America’s best-selling truck bed cover just got even better.Introducing the BAKFlip MX4 Gen 3—the latest evolution of RealTruck’s most popular tonneau cover. Now better than ever, the BAK has redesigned the for improved strength, security, and all-weather performance. The Gen 3 MX4 features alloy-based construction, including 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 even more capable of handling daily use, heavy loads, and harsh environments. Security has also been upgraded. BAK’s patented auto-latching system 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. Revised EPDM perimeter seals and tight-fit clamps 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. The flush-mount design gives it a sleek, low-profile appearance, while 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.
