RealTruck BAKFlip MX4 Hard Folding Tonneau Cover

The world's best-selling truck bed cover just got even better.

Introducing the all-new BAKFlip® MX4 Gen 3—an evolution of RealTruck's most popular tonneau cover. This next-generation upgrade builds on everything truck owners love about the original MX4, now enhanced with improved functionality, greater durability, and elevated security.

The new BAKFlip MX4 is constructed primarily from alloy materials, including heavy-duty aluminum top panels and side rails. Reinforced with high-density polymer cores, each panel delivers a 22-percent increase in overall strength.

Security is also enhanced. In addition to BAK's patented auto-latching system, which automatically secures the cover when closed, the Gen 3 features re-engineered lock components for a 55 percent improvement in resistance to forced entry. No matter the cargo you're transporting, you can rest assured knowing your gear's protected.

When the weather turns, the Gen 3 MX4 holds strong. Revised EPDM rubber perimeter seals and tight-fit clamps provide our best seal yet, preventing seepage between the bed cover and bed rails. At the rear of the cover, a 13-percent longer dual-action tailgate seal weatherproofs the tailgate. This innovative design also improves operation, maintaining factory tailgate functionality regardless of the cover's position.

The BAKFlip MX4 isn't only durable, it's also sleek and stylish. Unlike competitors, the BAKFlip MX4 sits flush with your pickup's bed rails, practically disappearing into your truck's profile. And with a sleek, textured matte-black finish across all surfaces, the MX4 looks great whether open or closed.

Installation is streamlined thanks to an improved click-in mounting system, reducing setup time by 12 percent. Operating the cover is just as simple—drop the tailgate, release the rear latch mechanism, and fold the cover toward the bulkhead. If full bed access is required, fold the cover flush against the rear window—third brake light visibility remains unobstructed in any position.
