The UnderCover SwingCase fits the 1999-2006 GMC Sierra 1500 driver side bed and delivers lockable, swing-out storage that keeps your gear within arm's reach.

Install Difficulty: DIY
Bolts to the driver side bed with included hardware; typically installs in 20-30 minutes with hand tools.

Product Overview

The SwingCase is a custom-fit truck bed storage box molded from lightweight, high-impact ABS plastic. Pull the quick-release latch and the case swings out to the tailgate, so you never climb into the bed to grab your gear.

A moisture seal keeps contents dry, and the lockable lid secures tools, recovery straps, or jobsite essentials. It mounts on the driver side of your Sierra 1500 bed and works alongside any tonneau cover.
