2020 Sierra HD
2020 Sierra HD
More powerful than ever and packed with hardworking technology, the All-New 2020 Sierra HD is designed and engineered from the ground up to take on the most demanding jobs.
With more capability across the entire line-up, the All-New Sierra HD can tow heavy loads without breaking a sweat. Haul your boat out on the lake more easily than ever. Design starts with the 2500 Crew Cab 4WD with an impressive maximum towing of 18,500 lbs for conventional and fifth-wheel gooseneck.
The maximum gooseneck towing capability increases by 52% to a segment-leading 35,500 lbs —making the 2020 Sierra HD the most capable truck in the HD segment. Beyond increased capabilities, the new in-vehicle Advanced Trailering System and up to fifteen available exterior views† are designed to make hitching easier and driving with a trailer a more confident experience.
Built on the solid foundation of high-strength steel, the All-New Sierra HD delivers the strength to handle heavy-duty tasks. It’s engineered with seven different types of steel, with each gauge chosen to maximize capability for a truck that comes ready to work for years to come.
The Durabed of the All-New Sierra HD is the most functional bed in its class. Made with high-strength steel, the bed features 12 standard tie-downs, and offers LED cargo area lighting and a built-in 120-volt outlet with a larger cornerstep rear bumper and an all-new side BedStep between the cab and the rear wheel.
The All-New Sierra HD comes ready to work straight from the factory. It offers an integrated Power Takeoff (PTO) package on the Allison® transmission and dual alternators on both engine options to make it easy to power the accessories you need for commercial applications. It was also designed with lower bedside walls for more trailer clearance for fifth-wheel and gooseneck towing, and a modular front end to make mounting a snowplow easier than ever…and in Wisconsin, that’s definitely a bonus!
