The BAK BAKFlip MX4 is a hard-folding aluminum tonneau cover for the 2008-2016 Ford F-250/F-350 Super Duty with the 8ft bed. Its heavy-duty aluminum top panels are reinforced with high-density polymer cores for a 22 percent strength increase over the original MX4, and a patented automatic latching system secures the cover when it is closed. EPDM perimeter seals, tight-fit clamps and a dual-action tailgate seal keep water out, and the panels fold flush against the cab for full bed access. It installs on the factory bed with no drilling.
