The BAK MX4 (GEN 3) is the latest evolution of BAK's best-selling truck bed cover, designed to provide top-tier durability, security, and weather resistance for Nissan Titan owners with a 5' 7" bed. Constructed primarily from high-density polymer-reinforced aluminum panels, this cover offers a 22% increase in strength over previous models, ensuring reliable protection for your cargo. Its sleek, textured matte black finish complements your truck's profile, sitting flush with the bed rails for a seamless, integrated look. The innovative design allows the cover to fold against the cab, granting full access to your truck bed while maintaining a low profile whether open or closed.
Security features have been significantly upgraded with re-engineered lock components that enhance resistance to forced entry, coupled with BAK's patented auto-latching system that automatically secures the cover when closed. This ensures your belongings are well protected, whether you're parked overnight or on the go. Weatherproofing is improved with revised EPDM rubber perimeter seals and tight-fit clamps that prevent water seepage, alongside an extra-long dual-action tailgate seal providing superior weather protection for the tailgate area. These features work together to keep your cargo dry in heavy rain or snow, while the integrated water drainage system efficiently channels moisture away from the bed.
The MX4 (GEN 3) is designed for easy installation with a quick, one-person setup that takes approximately 12% less time compared to previous models thanks to a new click-in design. Its precision-engineered aluminum side rails and frame ensure durability and strength, supporting a weight capacity of up to 400 pounds evenly distributed. The cover includes premium rubber bumpers to protect the cab when folded upright and re-engineered prop rod clips for secure positioning. With compatibility spanning models from 2017 to 2024 Nissan Titans, this cover is a practical, stylish upgrade for truck owners seeking a reliable and sleek tonneau cover that enhances security, weather resistance, and overall truck functionality.
Assembled in Missouri and backed by a 5-year warranty, the BAK MX4 (GEN 3) offers a combination of advanced features, durable construction, and a refined appearance that complements your vehicle's aesthetics while providing reliable bed protection and easy access.
