This 2025 GMC Sierra 3500HD AT4 Crew Cab is equipped with a 3 lift that has been leveled with Fox Shocks, along with Fuel wheels, Toyo tires, and additional modifications that include custom Elka shocks. This combination gives the truck a more deliberate ride height and a set of hardware choices that reflect attention to both stance and function without changing the underlying heavy-duty character of the chassis. This truck is finished in Sterling Metallic paint and carries the AT4 trim's darker, more utilitarian look, while the added suspension and wheel-and-tire package bring a more customized appearance to the body and fender openings. This 2025 GMC Sierra 3500HD AT4 Crew Cab includes Adaptive Cruise Control, Collision Warning, a Head Up Display, and a Rear Camera Mirror, along with the Technology Package. The cabin is fitted with Leather Seats, Premium Audio, a Wi-Fi Hotspot, and a Power Sunroof, and it also includes the AT4 Preferred Package and AT4 Premium Plus Package. This truck has a straightforward equipment mix that combines convenience, driver information, and interior appointments without straying from its work-focused foundation. This 2025 GMC Sierra 3500HD AT4 Crew Cab is also equipped with a 3.42 Rear Axle Ratio, a 220 Amp Alternator, an Exhaust Brake, and a Trailer Tire Pressure Monitor System. This truck includes an AT4 High Clearance Step, Roof Marker Lamps, a Winter Grille Cover, an Engine Block Heater, Federal Emissions Requirements, and a Front License Plate Bracket. These items add practical hardware and region-specific equipment to the build, and the heavy-duty electrical and towing-related components align with the rest of the truck's specification. This 2025 GMC Sierra 3500HD AT4 Crew Cab carries a GVWR of 12100 lbs. and presents itself as a heavy-duty diesel-oriented pickup with the kind of equipment expected on a well-optioned AT4. The factory and added components work together to create a truck that is ready for demanding use, with the suspension upgrades, wheel-and-tire package, and selection of trailering, convenience, and cold-weather equipment all listed plainly on the build.----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.
