GMC MultiPro™ Tailgate

Tackle a wider variety of tasks with the available six-function MultiPro™ Tailgate. Thanks to the following functions, you’ll be able to load and unload large items more efficiently than ever:

  • Power Release Button – With the touch of a button on your GMC key fob, open the primary gate.
    • Primary Gate Load Stop – When engaged, this function prevents cargo from sliding out of the truck bed while the primary gate is open.
  • Folding Inner Gate – Load and unload the truck bed more easily with the inner gate folded down. For better footing, the inner gate can also fold into a step.
  • Inner Gate Load Stop – Prevent second-tier tools and equipment from sliding with the inner gate engaged. The inner gate can also be converted into an additional work surface or a second-tier loading surface.
