Features
- Locks the moment it closes: BAK's patented auto-latch engages as each panel closes, so there is no separate locking step. BAK says the Gen 3 lock parts were re-engineered to resist forced entry better than the Gen 2. To open it, drop the tailgate and pull the release cable.
- Sealed edge to edge: Revised EPDM rubber perimeter seals and tight-fit clamps close the gap between the cover and the bed rails, and on most trucks a dual-action tailgate seal, 13% longer than before, covers the tailgate. Drain tubes carry off water that reaches the rails. BAK's own sheet notes the cover is not airtight, so think weather-resistant, not sealed.
- Multi-layer aluminum panels: Aluminum top panels sit over high-density polymer cores on aluminum side rails. BAK says the Gen 3 panels are 22% stronger than the original MX4, and the closed cover is rated at 400 lb, evenly distributed.
- Folds to the cab, drive open: Fold the panels to the cab, strap the cover to the buckles at the bulkhead and drive with the bed open for tall loads. Flipped fully upright, prop rods hold it against the cab on rubber bumpers. BAK says it is the only hard fold that leaves your 3rd brake light visible in every position.
- One-person install: Click-in clamps hold the rails to your bed rails, with no drilling on most trucks, and one person can do the job. BAK says the new click-in design cuts install time by 12%.
- The original hard-fold cover: BAK says the MX4 defined the hard-folding category and calls it America's best-selling truck bed cover. The Gen 3 version (model year 2025) sits flush with the bed rails and wears a textured matte black finish on every surface.
Description & Fitment
The BAKFlip MX4 Hard Folding Tonneau Cover fits the 2005-2015 Toyota Tacoma with the 6'2" bed. It is for owners who want a textured matte black hard cover that sits flush with the bed rails and is rated at 400 lb spread evenly. The multi-layer aluminum panels fold toward the cab, and BAK's patented auto-latch locks each panel as it closes. The cover carries a 5-year limited warranty.

About BAK Industries
BAK makes hard tonneau covers. BAK bills itself as "America's #1 truck bed cover."
The range splits into BAKFlip hard folding covers (MX4, MX4 EZ-Lift, MX4 TS, G2, F1 and Fibermax) and Revolver hard roll-ups (X2, X4s and X4 TS). The MX4 is the aluminum-panel BAKFlip that BAK calls America's best-selling truck bed cover; the MX4 TS adds T-slot rails and the MX4 EZ-Lift adds a lift-assist system.

Frequently Asked Questions
Will this fit my 2005-2015 Tacoma?
Yes, if it has the 6'2" bed. Measured along the floor, that box is about 73.5". Measure along the bed rail from the bulkhead to the closed tailgate, and note it is not for the 5'1" bed (BAKFlip MX4 448406). If you are unsure, send us your VIN and we will confirm.
My truck is right at a model-year change. Which one do I need?
This part covers the 2005-2015 Toyota Tacoma. 2016-2023 trucks with the same bed take BAKFlip MX4 448427. Go by your truck's model year, or send us your VIN.
What changed with the Gen 3 MX4?
BAK lists stronger panels (high-density polymer cores, 22% stronger than the original MX4), re-engineered lock parts that resist forced entry better than the Gen 2, revised EPDM perimeter seals and tight-fit clamps, a dual-action tailgate seal 13% longer than before, re-engineered prop rod clips, and a click-in design that it says cuts install time by 12%.
Will it keep rain and snow out of the bed?
It is built to: edge-to-edge seals and tight-fit clamps close the gap to the bed rails, and drain tubes carry off water that reaches the rails. BAK's own install sheet says the cover is not airtight, so plan on weather-resistant rather than sealed. Clear snow and ice off before you open it; that is a warranty condition too.
How much weight can it hold?
BAK rates the closed cover at 400 lb, evenly distributed. BAK's sheet also says not to drive with objects on top of the cover or tie cargo to it.
Can I drive with it folded open?
Yes. Fold it toward the cab and attach the straps to the buckles at the bulkhead, pulled snug, and you can drive with the bed open. The cover must be secured at all points while the truck is moving; that is a condition of the warranty.
Installation
- 1/2" wrench or socket
- Phillips screwdriver
- Scissors or a utility knife
- Isopropyl alcohol
- 5/8" drill bit and drill
- T-30 Torx driver
- 3/8"-drive short extension and ratchet
Here's the short version. Follow BAK's install sheet (below) for your truck's exact clamp positions and settings.
- Seal the bulkhead. Remove the bulkhead utility-rail end caps on both sides, then clean the top of the bulkhead with soap and water and stick the seal from one edge to the other.
- Load the utility rails and route the drains. Remove the factory end cap from each utility rail (and any cleats), slide in three T-nuts and refit the end cap. Fit the drain tubes to the front of the side rails and run each one through a 5/8" hole drilled in the top corner of the wheel well, after checking underneath that nothing is in the way.
- Bolt on the rails. Set each side rail with the drain fitting toward the cab, pushed against the bulkhead, and bolt it to the T-nuts through the clamps with a 5/16" flat washer and hex bolt at each spot: one clamp 12" from the bulkhead, one in the middle and one as close to the tailgate as possible. Tighten to 10 ft-lb with a 1/2" wrench or socket.
- Prep the cover. Slide the two cover retainer clamps into the track under the cab end of the cover, one per side. Peel the liner off each gasket, stick it under a buckle end, and screw the two buckle ends into the pre-drilled holes on the front header panel with the screws and nutserts. Hand-tighten only; don't use a screw gun.
- Set the cover in place. Lay the folded cover on the side rails at the cab end, centered between them, and turn the retainer clamps clockwise until the lock washer is snug. With the cover still folded, clean the spots for the cab bumpers with soap and water, then isopropyl alcohol, let them dry and stick the bumpers along the top edge where the cover meets the cab.
- Unfold, adjust and check. Unfold the cover toward the tailgate and center every panel side to side and front to back; the rear edge and tailgate seal rest on top of the tailgate with a 1/2" overlap. With a power tailgate, make sure it still works with the cover closed. Release each latch to check it engages the rails, then re-tighten the retainer clamps. BAK's warranty asks you to re-check every clamp after your first week of driving.
