With some covers you have to pull the whole thing off just to haul taller items. The BAKFlip MX4 makes that unnecessary. Its tri-fold aluminum panels flip open in sections, letting you access part or all of your bed in seconds. When you need full space, the prop rods hold it securely upright so you can drive with the bed completely open. The integrated buckle system locks the panels in the folded, flipped up, or closed position, so it stays put on the road.
Keeping gear safe is simple with the MX4. The panels latch automatically as they close, creating a secure enclosure when your tailgate is shut and locked. The rear seal design even lets you open or close the tailgate whether the cover is open or down, so you don’t have to choose between convenience and security.
Rain, sun, or snow — this cover is ready for it. The matte black rubber seals and built-in drainage system help keep water out of the bed, while the 1/2" thick rustproof aluminum panels are resistant to scratches, scuffs, and UV rays. The premium density foam core adds strength without adding weight, and the rustproof aluminum rails with a black powder coat finish keep everything solid and corrosion-free.
The MX4 sits flush inside the bed rails for a clean, low-profile appearance. Because it mounts inside the rails, you can still use stake-pocket-mounted accessories or raised side rails without interference. It installs easily with no drilling — just clamp it on and bolt the front hinge rail to the frame rails using the included hardware.
This cover isn’t just for looks. It’s rated to hold up to 400 lbs of evenly distributed weight, so it can handle extra gear or light loads on top when needed. The durable aluminum panels and aircraft-grade rails give it the strength to last through years of hauling and weather.

Katie Osborne: Katie Osborne with trucks hero here to tell you what makes this Backflip MX for the number one selling hard truck bed cover on the market. The aluminum encased panels provide security and weather protection when closed. And when folded open, it provides full bed access, plus you can then drive it around town by securing it with a prop rod. And of course, this low profile matte black finish looks great on any truck.

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.

You mentioned that the glue holding the pads are failing. I wanted to see if you would be able to send a picture to show the locations.

The cover is still excellent and keeps our items dry and secure on those road trips. I stand by my initial review and still wish the weatherstripping would stick the the spray in liner better but its only been a minor annoyance that hasnt resulted in any water getting into the bed.

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!
