New 2025 GMC Sierra 2500HD SLT

Description for 2025 GMC Sierra 2500HD SLT Truck

The 2025 GMC Sierra 2500HD SLT blends heavy-duty performance with an array of advanced features tailored for capability, comfort, and modern connectivity. Powered by a robust 6.6L V8 engine paired with a 10-speed automatic transmission, this four-wheel drive truck is well-equipped to handle demanding tasks, whether towing, hauling, or navigating off-road terrain. The included 2-speed active transfer case, off-road suspension, Hill Descent Control, and the X31 Off-Road & Protection Package enhance trail readiness and stability under tough conditions.

This SLT trim is configured as a 4-door Crew Cab with a spacious and refined interior dressed in Jet Black leather. The cabin includes front bucket seats, a floor-mounted center console, and ventilated and heated seating for both front occupants. Heated second-row outboard seats are also provided. Convenience features such as keyless open and start, push-button start, and a power sliding rear window with defogger contribute to everyday usability. Ambient amenities like rain-sensing wipers, dual-zone automatic climate control, and a universal home remote further enhance the driving experience.

A wide selection of connectivity and infotainment technologies are integrated throughout. The 6-speaker audio system is upgraded to a Bose Premium 7-speaker sound system under the SLT Premium Package. Wireless Apple CarPlay and Android Auto are supported, and wireless charging is included for added convenience. Multiple USB ports, including charge-only and charge/data options, are distributed throughout the cabin, ensuring device support for all passengers.

From a visibility and safety standpoint, the Sierra 2500HD SLT is equipped with HD Surround Vision, Trailer Cam Provisions with Trailer Viewing Software, Rear Cross Traffic Alert, and Trailer Side Blind Zone Alert, all of which are enhanced by the Sierra HD Pro Safety Plus Package. The truck also features Adaptive Cruise Control, a Safety Alert Seat, Ultrasonic Front and Rear Park Assist, and LED lighting in the cargo area. Notably, the HD Rear Vision Camera has been deleted, likely due to overlap with the more advanced surround-view system.

Exterior appointments include 20-inch bright face wheels with dark painted pockets, chrome accents on the grille, deep-tinted glass, LED smoked amber roof marker lamps, and 6-inch rectangular chromed tubular assist steps. A spray-on bedliner with the GMC logo, LED cargo area lighting, rear wheelhouse liners, and multiple trailering aids ensure the truck is not only stylish but also highly functional. The Gooseneck/5th Wheel Prep Package and the Off-Road Suspension further add to its towing versatility and rugged performance.

Additional packages such as the SLT Convenience Package, SLT Preferred Package, and SLT Premium Package contribute to a higher tier of comfort, safety, and style within this configuration. Practical elements like all-weather floor liners, remote vehicle start, and an unauthorized entry theft-deterrent system are included to accommodate daily utility and security.
