Hauling big cargo doesn’t mean you have to lose protection for your bed. The BAKFlip MX4 folds in three sections so you can open just part of it or flip the whole thing up for full access in seconds. Prop rods hold the panels upright so you can drive with the bed completely open. The integrated buckle system lets you secure the cover in folded, flipped-up, or closed positions, keeping it stable on the road and easy to adjust for whatever you’re hauling.
Rain, snow, and wash water stay out thanks to the matte black rubber seals and a built-in drainage system that channels water away from the bed. The rear seal lets you open and close the tailgate whether the cover is up or down, so you don’t have to fight with it every time you load up. The fit is tight and reliable, keeping gear dry through rough weather while giving the bed a clean, finished look.
Each panel is built from 1/2" thick, rustproof aluminum with a premium-density foam core for added stiffness. The cover is rated to hold up to 400 lbs of evenly distributed weight, so you can load extra gear on top when needed. The matte black finish resists scratches, scuffs, and UV rays, so it stays looking sharp even after years of use in the sun or snow.
The MX4 sits flush inside the bed rails for a low-profile look that doesn’t hide your truck’s shape. Mounting inside the rails also keeps stake pockets open so you can use racks or tie-downs without removing the cover. Aircraft-grade aluminum rails with a black powder coat finish form a strong, rustproof base, and the easy, no-drill clamp system keeps installation simple and precise.
If you run a ladder rack or other rail-mounted gear, the MX4 plays well with them. Because it mounts inside the rails and opens at the tailgate, it’s compatible with rack systems designed for tonneau covers. Whether you’re hauling ladders, kayaks, or overland gear, the cover keeps everything below secure while leaving room above for more cargo.

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.

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.
