This sturdy cover has a great look without compromising any durability. BAKFlip MX4 comes with a full aircraft-grade aluminum frame which ensures long-lasting durability. The black powder coating on the frame protects it from rust and corrosion. The panels are made out of aluminum with the BAK industry’s heavy-duty premium density core. The textured aluminum exterior also gives them a great look. These matte-finished panels are scratch, rust, and UV resistant.


BAK industries are popular for their low-profile design in tonneau covers. BAKFlip MX4 is also a low-profile cover. The cover doesn’t add any extra height to the truck bed as it fits inside the truck bed rails and also sits flush with the tailgate. In fully open position this tonneau cover will not cover your third brake light.


BAKFlip MX4 tonneau cover is quite easy to install. It neither requires a drill nor any professional tool. You will only need a wrench and socket to install the cover. All the other required hardware is included in the box. Though installing the tonneau cover doesn’t require any drill, you may have to use one to drill holes (if there aren’t any) in your truck bed for the drain tubes. Following the instruction provided by the manufacturer will help you install it within 15-20 minutes. You can also read our article on how to install a tonneau cover.


Usually any type of hard tonneau cover provides good security for your truck bed. For this tonneau cover, it is even better. As the frame and also the panels are made out of aluminum there is no confusion about the high security. The cover locks with the tailgate in fully closed position and can’t be opened without unlocking the tailgate. So, while locked you can drive or leave your truck anywhere without thinking about your cargo. These panels along with the rubber seal installed between the truck bed and tonneau cover will also provide a good seal against water and dust for your cargo.


This tri-fold tonneau cover folds in four different positions and in each position the cover is locked with the integrated latch system. This tonneau cover also offers 100% bed access in fully open position, so you will get full access to your truck bed. If necessary, removing the tonneau cover is also quite easy.


  • 100% bed access
  • Solid and increased durability
  • Easy and no-drill installation
  • Improved latch system
  • Integrated drain tubes
  • Integrated prop rod
  • Good seal against water and dust
  • High security for truck bed


  • When the cover is fully closed it cannot be opened without unlocking the tailgate.
  • No integrated lock, it locks with the tailgate.
  • The drainage channel is open at the tailgate end and can dump a little water while driving in a rainy situation

Important Features

Despite being quite lightweight than other hard tonneau covers it can hold up to 400 lbs. or 180 Kg of evenly distributed weight. There are two drainage channels built into the frame. These channels help draining water outside through the drain tubes. BAK includes a weather-stripping tape with the tonneau cover. The weather stripping is pretty easy to apply and gives a good seal against moisture. If your truck has a drop-in bed liner you might not need the weather stripping. The MX4 also has two integrated prop rods. These prop rods hold the cover up-against the cab when it’s flipped up or in fully open position. You can drive your truck at highway speed by locking the prop rods correctly, while the cover is in fully open position. New improved cab bumpers are also included to protect the cab from scratches. The triple-fin tailgate seal is also a notable feature for which you are capable to close the tonneau cover whether your tailgate is open or closed. There is no integrated lock for the cover, it locks with the tailgate. Which also gives you the disadvantage of not being able to open or flip it without unlocking the tailgate.


All the good products can also have some small disadvantages and BAKFlip MX4 is one of those good products. There is a small issue of drainage channels built into the frame. These channels are open at the tailgate end, so if you drive at high speed during rain a small amount of water may get inside because of the wind. Adding some caulk (or, anything that will hold the water) at that side can easily solve the problem.


At this point, you may have already understood that the BAKFlip MX4 is an overall champion in every category. BAK industries didn’t do any compromise with their built, design, or material choice. The mentioned disadvantage is also a rare thing to happen and it’s solvable in a minute. And the cover locking with the tailgate is your decision to choose it as a feature or downfall. Though we will recommend this tonneau cover to anyone, it’s always your decision to buy or not.
