UnderCover 19-20 Chevy Silverado 1500 6.5ft Ultra Flex Bed Cover - Matte Black Finish

Total Access. Patented Security. Ultra Protection. The RealTruck® UnderCover® Ultra Flex hard-folding tonneau cover is built stronger and more durable, engineered for heavy-duty use with a sturdy, premium-grade matte black aluminum surface and a high-density polymer core. Its low-profile design sits nearly flush with the bed rails for a sleek appearance and up to 400 lbs. of weight capacity (evenly distributed). With ultra details, inside and out, the Ultra Flex’s underside looks just as good as its top. The smooth, matte black finish delivers a refined look, while the exclusive soft-impact underside adds a padded layer of protection for shifting cargo. The Ultra Flex fits tighter to keep water out. Upgraded seals and all-new tight-fit clamps provide state-of-the-art weather protection, keeping out water, dust, and debris—even in harsh conditions. Security is a hallmark of any high-end tonneau cover, and the Ultra Flex delivers. With a patented rail and clamp system featuring automatic slam latches, the cover automatically locks down every panel when closed to keep gear secure and out of sight—that’s patented security you can trust. The RealTruck UnderCover Ultra Flex hard-folding tonneau cover delivers 100 percent bed access—all the time. Simply fold the cover to the cab, secure it in place, and safely drive with the cover fully open. When closed, the slam latches reengage automatically. Installation is fast and straightforward with UnderCover’s all-new click-in design. The redesigned Tip-and-Click mounting system requires no tools, no hassle, and installs in under 30 minutes. Proven for extremes from Alaska to Florida, Ultra Flex has been tested in harsh conditions ranging from -40 to 180F and up to 95 percent humidity. It’s also been tested for 7,500 hours to reliably perform for over a decade of driving. Backed by a 5-year warranty, the Ultra Flex is tough enough for the job site, sleek enough for daily driving, and secure enough to protect what matters.

Protect your truck bed with the UnderCover Ultra Flex hard-folding tonneau cover, part number undUX12023. Designed for the 2019-2026 Chevrolet Silverado and GMC Sierra 1500 with the new body style and a 6-foot 7-inch bed, this cover fits standard, extended, and crew cab configurations with or without the MultiPro or Multi-Flex tailgate. It does not fit trucks equipped with the CarbonPro bed. Before ordering a 2019 model, verify that your truck is the new body style rather than the Legacy Chevrolet or Limited GMC version.
The Ultra Flex combines a premium-grade matte black aluminum surface with a high-density polymer core for dependable heavy-duty performance. Its low-profile design sits nearly flush with the bed rails for a clean appearance, while the soft-impact underside and carpeted underpanels help protect cargo and provide a finished OEM-style look.

The cover has been tested from -40 to 180 degrees Fahrenheit and in up to 95 percent humidity, along with 7,500 hours of durability testing.
A patented rail and clamp system with automatic slam latches secures each panel when the cover is closed. The hard-folding design provides 100 percent bed access by allowing the panels to fold toward the cab and remain secured while driving. Integrated bed rail lighting improves visibility in the cargo area, and the redesigned Tip-and-Click mounting system supports one-person installation in under 30 minutes without specialized tools. Proudly assembled in Missouri and backed by a 5-year warranty, the UnderCover Ultra Flex delivers reliable bed protection, convenient operation, and a sleek matte black finish for daily driving or demanding work use.
