When you need to haul gear that’s taller or longer than the bed, you don’t have to remove this cover. The tri-fold design lets you flip it open for partial or full access in seconds. Built-in prop rods hold the panels upright so you can drive with the bed completely open. When closed, the low-profile fit stays inside the bed rails for a clean look that still works with stake-pocket-mounted accessories.
Locking down your cargo is simple. Each panel automatically latches when closed, creating a secure truck bed as soon as you shut and lock the tailgate. The integrated buckle system lets you secure the cover folded, flipped up, or fully closed, and the rear seal design means you can open or close the tailgate whether the cover is up or down.
Rain, dust, and sun are no match for the MX4. Matte black rubber seals and a built-in drainage system help route water away from the bed, keeping your gear dry. The 1/2" thick aluminum panels are rustproof and capped with a matte black finish that resists UV rays, scratches, and scuffs, so it stays looking sharp through every season.
This cover is built for strength without adding unnecessary weight. Aircraft-grade aluminum rails and premium-density foam-core panels deliver a solid structure that supports up to 400 lbs of evenly distributed weight. The rustproof materials and black powder-coat finish keep everything rigid and corrosion-free for long-term use.
Getting it installed doesn’t require special tools or drilling. The frame rails clamp to the inside of the bed rails, and the front hinge rail bolts securely to the frame rails. The result is a tight, professional-looking fit that’s ready to go right away and stays aligned even after years of use.

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.

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!
