Video Transcript for Rhino Rack Roof Rack Review - 2016 Acura MDX

Today on our 2016 Acura MDX we'll be doing a test fit of the Rhino-Rack Vortex Aero Crossbar System, using part numbers RRVA137B-2 for the 54" Black Aluminum Crossbars, and then part number RRRLKVA for the 2500 Series Leg Kits, and then part number DK400 for the clamps and the pads. We've already got the front one installed as you can see here. We followed our instructions, we came from the door jam over to the center, we measured out the distance and how far we're supposed to be for our legs underneath the bars, and then we tightened everything up, and we got it. So let's go ahead and do the rear one together. First thing we'll do is we'll grab the leg first, and then our pad. We want to make sure that the arrow is pointing out, so away, and then we're going to push that on the bottom. Make sure that it seats all the way around.

Once we've got it seated let's go ahead and remove our bolt here. We'll grab our clamp. Now you need to make sure that you have the correct clamp because they differ from the back and the front. We don't need to tighten this down all the way. Just need to get the bolt started so it's loosely installed, and then we can turn our crossbar over. Now when you get your kit it's going to come with a scale that gets inserted through here.

When you follow your instructions it's going to give you a number to set your leg. For demonstration purposes we're just going to be using our little tape measure here. We're going to measure this direction here. We'll measure it out and we'll set that. First we'll need to remove the end cap and we're going to slide this on here.

All right, once we get it on there then we can take our tape, set it to where it's supposed to be, and once we have that set we can take our included tool and tighten that down. One we've got that tight we'll replace our end cap and we can actually use the rest of the strip that we have to fill in the gap on the other side. All right. Once we have that done we can open up the rear doors of our MDX and set our crossbar in place. Now in some cases it's not a bad idea to get an extra set of hands, but you'll want to set it down gently in the roundabout area. Now according to our manufacturer's instruction we need to have 29 centimeters ...

Excuse me, that'd be 75 centimeters from center to center. Once we get that lined up let's go ahead and check the other side. Almost got it there. All right. That looks pretty good. All right then, we can grab our included tool. Now a few things you want to look out for, you want to make sure that your clamp is going to go underneath your door here, and that your pad is actually seated on top of the roof. Once you've ensured that that is the case you can then tighten it down. Now you want to be sure and tighten them down evenly on both sides, so we'll go ahead and seat that clamp right there and then we'll run over to the other side and do the same thing. Now that we know that they are both seated correctly we can just kind of keep an eye on it and then tighten them both down evenly. This side actually looks pretty good. We'll finish up on the other side. Now the included tool actually has a built-in torque mechanism, and that's actually this blue portion here. You tighten it up until that runs straight, and that's how you know that you've got it. All right, now the only thing left to do is to put on our caps, lock them up. You of course want to make sure and set it in correctly. We can also lock up our end caps of our crossbar. With the included tool lock those up so we know they're in place. Then we're ready to load up our favorite Rhino-Rack accessory and hit the road. Well that's going to complete our test fit of the Rhino-Rack Vortex Aero Crossbars Roof Rack System on our 2016 Acura MDX.

Average Customer Rating:  4.7 out of 5 stars   (2257 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.


It works well. Good value. Not the fault of trailer or Rhino, but if you are vertically challenged, own an suv, and lugging 50+ pound kayaks then any roof top system needs to be researched thoroughly. I’m happy with this product. My wife could use some help.

2016 Acura MDX

This is Thai Khuu ,Thanks I got packaged ,and I already installed, It just take about 1 and 1/2 hour,but I just take time to do carefully,so it is took me 2 hours, It is great ,me and my wife like it,and I my order the other package exactly like this for my second acura mdx 2016, I enclosed the pictures installed roof rack , Thanks


The Rhino Vortex roof rack is great - As someone that leases SUV's, it's more economical to transfer a fully paid for roof rack rather than purchasing a factory installed model!

Still enjoyment roof rack - I’ve used it on three different SUVs!
Mjs - 12/19/2020


Good product, great service!


Parts fit exactly for my vehicle and instructions were easy to comprehend. Follow them step by step, and should have them on the vehicle within an hour. Going to haul two kayaks after attaching Malone SeaWings.


Solid product, very sturdy.


Great product, it's been over a year and still holding up well on my MDX.


Everything worked out great!


This roof rack system has been wonderful. I wish I had bought it sooner! The install was easy (I am good with tools and I am an engineer for comparison) with full step by step instructions. The fit is perfect and solid. It’s been great for Paddleboards and also my roof top carrier.

Acura MDX

Got a MDX A-Spec and didn't want to put on the factory side rails and cross bars because it diminishes the sporty look. This rhino rack is a great solution for me because i can put these cross bars on for the top box and bike rack but can easily take it off to get back to the original sleek look. I'm happy with the product. Solid construction. I'm confident this will hold the load well without harming the car. I'm looking forward to using my original box top and my new bike racks. Also, thrilled that i can use this rack on my volvo too just by getting the volvo clamps. Great service from Michelle S. She answered all my questions and got me in the right products. Delivery was FAST. My only suggestion/improvement: the installation instructions. Had to read them a few time to 'get it'. It seemed overwhelming initially but the installation was pretty straight forward.


Quality product and great customer serv ice!



Product worked well. Installing was a little tricky but video helped a lot.


I couldn't be more pleased with the overall experience. The website, checkout, shipping, packaging and product were all a 5.... Thanks!



Easy to install. Great product and serv ice.







Review from a similar DK in Roof Rack

Installed this and 65" Vortex Areo crossbars on a 2015 RAM 5500 chassis cab/crew cab. It is listed to fit 1500 to 3500 RAM's and neither Rhino-Rack or etrailer would confirm it would fit the 5500. My research suggested there was not much, if any difference, between the 3500 and 5500 crew cab, so ordered it any way. Installation was relatively easy, fit seemed to be good and have made multiple 200-300 mile trips with a 75lb kayak. Good price, great customer service and fast delivery through etrailer.

Neither Rhino-Rack nor have tested the roof rack on a 5500 ChassisCab, which is why we couldnt confirm the fit.

Review from a similar DK in Roof Rack

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.


Review from a similar DK in Roof Rack

Fairly easy installation. Read the instructions thoroughly before hand and get familiar with the parts. Take care when installing mounting studs onto car itself so as not to strip or cross thread them. Once installed they look great.

Fantastic! Very little noise on highway and sturdy.

Review from a similar DK in Roof Rack

I've had this Rhino Rack 2500 series for one year. I've outfitted the rack with one "J hook" style kayak holder and one "cradle" kayak holder. I am able to securely travel with two kayaks on the roof of my 2014 Honda Civic sedan without issue. During the one year I've had this rack I've traveled over 1,000 miles with two 12 foot+ kayaks on my roof. I can set cruise control at 70mph and not worry about the rack failing. I rate it four (4) stars because the cradles will sometimes move during a long drive and have to be readjusted. This is something that is more cosmetic in the since it looks slightly off, however it does not affect the racks security.

  • Rhino Rack Recommendation for a 2016 Acura MDX
    For your 2016 Acura MDX with a naked roof the Rhino Rack roof rack part # RRVA137B-2, # RRRLKVA, and # DK400 has been confirmed as a fit and would work great if you want an aero bar rack.

  • Will the Rhino-Rack 2500 Roof Rack Fit a 2018 Acura MDX
    The Rhino-Rack Aero Bars # RRVA137B-2 are compatible with your 2018 Acura MDX when used with the 2500 Series Legs # RRRLKVA, and the DK Fit Kit # DK400. We don't have any shops that we partner with, but with that being said I am confident that you can install it on your own as it is actually pretty easy. I have attached an installation video of us putting the same roof rack on a 2016 MDX as well as the instructions for the roof rack for you to check out. If you let me know what you will...

  • Rhino-Rack Roof Rack Fit on 2017 Acura MDX
    We can get your 2017 Acura MDX with a naked roof set up with a roof rack, though I recommend going a different route than the HD bars you asked about. The reason for that is these are uniquely large square bars, much larger than standard square crossbars, and don't offer additional capacity. Going with an aero roof rack from Rhino-Rack will still give you the same 165 lb dynamic capacity, will be much quieter, and allow you to use the rack for other things if you'd like. The HD bars often...

  • Sound Difference Between Rhino Rack Square and Aero Bar Roof Rack for 2019 Acura MDX
    There's a significant wind noise difference between the square bars and the aero shaped bars. So for your 2019 Acura MDX you'd have to decide between saving some money and going with the square bar Rhino Rack roof rack part numbers # DS1375B and # DK400 or if you value the quieter option of the aero bar Vortex rack part # RRVA137B-2, # RRRLKVA, and # DK400. The install and removal of these racks is pretty simple but it wouldn't be so simple that you'd want to take it off and on several...

  • Will Thule Aero Crossbars Work On a 2015 Acura MDX with Bare Roof
    I do have roof rack options for a 2015 Acura MDX but Thule does not offer any for bare roof models and since you can't mix and match crossbars and feet from a different brand you won't be able to use Thule crossbars. Instead, I recommend the Rhino-Rack Vortex Aero Crossbar System part # RRVA137B-2, part # RRRLKVA, and part # DK400. This system has aero shaped crossbars and is very cost effective when compared to other like options.

  • Roof Rack Recommendation for a 2020 Acura MDX with a Naked Roof
    To install a roof rack on your 2020 Acura MDX we're going to need to get all new parts as Thule doesn't have a fit for your MDX with a naked roof. Because of this I recommend checking out the Rhino-Rack Vortex roof rack which uses the following parts: 54" Vortex Crossbars - # RRVA137B-2 2500 Series Legs - # RRRLKVA Fit Kit - # DK400 This will be a little quality upgrade in you roof rack as well since this uses the aero-style bars which not only look better, but they also have less wind...

  • Can 18 Cubic Foot Cargo Box Install on 2016 Acura MDX with Rhino Roof Rack
    For your 2016 Acura MDX with the Rhino Rack roof rack part numbers # RRVA137B-2, # RRRLKVA, and # DK400 installed you could pretty easily carry a larger 18 cubic foot cargo box but you would just need to be sure to stay under the weight capacity of the roof rack (165 lbs), and the roof capacity of your vehicle that is listed in the owners manual. The Sportrack Vista XL part # SR7018 would fit the crossbar spread of your roof rack and would work well. I attached a review video for this...

  • Roof Rack for 2017 MDX with Naked Roof for Carrying 2 Kayaks
    I would go with an aftermarket roof rack for your 2017 Acura MDX as it's going to cost considerably less and be just as good if not better. For the money and the quality the Rhino Rack # RRVA137B-2, # RRRLKVA, and # DK400 is the best option. It gives you an aero bar roof rack that's very high quality at a price that beats the higher end rack manufacturers. The INNO kayak carrier part # INA450 then would be a great choice as it can carry up to 2 kayaks like what you need.

  • Motorcycle and Bike Rack Solution for 2015 Acura MDX
    Your best option would be to go with a hitch mounted motorcycle carrier for the scooter like the Ultra Fab part # UF48-979033 and then a roof rack solution for the road bike as there isn't a way to carry both a scooter and road bike on a single hitch rack. Then for a roof bike rack we have the Thule UpRide part # TH599000 which will work well as long as you have a roof rack installed on it. If you don't have crossbars that go from left to right you'd also need a roof rack like the Rhino...

    We do have a large selection of roof racks available that are confirmed to fit your 2014 Acura MDX with the naked roof. When it comes to roof rack systems, the difference in brands/manufacturers will usually just come down to personal preference, along with the type of crossbars you want.

This won't help with the noise, but will give you a better place to tie down your bag to keep the water out. This hitch will work # e98840 and you can use it with this carrier # e98874 if you wanted to go that route. The hitch will work with this rack too # Y02458. I would suggest getting the roof rack...

If your MDX has the flush mounted roof rails that run front to back I highly recommend Thule WingBar Evo Roof Rack System that uses 53" Thule WingBar Evo Crossbars # TH711420, Rapid Podium Feet for Thule Crossbars # TH460R, and Fit Kit # THKIT3132.

    From the sound of your question, you are looking to mount the Curt Roof Mounted Cargo Basket # C18115-117 directly to your roof with the Custom DK Fit Kit # DK400. However, the # DK400 fit kit only fits Rhino-Rack 2500 Series Legs # RRRLKVA along with the Vortex Aero Crossbars # RRVA137B-2. This setup is designed to fit your 2014 Acura MDX if you have a bare roof. The Curt Basket is not compatible with this rack because the clamps do not fit around the 3-1/8 inch wide bars.

You will additionally need Rhino-Rack # RRRLKVA Legs, and # DK400 Custom Fit Kit.
