2026 GMC Sierra 3500

This 2026 GMC Sierra 3500HD AT4 Crew Cab has been fitted with a CST Suspension 4'' lift kit that combines fabricated upper control arms, CST 2.5 adjustable remote-reservoir shocks at both ends, and a four-wheel alignment, along with 22'' full-gloss black Fittipaldi off-road wheels, LT325/50R22 Nitto Ridge Grappler tires, and professionally installed window tint backed by a lifetime warranty. It is equipped with Adaptive Cruise Control, Leather Seats, Wi-Fi Hotspot, Premium Audio, Collision Warning, and Navigation, bringing together the heavy-duty GMC cabin and a set of added components that are described in straightforward terms in the build.

This Sierra 3500HD AT4 Crew Cab is built on GMC's heavy-duty platform and carries the AT4 trim's off-road-oriented character in a full-size crew cab body. The truck's proportions give it the space expected from a 3500HD while keeping the interior and exterior presentation focused on utility and durability. With the lifted stance and the larger tire-and-wheel package, the body sits higher than a stock truck, and the suspension and alignment work are part of the same installed package rather than isolated cosmetic changes.

Inside, the leather seating adds a more finished feel to the cabin, while the available technology supports daily use and longer trips alike. Navigation is built in for route guidance, and the Wi-Fi hotspot provides an onboard data connection. Premium audio is included for the sound system, and the driver-assistance equipment adds Adaptive Cruise Control and Collision Warning to the list of factory options. These features are presented without embellishment, and they fit the way this truck is equipped as a high-spec heavy-duty model.

The exterior details are simple to read and easy to identify. The black 22'' Fittipaldi wheels pair with the Nitto Ridge Grappler tires, and the sizing gives the truck a more substantial presence without changing the basic purpose of the Sierra's HD chassis. The tinted glass finishes off the side profile and reduces visibility into the cab, while the suspension hardware underneath reflects a more involved build than a cosmetic lift alone. This 2026 GMC Sierra 3500HD AT4 Crew Cab combines those installed parts with the standard strengths of the GMC nameplate and the equipment listed above.----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.
