RealTruck BAKFlip MX4 TS (GEN 3) Hard Folding Tonneau Cover w/ T-Slot Rails
Description
The best-selling truck bed cover in the world now with built-in rack compatibility.
Introducing the all-new BAKFlip® MX4 TS, available exclusively from RealTruck. This premium tonneau builds on everything enthusiasts love about the BAKFlip MX4—now with built-in rack compatibility via intuitive, built-in T-slot side rails, allowing fast, secure mounting of racks, carriers, tents, and other cargo accessories (sold separately).
As you’d expect from BAK® Industries, the BAKFlip MX4 TS delivers premium quality and performance. Its all-aluminum construction features redesigned top panels with high-density polymer cores, offering a 22 percent increase in strength over the original MX4.
Despite its strength, the BAKFlip MX4 TS maintains an ultra-low profile, sitting nearly flush with your truck’s bed rails for a clean, streamlined appearance. The aluminum alloy is corrosion-resistant and protected by BAK’s proprietary Multi-Shield™ matte black finish, delivering 11x more surface durability and supporting up to 400 pounds of evenly distributed weight on top.
When it comes to weather protection, the BAKFlip MX4 TS is built to perform. Upgraded rubber seals, tight-fit clamps, and a dual-action tailgate seal keep rain and debris out—allowing you to open or close the tailgate in any position. And if any moisture does sneak in, it’s funneled away through integrated water channels and drainage tubes (in most applications).
The BAKFlip MX4 TS doesn’t just lock out the elements—it locks down your cargo, too. BAK’s redesigned auto-latching system secures your bed with each panel fold. Simultaneously, the T-slot rails provide versatile mounting for crossbars, baskets, rooftop tents, and more—maximizing cargo capacity above and below the bed cover.
Operating the cover is simple—drop the tailgate, release the easy-to-use rear latches, and fold the cover forward. For complete bed access, fold it upright against the cab and secure it with heavy-duty prop rods—rubber bumpers prevent scuffs while in the open position. Installation is fast and hassle-free thanks to click-in clamps, reducing install time by 12 percent compared to the previous model.
BAK® is a RealTruck® brand. Each BAKFlip MX4 TS is proudly engineered and assembled in Missouri using globally sourced materials and backed by a 5-year warranty.
