BAK Industries BAKFlip MX4 Hard Folding Tonneau Cover for 2004-2014 Ford F-150 (5.5ft Short Bed)

The BAKFlip MX4 448309 Hard Folding Tonneau Cover delivers premium cargo security, heavy-duty utility, and complete weather resistance for 2004–2014 Ford F-150 pickup trucks equipped with a 5.5-foot short bed (5' 7" bed box).

Constructed from heavy-gauge aluminum panels built over a high-density solid foam core, this cover supports up to 400 lbs. of evenly distributed weight while maintaining a ultra-sleek, low-profile appearance.

The premium matte black powder-coat finish is engineered specifically to prevent UV degradation, scratches, and severe scuffing encountered under demanding Canadian off-road and winter road conditions. Automotive bed protection specialists emphasize that the MX4’s dual-action tailgate seal permits independent tailgate operation, allowing you to open or shut the tailgate freely without raising the rear cover panel.
