The BAKFlip MX4 Gen 3 is the latest evolution of RealTruck’s most popular tonneau cover.
The BAK has been redesigned for improved strength, security, and all-weather performance.
Featuring alloy-based construction, the Gen 3 MX4 includes heavy-duty aluminum side rails and top panels, reinforced with high-density polymer cores.
This updated design delivers a 22 percent increase in strength over the previous generation, making it capable of handling daily use, heavy loads, and harsh environments.
Security has been upgraded with BAK’s patented auto-latching system that secures the cover automatically when closed.
Newly engineered lock components provide added resistance to tampering and forced entry, allowing you to transport your gear with confidence.
In rough weather, the Gen 3 MX4 holds strong with revised EPDM perimeter seals and tight-fit clamps that offer the best seal yet, helping prevent water intrusion along the bed rails.
A longer dual-action tailgate seal weatherproofs the tailgate while preserving full functionality, whether the cover is open or closed.
While the MX4 is built tough, it doesn’t compromise on looks with its flush-mount design that gives it a sleek, low-profile appearance.
A textured matte-black finish across all surfaces delivers a clean, subtle aesthetic.
Installation is easier than ever with a new click-in rail system that cuts install time by up to 12 percent.
Day-to-day use is just as simple—drop the tailgate, unlatch, and fold the cover forward.
For complete bed access, fold the cover against the cab without blocking your third brake light.
The BAKFlip MX4 Gen 3 is proudly assembled in Missouri using globally sourced materials and backed by a 5-year warranty.
