The Denali Ultimate trim elevates every detail. The signature Denali Ultimate grille wears Vader Chrome, while the spray-on bedliner bears the GMC logo. Inside, full grain leather wraps the seating surfaces, and genuine wood accents appear on the dashboard and door panels. Heated and ventilated front seats with power adjustments ensure comfort across any season, while the heated second-row outboard seats extend that luxury to your passengers.

Technology seamlessly integrates into daily driving. The premium GMC infotainment system connects with wireless phone projection, so your device works with you rather than against you. A 15-inch head-up display puts critical information directly in your line of sight. The bed view camera with trailer camera provisions and Hitch Guidance makes connecting your equipment straightforward and secure.

Trailering capability stands as a defining strength. The ProGrade Trailering System manages weight distribution and brake coordination intelligently. Trailer tire pressure monitor sensors keep you informed, while the in-vehicle trailering app provides real-time data and guidance. Trailer side blind zone alert adds another layer of awareness when maneuvering in tight spaces.

Safety runs throughout this truck's design. Automatic emergency braking, forward collision alert, and front pedestrian braking work together to prevent accidents before they happen. The safety alert seat provides haptic feedback to reinforce warnings. Ultrasonic park assist and rear cross traffic alert make tight parking situations manageable, while the auto-dimming rearview mirror with integrated camera keeps your view clear.

The Upfitter Switch Kit opens possibilities for customization. Five configurable circuits—three rated for up to 30 amps and two for 20 amps—provide the electrical backbone for aftermarket accessories. Whether you're outfitting this truck for work or specialized equipment, the infrastructure is already in place.
