The BAK BAKFlip MX4 EZ-Lift is the ultimate hard folding tonneau cover designed for 2019 to 2026 Chevy Silverado and GMC Sierra trucks with a 5-foot 9-inch bed. Constructed with durable aluminum panels and high-density polymer cores, this cover offers exceptional strength and weather resistance, ensuring your cargo stays protected in any climate. Its innovative design features spring/torsion-assisted panels, oversized paddle latch, and Flip Assist system, making opening and folding effortless even while wearing gloves or in low-light conditions. The lightweight yet sturdy construction does not compromise security or durability, providing a secure seal against water intrusion with upgraded perimeter seals and tight-fit clamps.
Operating the MX4 is quick and simple. With a single release of the oversized paddle handle, the cover folds toward the bulkhead, granting full bed access. When folded against the cab, it allows for 100 percent bed access, making it easy to transport oversized items. The cover’s design ensures that the third brake light and OEM camera are fully visible, maintaining safety and visibility at all times. Installation is straightforward, with a click-in design that typically takes less than 30 minutes and requires no drilling for most makes and models, making it ideal for DIY enthusiasts.
Built to withstand the harshest conditions, the MX4 has been tested in temperatures ranging from -40 to 180 degrees Fahrenheit and humidity levels up to 95 percent. It is backed by a 5-year warranty supported by a dedicated team of product experts based in the USA. Whether you need reliable weather protection or easy access to your truck bed, the BAKFlip MX4 EZ-Lift offers a perfect combination of convenience, security, and durability for your pickup truck.
