Building upon the strength of Chevrolet’s heavy-duty truck lineup, the Silverado HD receives significant updates and enhancements for the 2021 model, including an available max tow rating of up to 36,000 pounds1 and a multitude of trailering technology features to expand its towing leadership.
Increased Max Towing Capability
No trucks work harder than Silverado HD, from moving equipment to the job site to towing a prized possession. For 2021, Chevrolet engineers increased the max towing capacity 500 pounds for an available best-in-class max tow rating of up to 36,000 pounds on Silverado 3500 HD Work Truck, Regular Cab, dual-rear-wheel, two-wheel-drive models equipped with the 6.6L Duramax diesel and 10-speed Allison transmission and Max Tow Package. Hardware updates to the suspension and packaging changes to the wheels helped achieve the new tow rating, which is certified to SAE J2807 standards.
Enhanced Trailering Tech for More Views and Towing Confidence
The Silverado HD sets the bar for towing technology, offering up to a class-leading available 15 unique camera views2 and eight cameras for towing confidence. For 2021, Chevrolet further separates itself from the competition with enhanced trailering technology also available on the 2021 Silverado 1500, including:
- Trailer Length Indicator2: When making a lane-change maneuver with the turn signal activated, a red overlay twice the length of the compatible trailer is shown on the center console screen, which can help show when other vehicles are present.
- Jack-Knife Alert2: Tracks the position of the compatible trailer in relation to the vehicle and provides an alert if a potential jack-knife situation is imminent.
- Cargo Bed View enhancement: Cargo Bed Zoom View and Bed Hitch Guidance are now available, which help to align and hook up a gooseneck/fifth-wheel trailer.
- Rear Trailer View now features guidelines and Trailer-Angle Indicator2: Enhanced to include assisting guidelines when backing a compatible trailer into place and a Trailer-Angle Indicator shows the relationship between the truck and trailer3.
- Rear Side View enhancement2: Provides a split view, automatically biased based on the trailer’s angle, of the left and right sides of the truck and compatible trailer. This view was previously only available while driving forward and is now available in Reverse for better visibility when positioning a trailer.
Special Editions
Chevrolet trucks have a long tradition of offering a variety of special editions to meet customers’ interests and demands, and for 2021 the Silverado HD welcomes four unique versions to the HD lineup.
- Carhartt Special Edition: The Carhartt Special Edition is offered exclusively on the LTZ and features all-weather floor liners with the Carhartt badge, along with exclusive two-tone Jet Black and Carhartt Brown perforated front and rear leather seating surfaces featuring unique stitching and Carhartt embroidered headrests.

- Midnight Edition: Available on black LT and LTZ trims, Midnight Edition offers an intimidating blacked-out appearance from tip to tail, including the grille bar, grille inserts, skid plate, Silverado badging and standard black 18-inch aluminum wheels with aggressive mud-terrain tires, or available black 20-inch wheels.
