This 2026 GMC Sierra 2500HD AT4 Crew Cab is presented in Onyx Black Paint and has been fitted with a CST Suspension 4 lift kit paired with CST 2.0 Dirt Series front and rear shocks, along with a four-wheel alignment, which gives the chassis added clearance without relying on a torsion bar drop arrangement. It rides on 22 Fuel Off Road FC847 Flux gloss black wheels with 37x12.50R22 Nitto Ridge Grappler tires, and the windows have been professionally tinted with a lifetime warranty. The exterior remains purposeful, with Roof Marker Lamps included in the equipment list, and the truck's proportions are further defined by the higher stance and the larger tire-and-wheel combination. This 2026 GMC Sierra 2500HD AT4 Crew Cab is powered and equipped for heavy-duty work with Federal Emissions Requirements, a 3.42 Rear Axle Ratio, a 220 Amp Alternator, and an Engine Block Heater. The GVWR of 11,350 lbs. places it within the expected range for a truck of this class, and the Exhaust Brake adds to its towing-focused hardware. A Winter Grille Cover is included as well, and the AT4 Preferred Package brings together the trim's core content without altering the truck's straightforward character. The body and chassis details remain consistent with a heavy-duty pickup intended for regular use under load. This 2026 GMC Sierra 2500HD AT4 Crew Cab includes a cabin specified with Leather Seats, Adaptive Cruise Control, Collision Warning, and a Head Up Display. The Technology Package adds additional driver-oriented equipment, while a Rear Camera Mirror is part of the available visibility features. Wi-Fi Hotspot and Premium Audio are also listed, giving the interior a mix of connectivity and sound equipment that fits within the truck's broader option set. The Crew Cab format provides the expected full-size rear seating area, and the AT4 treatment keeps the interior specification aligned with the rest of the truck. This 2026 GMC Sierra 2500HD AT4 Crew Cab carries the kind of equipment buyers usually look for in a heavy-duty pickup that will spend time on highways, job sites, and in trailer duty. The combination of the lift, larger wheel-and-tire package, and tinted glass changes the truck's appearance and ride height without altering the fact that it remains a 2500HD with the factory options documented above. Its listed hardware, including the emissions package, axle ratio, alternator, block heater, and camera and driver-assist features, gives a clear picture of the equipment on the truck as it sits.----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.
