EZ-Lift does more of the heavy lifting for you with a lightweight feel. Fold it up with one hand using one-third the effort—just 10.5 lbs vs. 30 lbs for heavier covers.
The extra-large paddle handle is easy to find, grab, and operate with one hand. EZ-Lift automatically unlatches as you lift—no extra step required.
A first-of-its-kind paddle handle creates a tighter latch, while the patented auto-latch system locks the moment it closes, eliminating manual cable pulls.
Advanced seals and precision-fit clamps create a tight, edge-to-edge barrier to block out the elements and keep your cargo dry.
Premium-grade, multi-layer aluminum construction over a high-density core delivers stronger, more durable performance that lasts for years.
Simply fold to the cab, secure, and safely drive with the cover fully open. No removal needed for oversized cargo.
America's best-selling truck bed cover just got easier to use—for everyone.
The RealTruck® BAKFlip® MX4 EZ-Lift Hard Folding Truck Bed Cover builds on everything truck owners already love about the MX4—now with an EZ-Lift system that does more of the heavy lifting for you. Fold the cover open with one hand using just one-third the effort of heavier covers—10.5 lbs. of lift force versus nearly 30 lbs.
Premium-grade, multi-layer aluminum construction over a high-density core delivers a stronger, more durable surface tested for years of reliable performance. Single-layer construction bends under pressure—the MX4 EZ-Lift doesn't. A sleek, textured matte black finish across all surfaces keeps the profile clean whether the cover is open or closed.
The extra-large paddle handle is easy to find, grab, and operate with one hand. EZ-Lift automatically unlatches as you lift—no extra step required. The patented auto-latch system locks the moment the cover closes, and self-unlatching middle panels eliminate manual cable pulls entirely, making this the most secure MX4 ever with fewer steps than before. The first-of-its-kind paddle handle also creates a tighter latch for added peace of mind.
Advanced seals and precision-fit clamps create a tight, edge-to-edge barrier to block out the elements and keep cargo dry in any conditions. When you need full bed access, simply fold the cover to the cab, secure it, and drive—no removal needed for large cargo. The MX4 EZ-Lift is also the industry's only hard-fold cover that doesn't block your third brake light in any position.
Installation is a straightforward bolt-on process using the included clamps and takes 30 minutes or less—no drilling required. The RealTruck BAKFlip MX4 EZ-Lift is proudly assembled in the USA and backed by a 5-year warranty.
