Description

The BAK Industries BAKFlip MX4 truck bed cover features heavy-duty aluminum top panels and side rails with high-density polymer cores, making it resistant to cuts and slashes and enhancing security. It boasts premium EPDM rubber perimeter seals and a dual-action tailgate seal for superior weather protection, allowing the tailgate to operate independently of the cover's position. The cover folds towards the bulkhead and can be secured upright against the rear window, providing 100% bed access. This GEN 3 model offers a 22% increase in strength and improved lock components for enhanced forced entry resistance compared to the GEN 2. Its sleek, low-profile design sits flush with the truck's bed rails and features a textured matte black finish.
