BAK 14-19 GMC/Chevrolet Silverado/Sierra 5ft 9in Bed BAKFlip MX4 EZ-Lift - 450120

The world’s best-selling tonneau cover just got even better. Introducing the all-new RealTruck® MX4—an evolution of the ever-popular [MX4](https://realtruck.com/p/bakflip-mx4-tonneau-cover/), now featuring Easy Open and Easy Fold technology. With the MX4, RealTruck’s mission is to optimize operation with assisted opening, unlatching, and folding. Innovative mechanisms, such as RealTruck’s spring/torsion-assisted panels, oversized paddle latch, and exclusive Flip Assist system, deliver a lightweight feel for effortless one-handed cargo access—even when loading in the dark or while wearing gloves. However, don’t confuse the MX4’s lightweight feel with a reduction in quality. The newest addition to the MX4 family retains the durability and exceptional build quality of its siblings, including ultra-strong aluminum panels with high-density polymer cores. This durable construction, paired with RealTruck’s extra-large paddle handle and auto-latch locking system, delivers our tightest-closing, most secure MX4 to date. Even water doesn’t stand a chance with the integrated perimeter seals and new tight-fit clamps. Operating the cover is quick and easy—with a quick release of the oversized paddle handle, the cover easily folds toward the bulkhead. Gain 100 percent bed access by folding all the way against the cab, enabling you to transport oversized cargo with ease. The MX4’s innovative design doesn’t block the third brake light or integrated camera, retaining complete visibility in any position. DIY installation is just as simple with RealTruck’s innovative click-in design. No need for an extra hand to help, and no drilling for most makes and models for hassle-free mounting in under 30 minutes. Tested in the harshest conditions and guaranteed by a 5-year warranty, the MX4 offers unmatched performance in any climate.
