BAKFlip MX4 TS Hard Folding Tonneau Cover
BAKFlip MX4 TS vs. Standard BAKFlip MX4
The BAKFlip MX4 TS and standard BAKFlip MX4 share many of the same features, including aluminum construction, automatic latching, full bed access, a 400-lb. weight capacity, low-profile styling, and a 5-year warranty.
The main difference is the rail system.
The standard MX4 uses conventional rails, while the MX4 TS adds integrated T-slot channels for compatible racks, crossbars, carriers, and cargo accessories.
If you do not plan to use a rack system, the standard MX4 may be all you need. If you want more cargo flexibility above the bed, the MX4 TS is the more versatile option.
