2026 GMC Sierra 3500

This 2026 GMC Sierra 3500HD AT4 Crew Cab is equipped with a CST Suspension 4'' lift kit that uses CST 2.0 Dirt Series shocks at both ends and includes a four-wheel alignment, along with 20'' Fuel Off-Road D675 Blitz gloss black wheels, 37x12.50R20 Nitto Ridge Grapplers, and professionally installed window tint with a lifetime warranty. This heavy-duty GMC also includes Adaptive Cruise Control, Leather Seats, Wi-Fi Hotspot, Premium Audio, Collision Warning, and Navigation, giving it a mix of towing-focused hardware and familiar in-cab conveniences.

This Sierra 3500HD AT4 is built around GMC's heavy-duty Crew Cab format, with the larger cabin and AT4 trim combining practical passenger space with a more rugged presentation. Its stance is altered by the CST suspension components, and the upgraded wheel-and-tire package fills the wheel openings with a taller profile than the factory standard. The window tint adds a finished look to the glass while also keeping the exterior details consistent from side to side.

Inside, the cabin is trimmed with leather seating surfaces and supported by the kind of equipment that makes long drives and job-site travel easier to manage. The premium audio system is included, as is the Wi-Fi hotspot, which allows connected devices to stay online when service is available. Navigation is part of the equipment list as well, and the controls and displays are arranged in a way that fits the straightforward character of the truck.

This Sierra 3500HD AT4 also includes Adaptive Cruise Control and Collision Warning, two driver-assist features that add another layer of monitoring during highway use and in traffic. The truck's size, chassis strength, and AT4 trim level place it among GMC's more capable heavy-duty offerings, while the listed suspension, tires, and wheel combination give it a more specialized appearance without changing the fact that it remains a work-oriented pickup at its core.----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.
