Some hard covers make you choose between security and full use of your truck bed. The BAKFlip MX4 solves that with its tri-fold aluminum design. You can flip it forward in sections for partial access or fold it all the way up against the cab and lock it upright with prop rods to drive with the bed completely open. The integrated buckle system keeps everything secure in whatever position you choose.
Rain, snow, and road grime are no match for the MX4’s sealed design. Each ½"-thick rustproof aluminum panel is reinforced with a premium-density foam core for strength up to 400 lbs of evenly distributed weight. Matte black rubber seals and a built-in drainage system channel water away from the bed to help keep your gear dry. The rails clamp inside the bed for a tight, flush fit that works with stake-pocket accessories and side rails.
The MX4 sits inside the bed rails for a flush profile that keeps your truck looking sharp instead of bulky. Its matte black finish resists scratches, scuffs, and UV rays so it holds its color and texture through years of use. Even after countless trips or weather changes, it stays sleek and solid without fading or peeling.
You don’t need extra locks or keys to protect your cargo. The MX4’s panels automatically latch when closed, and once your tailgate is locked, the cover can’t be opened from the outside. That gives you a fully sealed, secure bed for tools, groceries, or weekend gear—all without adding complicated mechanisms.
Getting this cover on is straightforward. The aircraft-grade, powder-coated aluminum frame rails clamp directly to the inside of your bed rails—no drilling required—and bolts secure the front hinge rail in place. It’s ready to use in short order, giving you a sturdy, weather-resistant cover that works hard right away.

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.

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!
