Used 2019 Gmc Sierra Denali

This 2019 GMC Sierra Denali delivers the perfect balance of heavy-duty diesel capability and refined luxury, finished in striking Quicksilver Metallic over a Jet Black leather interior. Under the hood sits the legendary 6.6L Duramax turbo diesel V8 paired to the Allison 1000 6-speed automatic transmission, a combination known for effortless power, reliability, and serious towing confidence. This Denali stands tall with a lifted suspension and aggressive 20" aftermarket wheels wrapped in 35" tires, giving it a commanding presence that matches its performance. Whether you're hauling, towing, or cruising, trailering wiring provisions support conventional towing along with fifth wheel and gooseneck setups, making this truck as capable as it is impressive. Inside, luxury takes center stage with heated and cooled front seats, a power sunroof, and a premium Bose audio system. The 8" color touchscreen keeps everything at your fingertips with navigation and a backup camera, while advanced safety features like lane departure warning and forward collision alert add confidence on every drive. Powerful, bold, and exceptionally well-equipped, this Sierra Denali is built for drivers who want maximum capability without giving up comfort or style. A true diesel powerhouse with luxury credentials-available now at Cosmo Motors.
