GMC Sierra MultiPro™ Tailgate

For your ultimate convenience on the job, the GMC Sierra 1500 is available with a six-function MultiPro™ Tailgate – the world’s first tailgate of its kind! This incredibly innovative feature makes it easier than ever to load and unload your Sierra truck bed with six different functions:

  1. Primary Gate: There are three ways to open the primary gate: using your GMC key fob’s power release button, opening it from inside your truck, or by pressing a button on the gate itself.
  2. Primary Gate Load Stop: When the primary gate is open, the convenient load stop ensures nothing will slide out of the truck bed.
  3. Easy Access: Fold down the inner gate for uninhibited loading and unloading of the truck bed.
  4. Full-Width Step: When needed, you can fold the inner gate into a large, sturdy step, allowing you to have more confident footing when you enter and exit the bed.
  5. Inner Gate Load Stop: In addition to the primary gate load stop, the inner gate also features a load stop to help prevent second-tier tools and equipment from sliding out.
  6. Inner Gate with Work Surface: Finally, the inner gate can be converted into a work surface. When you’re out on the job site and away from your desk, this creates a space to easily take notes, lay down blueprints, and more. It also serves as a second-tier loading feature.
