If you drive a 2024-2026 Toyota Tacoma with a 5' bed, the BAKFlip MX4 TS (Gen 3) Hard Folding Tonneau Cover with T-Slot Rails 449446TS is a cover to look at. The hard panels protect your cargo from weather and prying eyes, and the folding design opens the bed in one move.
This is the rack-ready MX4: the Gen 3 folding cover with T-slot rails built into the side rails.
A Tacoma bed is built for gear. Covering it keeps that gear locked up and out of the weather without giving up access when you need it.
Tougher than the original. BAK rebuilt the MX4 panels in layered aluminum with a high-density polymer core, a 22% strength increase over the first-generation cover. Aluminum rails and a stiff frame support up to 400 lb of evenly distributed cargo on top.
Auto-latch security. The patented auto-latch engages the moment you close the cover, so there is no separate locking step to forget. Re-engineered latching panels and lock components improve forced-entry resistance compared with the previous generation.
Rack-ready from day one. T-slot channels in the side rails take racks, cargo holders, tents and cross bars, all sold separately. You get a hard folding cover and a place to carry gear above it.
Textured matte black, Multi-Shield coated. The coating is built to resist scratches, scuffs, dents and UV, and the cover stays nearly flush with the bed rails.
Full bed access without taking the cover off the truck. Fold it toward the bulkhead, let the prop rod clips hold it open, and load tall or bulky cargo. The bumpers keep the cab protected, and the third brake light stays visible whether the cover is open or closed.
Sealed against the weather. Revised EPDM rubber perimeter seals and tight-fit clamps close the gap between the cover and the bed rails, and the dual-action tailgate seal, available on most applications, is 13% longer than before. An integrated drainage system carries water away.
Fit notes: It requires the Toyota Deck Rail System; it is not compatible with Trail Special Edition storage boxes. Also match the bed length shown in the fitment line above.
For a folding cover that locks itself, seals tight and fits flush, the BAK 449446TS is a strong choice. It is assembled in the USA, backed by a five-year limited warranty, and available from Track Ready Products.
Bolt-on, click-in mounting keeps the install simple: one person, basic hand tools, usually 30 minutes or less, and the hardware is in the box.
Start with a clean set of rails. Position the cover, tighten the clamps evenly, and run it through a full open and close cycle to check that it moves freely and latches.
Recheck the clamps after about a week, wash with mild automotive soap and water, and clear off snow and ice before opening. Keep the cover secured at all points whenever you drive.
