Description

The BAKFlip MX4 (GEN 3) Hard Folding Truck Bed Cover features high-density polymer-reinforced aluminum top panels that are 22% stronger than the original MX4. It has a textured matte black finish across all components and folds against the cab for 100% bed access. The cover includes re-engineered automatic latching panels for improved security and a comprehensive 3rd brake light visibility in all positions. It is designed for simple one-person installation and includes re-engineered perimeter seals, tight-fit clamps, and an extra-long, dual-action tailgate seal for superior weather protection.
