The truck's Duramax diesel engine pairs with a 10-speed automatic transmission and 4WD to deliver the towing and hauling capability expected of a heavy-duty pickup. The Gooseneck/5th Wheel Prep Package provides the infrastructure for serious trailering applications, while the integrated Trailer Cam system and trailer tire pressure monitoring sensors offer confidence during towing operations.

Technology integration runs throughout this truck's cabin. The 15-inch head-up display projects key information directly into your line of sight, reducing distraction while keeping essential data visible. The HD Surround Vision system, rear cross traffic alert, and ultrasonic front and rear park assist work together to enhance awareness and parking precision. Wireless charging, dual USB charging ports, and 120-volt power outlets throughout the cabin keep devices powered and accessible.

The X31 Off-Road Package equips this Sierra with dedicated suspension and hill descent control, expanding its capabilities beyond paved surfaces. The 2-Speed Active Transfer Case provides selectable four-wheel drive modes to adapt to changing conditions, whether tackling rugged terrain or returning to standard driving.

Interior appointments reflect Denali Ultimate-level detailing. Full grain leather seat trim covers heated and ventilated front seats with 16-way power adjustment and lumbar support. Heated rear outboard seats extend comfort to all passengers. The leather-wrapped steering wheel includes heating capability, while the power sunroof adds openness to the cabin environment.
