Part 448330 brings BAK's BAKFlip MX4 design to the 2017-2025 Ford F-250 and F-350 with a 6'9" bed. The hard panels protect your cargo from weather and prying eyes, and the folding design opens the bed in one move.
The BAKFlip MX4 is BAK's step-up folding cover. This Gen 3 version adds stronger panels, a tighter seal and a re-engineered auto-latch.
On a Super Duty the bed is a rolling toolbox, and a hard cover keeps what is in it protected from weather and out of sight.
A low, tidy profile. Textured matte black on every component and a flush fit with the rails make the cover look like it belongs on the truck.
It locks itself. Close the cover and the latch engages. Gen 3 uses redesigned latching panels and lock hardware that BAK built to resist forced entry better than the Gen 2 design.
More for rain and road spray to get past. Updated EPDM perimeter seals, tight-fit clamps, a longer dual-action tailgate seal on most applications and an integrated drainage system all work to keep the bed dry.
Tougher than the original. BAK rebuilt the MX4 panels in layered aluminum with a high-density polymer core, a 22% strength increase over the first-generation cover. Aluminum rails and a stiff frame support up to 400 lb of evenly distributed cargo on top.
Full bed access without taking the cover off the truck. Fold it toward the bulkhead, let the prop rod clips hold it open, and load tall or bulky cargo. The bumpers keep the cab protected, and the third brake light stays visible whether the cover is open or closed.
Assembled in the USA and covered by a five-year limited warranty, the BAK 448330 is the Gen 3 upgrade for owners who want a stronger, tighter-sealing folding cover. Order it from Track Ready Products and check the bed length above.
Installation is a one-person, bolt-on job with a click-in design that is 12% quicker than the previous generation. Most trucks need no drilling or trimming.
Wipe down the rails, seat the cover, then snug the clamps a little at a time on both sides so it pulls down square. Test the latch and the open and close action while the bed is still empty.
Recheck the clamps after about a week, wash with mild automotive soap and water, and clear off snow and ice before opening. Keep the cover secured at all points whenever you drive.
