This Dark Slate Metallic 2017 GMC Sierra 2500HD Denali Crew Cab is a heavy duty workhorse that combines massive towing capability with the luxury of a high end SUV. With 161,018 miles, this truck has proven its durability and remains a top choice for those who need serious power for hauling or long distance towing. The 2017 model year was a major milestone for the Sierra HD, introducing the redesigned 6.6L Duramax Turbo Diesel engine which delivered a then class leading 445 horsepower and a staggering 910 lb ft of torque. Mated to the legendary Allison 1000 6 speed automatic transmission, this powertrain is built for longevity and effortless performance under heavy loads. As a Denali trim, the interior is packed with premium features including perforated leather appointed heated and ventilated front bucket seats and a heated steering wheel. The cabin is designed for both comfort and utility, featuring a large center console with wireless charging and a Bose premium sound system. Safety and driver assistance tech are also front and center, with standard features like Forward Collision Alert, Lane Departure Warning, and the Safety Alert Seat. The exterior is instantly recognizable by the iconic Denali chrome grille, 20 inch chrome wheels, and the functional hood scoop that was new for 2017 to improve engine cooling. Given the mileage, this truck has reached a point where consistent maintenance is the key to another 100,000 miles. At the 150k to 160k mark, it is recommended to ensure the cooling system has been flushed and the transmission and transfer case fluids have been serviced. This Sierra 2500HD also features the Digital Steering Assist system, which makes maneuvering this large crew cab much easier in tight spaces or when backing up a trailer. With a conventional towing capacity of up to 14,500 lbs and a fifth wheel rating even higher, this Dark Slate Denali is ready to tackle the toughest jobs while keeping you in total comfort.
