BAK 20-26 GM Silverado/Sierra 2500/3500 HD 8.2ft Bed BAKFlip MX4 TS - 449134TS

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. 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.

Upgraded rubber seals, tight-fit clamps, and a dual-action tailgate seal keep rain and debris out, with any moisture funneled away through integrated water channels and drainage tubes (in most applications). BAK's redesigned auto-latching system secures your bed with each panel fold, while the T-slot rails provide versatile mounting for crossbars, baskets, rooftop tents, and more. Installation is fast thanks to click-in clamps, reducing install time by 12 percent.
