10 Best BAKFlip MX4 Hard Folding Truck Bed Tonneau Covers
If you own a pickup truck, you already know the bed is one of its most useful parts—and also the most exposed. Rain, dust, tools, luggage, and even groceries all need protection.
That’s where a hard folding bed cover like the BAKFlip MX4 comes into the picture. Over the years, I’ve tested and installed many truck bed covers on real trucks, not just for photos but for daily driving, long highway trips, and job-site use. The MX4 is one of those covers that keeps coming up in real conversations with truck owners, mechanics, and installers.
The MX4 is known for its low-profile design, solid aluminum panels, and ability to fold all the way up without blocking the tailgate or bed access. It’s popular with both work truck owners and daily drivers because it balances strength, weather protection, and clean looks.
Instead of pushing hype or calling something “best” without proof, this article breaks down how the BAKFlip MX4 performs in real use-how it feels to open and close, how it handles rain, how secure it really is, and what kind of truck owner it makes sense for.
If you’re comparing options or trying to decide whether the MX4 fits your needs, this is where you’ll get honest, practical insight before spending your money.

10 Best BAKFlip MX4 Hard Folding Truck Bed Covers – Reviews with pros and Cons
Before diving into individual reviews, it’s important to understand what makes the BAKFlip MX4 different from other hard folding covers and why small details matter. On paper, many covers look similar. In real life, they behave very differently once installed on a truck that gets used every day.
In the following reviews, I focus on features-how the cover fits, how long installation really takes, how it reacts to heavy rain, highway wind, and repeated folding. I also look at the small things truck owners care about: whether it rattles, how secure the clamps feel, how easy it is to clean, and if it still looks good after months of use.
If you’ve ever bought a truck accessory and felt disappointed after installation, this section is meant to prevent that. By the time you finish reading the reviews.
