BAK Industries BAKFlip MX4 448311 is a matte-finish hard folding tonneau cover for the 2008-2016 Ford F-250 and F-350 Super Duty with the 8' long box, and RealTruck's application line for this part number reads 2008-2016 Super Duty, 8' bed. An 8' box is a lot of unprotected real estate on a work truck, and the MX4 is the version of that answer built to be beaten on.
MX4 sits a tier above the aluminum G2 series. The top panels are high-density polymer-reinforced aluminum instead of plain aluminum skin, and BAK rates the current generation panels as 22 percent stronger than the original MX4. The whole cover wears a textured matte black surface - top, rails, and hardware - so it does not gloss up next to a bedliner or wear its scratches in the sun.
Key Benefits
- Polymer-reinforced aluminum top panels, 22 percent stronger than the previous MX4 generation.
- Carries 400 lbs of evenly spread load on the closed cover - meaningful on an 8' span.
- Integrated tailgate seal lets the cover close with the tailgate up or dropped.
- Patented auto-latch security system, with revised prop rod clips and lock components on this generation.
- Revised EPDM rubber perimeter seals and tight-fit clamps keep weather out of a long box.
- Folds against the cab for 100 percent bed access with nothing to unbolt or store.
- Click-in bolt-on install in under 30 minutes, no drilling on most applications.
- Five-year limited warranty and built in Missouri, USA.

Fitment
448311 fits 2008-2016 Ford F-250 Super Duty and F-350 Super Duty pickups with the 8' long box (BAK's own dealer listings label the same box 8' 2").
Does not fit the 6'9" short box on the same trucks, and does not carry over to the 1999-2007 body or to the 2017-and-newer Super Duty - Ford changed the body for 2008 and again for 2017, and BAK part numbers change with it. Bed rail caps, cargo management systems, and a tailgate step are not included with this cover.
