The BAKFlip MX4 Tonneau Cover stands out as a premium hard-folding cover designed for ultimate aesthetics, weather resistance, and security.

Crafted entirely from alloy materials, including heavy-duty aluminum top panels and side rails, the MX4 ensures unparalleled durability. Unlike soft-folding tonneau covers, it offers exceptional resistance to penetration, providing top-notch protection for your cargo.

In addition to its durability, the MX4 has a sleek and stylish design. Unlike its competitors, this cover sits flush with your pickup's bed rails, seamlessly blending into your truck's profile. Finished with a sleek matte black coating on all surfaces, the MX4 exudes sophistication whether open or closed.

Concerned about bed access? No need to worry! The MX4 can be easily flipped towards your truck's bulkhead, supported by integrated prop rods, allowing you full access to the cargo area whenever necessary.

Whether you prioritize security, aesthetics, durability, or all three, the BAKFlip MX4 Tonneau Cover is sure to exceed your expectations.
