The Sierra 2500HD arrives finished in Black with the Signature Chrome Denali Grille, establishing authority on any jobsite or street. Its aggressive exterior styling is matched by thoughtful details like the spray-on bedliner with Denali logo, LED cargo lighting, and polished exhaust tip. Rain-sensing wipers and fully automatic headlights respond to changing conditions without your input.
Inside, the cabin reflects Denali-level refinement. Genuine wood dashboard and door panel inserts complement the leather-appointed seats. Heated steering wheel, wireless phone projection, and wireless charging pad integrate modern conveniences throughout the cabin. The dual-zone automatic climate control keeps all occupants comfortable, while the overhead console and floor-mounted center console provide practical storage solutions.
This truck's trailering capabilities are comprehensive. The integrated trailer brake controller, hitch guidance with hitch view, and in-vehicle trailering system app give you control and confidence when towing. Trailer side blind zone alert and rear cross traffic alert add layers of awareness. The 220-amp alternator ensures sufficient electrical capacity for your demands.
Capability extends to all-terrain performance with the X31 Off-Road Package, 2-speed active transfer case, and hill descent control. Electronic stability control, traction control, and the off-road suspension work together to maintain composure in varied conditions. The 4-wheel disc brake system with ABS provides confident stopping power.
On-road safety is equally prioritized with forward collision alert, automatic high-beam management, and ultrasonic front and rear park assist. OnStar and GMC Connected Services provide emergency communication and vehicle diagnostics. Multiple airbags, including overhead protection, front side-impact, and occupant-sensing technology, form a comprehensive restraint system.
With 49,915 miles, this Denali has been properly maintained and remains well within the lifespan of this durable platform. Whether your needs lean toward work, towing, or weekend adventure, the Sierra 2500HD Denali delivers the performance, capability, and refinement that justify its standing in the premium heavy-duty truck market.
