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.

Manufactured from heavy-duty aluminum panels – with panel skins 1.5x thicker than the BAKFlip G2 – and enhanced with a dense foam core, this tri-fold tonneau cover combines functionality with durability. 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.

I decided to finally install a tonneau cover on my 14' Ram HD and I wanted something durable and easier to open open up and close. Another selling feature was with my lockable tailgate I can lock up the contents of my bed. Install was very straight forward, I have a bed liner so there was some slight trimming to get side rails to fit perfectly. Cover came shipped with a broken clip but AutoAnything sent out a replacement right away. Love the product thus far

Just what I was looking for...

The MX4 is exactly what I expected and looks great. Though I've only had it for two months, I'm very satisfied. I installed it myself which was a bit of a challenge, but the instructions were clear and materials well marked. I've found that some water gets into the bed, but not enough to create problems. I'd recommend it for anyone looking for a sleek and functional tonneau cover.

Final evaluation still out.

Since my truck bed had liner on top of side I did not use rubber strip; it leaked. I took it off and had a hard time attaching rail with rubber strip since there was not enough room. I did work it in with a lot of effort. Waiting for a rain to see if it leaks. To lift middle panel, I have to release from both sides of the panel.

MX4 best tonneau for the F150

Super easy to install. Takes a few min to get it square but if you take your time to make it perfect its worth it. Seems durable and well made, smudges a little but a little 303 protectant on it will keep it nice and matte. Great service by Autoanything, couldnt be better.
