Fuel stops, town runs and overnight parking all leave the bed of a F-150 2021-2027 sitting in the open, with tools and camp gear in plain sight.
The BAKFlip MX4 (GEN 3) is a hard folding cover with high-density polymer-reinforced aluminum top panels that are 22 percent stronger than the original MX4, rated for 400 lb of evenly distributed weight. Auto-latching panels secure it when closed, and revised EPDM perimeter seals and tight-fit clamps keep weather out.
It installs with a click-in mounting system and no drilling. Fold it against the cab for full bed access, drop it back down, and the load is covered again.
