The BAK BAKFlip MX4 (GEN 3) is the latest evolution of the best-selling truck bed cover, engineered for durability, security, and weather resistance. Designed specifically for 2020 Chevy Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD models with a 6' 10" bed, this tonneau cover offers a sleek, flush-mounted profile that seamlessly integrates with your truck's bed rails. The textured matte black finish not only enhances the aesthetic appeal but also provides a durable surface resistant to scratches and UV damage. Constructed primarily from high-density polymer-reinforced aluminum, the top panels are 22% stronger than the previous model, ensuring long-lasting strength and reliability. The precision-engineered side rails and frame contribute to the overall rigidity, while the innovative design allows the cover to fold in half, providing full access to the bed or a secure, closed position for transport. The BAKFlip MX4 (GEN 3) features re-engineered auto-latching panels for improved security, with lock components designed to resist forced entry, giving you peace of mind regardless of what you carry. Enhanced perimeter seals and tight-fit clamps deliver superior weatherproofing, preventing water seepage and protecting cargo from the elements. The rear dual-action tailgate seal is 13% longer, offering additional weather protection while maintaining full tailgate functionality. Installation is straightforward, with a 12% quicker setup thanks to the all-new click-in design that allows for a one-person setup process. The cover supports up to 400 pounds of evenly distributed weight, making it suitable for various hauling needs. Additional features include integrated water drainage systems, protective rubber bumpers for the cab, and re-engineered prop rod clips for secure handling. This cover also offers comprehensive third brake light visibility in all positions and is assembled in Missouri, backed by a 5-year warranty. Whether you need to secure tools, equipment, or cargo, the BAKFlip MX4 (GEN 3) provides the durability, security, and weather resistance required for demanding conditions, all while maintaining a sleek appearance that complements your truck's profile.
