GMC Sierra Tonneau Cover - Undercover - Flex - Black Textured - `19-`26 free shipping

The GMC Sierra Tonneau Cover - Undercover - Flex - Black Textured - `19-`26 is a state-of-the-art folding cover designed for the latest GMC Sierra models from 2019 to 2026. This cover seamlessly combines the robust security of a hard tonneau cover with the ease and functionality of a soft roll-up, providing you with the ultimate truck bed protection solution.

Crafted with top-tier materials, the UnderCover Flex Cover is built to resist damage from the elements, making it both durable and reliable. Its ultra-low profile design sits neatly inside the bed rails for a sleek appearance while offering full truck bed access when you need it. The design features integrated prop rods, allowing you to drive with the cover fully open. Additionally, the cover can be entirely removed in seconds without the need for any tools, giving you maximum versatility and ease of use.

  • Full access to truck bed with built-in prop rods.
  • Quick and easy removal; no tools required.
  • Secure design with plastic buckles and straps for partially open positioning.
  • Lighter, stronger FRP composite panels with higher dent resistance than aluminum.
