MX4 Hard Folding Tonneau Cover for 21-24 F-150 w/ 5'7" Bed

Part Number: 448339

Sleek, secure, and durable—what else could you want out of a premium hard-folding truck bed cover? The BAKFlip MX4 is constructed entirely from alloy materials, including heavy-duty aluminum top panels and side rails. Unlike soft-folding tonneau covers, the MX4's robust aluminum construction resists cuts and slashes, preventing thieves from damaging the bed cover or accessing your valuables. Unlike competitors, the BAKFlip MX4 sits flush with your pickup's bed rails, practically disappearing into your truck's profile. And with a sleek, textured matte-black finish across all surfaces, the MX4 looks great whether open or closed.

• Full Bed Access. Cover folds toward the cab for 100% bed access with premium rubberseals for exceptional all-weather protection.


• Upgraded Side Rails. Improved rail and clamp design ensures easier-than-ever installation and superior fitment while also increasing panel strength with the ability to withstand up to 400 lbs. of evenly distributed weight.


• Upgraded Side Rails. Improved rail and clamp design ensures easier-than-ever installation and superior fitment while also increasing panel strength with the ability to withstand up to 400 lbs. of evenly distributed weight.


• No Drill Clamp. Improved A-panel retainer clamp assembly reduces potential for dimpling when installing, improves the strength of the panel and boasts an uninterrupted design.


• Easy Operation. The newly refined latch system features a crimp-free design that reduces cable fatigue for added durability and a longer service life.

The BAKFlip MX4 also employs BAK's patented auto-latching side rails, which automatically lock the MX4's panels to prevent thieves from prying at the cover's sides for entry into the bed. No matter the cargo you're transporting, you can rest assured knowing your gear's backed by the premium protection of a BAK truck bed cover. If inclement weather is a concern, don't worry. The BAKFlip MX4 is just as adept at resisting moisture as it is at resisting thieves. Premium EPDM rubber perimeter seals prevent seepage between the bed cover and bed rails, while a dual-action tailgate seal weatherproofs the tailgate. This innovative design also improves operation, allowing you to open and close the tailgate regardless of the cover's position.

Installing the BAKFlip MX4 is quick and easy using the included clamp system and instructions. Operating the cover is just as simple—drop the tailgate, release the rear latch mechanism, and fold the cover toward the bulkhead. If full bed access is required, fold the cover flush against the rear window and support it with the integrated prop rods and re-engineered clips.
