The UnderCover Flex folding bed cover, part number undFX11022, combines the security of a hard folding tonneau cover with the convenience of a soft roll-up design. It is engineered for 2019-2026 Chevrolet Silverado and GMC Sierra models with the new body style and a 5.8-foot bed, including Crew Cab and extended cab configurations. The cover fits trucks with or without the MultiPro or Multi-Flex tailgate, but it is not compatible with the CarbonPro bed. Verify your truck’s body style before purchase, especially for 2019 models, which may be available in new body style, Legacy, or Limited configurations.
The low-profile design sits inside the bed rails for a clean, streamlined appearance while preserving bed access. Built-in prop rods secure the cover in the fully open position, allowing the truck to be driven with the bed uncovered. Plastic buckles and straps secure the panels in a partially open position, providing flexible cargo coverage when full bed access is not required. The FRP composite panels are lighter, stronger, and more resistant to dents than traditional aluminum panels, helping the cover withstand demanding weather and everyday use.
Rubber seals and drain tubes help channel water away from the cargo area and out of the truck bed. The easy clamp-on installation requires no drilling, and the complete cover can be removed in seconds without tools when maximum hauling capacity is needed. The UnderCover Flex offers a practical combination of security, weather resistance, versatile access, and straightforward installation, backed by a 3-year warranty.
