GMC Sierra 2500 HD Tonneau Cover - UnderCover Flex Folding, Black Textured (2020-2026). A hard-folding, low-profile bed cover delivering security and quick access.
UnderCover Flex uses FRP composite panels for hard-cover strength with tri-fold convenience. It mounts inside the bed rails for a low profile, channels water with rubber seals and drain tubes, and can be driven fully open using built-in prop rods. Tool-free removal, clamp-on installation, and buckles/straps for a partially open position round out a durable black textured design. Backed by a 3-year warranty.
