2024 GMC Sierra HD AT4X: The Ultimate Off-Road Pickup with 18,500-pound Towing Capacity

The GMC Sierra HD is a full-size pickup truck that offers powerful performance, advanced technology, and premium comfort. The Sierra HD is available in six trim levels: Pro, SLE, SLT, AT4, Denali, and Denali Ultimate. The Sierra HD can tow up to 36,000 pounds and haul up to 7,442 pounds, depending on the configuration.

The Sierra HD is getting ready for a new off-road variant for the 2024 model year, and some leaked details have revealed the changes that are coming. The AT4X trim level is a more extreme version of the AT4 trim level, featuring a factory-installed 1.5-inch suspension lift, 35-inch Goodyear tires, a rear e-locking differential, and Multimatic DSSV dampers. The AT4X trim level also has an exclusive Obsidian Rush interior with leather seats and wood trim.

The 2024 GMC Sierra HD AT4X is expected to debut in late 2023 or early 2024, along with the rest of the updated Sierra HD lineup. The new Sierra HD AT4X will offer more off-road capability and appeal to customers who are looking for a rugged and adventurous truck. The Sierra HD AT4X will also benefit from the enhanced turbocharged power and trailering technologies of the Sierra HD.
