Shared Features

It is good to know the similarities and differences between the two products before making a purchase decision. As mentioned in the introduction, both the tonneau covers, Gator EFX and Bakflip MX4, have a common function to perform, therefore some of the features of both are completely identical as mentioned below:

Construction: Both the Gator EFX and Bakflip MX4 covers are made in the USA and constructed from heavy-duty aluminum panels with built-in scratch resistance. Both the covers are constructed with foldable panels and feature a low-profile appearance.

The Latching System: Both the Gator EFX and Bakflip MX4 systems rely on the same automatic latching system to secure them in place. Each of these products uses a latch that locks the cover in position when the panel is closed. To open the cover, the string latch needs to be pulled to fold the cover toward the truck cab to open it to access the cargo. When the cover is folded back to shut it, the panels automatically latch into place.

Water Resistance: Each of these two cover systems comes with a protective layer designed to help repel water during rainstorms, working to keep the bed of the truck dry. Water that rolls toward the rail system holding the covers in position runs down through a set of drain tubes, redirecting it away from the interior of the truck bed.

Installation system: Each of the Gator EFX and Bakflip MX4 tonneau covers, get installed with clamping rails that don’t require any drilling or special measures to to get those in place. Simply, the clamps need to be tightened into position and the cover top needs to be locked to the rails for the installation process. Both the covers can be installed on the vehicle within one hour. Both the covers require a connection of the cover drainage pipe to the truck bed drainage via a simple connection.

Update: for more details, read our Bakflip MX4 review



In the case of tonneau covers, the main purchase intent is the ability to protect the cargo from rain, snow, etc. Other goals like aesthetics, ease of installation, and ease of operation is important but not the main criteria.

Although the panels of the Gator EFX have better scratch resistance, keeping in view the main goal of these tonneau covers, which is cargo protection from rain, snow, etc., it is concluded that “Gator EFX” IS NOT able to do the main job efficiently. Its seals start to leak especially after a few months of service. If the seals start leaking, then even though the cover is cheaper, does not matter. The reason of leakage through Gator EFX is the inefficient “flap-type” seal.
