The BAK BAKFlip MX4 EZ-Lift (part 450324) is a hard folding tonneau cover for the 4'5" bed of the Ford Maverick. It carries the MX4 design forward and adds an assist system that the manufacturer says reduces the effort needed to open the cover. The panels use multi-layer aluminum over a high-density polymer core, finished in a textured matte black.
The main reason to pay for this version over a standard hard fold is the opening action. The oversized paddle handle is the only part you need to grab, and the latch releases on its own as the cover lifts. The manufacturer also says the cover does not hide the third brake light or the integrated camera in any position, and folding it flush against the cab opens nearly the full bed for long loads. Integrated perimeter seals and tight-fit clamps are the manufacturer's answer to water intrusion, which matters more than price when you compare it with cheaper soft or clamp-on covers.
Shoppers searching for a 2021-2026 Ford Maverick 4'5 bed hard folding tonneau, an EZ-Lift tonneau cover, or a Maverick tonneau install without drilling will find the core details below. The manufacturer describes a bolt-on, no-drill mount that can be done in about 30 minutes with no extra helper needed, so this is a realistic weekend upgrade.
The manufacturer states the design does not block the third brake light or the integrated camera in any position.
The manufacturer says the cover mounts with clamps and requires no drilling for most makes and models, which is the case for this bolt-on design.
Owners on user forums report light leaking at the corners and bulkhead on some installs. They suggest adding gasket material in the corners, running clear silicone between the bulkhead and gasket, and checking the tailgate seal at night with a flashlight.
The manufacturer's install sheet for the MX4 platform says to start at the front and place the first clamp about 6 to 9 inches back from the bulkhead. Seat each clamp fully into the rail with its teeth aligned to the rail slots, and keep the rail clamped square. If you are mounting against a painted rail or spray-on liner, the install sheet calls for spacer shims on the clamping surface. Owners on user forums note that the tailgate seal fins should rest on the tailgate, and that the instructions reference a 1/4-inch clearance, so check that before you tighten everything down. After install, run a nighttime flashlight check along the tailgate seal to catch any gaps.
