BAK Industries BAKFlip MX4 TS 449409TS is a hard folding matte-black tonneau cover for the 2007-2021 Toyota Tundra with the 5' 7" (66.7 in) bed, built for trucks that do NOT have the factory deck rail system. The TS suffix is the whole point of this part number: the side rails carry integrated T-slot channels, so the cover brings its own accessory mounting track to a bed that never had one.

That is a different proposition from a plain MX4. On a Tundra without Toyota's rail system, a standard cover just seals the box; the TS rails give you a slotted channel down each side to hang gear from. Underneath it is still full MX4: high-density polymer-reinforced aluminum top panels on aluminum side rails, textured matte black end to end, with tight-fit clamps holding the assembly to the bed.

Key Benefits

Integrated T-slot rails add an accessory mounting channel to a Tundra bed that has no factory track system.
Polymer-reinforced aluminum panels rated for 400 lbs of evenly distributed weight.
Folds flush against the cab for 100 percent bed access, without blocking the third brake light.
Textured matte black across every component, panels and rails alike.
Bolt-on, click-in installation in under 30 minutes with no drilling.
Tight-fit clamps and all fasteners come in the box.
Five-year limited warranty from BAK.

Fitment

449409TS fits the 2007-2021 Toyota Tundra with the 5' 7" (66.7 in) short bed, on trucks without the factory deck rail system.

Does not fit a Tundra with the factory deck rail / track system - RealTruck states the cover is not compatible with deck rail systems, and BAK catalogues 448409T for track-equipped beds. It also will not fit Trail Special Edition bed storage boxes. For the 2022-and-newer Tundra, the equivalent T-slot cover is 449440TS, not this part number.

FAQ

What does the TS in BAKFlip MX4 TS mean?

TS stands for T-Slot rails. The cover's side rails include integrated T-slot channels for mounting accessories, which is why it is specified for Tundras without the factory track system.

Will 449409TS fit a Tundra with the factory deck rail system?

No. RealTruck lists this cover as not compatible with deck rail systems; BAK catalogues 448409T for Tundra beds that have the track system.

Does 449409TS work with a Trail Special Edition Tundra?

No. The cover will not work with Trail Special Edition bed storage boxes.

How much weight can the BAKFlip MX4 TS hold?

400 lbs, evenly distributed across the closed cover.
