BAKFlip MX4 Features and Benefits

The BAKFlip MX4 isn’t just about protecting cargo—it’s about making your truck more functional every day. Here’s why truck owners choose it.

Many owners report improved fuel economy from reduced aerodynamic drag, and the cover significantly increases resale value.

Unlike soft roll-up covers with minimal security or expensive retractable systems needing constant maintenance, the MX4 delivers premium protection at a fair price.

BAKFlip MX4 Installation

Good news—the MX4 is one of the easiest tonneau covers to install. Most people get it done in under 30 minutes working alone.

What’s in the Box

Everything you need comes in the kit: mounting hardware, clamp assemblies, rubber seals, prop rods, and clear instructions with photos.

No need to buy extra parts or make a second trip to the hardware store.

How Long Does It Take?

The new Gen 3 click-in rail system is 12% faster to install than older versions.

Most folks finish in 25-35 minutes. First-timers might take 45 minutes, which is still pretty quick.

Tools You’ll Need

Just basic stuff you probably already have: a socket wrench set and maybe a screwdriver.

No drilling required on most trucks, so no power tools or permanent modifications to worry about.

The Installation Process

Start by positioning the aluminum side rails on your truck’s bed rails.

The click-in clamps secure everything with hand-tightened bolts—seriously, no drilling on most models.

Next, stick the dual-action tailgate seal on the inside edge of your tailgate using the adhesive backing.

This seal is longer than on older models, so it does a better job keeping water out.

Now place the folded cover panels onto the rails you just installed.

The panels come pre-assembled and ready to go. Just attach the prop rods that let you fold everything against the cab.

Make some minor adjustments to line everything up and make sure the latches work smoothly.

Test it a few times—open, close, latch, unlatch—just to make sure everything’s working right.

How the BAKFlip MX4 Performs

The MX4 is built to handle whatever you throw at it—scorching summer heat, freezing winter cold, and everything in between.

Weather Protection

Those EPDM rubber seals create a tight barrier all the way around the cover.

They stay flexible from -40°F to 180°F, so they won’t crack or get stiff in extreme temperatures.

Built-in drain tubes channel water away even during heavy rain.

The dual-action tailgate seal is where a lot of water tries to sneak in, and this one’s 13% longer to block it better.

Most people say their beds stay bone dry in normal rain and snow.

Pressure washing or a really nasty storm might let a tiny bit of moisture through the panel seams, but that’s normal for any hard folding cover.

Weight Capacity

When parked, you can load up to 400 lbs on top of the closed cover—as long as it’s spread out evenly.

Great for throwing lumber or camping gear on top when you need the extra space.

Those reinforced aluminum panels with polymer cores don’t sag, even with heavy stuff on them.

Just don’t pile everything in one spot or go over 400 lbs total, or you could damage the panels.

On the Highway

The low-profile design cuts down on wind noise and drag at highway speeds.

Some truck owners notice a small bump in fuel economy compared to driving with the bed open.

You can safely drive with the cover folded open too.

The prop rods and latches keep everything locked in place, even at 70+ mph.

Daily Use

Opening it up is super easy. Drop your tailgate, pull the release handle, fold the panels forward.

The heavy-duty hinges let you do it all with one hand.

Only need the front part of your bed? Fold it two-thirds of the way.

Need the whole bed? Fold it all the way to the cab and lock it with the prop rods.

Your third brake light stays visible no matter what position the cover’s in.

Closing is just as simple. Fold it back and each section automatically latches as it settles.

Raise your tailgate and everything locks up tight.

Keeping It in Shape

The MX4 doesn’t need much maintenance to keep working like new.

Wash the panels every few months with regular car soap and water. Skip harsh chemicals or scrubbing pads.

Hit those rubber seals with silicone spray twice a year to keep them from drying out.

Clean out the drain tubes now and then so water flows through properly.

Check that the bolts and latches are tight every once in a while.

The matte aluminum finish takes care of itself—naturally resists scratches and UV damage without any special treatment.

How waterproof is the BAKFlip MX4 tonneau cover?

The cover supports up to 400 lbs of evenly distributed weight when parked, accommodating light cargo rack systems and accessories.

How does the BAKFlip perform in winter weather?

Snow and ice may accumulate on the matte black surface, but the BAK tonneau cover panels won’t crack, warp, or fail in freezing conditions.

Can I remove the BAKFlip MX4 if needed?

Yes, the complete BAKFlip assembly can be removed in approximately 5 minutes for hauling oversized cargo.

Simply loosen the mounting clamps, disconnect the prop rods, and lift the folded cover assembly off your truck bed.
