The AT4 trim adds off-road confidence while still delivering a smooth and controlled ride on the highway. Its a truck built for drivers who need real strength and aren't afraid to use it. Inside, the Sierra 3500HD AT4 offers a refined cabin with premium leather seating that balances durability with comfort.
