GMC Sierra AT4 Jumps in the Mud

The 2019 GMC Sierra is the first of the AT4 model series to roll off the production line and is proof positive that GMC is going after the off-road market. Surprising considering GMC’s past focus on luxury and fancy touches, but this truck has none of that (well, it still a handsome and comfortable looking truck with all the amenities you might want, but it’s not a town car either). The AT4 comes with a factory install lift kit that raises the truck two inches. Rancho monotube shocks, a locking rear differential, a two-speed transfer case, and standard all-wheel drive accompany that two inch raise, making the off-road possibilities more of a reality. But what about power? Does a 5.3 liter V8 attached to an eight-speed automatic transmission sound good enough? The AT4 is capable of at least 355 horsepower. If that’s not enough engine, then you could also choose from the 3.0 liter inline six, or a 6.2 liter V8, both with a 10-speed automatic transmission.

The bed is a carbon-fiber cargo bed, which cuts off 62 pounds of weight compared to the traditional all-steel bed. The end of the bed is topped off with a MultiPro tailgate that folds into six configurations to better secure cargo. It also serves as a step into the truck bend and can even lip down partially to become an onsite work desk. The GMC Sierra AT4 has plenty to offer—either off road or as a commuter.
