Video Transcript for Rhino Rack Vortex Aero Crossbar Installation - 2021 Ford F-150

How's it going everybody, it's Ethan here at etrailer. Today we're gonna be taking a look at and showing you how to install the Rhino-Rack Vortex Aero Roof Rack System on our 2021 Ford F-150. So with the F-150, obviously we have a good amount of bed space, but if you wanna get something longer or larger up there and maybe couple this with like a ladder rack to give some longer loads like a ladder or a lumber or on the sports and rec side, maybe you have a larger kayak you wanna get where you need it to go, a roof rack system like this one is gonna be a great solution for you. So let's take a closer look. The roof rack is going to have a weight capacity of 165 pounds. It's going to fit on our roof with the fit kit that we'll show you in the installed portion.

But 165 is gonna be a pretty solid or pretty common number that you see with roof racks like this, which is gonna be fine for most of the things you wanna get up there. You just wanna double check and make sure that your roof weight rating is in that same ballpark. Make sure you know what each of those are and go by the lowest ready component just to be safe. The crossbars we have on our system right now are gonna be 59", which is a solid length. We stay pretty much well within the width of our vehicle overall.

They're going to be elliptical so they taper on both ends to cut down on some of that wind noise and drag. But anytime you put something up on the roof, you're gonna deal with that. Luckily, we also do have a vortex strip on the top which is how the bars get their name. So that's going to help again cut down on some of that wind noise, otherwise we just have that open channel up here. Speaking of that channel though, that's gonna be great for your T-track accessories.

If you have those, you can slide those in. But with the strip you are going to have to trim it up if you wanna leave this strip in with those accessories on. So it's not a horrible idea to just grab another strip if you want to, in the event that you do end up doing some trimming. On our end cap here, we do have a plastic lock which we can use to unlock or lock our end cap but you can upgrade those to metal if you'd like. On the underside, you do have the option to use a measurement strip that you are gonna trim up and put wherever your towers are not.

In our case, this is just for demonstration and we'll talk a little bit more about that in the install portion as well, but that'll cut down on that whistling noise underneath as well. And using the provided key, we can take our end cap off and just show you how that works. So it's just a metal lock core there that will expose our fit kit hardware. So as long as our end cap is on and it's also locked up, no one is going to be able to access your fit kit hardware and remove the rack from your roof. From here I'm just gonna get a quick measurement to give you an idea of how much height you're going to be adding to your roof with the system. So from here in the middle, you're going to be looking at adding about 4-1/4" from the highest point. So if you're thinking about storing this in your garage, especially if you have something on there, add about 4-1/4" to whatever that's gonna be to find out whether or not it will fit in your garage or if you'll go anywhere where there might be some clearance issues. The roof rack system is gonna be made out of an anodized aluminum so it's gonna be really lightweight, easy to work with, but also very durable and rustproof at that point. It's got a nice matte black finish so it looks good. I think it fits the aesthetic of our F-150 really well. Overall, the install portion isn't too terribly difficult. It can be a little bit tricky, but you just need to be patient. Use the measurements that the instructions give you and make sure that you know where everything is gonna go. But if you need a little bit of help with that process, we'll walk you through it right now. To get started, the first thing we'd like to do is to slay everything out so that we know where and what it is. So we have our crossbars, we have towers, our fit kit, the clamps, and the hardware. We've got the pads and the bases for our towers. We have the tools and I would recommend picking up some kind of fabric tape measure as well as a regular tape measure. And then we have this measurement strip that comes included that we'll have to trim up according to our needs and definitely keep the instructions close by 'cause we will have to reference those often. But we'll begin by removing the end caps on our crossbars. We are going to use this plastic key to fit into the end cap. Just turn it and pull it out as long as we have it rotated fully, and we need to remove that in order to get our towers on. So we're going to line up this metal plate here with the underside, with the channel underneath our crossbars and just slide those on. And now is when you're gonna use that measurement strip. So for our case, ours has already been trimmed up so we can't use it effectively but you're gonna basically line it up with your tower, find the measurement on your instructions. In our case, we're looking for 169, so I'll get that roughly to where it needs to be. In your case, you could actually use the full measurement strip and trim it up if you need to. We repeated that process on the other side. We just slid our tower under this channel here and line it up according to the measurement, removed our end caps and now we just need to replace those real quick. Again, just put 'em on and tighten 'em down with the key. From here, since we're doing our front crossbar, just be sure to reference the instructions but we're going to attach one of our base pads to the rest of the base, and we wanna make sure you can see this arrow on here. We wanna make sure that ends up facing forward, so in our case, we're going to get these on and then we'll line it up with the tower. With the pad connected to the base, you can see where these openings are, and where they'll fit on our towers. So from here, again, we just wanna make sure that that arrow is facing forward, and we can snap this on into place. And then we're gonna repeat this process again on the other side. Once our towers are roughly in place, we're going to get a measurement. In your case, you could use the measurement strip. In our case, we would've to trim that up, and this is just for demonstration, so I'm gonna use our fabric tape measure to find that 169 millimeter mark in our case. And now I'm going to use the Allen key provided to tighten this down. As we tighten down, something important to note is that this tool does have a built-in torque spec, so just the way it's designed. Once we start turning, as soon as we see that line straightened out, that's about as tight as we want to go. Once we have our towers all set up, our measurements where we need 'em to be and both bases in place, now we can place our crossbars roughly on our roof, whereabout we think they're going to go. Just a matter of getting them roughly in place for now. And then we're gonna come back and get the measurement to make sure that they're in the right place. From here, again, since this is the front crossbar, I'm going to be using the measurement A in our case, which is 280 millimeters or 28 centimeters from the center of our door jam to the center of the tower. So in our case, I need to slide forward quite a bit. It's gonna be kind of hard to tell for now until I move the other one forward as well. So I'm gonna go to the other side and get that measurement now. Once we have everything in place and all our measurements are good, if your end caps are on, make sure we get those out of the way. If they're locked, go ahead and just use the provided key to unlock it. But now we're going to fit the bolt through this hole here on our clamp and make sure that it threads into that opening there inside our tower. Once you get the bolt here to start threading, it's probably gonna be easier just to use the tool to get it most of the way in. In our case, I'm gonna go to about 70, 75% here. I'm not gonna tighten it down all the way 'cause it might start pulling the whole system towards me, rather I'm gonna tighten this one down, and then I'm gonna go back to the other side, tighten that one down, come back and finish this one up, and then finish the other side up as well just to make sure everything's even as possible. Now that we've gone back to the other side and tighten that one down, I'm gonna finish tightening this bolt here. Again, just using this tool. Once it gets to the point where it straightens out, that's how you know we're at the desired torque. So I'm right about there now. All that's left to do is to replace our end caps and lock those up. So overall, if you're looking for a really effective way to extend your load space, whether that's getting some larger or longer items up on your roof, the Rhino-Rack Vortex Aero Roof Rack System is gonna be a great option for you. We just took a look at how to install it and how it fits on our 2021 Ford F-150.

The order was delivered yesterday, and I got it installed today. The product quality is very good and I am pleased with the fit and sturdiness. Installation went fine. I am slow and methodical with these types of installations. It took me a little less than 2 hours. Many people could do this in around an hour or so with no problems.



by:

The rack fit well and was easy to install. Seems to be made well. The problem is the amount of road noise. I never even put the basket on. It was so loud, it roared. I repositioned it several times but the noise was way too much and I finally just removed it. I spent a lot of money for the rack and the basket and now they are in storage. I wish it would have worked out better because I thought it looked really good.



by:

Fits the truck perfectly and holds canoe tight. Feels very solid and trustworthy.



by:

The roof rack continued to get loose and I lost 2 kayaks going down the highway. I was able to recover them after significant damage. The whole rear rack fell off. Once reinstalled I added numerous straps and continued to stop every 50-75 miles to retighten and adjust so it didn’t happen again. I will not be using these roof racks again.

We originally got this rack system (Custom DK Fit Kit for 4 Rhino-Rack 2500 Series Roof Rack Legs - Naked Roof Item #DK427) mostly for our Kayak racks on our 2015 Ford F-150, which worked great. Then we totaled our F-150 and the racks actually fit on our new 2022 GMC Sierra 2500 HD P/U. We took it on a 16,000 mile trip from the East Coast to Alaska with both 12 ft. kayaks on the top. Through the various speeds (sometimes up to 80 mph), weather conditions, and the high crosswinds of the mid-West, the racks help up perfectly. No issues or problems. I would recommend these to anyone.

Awesome company to do business with! 2nd set of Rhino racks I have purchased from them and it was a smooth transaction both times.

Got it on sale, matches the color of my truck. Same as my roof rack for my former vehicle which is now on my wife's car, however this one actually fits my truck.

2018 Ford F-150

Recently bought a Rhino rack for my 2018 Ford F-150. Took my time, followed instructions exactly, and it fit perfectly. Plan on using the rack to carry my kayaks, especially when pulling my travel trailer. Haven’t put it to use yet but am very pleased with how it fit my truck and appears to make very little noise on the road.



by:

Excellent fit for my truck.Absolutely necessary to carry my surf rods on the top of my truck. Highly recommend this product if you don’t want your paint scratched. Thank you Paul B at etrailer for your dedication to customer service support. I’ll be back. I wish I had some photos.

Ford F-150

I was not disappointed with my purchase. I put the racks on my F150, that I bought for surf fishing along the Jersey beach. The racks are performing well and even though I thought that the initial cost of the racks was a little steep, my Rhino Racks are worth every penny.



by:

Great Product , Super Excellent Customer service Thank's

Nissan Versa

This rack works perfectly on my Nissan Versa for carrying my two Perception Sound 9'6" kayaks. The Rhino-Racks look good to me. The kayaks can rest directly on the rubber pads on the rails, unlike the Yakama racks I had in the past that had bare pipe rails. Also, I expect I can buy parts to adapt this product to a different car without having to buy new towers. I am sorry there are not hooks or loops to attach bungees when carrying lumber. They are noisy in the wind, but less so when carrying the kayaks.



by:
2018 Ford F-150

I installed the rack on a 2018 F150 SuperCab. These racks are really nice medium load racks, well built and easy to install. If I followed the instructions the pads on the front cross bar would not sit down in the drip channels. I narrowed the front leg locations by 5mm per side or a total of 10mm or approximately .4". I sent the pics to Rhino Racks Engineering Department but have not heard back to see if they liked my fix. I like it! I recommend getting Rhino Racks approval before making these mods but that's what it took for mine to fit.



by:

This is my second Rhino-Rack. They go on very easily and hold the bikes/kayaks and even an extension ladder very well....thanks for a great product



by:

Great customer service throughout the purchase and delivery. I installed my new Rhino Rack the same day it was delivered. Looks great... Even better with my kayaks on it.



by:
