This new model, along with the AEV Extreme edition, promises to push the boundaries of off-road driving with a unique blend of performance, luxury, and technology.

Unmatched off-road performance

The 2024 Sierra Heavy Duty AT4X is designed for adventure seekers who demand a robust and high-performing truck. With an impressive towing capacity of 8,391 kg (18,500 lb) and a 38 mm (1.5 in) suspension lift system, this model offers superior off-road capability. Multimatic DSSV dampers provide exceptional suspension response, optimizing handling and comfort on uneven surfaces.

Coupled with 35-inch Goodyear Territory tires, these features ensure a smooth and stable ride, even on the most challenging trails.

The AT4X is not just about performance; it also includes practical enhancements for protection and comfort. The larger steel skid plate shields critical components from impacts and damage during off-road adventures. Inside, the model features an exclusive Obsidian Rush interior, with full-grain leather seats equipped with a massage function. These elements add a touch of luxury and comfort, making even the longest journeys enjoyable.

The 18-inch Salta wheels, designed for better traction, not only enhance the vehicle's performance but also its distinctive look. Unique design elements, such as AEV badges, complete the bold style of this edition, emphasizing its premium character.
