Used 2023 GMC Sierra 3500HD Denali

Some trucks are built for heavy work. Others are built to do it with authority. The 2023 GMC Sierra 3500HD Denali brings both together with massive Duramax diesel torque, premium Denali craftsmanship, and serious towing capability designed for drivers across Nanaimo and Vancouver Island who demand the very best from their truck.

At the heart of this Sierra sits the legendary 6.6L Duramax Turbo Diesel V8 delivering 445 horsepower and an incredible 910 lb ft of torque. Paired with a heavy duty 6 speed automatic transmission, this powertrain is engineered for hauling equipment, towing large trailers, or confidently managing demanding workloads across Vancouver Island highways and job sites. A two speed active electronic Autotrac transfer case provides dependable 4X4 capability when traction is needed, while the integrated trailer brake controller and trailer-ready systems make towing easier and more controlled. The truck rides on LT275 65R20 all terrain tires that provide strong traction and stability for highway travel, gravel roads, or demanding worksites.

The exterior reflects Denali level refinement while maintaining heavy duty truck presence. Polished 20 inch multi dimensional aluminum wheels give the Sierra a commanding stance while deep tinted glass adds comfort and privacy. LED signature taillamps provide a modern lighting signature, and the GMC MultiPro tailgate offers six functional access and loading positions to make loading tools, gear, or equipment easier. Rear wheelhouse liners help protect the bed while maintaining a clean and durable appearance.

Inside, the Denali interior blends strength with luxury. A power adjustable 10 way driver seat with lumbar support ensures long distance comfort whether commuting from Parksville to Nanaimo or heading toward Victoria with a trailer in tow. Wireless Apple CarPlay and Android Auto allow seamless smartphone integration, while wireless phone charging keeps devices powered without cables. A Wi Fi hotspot keeps passengers connected on longer drives, supported by multiple USB ports throughout the cabin for added convenience. The rear sliding power window with defogger improves airflow and visibility when towing or hauling equipment.

Advanced safety and driver support systems reinforce confidence behind the wheel. Automatic Emergency Braking, Forward Collision Alert, and Following Distance Indicator help monitor traffic conditions ahead, while IntelliBeam automatic high beams improve nighttime visibility on darker Vancouver Island highways. Teen Driver technology allows configurable driving settings and provides a report card for new drivers when needed.
