2021 is all set to witness the Silverado 3500 H, best in class, up to 36,000 pounds of maximum towing capacity.  The Silverado HD gets substantial updates and augmentations for the 2021 model, which has built upon the strength of Chevrolet’s heavy-duty truck lineup and trailering technology in order to magnify its towing leadership.

From moving equipment to the job site to towing a prized possession, No trucks work harder than Silverado HD. does  For this latest upgrades, the Chevrolet engineers augmented the max towing capacity 500 pounds for the best-in-class max tow rating of up to 36,000 pounds (16,329 kg) on Silverado HD.  These Hardware updates and packaging changes to the wheels assisted to achieve the new tow rating, which is specialized in SAE J2807 standards.

This time, the Silverado HD comes up with the best towing technology, proposing 15 exclusive camera views and 8 cameras for towing assurance.  It further splits itself from the competition with enhanced trailering technology for 2021 including:

  • Trailer Length Indicator: When making a lane-change maneuver with the activated turn signal, a red overlay is displayed on the center console screen, hence, helping the other available vehicles at that time.
  • Jack-Knife Alert: it Tracks the position of the compatible trailer and provides an alert if a potential jack-knife situation is looming.
  • Cargo Bed View enhancement: new available Cargo Bed Zoom View and Bed Hitch Guidance benefit in aligning and hooking up a gooseneck/fifth-wheel trailer.
  • Rear Trailer View now features guidelines and Trailer-Angle Indicator: Heightened to comprise assisting guidelines when backing a companionable trailer into place. A Trailer-Angle Indicator displays the relationship between the truck and trailer.
  • Rear Side View enhancement: it provides a split view inclined on the trailer’s angle, of the left and right sides of the truck and harmonious trailer. This view was earlier only be obtained while driving forward, but now being offered in Reverse for improved and better visibility.
