Video Transcript for Yakima Roof Rack Review - 2016 Honda Pilot

Speaker 1: Today in our 2016 Honda Pilot, we're going to be test fitting the Yakima Round Bar Roof Rack System consisting of part numbers Y00409, these are the round crossbars on the top here, and these are 58 inches long.We'll also be using part number Y03536, and this is the Round Bar Adapter Kit for the Yakima towers.We'll also be using part number Y00146. These are the Baseline Towers designed for naked roofs.Finally, to attach it to the vehicle, we're using the Base Clip Fit Kit part number Y06152.This is going to be the same for the rear bars as well. These are great sturdy cross bars for your roof, and car carry a wide variety of accessories such as bike racks, cargo carriers, excuse me, cargo baskets, and cargo boxes.While, they are exceptionally sturdy, they do cause noise while you drive. Now, you can purchase fairings that you can find on to help cut down that wind noise and drag, or you can upgrade to the Yakima core bars that also utilize this tower system.Moving onto the towers themselves, at the end caps here, we do have these plastic portions that can be removed and replaced with the Yakima SKS Lock Core System, so you can secure it to your vehicle and make it key to like with the accessories that you're hauling.Removing our end cap here you can see how everything attaches to the vehicle itself. We have the clamp that attaches to the door frame, as well as the pad underneath. So, your vehicle isn't going to get damaged or scratched once this is installed, because the clamp is also padded once it's being installed.So, let's go ahead and show you how the rear bar gets put into place.

We already have it partially assembled on our lovely table over here, With all the parts that you need right in front of it. So, our first step is, we're going to take our adapter kit for the round bar and attach it to our tower.This is a very easy process. You simply take the plastic portion here, push it in on the top, you're going to hear a little bit of a click. We'll take our round bar adapter, attach it to the screw in the center. We'll pull out this tab here, so we can get to the screw, flip it upside down.

We're just going to loosely tighten it so we can get it in place on our bar.Move over to our bar, slide this into place. To help out with this, we're going to flip it on its side here like so. Now we'll take our measuring tape here and measure out the distance between the two towers. You'll find this in your instructions.Move this out a little bit. Now normally what you would do, is you would find the center of the bar and measure out to both sides.

We already know where we had to be at so, kind of cheated a little bit. There we go. Now we'll tighten it down. I'd like to point out something here in a second. That's the tightening tool that comes with the kit.

It does give those audible clicks so you know when everything is torqued to its specifications without overtightening it.Now, one thing I'd like to point out, looking at the underside of our tower here, you're going to see three notches on each side here. One, two three. One, two, three. Knowing which side is the front is very important because that determines the pitch and the tow that you set. The pitch is on this side and we have it set to B, which is the middle notch. The first notch, A, B, C, and so on.On the other side the tow is set to two. One, two, three. We tighten it down with this screw here, which has already been done. Just be sure to take a look at this in your instructions when you're tightening everything down.Next, we'll take our pad here, pointing out that the arrow's going to be facing away from the vehicle, we'll snap that into place on the bottom, and now we're ready to set this on the room of our vehicle.Set it down gently, as to not damage our vehicle while we're doing this. Now, at this point, we're going to measure from center to center of the bars on both side to keep it even, and then we'll make sure that's it's even side to side too.Alright, we're going to want to make a couple adjustments here. Double check the measurements since I kind of had to move it a little. Alright. Looks like we're even on both sides too. Now we can open up our rear doors and start installing our clamps. This isn't necessarily the steps that they have you do in the instructions, but, I find that it make it a little bit easier on us while we're installing this, so we don't have the clamps accidentally making contact while we're setting them into place.So, our first step is we're going to loosen up the bolt here. You can see how this raises up like so. We're going to take our included clamp. We're actually going to loosen this up a little bit, going to push that in, and then, we're going to tighten that bolt that we just loosened up. You see how it's now going against the vehicle. We'll repeat this process on the other side as well.There's some other items you can put on this roof rack system. It can be anything from your ski and snowboard carriers to your kayak carriers as well. A wide variety of objects. Once we have this loosely installed, we'll get it snug up against the door frame on both sides. We'll go back and forth until it's completely tight, and then you hear those clicks from the tool. See how it's tightening down around there There we go. Close that up.Now we can put on our end caps on both the bars and our towers. I'd like to give you a couple final measurements here to give you an idea of how high it sits off the roof once it's installed. From the center of the roof to the bottom of the bar's going to be about two and five eighths of an inch, and from the center to the top is going to be about three and five eighths inches as well. So, that's more than enough space for your accessories that wrap around your bars, so it's not going to make contact with your roof and scuff it up at all.Also, you can still utilize your sunroof once these are installed as well. These bars do have a carrying capacity of 220 pounds once installed, but you should always check your vehicle's manual to make sure your roof can take those weights and go by their recommendations.There you have it, for the Yakima Round Bar Roof Rack System on our 2016 Honda Pilot.

I'm happy that this allows me to save money by using my old round bars on my new vehicle, with only the purchase of new "towers" and these adapters.

Its working great!


Kimberly has shown that great customer service is not dead! etrailer and Kimberly are great to work with and have earned my business and will always be the 1st and last place I look for my rack+ needs!
As for the application, I needed more space to fit my cargo box on top of my 4Runner TRD Pro’s rack. I came up this this… Thank you!


I have been using Yakima racks for around 40 years and have never had any problems. However, I am amazed at the price increases over the years. Etrailer prices were by far lower than most. Overall, a very excellent purchase.


The rack has been so useful since I purchased it. Staff at were exceptionally helpful in getting the best option for my car and answering questions. I recommend this company, for its 110% customer service, excellent prices and timely delivery.


Kit worked perfectly on my 2021 Subaru Forester. The whole install took 30 minutes. Never been disappointed with etrailer.


One quick phone call and Gwendolyn figured out exactly what I needed for our new car to use my old Yakima rack.


Great products though, again, written instructions would have been nice.


The Yakima roof rack system is an Outstanding product. I purchased the product to replace the OEM roof rack because it was too flimsy to carry the tandem bike mount and my bike. The Yakima roof rack is solid and provides me the peace of mind while hauling my bike on the roof of my car. etrailer provided the product for the best price as always.



Still an outstanding product.


Haven’t used them yet but they should work as expected


Installation of the hitch, wiring,rear bike rack, and new roof rack towers went well. I didn't set any speed records, but I was more concerned with doing no damage on a new 2019 Toyota Sienna AWD van. The hitch fit up well per instructions except that I was able to work around the exhaust without lowering it. Underbody panel and rear fascia did both need to be removed. Very happy with the end result. The new van is now set up to haul the bikes and canoes and move my log splitter.


first try was missing what was needed
helped. It was great!


Works great to use my round bars on the Skyline towers.


E trailer has me me spoiled yet again! If only I could expect this level of service from other suppliers.


Installation was relatively easy, instructions were clear. "Snapping" the bases into the towers required more force than I expected, but that speaks to the adapter's durability. I just wish Yakima would manufacture their stuff anywhere other than mainland China.


Great service - great price


Roof rack parts were ordered correctly and shipped quickly.


Product works as advertised thus far. When you buy the yakima towers, you are required to purchase these as well to fit the rounder bars (I feel sure there are other adapters for other bar shapes). These should have come with the towers in my opinion, and I resented having to shell out more $$ to purchase these "must have" adapters to mount my bars. 3 star overall rating based on function, price. Delivery and packaging was top-notch through etrailer.


Went Over and beyond on helping me solve a difficult problem on
how to fine and put a roof rack on a very difficult car...
Best Customer Service of any company I have ever worked with.
Great service before and after the sale to make sure everything
went smoothly. Can’t thank them enough. Very happy customer.


Ordered new towers and clips so as to use my old-school round bars (I bought these at least 18 years ago, maybe even earlier) and bike and canoe accessories on a new vehicle (naked roof 2018 CR-V). Installation was tedious, as usual, but not difficult and the written instructions were straightforward. Youtube helpful too but not necessary. Have hauled bikes and the canoe in high wind on the interstate (no more than 65 mph though) on the CR-V and so far so good. Have had excellent results with Yakima racks on 3 vehicles now (2 sedans and now the CR-V) over last 28 yrs. This is my first purchase through etrailer. Very pleased. Good price, excellent service online and via phone, rapid delivery. Highly recommend.


As always an exceptionally well designed, quality product. Yakima has never disappointed me for more than 25 years now. I still use some of my original rack package. etrailer, per usual, had a great price and wonderful instructional videos. Shipping was fast and everything was perfect. It’s amazing that Yakima can make racks fit so many cars like it was a custom job. This was just a piece of an entire roof rack base with cross bars. Excellent stuff


Bought as a pkg for my 2017 Golf R with Round Bars since I had a bunch of Yakima bike racks and a canoe gunwale rack for my old Yakima set up. Installation was easy with good instructions. All measurements from the Yakima site appear to be spot on. shipped these out quickly and all parts arrived without damage.


Thanks to Cody and retailer team


I've got a bunch of 20yo "vintage" Yakima gear that is all setup for the round bars. I'm very happy that this adapter is available to use with modern flush factory rails and Ridgeline towers.


The Yakima product I purchased for my 2009 Subaru Forester installed in one hour. The rack is the equivelent to having an manufacture installed rack for less the cost. I am abslutely pleased!


Standard Yakima Equipmemt. Availability is sketchy but had it in stock!
