RealTruck, a major player in the aftermarket truck accessory market, has announced the release of the BAKFlip MX4 (Gen 3) tonneau cover. This latest iteration of the popular MX4 builds upon the features of its predecessor with improvements to strength, security, and weather protection, according to RealTruck.

The BAKFlip MX4 (Gen 3) is a hard-folding tonneau cover designed to provide truck bed security and weather resistance while maintaining convenient access to the truck bed. RealTruck states that the MX4 (Gen 3) is constructed from heavy-duty aluminum top panels and side rails, reinforced with high-density polymer cores. According to RealTruck, this construction results in a 22 percent increase in overall strength compared to the previous MX4 model. This added strength should improve the cover's ability to withstand impacts and heavy loads, with a reported weight capacity of 400 lbs (evenly distributed).

Security has also been a focus in the Gen 3 redesign. In addition to BAK's existing auto-latching system, RealTruck states that the MX4 (Gen 3) features re-engineered lock components designed for improved resistance to forced entry. This upgrade aims to provide truck owners with greater peace of mind when storing valuable cargo in the truck bed.

Weather protection is another key area of improvement. According to RealTruck, the BAKFlip MX4 (Gen 3) incorporates revised EPDM rubber perimeter seals and tight-fit clamps to prevent water intrusion. The rear of the cover features a 13 percent longer dual-action tailgate seal for enhanced weather protection at the tailgate. RealTruck notes that this design maintains factory tailgate functionality regardless of the cover's position.

Aesthetically, the BAKFlip MX4 (Gen 3) maintains a sleek, low-profile design, sitting flush with the truck bed rails. RealTruck states that the cover features a textured matte black finish across all surfaces for a consistent look whether open or closed.

Installation has been streamlined with an improved click-in mounting system, which RealTruck claims reduces setup time by 12 percent. The cover can be operated by releasing the rear latch mechanism and folding the cover towards the cab. For full bed access, the cover can be folded flush against the rear window, maintaining third brake light visibility.
