Video Transcript for Rhino Rack Roof Rack Review - 2018 Ford F-150

Speaker 1: Today on our 2018 Ford F150 we'll be taking a look at and showing you how to install the Rhino Rack Roof Rack System. This is going to consist of the Rhino Rack Vortex Arrow Crossbars, part number RRVA150B-2, the Rhino Rack 2500 Series Legs, part number RRRLKVA, and the Fit Kit for our F150, part number DK427. Now, keep in mind that our crossbars are also available in silver with part number RRVA150S-2The Rhino Rack Roof Rack System gives us an opportunity to carry more gear inside our truck bed as well as on our roof, whether those are bike racks, ski and snowboard carriers, or kayak carriers. The aerodynamic shape of our crossbars is going to help to reduce wind noise and drag. On our crossbar end cap you'll see we have this plastic lock core here. This does lock, but you can replace those with metal lock cores, which will add more safety and security.

We'll remove that, and you'll see our weather strip here on the inside. This can be removed and cut down, and replaced with channel mounted accessories.The leg kit of our roof rack system comes with a metal lock core, which is going to help prevent theft and tampering of your roof rack system altogether. Our Rhino Rack Fit Kit is going to be custom cut and made for our vehicle to give us a nice, secure fit. Any portion that touches our vehicle is going to have a rubber coating to prevent any scratches or abrasions. The Rhino Rack Roof Rack System has a 165 pound weight capacity, though you do want to double check your vehicle's owner's manual to make sure your roof can withstand that much weight.

It's also going to come with a limited lifetime warranty, and be easy to install. We'll show you how to do that now.Everything that you see on our table is what we will need to install our roof rack system. We already have our front bar and half of our back bar installed, but we'll show you how to do the other half. We're going to provide our own flat tape measure, but everything else will be included. We've got our crossbar here, the end cap for our crossbar with the included key.

We'll have our leg kit with the included key to lock down our end caps. We've got each piece of our fit kit; the pad, and the clamp, and then our included tool to tighten everything down.We're going to start by removing our bolt here on our leg. Take our clamp, we're going to replace it over the top, and we'll tighten down our bolt to hold our clamp into place. We want to tighten this down just enough so that it holds our clamp. We don't want it too tight, because that can mess up putting it onto our roof.

With that tightened down, we can remove the bottom piece. We'll take the rubber pad here on the bottom, and we're just going to squeeze that together. Once that's all together, we can place it back onto our leg.With our leg kit assembled, we'll place this onto our crossbar. Now we'll measure out our placement for our leg kit. It's going to be about 16.6 centimeters. That measurement will be in your instructions, and we're just going to take our included tool and tighten down our bolt here. That's going to hold our leg kit in place. To finish off the assembly, we'll place on our end cap and lock them into place.Now we're ready to open up our vehicle doors and load up our crossbar. We'll gently place it on the roof of our vehicle. We want to make sure that the hook goes around our door. Now we can measure from the inside doorjam to the middle of our clamp. That's going to be 52 centimeters. This will give us our placement for our crossbar. We'll do the same thing to the other side.Now we'll tighten down our bolt here using our included tool. We want start so that it sits just up against our door frame. We'll do the same thing to the other side. Now, we want to tighten our bolt down until the skinner portion of our torque tool is completely straight, just like you see there. We'll finish off by placing on our end cap for our foot pack. Now that we have our roof rack system completely tightened down, we're ready to load up our accessories and hit the road. That's going to be our completed look at the Rhino Rack Roof Rack System on our 2018 Ford F150.

Average Customer Rating:  4.7 out of 5 stars   (2628 Customer Reviews)

This custom fit kit lets you mount 4 Rhino-Rack 2500 legs to your vehicle with a naked roof. Clamps mount to legs with bolts. Includes 4 clamps and 4 pads.


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.

2023 Chevrolet Silverado 2500

I needed roof racks on my 2023 Silverado to accommodate the shape of my canoe. I had Yakima racks on the camper shell but the canoe was hitting the top of my truck. My Rhino racks showed up yesterday evening and I’m ready to go this morning!


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.


Great packaging, timely delivery and good quality Rhino products! I watched a utube video on installing the rack system which made the install much easier.


I just finished the install of the Rhino Rack 2500 with the Vortex Bars. It looks fantastic on my 2020 Silverado. It's solid and very well built. I'm a surfcaster on Long Island and I use 1 piece fishing rods up to 11ft long so the easiest and best way to transport them is on top of my vehicle. I selected this rack because it's aerodynamic and with the accessory channel I was able to easily attach them by sliding a 1inch stainless bolt and stainless washer in the channel. This hides the attachment and makes it impossible to remove unless you have the keys to access my rod rack which has a padlock.


I've had Thule & Yakima products over the years, with no issues. But I'm really glad I ordered this set-up for my 2021 F-150. I think you get just as good of a product from Rhino, maybe even better, for a slightly lower price. Everything feels sturdy and well made (with the possible exception of the locking covers, which feel a bit flimsy). I really like this set-up, and the precise measurements and guides made for a perfect snug fit. The rubber strip running on the upper long edge of the bars feels like it will definately help keep accessories from sliding out of place.

2017 Ram 2500

Fits 2017+ Super Duty!

I had the
vortex 2500 on my previous truck which I removed when I traded it in for the 2017 super duty. I knew all I needed was the foot kit to make the switch over to the new truck. But, for some reason Rhino rack didn’t have a kit for the new body super duty. They did however have kits for the 2015+ F150 which I knew would work because they share the same cab. My hunch was correct and the foot kit worked great.
The measurement for the spacing between the feet were a little off. The F150 calls for 169mm and 166mm between feet (front bar/rear bar). I found that to be a bit too narrow. I added about 5mm on each and it fit perfectly.


Great product, very well built, heavy duty. the assembly and settings instructions are easy to follow and when I placed it on the roof of my 2015 f150 super cab, it fit perfectly with no further adjustments necessary. I am very impressed with this Rhino Rack and feel it will probably outlast me and be handed down through many generations. Also purchasing from etrailer was an awesome experience, fast free shipping. easy website to navigate.


Thick rack came on time as promised. I was notified when my rack was shipped and a link to to the carrier was attached Rack was easy to install and fit my truck perfectly. etrailer was a pleasure to do business with.


Fast shipping and correct products described on the website, I love ordering from etrailer.


The rhino rack assembled easily, fit the channels in my roof perfectly and looks great! 5 stars for on time delivery, good packaging, super easy ordering also. Very happy customer!


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.


I have a 2020 Chevy HD crew cab. Fit perfect. Installation was easy.

2021 Jayco Precept Motorhome

High quality components that are very easy to install yourself.



This rack is rock solid and has held up flawlessly. The finish has not weathered or faded at all - impressive quality. All of that, plus it was easy to install.

@Drew We're glad to hear that! We're glad your Rhino-Rack roof rack is still working well for you.


Ez to follow instructions and quick ins tallation.


I’m very happy with the quality of the rack and the fit is perfect. Assembly instructions could be better.


Everything arrived amazingly fast and install was a breeze. Super happy with the finished product and will definitely be shopping at etrailer in the future!

2018 Ford F-150

Fits my truck perfectly, looks really good, and was a great deal less expensive than the bigger name brands you probably know about. The customer service was fantastic and the installation video they supplied was customized to my specific truck and rack kit making it a breeze to put on the roof.


I have to admit that I was a bit hesitant to go with a rack brand I never heard of as opposed to the “Y” or “T” brand. Those concerns soon disappeared as I assembled and mounted the Rhino Roof Rack onto my 2020 GMC 1500 Denali.

As an engineer, I appreciate engineering attention to details:

- the fit to my vehicle was accurate to +/- 1mm
- the hold done bolts are theft deterrent
- the mounting towers include locks
- placement of the mounting towers is mistake proof with integrated measuring system
- all of the surfaces that may whistle in the wind are closed
- the end caps are held in place with a unique latching mechanism
- even stickers are provided to allow you to remove and replace the racks without error

Rhino Rack ... your engineers and product execution team are #1 in the business!!!


Well I should get a dummy award for this product, I was convinced that I had the wrong part but etrailer customer support is the best. First they are knowledgeable and quickly realized they were dealing with an uninformed customer, 2nd they are patient and walked me through the process of how to correctly install the pads, & 3rd they laughed right along with me. This was the correct product for my truck and fit perfectly once I attached them properly. Can't say enough good things about your customer support. Thanks.


The racks look great and are solidly anchored.
have yet to use them under load but I am pleased with the final product so far.

My only complaint was that the assembly process is difficult to understand unless you Google the help videos. The assembly process is confusing and tedious until you gain an understanding of the overall setup.


So helpful! Bought a roof rack back in 2019 and have since bought a new vehicle. The roof rack was no longer compatible and I lost some of the parts in a move. I called customer service and they helped find a solution so that I could use them on my truck. Super helpful and super friendly! Product worked great and I can still continue to use my roof rack instead of buying a whole other one. Thank you!

2015 Ford F-150

Bought the 2500 Vortex kit for my 2015 F150. Very well made kit. Installation was a breeze. Just follow the directions and you can not mess it up.


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.
