A lot of hard covers make you choose between protection and space, but the BAKFlip MX4 gives you both. Its quad-fold panels flip open in sections so you can access part of the bed or fold it all the way up for full use when hauling lumber, ATVs, or camping gear. Prop rods hold the cover upright so you can drive with the bed completely open. The panels are 1/2" thick aluminum, strong yet light, and the cover itself weighs about 71 lbs for easy handling.
Keeping gear dry and secure is easy with this setup. The MX4 uses automatically latching panels that lock when the tailgate is closed, forming a solid barrier against theft or shifting cargo. Matte black rubber seals and a built-in drainage system channel water away from the bed, while a rear seal lets you open or close the tailgate whether the cover is up or down. It’s not just about looks—it’s functional weather control that works through storms and car washes alike.
You can load up on top without worry. The rustproof, aircraft-grade aluminum panels are rated to hold up to 400 lbs of evenly distributed weight. A premium-density foam core adds strength without extra bulk, and the matte black finish resists scratches, scuffs, and UV rays so it stays clean and sharp after years in the sun.
Mounted inside the bed rails, the MX4 keeps its profile flush with the truck body for a sleek appearance while leaving stake pockets open for racks or tie-downs. The aircraft-grade rails clamp to the inside of your bed—no drilling required—and are finished in black powder coat for long-term durability. It’s also compatible with accessories like the BAKBox2 toolbox if you want to add secure storage under the cover.

Thanks for the great feedback! We're glad you're enjoying the tonneau cover and that being able to use almost the entire truck bed when it's open has been such a big plus. It's also nice knowing your gear stays secure when you lock the tailgate. We appreciate you mentioning the clamps too—that kind of feedback is always helpful. Thanks again, and we hope you keep enjoying your new cover!

The BAKFlip after 2 years is still functioning great. I fixed the curling cushion by applying some strong adhesive to the spots that had detached, taped it in place and let cure for a couple of days. That solved that issue. Would continue to recommend the BAKFlip to others.

I reached out to the manufacturer and they said if you install the rails with the tailgate closed then the rails would sit on top of the tailgate, which is correct.
