Whether you’re transporting a load of family furniture or loaded down with luggage, your costly cargo deserves the ultimate in open-road protection – the BAK BAKFlip MX4 Folding Tonneau.

Not to mention, a UV- and scratch-resistant matte black finish for a super sharp look. Perhaps most impressive of all is its maximum weight rating of 400 evenly distributed lbs, so don’t worry about it caving in any time soon.

Up or down, the BAK MX4 Tonneau offers full truck bed access thanks to a handily integrated tailgate seal and is equipped with long-lasting latch housing components. The premium option in MX4’s aluminum series, your BAK BAKFlip Folding Tonneau Cover has a 3-year warranty.

Recently bought this for my truck. Low profile. Matte black. Looks great. Installed by myself. Took a little longer than usual just because I wanted to make sure it was sealed properly to prevent leaking. Drove through down pour rain next day and noticed several leaks. Mainly up near front of bed on sides and somehow small puddle in middle of bed. Also noticed rubber lips that runs up the bed rails was not cut evenly. Not sure if this is what is causing leaking but it is noticeable.

The MX4 looks nice and is good quality. Our truck has the factory spray bed liner so the self stick foam seal is required on the front of the bed. There is no way that this seal will remain in place with the self adhesive as it is on the rough edge of the bed liner.The cover really needs to be and inch longer to create a better water seal. Over all it is a good product. Easy Install.

I decided on the BakFlip after seeing it displayed at the dealer. My wife purchased it for me as a Christmas present. Once I unpacked it and verified all the parts were there it only took about 45 minutes to install. So far the truck bed has stayed dry. THe only issue I had was there were a couple of scuff marks caused I assume in shipping. But overall it is a great cover....
