Video Transcript for Step-By-Step Installation Tutorial for the Rhino-Rack Vortex Roof Rack on a 2023 Toyota Highlander

Hi Matt with etrailer and today we're gonna be talk about the Rhino-Rack Vortex Aero Roof Rack System on the 2023 Toyota Highlander. Now this is gonna be a great option if you're kind of running outta space in the back of your vehicle and you need to put some additional accessories up top to kind of store some extra luggage. It's also gonna be great if you're going out camping and you need to put your additional camping gear up top as well. Our roof rack system's gonna have three components. The first one's gonna be our 49 inch arrow crossbars, that's gonna plug into our Rhino-Rack Towers and that's gonna sit on to our base. This is gonna have the capacity to hold up to 165 pounds but I'd always recommend checking what your vehicle can withstand for its roof as well.

And taking a closer look at that crossbar, this's gonna be in the shape of an arrow so this is gonna be tapered on both ends to reduce wind noise. We're also gonna have this vortex strip up top that kind of peels off and can be trimmed and we're gonna have one on the bottom as well that has a measuring strip on it. Now in our case today we don't have a measuring strip on the bottom since we keep this one in the shop, we use it a lot so we're just taking it off. Something to note, we can clamp accessories on here but if you don't want to clamp anything on you can actually peel this vortex strip off and place your accessories on this T track up here. And at the end of our crossbar we're gonna have this spot here and that's gonna be a lock so no one can come by and kind of take off any accessories you have up here.

But you can actually get this switched out and put a metal lock core that kind of matches the one down here so it's keyed alike. We can actually just remove that with our key here, this fit, kind of matching what it says here with the unlock symbol and then take it off real easy. That's gonna reveal this bolt that plugs into our base. That base is just gonna sit here, so everything's one unit. What I do like about these bases are the way these sit on our rails, can be very flush and fit very nice.

And even the back one kind of raises up a little bit differently just so our crossbars are level. Now, they are gonna be fixed at about 32 inches. So that is one of the downsides with it being fixed that it's only gonna be able to accommodate certain types of gears. But on the plus side, since they are fixed they're gonna be a lot easier to install. As for how it's gonna sit on the top of your Highlander, we're gonna get maybe just a little bit of overhang on the sides so it sits very flush with the vehicle.

If you'd like the low profile look of it this is a pretty good fit for the Highlander. For how far it's gonna sit up from the top of your roof, from the bottom of the crossbar to the top of the roof it's gonna be about two and a half inches. So that's pretty close to your roof but definitely still enough room to get a clamped accessory on there. And from the top of the roof to the top of the crossbar, it's gonna be about four inches. So that's something to factor in when you're adding gear to the top of your system, just adding that four inches plus the height of your vehicle plus the height of the gear to the system. So if you want to keep these on your roof for an extended of time, they're gonna be able to stand up to the test of time since they are made of a durable aluminum with a black powder coat finish. So that's just gonna help 'em stand up to weather conditions and less prone to rusting. And actually where they sit now is great because if you wanna leave them up all season long they're not gonna really interfere with your sunroof so they're gonna be far enough back where they sit in a very nice location. As for the installation process I thought it was pretty straightforward, especially with it being on fixed points, it makes it a lot easier. Really my biggest issue with it was just trying to tighten the crossbar down to the tower. It can be kind of difficult to reach underneath here and line everything up. We found a couple workarounds around that and if you're kind of getting snagged up on that too just stick around and we'll show you how to do it. The first thing you're gonna want to do is lay everything out. So we're gonna have our 49 inch crossbar, we're gonna have our bases and over here we're gonna have our towers, the hardware that goes with them and we're gonna have our included tools right over here and to additional keys and a tool for your crossbar. And what I recommend bringing as well, we're gonna recommend using a screwdriver, a 10 millimeter socket and wrench, a tape measure and some trim tools. And next up we're gonna move on to putting our bases on our roof. Before we can put our bases up there, we're gonna have to remove this piece that attaches to your rail and instead of using a screwdriver with some tape on the end we're gonna tape our rails so we don't damage it. We find it a little bit more helpful in this way rather than the screwdriver method. So I'm gonna just take my trim tool and I'm gonna stick it underneath that piece that sits there and I'm gonna try to push against these tabs and push up. It should start to kind of pry a little bit. And once I get one side up, I like to kind of move over to the other side, push that a little bit more up too and come back and finish the job just like that. You'll notice we only have two bases down here and that's just because we've already installed the back crossbar. And now we're gonna have our front right and our front left. We're gonna start by installing our front right now. To get that base up there, I'm just gonna make sure this hole here is lined up with this one here and I'm just gonna set it down. You'll notice we're gonna have the fatter side on the outside and the thinner side on the inside. Next up, I'm gonna take this bolt here, measure an Allen key and just kind of set it in there. Just hand thread it a little bit, make sure it's lined up right and now just take our included tool and tighten it down the rest of the way. And after when you've completed this on this side you can do the same thing on the other side. Now I'm gonna come over to our crossbar and I'm gonna flip it over so that the bottom's facing up and I'm gonna use the included tool that's specifically for our crossbar to remove the end cap. All you have to do is turn and twist and pull it off. And now I'm gonna just take our towers, making sure that middle block is facing down and I'm just gonna slide it through our channel at the bottom, just push it down some and I'll put our end cap on it real quick. Just gonna grab our included tool and tighten it down just somewhat, just enough where you can move it some but it's not gonna slide around very easy like that. And just do the same thing on the other side. Once everything secured on here you can lift it up and put it on your roof. You might need an extra pair of hands if you can't reach out that high. But once you get it up there, you just got the line up the back one so it fits into those tabs just like that. And you can let the other side drop and you might have to adjust it some. That's part of the reason why we didn't tighten it all the way. But once you have it where you need it to be then you can tighten it down the rest of the way. To tighten it down the rest of the way you can use our tool and just kind of come over underneath here and try to line it up. I find this a little bit difficult to try to do just 'cause it's kind of hard to find that hole and line everything up. So what I like to do is actually just remove our crossbars and since they've been tightened earlier not to slide around, we can actually do it on a flat surface on a table and just tighten 'em down that way. And when you have it tightened enough you can repeat the same process on the other side. Once everything's nice and tight and it's not gonna move around, you can lay it back up there and fit it back in to its spot just like so. And now we can tighten our towers to our bases. And to do that is pretty easy. All you have to do is take your included key and use it to take off your end cap just like so. You can put this off to the side and taking your bolts and washers, you can kind of just thread this through this hole here. What I like to do a lot of times too is put the bolt through beforehand just to make sure there's no, nothing in the threads like some of the black powder coat that can make it kind of harder to thread in. And once I've got it tightened down enough, I can use a socket and a wrench just to tighten it down the rest of the way. And once it's about tight enough for you, then you can put the end cap back on and repeat the process on the other side. Once everything's nice and tight and secure, just do a quick kinda shake test to make sure everything does fit right and after that you should be ready to hit the road. Overall I think this is a great option for the Highlander. I think it fits really low profile and it sits pretty flush with our vehicle and it makes for a pretty easy install. Now there is a few kind of like spots where it's a little bit difficult to maneuver especially trying to get underneath here and tighten that crossbar to your tower. But overall, I still really think this is a great fit for the Highlander. But if you've liked everything you've seen today that was just a look at that Rhino-Rack Roof Rack System on the 2023 Toyota Highlander.

Great service and great it!!

While the fit is excellent on these feet, and the finish seemed good to start, after 2 years they have corroded and bubbled underneath the black coating. For the price, I expect them to last without corroding/finish failing for longer than that.

Working great to mount my crossbars and kayak rack.
by:
Installed on a 2025 Honda CRV with vortex aero bars that I used to have on another car. Feels solid enough to lift the car with. I love this rack.

Note that eTrailer (or Rhino Rack, not sure) recommends spacer blocks for the rear bar on CRVs, to lift it a little higher and make the rack more level front-to-back. Otherwise there's a bit of a slope to a canoe or kayak due to the slope of the roof profile. The Honda factory bars don't adjust for this and they carry my boat just fine (other than being kind of wimpy), so I don't think the spacers are needed for the Rhino Rack, either. Maybe just for aesthetics. I did not buy them.

After a year, still happy about this.

by:
We had been shopping around for roof options for our new 2022 grand Cherokee, when we came across this. For us, the OEM mopar crossbars were ugly - extend about 6 inches from the roof. These are very low profile, and insanely sturdy. Additionally, installation is crazy simple.

The only recommendation we have that differs from the instructions - we used the rear set of mounting holes on the factory rails. Using the front set of holes as recommended by the instructions for cross bars meant that ski racks would be too close together, and the ski bindings would not fit. Other than that, very satisfied!
by:
These Rhino-Rack products are solid. Installation was quite simple. It took me no more than 2 hours from taking off the OEM rails to getting the crossbars to tighten down.

Keep in mind that these legs were designed for the Toyota Prado (it even says so on the installation guide). Once you remove the Lexus OEM rails, you will notice a groove, about 3/4" deep and 1-1/8" wide, alongside the roof. If your GX does not come with the OEM rails, the grooves might already be covered up by the factory drip trim pieces (Toyota PN 75557-60050, 75555-60030). This Rhino rack kit does not come with any hardware to cover up the grooves. I was told they would not cause any leaks because the mounting points are tightly sealed.

But if you have severe OCD like me, those grooves will be bothering you (even though you can't see them). Instead of paying over $xxx for the OEM trims pieces. Fill them up with some 3/4"wide 3/8 inch thick insulation tape, then tape a strip of 1" wide, 1/8" thick neoprene rubber strip on top. The end product looks just like OEM. I hope my simple idea will help other fellow OCD survivors.
by:
Everything came promptly, no issues. Everything fit and the videos from eTrailer are a great help!
by:
I searched a lot of websites before finding what I needed on etrailer.com for my 2012 Suzuki GV. I was looking for the proper mounts to install a Kayak rack system. Because my vehicle has a built in rail system it was very confusing what was needed. Thank you etrailer for hooking me up with the appropriate parts for the Rhino system, it worked great!
by:
Great item, pretty easy to install. I posted a longer review for the full setup on our 2019 Highlander with 2 biggish kayaks under reviews for the rack pillars, Item: RRRCL4. When fully tied down, we used hood loops front and rear for both boats.

Great service from Carol C.

Love etrailer. They always have anything and everything you need and always at a great price. Also great videos and tutorials to help with your DIY install! Salvaged my old Rhino Aerobars with a new Rhino roof kit from etrailer for my Bolt.
by:
Well made parts, shipped quickly. I was able to install the rack with no problems by following the instructions. Good choice if you want a quality roof rack for $xxx less than a comparable Thule or Yakima.

Price, Quality, communication, Shipping Speed. Everything about this is excellent!

Fitment is good, did not come with security capscrews even it included a security wrench. The rack can be removed with allen wrench.
When rack is in place, I cannot use the sunroof on 2023 Buick Enclave.
Otherwise, it works fine!

Looks amazing, and was super easy to install.

Product arrived earlier than expected with all parts. A little work to install but everything fits perfectly. After I dry fit the parts and then tightened the sliders to the cross bars I attached the rack to the mounting brackets on the roof using a 10mm wrench. It was easier access than trying to use the allen head wrench. It's on with a solid fit and I love it.

Very well but takes a 15 minutes to take on and off.

by:
Two stars because the provided hardware interferes with the factory rails when using the provided cover plates (to be installed when you remove the cross bars & towers). Had to source my own 12mm long cap screws because provided 16mm were too long. Otherwise works as advertised.

I reached out to the manufacturer and it was the first time that they had heard of this being reported.

by:
I purchased the Rhino Rack roof rack as an alternative to the factory installed products and the more popular Thule and Yakima brands. The Rhino Rack is solid and sleek and is largely silent while driving (if I have the roof open you can hear a soft whistle). Not only does the rack look fantastic, but the non-slip top and the strong bars make carrying things on top a real pleasure.
by:
Toyota RAV4
The Rhino rack for my Rav4 hybrid fit perfectly and has been used extensively for carrying whitewater and touring kayaks since installing it one year ago.

etrailer videos were helpful while I shopped for alternatives to Thule and Yakima which did not offer the specific feet I needed to install their racks.
by:
Update to my review: etrailer sent additional strips to set into the gaps on the bottom side of the rails and there is no longer any whistling, so I've rerated my purchase to Excellent. I'm not sure if the strips for the bottom side (the side that faces the roof of the car) should have come with my rails to begin with or if they need to be purchased separately (etrailer sent them to me at no charge after my initial review). Covering those gaps with duct tape will also do the trick.
by:
Custom RCP Fit Kit was perfect for my 2018 Chevy Bolt. Screws fit perfectly in the predrilled holes on the Bolt's pVery solid and holds my 80 lb tandem kayak mounted upside down on my rhino rack cross bars with 2 tie down straps over the kayak, and a front strap attached to a loop strap held in pace by the hood. I attached the rear strap to my bike rack trailer hitch. Maiden voyage this past weekend to a spring run 45 minutes from home. Kayak didn't even budge an inch. Rubber on the surface of my rhino racks prevented any slippage.
