GMC introduces the new off-road focused AT4X trim for the 2023 Sierra 1500 pickup.

The AT4X comes with a factory 2-inch suspension lift and 33-inch all-terrain tires for increased ground clearance.

Both front and rear electronic locking differentials improve traction over rugged terrain.

Skid plates and rocker panel protectors shield vital components from off-road damage.

An optional AEV performance package adds front/rear bumpers, wheels, underbody cameras, and more custom parts.

A standard 6.2-liter V8 makes 420 horsepower and 460 lb-ft of torque, providing strong acceleration.

The AT4X retains a max tow rating of 9,900 lbs for hauling boats, ATVs, and camping trailers.
