Video Transcript for Rhino Rack Roof Rack Installation - 2021 Subaru Forester

What's up, everybody It's AJ with Today, we're gonna be checking out the Rhino-Rack Vortex roof rack system. It's gonna be on the raised rails on this 2021 Subaru Forester. So roof rack system is an awesome addition to your Subaru just so you can carry more things up on the roof. So, many different things, like if you wanna throw a bike rack up there, you can. If you don't use your hitch or your hitch is already used by something else, you can throw a cargo box up there, maybe a kayak carrier.

A lot of things for different adventures are unlocked once you put these up on your cross rails. And this system is awesome because it just clamps onto your existing side rails. So there's not a full on installation on this. It's pretty easy to put these on and take 'em off if you don't wanna leave 'em there all the time. Look at the bars themselves.

There are gonna be arrow bars. So they are arrow shape design. It's gonna be a black powder coat aluminum on there. So if you leave 'em up on the roof, you're not gonna have any issues with the weather, eroding them, corroding them, or rusting. They're made to stay up here.

One nice thing about this, that it also has the T-track here in the middle with rubber strips to cover that up and the T-tracks can be nice. So you can use clamp-on accessories that go around like that, or ones that slide here in the track. That way there's nothing gonna be underneath those bars. So you have both options. I like that the rubber strip, you will have to peel that and get that cut to however your accessories are.

You can see that ours have a couple spots missing in there. That's where we lined up to add a bike rack on top. So it's just gonna be like that unless we got more rubber strip to fill in those gaps. So there might be a little bit of whistling if you don't have that fully filled out. But if you just use clamp-on accessories, that rubber strip can stay in the middle. And it's not gonna be a problem. A security-like feature would be the end caps here. So you have a special key that unlocks them. So right now I can't take that off so that if I had any T-track accessories on there, nobody can take it off and mess with it when I'm not around. So you can just use this key, turn it, then you can remove the cap and then you have access. And that even goes to protect you taking the clamps off of your cross rails. Now, if you're not wanting just a plastic core in there, you can replace it with a lock core and then get that key. So then it's fully locked up. Now I talked about how easy the installation is. You don't really need any tools except for the one that comes with it, check out how I did it. We're gonna do a little bit of assembly here on the table before we put it up on our roof. Gonna come over here to remove one of the end caps with the key. Like that. Pull that outta the way. Then we'll take our foot and slide in. Make sure these portions go in the track here at the bottom. Now we're gonna make sure this is spaced out enough so we can go over the cross rails on your Subaru. And then we're gonna go ahead and put it on the roof. Carefully, climb up there and set it on the cross rails. I'm gonna use the tool that comes with it to tighten it down, once we've measured out where it should be. We measured from center to center for 24 inches and then we measured about four and three quarters of overhang on both sides. And then we can go ahead and tighten it down once we know that's right. And with that done, we're gonna place the end cap here. That'll complete the installation. Now, let's get some measurements. So we're gonna come here to the top of the bar, measure to the top, from the top of the cross rail to the top of the bar, is gonna be about two inches. So it's gonna stick up a little bit from that crossbar. And then if we come to the middle, go from the the roof to the bottom of the bar, that's gonna be right there at three inches. You're gonna have three inches of space. So just keep that in mind with clamp-on accessories, that's how much space you're gonna have for the clearance. One thing we adjusted for your Forester, was we've brought the bar back just a little bit. That way we could still have access to the sun roof. It still works and you can still use it. Now it will be covered up if you get like a cargo carrier, a rooftop box, it's just gonna overhang and you're gonna lose a little bit of that visibility. Something to compare this roof rack to would be an Inno roof rack. It's gonna clamp on the side rails, just like this one. It's very easy to install. Just like this one. The one thing I kind of like above that one is gonna be it's T-track strip, the weather strip on top, you push down on the accessories. So it pushes that down and then you slide it along there. So you don't have to cut anything to length. You don't have to peel it out and cut it like you do on this one. No matter what you're gonna put up on the roof, it's definitely gonna help you out and either making space in the vehicle or just be able to take those extra gear with you wherever you go. Well, I think that does it. Thanks for hanging out. And I hope this helps..

Rhino-Rack SX Series Legs for Vortex Aero Crossbars - Raised Factory Side Rails - Qty 4 - RRSX100

Average Customer Rating:  4.7 out of 5 stars   (265 Customer Reviews)

Durable nylon legs let you mount Vortex Aero crossbars to your vehicle's factory elevated side rails. Custom-fit leg clamps tighten with included tool for easy installation on your rails. Pair with 2 crossbars to create a complete roof rack.


I purchased the Rhino legs, cross bars and J-style kaya carriers together and could not be more pleased with the combination. The system was installed in an evening and used the next day. The legs were very simple to install on the cross bars and then mount on the vehicle.


Package, both items appeared used, but in good condition. The legs were not in the factory box, but just a eTrailer box. The instructions were hard to follow, even with a little help from YouTube. Just about to test drive to check the noise level. Time will tell, there is soft rubber on the legs and it may be wise to remove these when not in use, especially during Florida summers.


Just what I was looking for for my 2021 MB Metris Cargo Van with Raised Rails, for hauling a 14-foot SUP. I wanted as low profile as possible and the Rhino Rack SX Series Legs and Aero Crossbars looked best. Relatively easy to set up.


Unfortunately, the vortex aero crossbars whistled very loudly on my 2022 Subaru Crosstrek. In addition, I found it difficult to center the crossbars with the SX series legs. And, finally, these legs would not stay tight for more than a day or so.


Using Rhino-Rack Vortex Aero Crossbars, Using Rhino Kayak holders. Also use a Rhino bicycle rear receiver mount. Love Rhino products.....strong, well engineered, low noise, and every part is quality... mounts, straps, etc. Photo is departure picture from last years trip to Big Bend, Texas. We probably put a couple thousand miles on these pieces of Rhino equipment on all types of roads at both Big Bend Park and Big Bend State Park... You really cannot go wrong buying Rhino products. Everything they make is well designed and will not disappoint.

Rhino products are just great products They work today like the day I bought them and they show very little agewear. You really cant go wrong with Rhino products.

Fits my 22 Subaru Outback Wilderness awesome! Great low profile and minimalist design. My only dislike is the bright white Rhino Rack logo on each foot. Sorry Rhino, your name/logo needs way more graphic design; the white silk screen was able to come off with acetone and elbow grease, but I wish the whole rack setup was fully blacked-out from the factory without bright decals or logos. One of the cross bar boxes arrived open/damaged, but contents were fine. Great rack tho!


I haven’t installed rack yet and everything appears to be in order.
* I wasn’t anticipating that Rhino -Rack Sports Ladder Peg (s602) be made of plastic.
Does it have the strength, durability to perform well and not get brittle in colder temps?

I wanted to let you know that the racks to do have longevity in all type of weather and are made to be taken off and on the vehicle.

Easy to install and looks great


These legs with the Rhino-rack Vortex Aero Crossbars - 59" - Black - Qty 2 are a perfect fit for our Subaru Outback Wilderness with good overhang for a kayak loader. Check out the eTrailer video showing the install on a Wilderness. The info on their site is first class and a good reason to buy from them.


I bought the rhino rack rooftop rack a year ago and am very pleased with my purchase. I also added a rhino rack bike carrier to carry my road bike with me. It has performed very well on several camping trips in the past year.


Its been one year since I installed the Rhino Rack crossbars and I have absolutely no issues. The main use is to carry my Kayaks on my 2013 Subaru Impreza utilizing Yakima JayLow kayak carriers. The only caveat is to be sure to properly cut and install the plastic channel inserts (underside) or you will experience an annoying whistling sound. If you're looking for high quality crossbars, I highly recommend these.


The rack legs and cross bars were shipped immediately and arrived 3 days ahead of the expected delivery date. I was impressed with the ease of assembly and installation. The installation videos on the web site were very helpful. The rack is fitted perfectly to my vehicle and it blends nicely with the black trim on my roof rails. I am very pleased with the equipment and the price was actually about $50 below a similar rack assembly from a well known competitor. Chelsea D, who took my order over the phone, was very helpful and made the process very simple. Thanks for exceeding my expectations.


Easy to install on the Bronco Sport factory roof rails allowing for a very low install height for the Pioneer platform!


The crossbars & side rails were fairly easy to install especially after watching the etrailer videos & with a little help from my husband. I use them on my KIA Seltos to carry a kayak. So far they have performed well.


I am very pleased with the Easy to navigate website and expedited shipping for no extra cost. I ordered and received my product in about a week, which is very reasonable for being across the country.

The product arrived in tact and with no damage. Easy to put the rack bars on my jeep. I've included pictures of the completed result. We plan on buying the attachments that will mount our bikes and when we do we will be doing so from etrailer.


I did a lot of research on this product and others like it and even went to far as to buy a set from a different maker off of [online vendor] because it was far more inexpensive. They (Legs\Crossbar Combo)didn't work for my accessory (Thule Upride), so back the went.

I took the plunge and bought these paired with the Vortex Aero Crossbars and I cannot be more pleased. Rock solid, and they have to be when you have a $3500 bike on top of your vehicle. They don't make much noise and are very easy to install\uninstall as needed. I've used them solidly for a year now without a single issue!

I wholeheartedly recommend these legs and crossbars to anyone on the market.


I spent a week reading reviews and forums to find the right one for my 2019 Jeep Cherokee that I just bought a few weeks ago. I just have to overthink everything but it paid off. I just received them this morning and installed them myself! First time for everything! It was really easy. The only part that was frustrating was the very first part... sliding the rubber pieces into the crossbars. They would not slide very well so I ended up using a bit of oil to make them slide better. Other than that, installation was easy and quick. I LOVE the looks of them. Very gorgeous!!! Thank you so much!! Very happy with the end result!!


These feet worked like a charm! We were able to use these to install the Rhino Pioneer Rack onto our existing factory rack (2007 Toyota Land Cruiser). Adam at was awesome!


Nice, solid rack. It went together very easily. It will support my canoe and my rod rack fits well on it. It’s very light weight and the directions were spot on. There is also videos to help make installation easy.


The entire kit was extremely easy to install and Jaquan B. at eTrailer was very helpful. The Rhino-Rack crossbars look great and are sturdy.


Absolute best customer service experience. My vehicle was brand new to market. Customer service was attentive, accepted photos of the factory vehicle rails, then quickly recommended the compatible crossbar options and updated vehicle compatibility on the website.


Easy install!


They fit perfectly and as described, had no issues whatsoever. Whole rack system installed easily in an hour with all needed tools being supplied. They also work well with the kayak racks I had purchased prior to these.


The Rhino rack system we bought and installed has worked perfectly on our Subaru Crosstrek. We purchased it to hold a rooftop tent and it was easy to install, incredibly sturdy, and noiseless with or without the tent.


The one star rating is due to having to wait for a human customer service person to pick up the phone and advise.When I pushed the button to "place an order" I was attended to quickly. Here's the problem..The rack is SOOO SUPER noisy!! It whistles like a sailor. I was told "sorry, they are noisy, and you can buy something that will help with it from the manufacturer. I said I'd send it back, and agent "Lori" reported once it's been installed there are no returns. Too bad there wasn't an amicable resolution.
