The BAK BAKFlip MX4 (GEN 3) is a premium hard folding tonneau cover designed specifically for Ford Super Duty trucks from 2017 to 2026 with an 8-foot bed. Constructed primarily from high-density polymer-reinforced aluminum, the top panels are 22 percent stronger than previous models, providing enhanced durability and resistance to harsh weather conditions. Its sleek, textured matte black finish offers a modern look that seamlessly complements your truck's profile while sitting flush with the bed rails for a low-profile, integrated appearance.
Featuring re-engineered auto-latching panels, the MX4 (GEN 3) improves security by offering more resistant lock components to prevent forced entry. The revised perimeter seals and tight-fit clamps deliver superior weatherproofing by preventing seepage, even during heavy rain or snow. Additionally, a longer dual-action tailgate seal provides extra protection at the rear, maintaining full tailgate functionality regardless of the cover's position. The innovative design ensures quick, tool-free installation, taking approximately 12 percent less time thanks to the new click-in system, making it accessible for one-person setup.
The MX4 is built to support up to 400 pounds evenly distributed, making it suitable for a variety of cargo. Its integrated water drainage system helps manage moisture, ensuring your belongings stay dry. When not in use, the cover folds against the cab, granting full access to the truck bed. Premium features include rubber bumpers that protect the cab when folded, re-engineered prop rod clips for secure hold, and comprehensive third brake light visibility in all positions. With its durable construction, stylish finish, and thoughtful engineering, the BAKFlip MX4 (GEN 3) offers a reliable, weather-resistant solution that enhances your truck's functionality and appearance.
Assembled in Missouri and backed by a 5-year warranty, this tonneau cover is a perfect upgrade for serious truck owners seeking durability, security, and style in a bed cover.
