How to Install the BAKFlip MX4 Hard Tonneau Cover on a 2020 Ford F-150


Hey, everybody. How's it going Today, we're gonna be going over and showing you how to install the BAKFlip MX4 Hard Tonneau Cover here on our 2020 Ford F-150. So here's what our tonneau cover looks like installed. The first thing we're gonna notice, it's a super low profile cover, so it really doesn't stick out much above the bed rails at all. The second thing you're gonna notice is the actual color. So it has a nice black powder-coated finish, which really blends in well with our bed here.

It actually matches quite well to the bed rail caps and the tailgate cap. So each of our three panels here are gonna have an aluminum construction as well as the black powder-coated finish we mentioned earlier. I also like to point out that there's gonna be foam in between the two aluminum panels here, which is gonna help add extra durability and strength. So the MX4 is actually a hard tonneau cover. Now, there's two different types of tonneau covers.

We have soft tonneau covers and hard tonneau covers. Now, soft tonneau covers are a great option. They're easy to use. They're lightweight. However, they do have one drawback, and it's that they don't provide a lot of security 'cause I mean, let's face it, anyone could pretty much come up there, just take a knife, cut the vinyl top, and get whatever they want out of your bed.

You're not gonna have that concern here with a hard tonneau cover. We talked about earlier these very durable aluminum panels, you don't have to worry about anybody being able to break these and get into your truck bed. If you have a locking tailgate like this truck here, you're not gonna have to worry about anyone being able to lower the tailgate and open the cover because you do have to have access inside the bed to be able to open it. So on the bottom, we're gonna have a pull string here. We're gonna have one on either side.

You only need to pull one. That will release the locks, and then we can begin folding the cover back. We'll have another pull string here as well as another one here as well. And we can actually rest it up against the back cab on our truck here. We can also secure it in this position here using the prop rods that are built into the rails. We'll simply just undo one of those. We'll loosen this hand knob, slide our bracket up, place our prop rod in, let the bracket go over the prop rod, and then just tighten down the knob here. That will secure our cover in this position if we need to haul any larger items in our truck bed. So no tonneau cover is gonna be completely waterproof, but I really feel this one does a great job of helping keep out as much water as possible. We have these rubber steels running along the outer edges of the cover. We also have a built-in drain channel, which leads to some drain tubes here that lead down into the truck bed and then out in one of the grommets to make sure we clear all that water that does get inside these rails here. That way, it doesn't end up in the truck bed. So for additional security, we actually have a little cam buckle strap here attached to the cover that will secure it to these buckle ends here while it's in the folded position. So another thing I really like about this cover, it's definitely very refined. Everything fits nice and secure to the truck bed here. We have these auto-latching mechanisms. They take all the work of securing the cover to the rails out of the equation. We get a nice positive click when we drop it. You can see the weight of the cover actually helps us in engaging those locks. As you can see, we can pull up on there. It's nice and secure to the rails. So in regards to installation, this one's pretty simple. We don't need a lot of tools, and we don't technically have to make any modifications to the vehicle, which will sort of vary depending on how we install our drain tubes. But aside from that, everything's pretty straightforward. It's definitely something I feel you guys can do at home. Let's go ahead and walk you through this now. So for the first step of our installation, we need to get inside the truck bed here. We need to come to the bulkhead. So if you're not familiar with that the bulkhead is gonna be the top rail on our bed here directly behind the cab. This here is our bulkhead. So we need to identify whether we have a factory drop-in bedliner. So a factory drop-in bedliner is gonna be this plastic liner that sorta fits over the bed here. If we have this, we can proceed to the next step. But if we just have the factory-painted bed surface here, we'd actually need to go ahead and clean this off and apply our bulkhead seal, which looks like this. So we'd actually just place this on the very inside edge of the bed rail here. We'd run it all the way across and then we'd cut off the excess. It has a adhesive back side there. So once we clean it off, we just stick it on there, press it down, and we're good to go to head to the next step. Because our truck has a drop-in bedliner, we're gonna go ahead and proceed to that next step now. So now we're ready to install our bed rails. So we're gonna have two bed rails. They're gonna be a little bit different. What we're gonna be doing is looking for the silver bracket here. So the silver bracket is gonna be at the very closest edge of the cab and then towards the inside. So, basically, what I mean by that is when we stick our rail on, that silver bracket should sit up in this corner here, just like so. So we're gonna use one hand to hold the rail in place, then we're gonna come up with a tape measure here. We're gonna try to find a suitable location for our first clamp. So I recommend six to nine inches from the back corner of the bed there. So once we have that general spot, we're gonna take one of our clamps here. We wanna make sure that the side of the nut is facing out towards us. Then we're simply gonna find that spot there on the bottom and clamp it in place. We'll take a 14-millimeter socket to tighten this down to hold everything. Now, we're gonna come to about the center of our bed directly up from this wheel well here and about the center to place our second clamp. Now, we wanna make sure that while we're installing these clamps, number one, we're pressing down on the bed rail, and, number two, you can see the little teeth up in here, we need to make sure that aligns with the grooves in the bottom of our rail. So just make sure you're pressing that all the way up when we're tightening them down. And, again, we're not tightening them super tight now. We're just gonna get them in place loosely. Now, finally, we have our rear clamp, which will be about six inches in from the tailgate. Now, we'll go ahead and repeat the same process on the other side. So now once we have both of our rails installed, we can come back and actually tighten down our clamps fully. Now, if you have a torque wrench, we can use this. But more than likely, you guys don't, so you can just use a standard ratchet and just tighten it snug and then about another half a turn. So now we're ready to go ahead and set the cover up into position. Now, on your cover, you're gonna notice you have this small little panel here. This is actually gonna go up towards the bulkhead. So once we get it in the correct position, we're gonna go ahead and line everything up. So if we take a closer look at this smaller panel here, you can see we have a hole here. That actually needs to align with the slotted hole in our silver rail here. So we'll go ahead and get it into position as best we can. Just sorta look down in there to see if everything is lining up. Looks like we actually have a little cover on the back we have to take off. But that should be pretty good where it's at there. The next thing we're gonna do is install our buckle ends. They look like these. These will be installing into the two pre-drilled holes we have on the smaller flap here towards the cab. So they simply line up like that. We have a little nut insert that if we lift the panel up, it will go into the bottom. Then we can take one of our screws here, place it through the adjacent hole, use a Phillips head screwdriver to tighten that down. So we wanna make sure that we use a hand screwdriver only to tighten these. We don't wanna use a screw gun 'cause we're just gonna get them snug. We don't wanna overtighten them. Now that we have both of our screws tightened, we'll simply just repeat that same process for the other buckle end on the other side. So now we'll take our flat bolt here. We're gonna place it through the large hole, again, in this front panel. We're gonna try to get that to line up with that slot that we showed you earlier in that silver bracket. We'll do that on both sides. So now we actually need to go underneath the cover. We're gonna secure that flat bolt that we just installed. We are gonna need a couple different nuts to do that. We're gonna need a rubber washer. That's gonna go on first. Follow that up with a flat metal washer, then a split lock washer, and then our hand knob. So let's go ahead and crawl under there now and tighten it down. Keep in mind we don't wanna torque it fully. We're just gonna loosely install them. So we got that on there. We'll give it a couple more turns here. We'll hop over to the other side and do the same thing. So now we're gonna go ahead and just unfold the panels here to make sure everything lines up. So once we get the cover unfolded, we're gonna go ahead and put up our tailgate. Ideally, we want this last flap here to overlap the tailgate a little bit to keep water out. As you can see here, we have a good gap. So what we're gonna do is the reason we left those knobs loose earlier, we actually are gonna pull the cover back towards us to hopefully cover more of the tailgate. You wanna make sure you pull evenly on both sides. Now, we'll raise our tailgate back up. As you can see there, we have coverage and there's no longer a gap. So now that we know we have the cover squarely in position, covering both the tailgate and the header, we're gonna go ahead and dive back underneath and re-tighten those hand knobs that we showed you earlier. So the next thing we're gonna do, we're gonna be installing our cab bumpers. They look like these. These are gonna protect our back window from this metal rail here while we have the cover folded up. So we're gonna come in an inch here, probably about an inch and a half. The instructions say it needs to be at least an inch away from this outer edge of this rail here. So we're gonna come in an inch and a half, maybe even two inches, and install that first bumper here. So we'll just simply peel off that adhesive backing and then stick it into place. We'll go do the other side, and then we'll have one more, which we'll just center in the rail here. Now, we can go ahead and fold our cover up against the cab. And now we're ready to install our drain tubes. So on the bottom edge of this cover, there's gonna be a little tube that this end of the drain tube will fit over. And then the other end, we obviously need to route outside of the truck bed. So if you have a drop-in liner like we do here, it's gonna make things a little bit more difficult, but essentially we need to locate a grommet that we can either remove or drill through in order to route our drain tube. That way, all the water that does get in the truck bed is able to escape. So if you have a drop-in bedliner, we've already went ahead and identified where the grommets are for you, we're gonna see these little oblong cutouts here. We actually need to drill through both the plastic bedliner and the grommet behind that. So if you have a step drill bit, that will work. Or if you have a larger 7/8-inch drill bit, we can use that as well. You need to be careful, though, while we're drilling through both the bedliner and that grommet that we don't go too far and pierce the back of the cab behind the header here. So we're gonna be very careful. We'll go ahead and drill out that hole. If you don't have a drop-in liner, this is obviously gonna be a lot easier 'cause we'll be able to drill straight through the grommet there. Now, I can stick one end through the hole that we just drilled, and then make sure we line it up just right to get it through both the grommet and the outer edge of this bedliner. Then we can take the other end and attach it to that tube on the bottom of the cover, just like that. And now that we have our drain tubes successfully installed, that's gonna do it today for our look and installation of the BAKFlip MX4 Hard Tonneau Cover here on our 2020 Ford F-150..
