The BAKFlip MX4 (GEN 3) from BAK is the ultimate upgrade to your Ford F-150's truck bed. Designed for model years 2021 through 2023, this hard folding tonneau cover combines strength, security, and sleek styling to protect your cargo and enhance your truck's appearance. Constructed primarily from high-density polymer-reinforced aluminum, the top panels and side rails are 22 percent stronger than previous models, providing increased durability for demanding conditions. Its precision-engineered aluminum frame ensures a perfect fit, sitting flush with your truck's bed rails for a low-profile, integrated look. The textured matte black finish adds a stylish touch that resists scratches and weathering, maintaining a sharp appearance over time. The MX4's innovative design allows for quick, one-person installation thanks to the new click-in system, reducing setup time by approximately 12 percent compared to older models. Its folding mechanism provides full bed access when needed, folding against the cab without hindering rear visibility or tailgate operation. The cover features a comprehensive integrated water drainage system, reinforced with revised EPDM rubber perimeter seals and tight-fit clamps to provide superior weather resistance and prevent seepage, even in heavy rain or snow. An extra-long dual-action tailgate seal enhances protection at the tailgate, ensuring your cargo remains dry and secure. Security is a key aspect of the MX4 design, with re-engineered lock components for improved resistance to forced entry, complementing BAK's patented auto-latching system that automatically secures the cover when closed. The design also incorporates premium rubber bumpers to protect your truck’s cab when the cover is folded upright. The sleek, textured black finish extends across all components, giving your truck a modern, cohesive appearance whether the cover is open or closed. With a 400-pound weight capacity and a five-year warranty, the BAKFlip MX4 (GEN 3) is built to withstand rigorous use while providing reliable bed protection and easy operation. Proudly assembled in Missouri, this cover is an excellent choice for truck owners seeking durability, security, and style in one package.
