GMC offers two excellent off-road options: the **AT4** and the **AT4X**.

The **AT4** is designed for adventurous drivers who tackle trails and job sites alike. It features a factory lift, Rancho shocks, all-terrain tires, skid plates, and a robust 4WD system. Inside, you get durable yet refined materials for all-day comfort-aggressive styling meets rock-solid resilience.

The **AT4X** takes off-road performance to the extreme with Multimatic DSSV dampers, locking differentials, and 35-inch terrain tires. The optional AEV Edition adds rugged, off-road-specific enhancements like stamped-steel bumpers, skid plates, and special badging-built for serious enthusiasts demanding maximum durability.

Both are factory-engineered for real adventure. Contact Markquart Motors at (715) 833-0444 to discuss which off-road capability matches your terrain and driving style.
