This 2026 GMC Sierra 2500HD AT4 Crew Cab is finished in Onyx Black Paint and fitted with a McGaughy's 4 lift kit, KG1 Forged 22 wheels in gloss black, Toyo 37X12.50R22 Open Country R/T Trail tires, and professionally installed tinted windows with a lifetime warranty. This heavy-duty pickup pairs those additions with the AT4 trim's more rugged presentation, while keeping the details straightforward and functional in appearance. This Sierra 2500HD also includes Adaptive Cruise Control, Collision Warning, Navigation, Leather Seats, Premium Audio, and a Wi-Fi Hotspot, bringing a mix of driver-assist and cabin technology to the interior. This 2026 model presents its modifications and factory equipment in a way that remains easy to identify without adding unnecessary complexity. This GMC Sierra 2500HD AT4 Crew Cab is powered and equipped with the kind of hardware expected from a three-quarter-ton truck, including a 220 Amp Alternator, a 3.42 Rear Axle Ratio, and Federal Emissions Requirements. This truck also includes an Exhaust Brake, which is a relevant part of its heavy-duty specification, along with an Engine Block Heater for cold-weather use. This Sierra 2500HD carries a GVWR of 11,350 lbs., giving a clear indication of its rated weight capacity. This 2026 GMC is also fitted with a Front License Plate Bracket and a Winter Grille Cover, both of which are part of the listed equipment. This Sierra 2500HD AT4 Crew Cab combines the elevated stance from the 4 suspension lift with the larger wheel-and-tire package in a way that changes the truck's proportions without altering its basic identity. This GMC uses the KG1 Forged wheels and Toyo all-terrain tires to fill the wheel openings with a taller, wider combination that matches the lifted ride height. This 2026 truck keeps the exterior treatment simple beyond the black paint and tinted glass, and the result is a clean presentation with clearly visible aftermarket and factory elements. This AT4's details remain practical and direct, with no added claims beyond the equipment listed on the vehicle. This 2026 GMC Sierra 2500HD AT4 Crew Cab places comfort and utility together with leather seating surfaces, premium sound, and connected features such as the Wi-Fi Hotspot and Navigation. This pickup also includes Adaptive Cruise Control and Collision Warning, which add to the list of onboard systems already specified for the truck. This GMC's interior equipment is matched by the heavy-duty mechanical content, including the alternator, exhaust brake, and axle ratio noted above. This Sierra 2500HD presents the listed options plainly, with the focus on the actual equipment rather than on any broader description of use or character.----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.
