The BAK BAKFlip MX4 (GEN 3) is the latest evolution of the world's best-selling truck bed cover, designed specifically for Ford Super Duty trucks with a 6' 9" bed from model years 2011 to 2016. Crafted with precision engineering, this hard folding tonneau cover features high-density polymer-reinforced aluminum top panels, providing a 22 percent increase in strength over older models. These durable panels are lightweight yet incredibly resilient, ensuring your cargo remains protected under all conditions. The cover's sleek matte black finish offers a modern, stylish look that complements your truck's profile while resisting scratches and weathering.
Enhanced security is a key feature of the MX4 (GEN 3). The auto-latching system automatically secures the cover when closed, and re-engineered lock components bolster resistance against forced entry. The design includes improved perimeter seals and tight-fit clamps that deliver superior weather resistance, preventing water seepage and protecting your valuables from the elements. The extended dual-action tailgate seal provides additional weatherproofing for the tailgate area, maintaining functionality without sacrificing protection. The cover folds into a low-profile position, allowing full bed access when needed, and sits flush with your truck's rails for a seamless appearance.
Installation is simplified with a new click-in design that reduces setup time by approximately 12 percent, allowing for quick and easy setup by a single person. The precision-engineered aluminum side rails and frame provide robust support, with a weight capacity of 400 pounds distributed evenly across the surface. Additional features include integrated water drainage, rubber bumpers that protect the cab during folding, and re-engineered prop rod clips for secure positioning. Whether open or closed, the MX4 maintains a sleek, textured look, while the comprehensive 5-year warranty offers peace of mind. Built in Missouri, this tonneau cover combines durability, security, and style for a premium truck bed solution.
