery hooks add to the off-road capability. A two-speed Autotrac® Transfer case features different modes for a customized driving performance. Both models also offer advanced driver assist tech.
