Impex GMC – Why Roanoke, VA, Weekend Warriors Choose the 2026 GMC Sierra 2500 HD AT4X

The 2026 GMC Sierra 2500 HD AT4X is built for drivers who expect their truck to be as confident crawling over trail obstacles as it is towing a full work trailer. With a factory-installed 1.5-inch lift, Multimatic® DSSV dampers, and an arsenal of protective skid plates, the AT4X turns rugged routes into rewarding escapes—without sacrificing the refined cabin and technology you count on during the week. If your plans range from hauling a side-by-side into the mountains to backing a boat down a tight launch, this trim’s blend of hardware and high-end comfort pays dividends every mile.

Inside, the Obsidian Rush interior elevates every excursion with full-grain leather seating, technical-grain leather accents, and authentic Vanta ash wood. Long days are easier with 16-way heated and ventilated power front seats with a massage feature, while the available 15-inch Head-Up Display can project key metrics, like speed and incline, into your line of sight. Technology takes towing to the next level with available up to 14 camera views—think Transparent Trailer View for lane changes and HD Surround Vision for navigating narrow switchbacks or crowded marinas. The available Duramax® 6.6L Turbo-Diesel V8 with a 10-speed automatic underpins the confidence to crest steep grades with a trailer and descend with composure.

• Suspension: Multimatic® DSSV dampers and a factory 1.5-inch lift improve control and clearance on tough terrain.
• Tires: 35-inch Goodyear® Territory MT tires add bite in mud, sand, and rock.
• Protection: Larger steel transfer case skid plate and front aluminum skid plate help guard critical components.
• Traction: Rear electronic-locking differential helps manage power delivery when wheels are off-camber, or surfaces are loose.
• Awareness: Available up to 14 camera views, including Transparent Trailer View, supports safer maneuvering.

Frequently Asked Questions:

What makes the AT4X different from the AT4?

AT4X adds a factory lift, Multimatic® DSSV dampers, a rear electronic-locking differential, larger protective skid plates, and 35-inch Goodyear® Territory MT tires. Inside, it features the Obsidian Rush interior with full-grain leather and available massage front seats for a more indulgent, adventure-ready feel.

Can I outfit the AT4X for overlanding?

Yes. Many drivers pair the AT4X’s off-road chassis with accessories like bed-mounted racks, integrated lighting, and the MultiPro™ Tailgate’s versatile positions for loading camp gear. The available AT4X AEV Edition adds stamped steel bumpers and more robust skid plates for extra trail assurance.
