UnderCover Ultra Flex Hard Folding Bed Cover for 2017-2026 Ford F-250/F-350 Super Duty (6.8ft Bed) - UX22021
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2017-2026 Ford F-250 and F-350 Super Duty models with a 6.8-foot bed across all trims including XL, XLT, Lariat, King Ranch, Platinum, and Limited.
The UnderCover Ultra Flex is a premium hard-folding tonneau cover engineered for truck owners who demand heavy-duty protection without sacrificing a sleek, low-profile aesthetic. Constructed with a high-density polymer core sandwiched between aircraft-grade aluminum panels, this cover provides a 400-lb. weight capacity (evenly distributed) and a resilient matte black finish. The underside features carpeted underpanels, providing a finished OEM look and a soft-impact layer to protect your cargo from shifting.
Security and weather resistance are prioritized with a patented rail and clamp system. Automatic slam latches secure every panel as they close, while upgraded seals and a dual-action tailgate seal ensure moisture, dust, and debris stay out of the bed. For full-bed utility, the cover folds completely to the cab and secures with prop rods, allowing you to drive safely at highway speeds with 100 percent bed access. Installation is efficient with the tool-free Tip-and-Click mounting system, typically taking under 30 minutes.
- Manufacturer Part Number: UX22021
- Premium matte black aluminum surface with high-density polymer core
- 400-lb. weight capacity (evenly distributed)
- Low-profile design sits nearly flush with bed rails
- Integrated luminous LED bed rail light for nighttime visibility
- Tested for extremes from -40°F to 180°F and 95% humidity
- Dual-action tailgate seal allows operation with cover open or closed
- Proudly assembled in the USA
- 5-year manufacturer warranty
