      Secure and Organized Storage. If your Sierra’s factory rear underseat organizer doesn’t do it for you, you need this Underseat Storage with Lockable Lid in Black. This underseat storage case offers over 11,000 square inches of space and a lockable lid featuring two locking points. This design enables you to hold a wide variety of tools, equipment, and supplies in a completely secure manner. What’s more, this storage case is designed to conform to the shape of the space underneath your rear seat for a clean inconspicuous look.

      Legal Gun Storage. This underseat storage case also includes a pair of notched dividers made of rigid foam. These dividers provide the case with compartments for even more organizational options. More significantly, the dividers’ notched design works as a gun rack, permitting you to use this storage case as legal gun storage for all your hunting trips. Please note though those gun laws may vary from state to state, so always check local laws regarding gun storage.

      Tenacious Build Quality. This underseat storage case is precision-molded to exact measurements from high-quality polyethylene. This combination of quality materials and high-tech manufacturing produces a tenacious storage solution that fits your truck like a glove. Rounding out its construction is a standard black colorway to keep the case completely discreet.

      Simple Install Procedure.  This underseat storage case is designed to install into the space under your rear seats using factory mounting points. No additional drilling or other modifications are necessary although you might need to remove the brackets that hold the jack and jacking equipment. Other than this potential step, installation is a fairly simple procedure that’s completed using minimal tools.

      Application. This Underseat Storage with Lockable Lid in Black fits all 2019 to 2023 GMC Sierra 1500 Crew Cab models.
