New 2025 GMC Sierra 3500HD SLT

Description for 2025 GMC Sierra 3500HD SLT Truck

The 2025 GMC Sierra 3500HD SLT is a heavy-duty pickup truck designed for those who require both serious towing power and a premium interior experience. Powered by a 6.6L V8 engine paired with a 10-speed automatic transmission and a 4WD system, this truck is built to handle demanding loads and rugged terrain. It features the X31 Off-Road Package, which includes off-road suspension, hill descent control, skid plates, and twin-tube shocks to support performance beyond paved roads.

This Crew Cab configuration offers generous passenger space, enhanced by the comfort of Jet Black leather upholstery and heated and ventilated front seats. Rear seat passengers benefit from heated outboard seating positions. Front bucket seats and a floor-mounted center console contribute to a functional, driver-focused layout. The SLT trim includes a wide range of high-end appointments, such as a Bose Premium 7-speaker sound system, rain-sensing wipers, and wireless charging.

Technology is another strong point, with wireless Apple CarPlay and Android Auto compatibility integrated into the infotainment system. Multiple USB ports, including charge-only and charge/data options, are distributed throughout the cabin for convenience. Remote vehicle start, push-button ignition, and keyless open and start are standard, providing easy access and operation.

For towing and hauling, this Sierra 3500HD is equipped with the Gooseneck/5th Wheel Prep Package and includes trailer camera provisions, a bed view camera, and Trailer Side Blind Zone Alert. The suspension package and 2-speed active transfer case contribute to greater control under load. The 120-volt power outlets in both the bed and the instrument panel support worksite or tailgate utility. LED cargo area lighting and a spray-on bedliner with GMC branding protect and illuminate the truck bed.

Safety technologies are part of the Sierra HD Pro Safety Plus Package and include Rear Cross Traffic Alert, Ultrasonic Front and Rear Park Assist, a Safety Alert Seat, and Trailer Side Blind Zone Alert. The HD Surround Vision system enhances situational awareness during low-speed maneuvers, though the HD Rear Vision Camera is deleted as part of the configuration, likely in favor of the surround-view system.

Visually, this model presents with a Sterling Metallic exterior accented by chrome grille insert bars and 20-inch Bright Face wheels with dark painted pockets. The 6-inch rectangular chromed assist steps aid in cab access, and deep-tinted glass enhances privacy and sun protection. Functional additions like the power sliding rear window and electric defogger add convenience.

Packages such as the SLT Convenience, SLT Preferred, SLT Premium, and X31 Off-Road & Protection Package further enhance the vehicles capability and livability, offering bundled features like advanced trailering support, comfort upgrades, and added protection for off-road use.
