The BAK BAKFlip MX4 (GEN 3) from BAK is the ultimate solution for truck owners seeking durability, security, and style in a tonneau cover. Designed specifically for 2019-2026 Chevy Silverado and GMC Sierra 1500 models with an 8-foot bed, this hard folding cover offers a sleek matte finish that complements your truck's profile. Its innovative design ensures seamless integration with your vehicle, providing a low-profile appearance that practically disappears when folded back, allowing full bed access.
Constructed primarily from high-density polymer-reinforced aluminum top panels and side rails, the MX4 (GEN 3) boasts a 22 percent increase in strength over previous models. This upgraded strength enhances durability against harsh weather conditions and heavy cargo loads. The cover’s advanced sealing system, including re-engineered perimeter seals and tight-fit clamps, ensures superior weather resistance by preventing water seepage, while the extended dual-action tailgate seal offers additional protection for your tailgate area.
Security is a key feature of the MX4 (GEN 3). It incorporates BAK’s patented auto-latching system that automatically secures the cover when closed and features re-engineered lock components for improved resistance against forced entry. Ease of installation is another benefit, with a simplified, quicker setup process that can be accomplished by a single person, thanks to its innovative click-in design. This model also features a comprehensive water drainage system, ensuring that any moisture escapes efficiently, maintaining the integrity of your cargo.
The MX4 (GEN 3) is designed with convenience and style in mind. It includes premium rubber bumpers to protect your cab when the cover is folded upright and re-engineered prop rod clips for secure hold during operation. The textured black finish provides a sleek, professional look that resists scratches and weathering. Capable of supporting up to 400 pounds evenly distributed, this cover is built to handle your toughest jobs while maintaining a low profile. Each unit is assembled in Missouri and comes with a five-year warranty, offering peace of mind along with premium performance.
