I'll share all my trucking experiences (both great and gross ones) with you. I have a garage full of tools to fix and renovate trucks and a freezer full of ales. Do you want to join me?

BAKFlip Fibermax vs MX4: Differences in features


Edge: MX4 tonneau cover

The MX4 tonneau cover is made of aluminum panels with a matte-black powder top finish. Combining these, this hard folding tonneau cover will offer an ultra-low-profile appearance to your truck.

Its rail end caps, corner caps, elevator bolts, and clamps are also finished matte-coated to offer the ultimate sleek texture.

The exterior of this tonneau cover can be either, painted, polished, or chromed to offer an attractive final touch. Combining these features, this MX4 cover offers a sleek, patented, and flush-fit design.

Though the fibermax tonneau is also made of an aluminum panel, its top surface is finished with FRP for a gloss-black look. An exciting benefit of these FRP panels is that they remain cooler under direct sunlight.

This tonneau cover flushes with the truck bed to offer a snappy and low-profile outlook. Because of the FRP construction, the fibermax tonneau is slightly thicker than the MX4.

Compared to these two, the MX4 tonneau is better due to its matte black coat and its more sleek and attractive design.


Edge: MX4 tonneau cover

With a combination of industrial-strength aluminum panels and premium matte-black finishing, the MX4 tonneau is highly solid and durable.

Despite this, its other attachments are also resistant to dents, scrapes, and UV light. It also has rubber bumpers and pre-molded die-cut panels that absorb shock during driving over rough roads.

Fibermax, on the other hand, is constructed with high-grade aluminum panels and FRP coating. This tonneau cover is also resistant to scratches, dents, and UV radiation, as well as shock. Despite this, the fibermax tonneau is thicker than the MX4.

Between these two, the MX4 is considerably more resistant to scratches and dents due to its matte-black texture. The coating also makes the tonneau more durable than its counterparts.


Edge: MX4 tonneau cover

The MX4 tri-fold truck bed cover allows locking it in three different positions. It has string latches under every panel that needs to be pulled towards the cab to fold up.

The tonneau also has buckle straps to secure the panels efficiently in a 2/3 position. But if you need full bed access, you have to lock the panels in a vertical position with the back window using prop rods. 

An impressive feature includes a dual-action tailgate seal with an injection molded latching system. It means you can shut the truck bed cover with the closed or open tailgate.

On the other hand, the Fibermax tri-fold tonneau cover, on the other hand, allows locking partially in two positions and one for complete bed access.

It also has string latches to unfold the panels and buckle straps, as well as strut rods to secure the panels and get full bed access.

Despite this, the fibermax tonneau has a flap tailgate seal and an aluminum latching system to pull the last panel to lock the tailgate. However, you can’t close the tailgate after shutting it.

Considering the performance, both of these tri-fold tonneau covers are equally efficient. However, the dual-action tailgate seal of the MX4 tonneau keeps it top over its counterparts.

Fibermax is also highly resistant to water and includes water drainage side rails and a drain tube. It also has EPDM rubber seals and hinges to keep the loads dry during extreme rain.

When it comes to water resistance, both tonneau covers are equally functional and protective as they have a similar design.


Edge: MX4 tonneau cover

The MX4 hard folding tonneau cover is considerably more durable. As a result, the manufacturer confidently offers a 5-year warranty.
