Enhanced durability and security for your truck bed with sleek design.

The BAK Industries BAKFlip MX4 Tonneau Cover represents a significant advancement in truck bed protection and functionality. Constructed from high-density polymer-reinforced aluminum, this hard folding cover is designed to be 22 percent stronger than its predecessor, ensuring enhanced durability for all types of cargo. The low-profile design allows the cover to sit flush with the truck bed rails, providing a streamlined appearance that complements the vehicle's aesthetics.

This tonneau cover features a front hinge that allows the entire cover to flip up when folded, granting full access to the truck bed. The precision-engineered aluminum side rails and frame contribute to its robust construction, while the textured matte black finish adds a stylish touch. The BAKFlip MX4 is equipped with an automatic latching system that secures the cover when closed, along with re-engineered lock components that improve resistance to forced entry, ensuring your gear remains protected.

Weather resistance is a key feature of the BAKFlip MX4, with revised EPDM rubber perimeter seals and a longer dual-action tailgate seal that prevent water seepage. Installation is straightforward, requiring no drilling and featuring a new click-in design that reduces installation time by 12 percent. With its combination of strength, security, and sleek design, the BAKFlip MX4 Tonneau Cover is a practical choice for truck owners seeking reliable bed protection.
