The BAK Flip MX4 (GEN 3) by BAK is a highly durable and stylish hard folding truck bed cover designed specifically for 2021 and 2022 Ford F-150 models with a 5' 7" bed, including the 2022 Lightning. Constructed primarily from high-density polymer-reinforced aluminum, this cover offers a 22 percent increase in strength over previous models, ensuring reliable protection for your cargo. Its sleek, textured matte black finish seamlessly integrates with your truck's profile, providing an aesthetic upgrade while maintaining a low-profile appearance. The MX4 (GEN 3) features precision-engineered aluminum side rails and frame for added robustness, and sits flush with your truck's bed rails for a clean, integrated look.
The cover's innovative design allows it to fold flat against the cab, granting full bed access when needed, with a simple, one-person installation process that takes approximately 12 percent less time thanks to the all-new click-in mechanism. Enhanced weather sealing is achieved through re-engineered perimeter seals and tight-fit clamps, which prevent water seepage and protect your cargo from the elements. An extended dual-action tailgate seal further improves weather resistance, ensuring your truck bed remains dry under various conditions.
Security is a key feature of the BAK Flip MX4 (GEN 3). It utilizes BAK's patented auto-latching system that automatically secures the cover when closed, along with re-engineered lock components that provide increased resistance against forced entry. This combination offers peace of mind that your gear is well protected. Additional features include rubber bumpers to prevent cab damage when the cover is folded upright, integrated water drainage, and a 400-pound weight capacity for versatile cargo management. The cover is designed for easy installation and maintenance, with re-engineered prop rod clips ensuring a secure hold. Backed by a 5-year warranty, the BAK Flip MX4 (GEN 3) is the ultimate combination of strength, security, and style for your Ford F-150.
