2026 GMC Sierra 3500

This 2026 GMC Sierra 3500HD AT4 Crew Cab is fitted with a CST Suspension 4'' lift kit that uses CST 2.0 Dirt Series front and rear shocks and includes a four-wheel alignment, along with 22'' Fuel Off-Road FC865 Strike wheels in full gloss black, 37X12.50R22 Nitto Ridge Grappler tires, and professionally installed window tint with a lifetime warranty. Those additions sit under a heavy-duty truck that already has the AT4 trim's more rugged orientation, while still keeping the details straightforward and functional. The combination of the lifted stance, large-diameter wheels, and wide tires gives the truck a more customized road presence without changing the fact that it remains a Sierra 3500HD built for demanding use.

This Sierra 3500HD AT4 Crew Cab is equipped with Adaptive Cruise Control, Collision Warning, and Navigation, along with Wi-Fi Hotspot connectivity and Premium Audio. The cabin also includes Leather Seats, giving the interior a more finished feel alongside the truck's technology features. The available systems are arranged around everyday driving and long-distance travel, with the navigation and connectivity functions keeping information and communications within reach while the driver-assistance equipment adds another layer of support during highway use.

This 2026 GMC Sierra 3500HD AT4 Crew Cab carries the proportions and hardware expected of a full-size heavy-duty pickup, with the Crew Cab body providing the larger passenger area associated with this body style. The AT4 trim adds a distinct appearance and equipment set within the Sierra lineup, and this example has been further outfitted with the suspension and wheel-and-tire combination already noted. The 4'' lift changes the truck's stance without relying on exaggerated styling details, and the gloss black 22'' wheels paired with the 37'' Nitto tires give the chassis a more substantial footprint while keeping the description grounded in what is physically present.

This 2026 GMC Sierra 3500HD AT4 Crew Cab offers a blend of comfort, driver aids, and specialty equipment that is described by its listed options rather than by assumptions about how it will be used. The leather-trimmed seating, premium sound system, wireless connectivity, and navigation all support the interior side of the truck, while the added suspension components, wheel package, tire size, and tinted glass define much of the exterior treatment. Each element is visible in the build as listed, and the truck's equipment can be read directly from those features without adding claims beyond them.----We've built an unmatched reputation over the last two decades for customizing and selling thousands of the highest quality used vehicles in the country.
