Video Transcript for Yakima Roof Rack Installation - 2017 Chevrolet Express Van

Adam: Hi everyone, Adam with Today we're going to be taking a look at the Yakima round bar roof rack system on our 2017 Chevy Express.This is going to be a great addition to your Express van just because obviously we're going to be able to fit quite a bit of passengers in here, and it's always nice when you're going on vacation and you have a lot of room just to kind of relax on the long drives you may be taking, so luckily we can put either all the gear that they may have with a cargo basket or a cargo box up on top of here, or if you want to carry all your canoes, kayaks, or even a decent amount of bikes you can put them up here as well just so all your passengers will be nice and comfy.These are the 66" round bars that we have on top of our Express van here. They are made of steel with a nice powder coated finish, so they are going to resist against rust and corrosion over time. Also they will have a weight capacity of 165 pounds, but make sure that your Express van can handle that kind of weight.Honestly, with 165 pounds you can use these yes, for all the recreational stuff you may be doing on your vacation, but also for work. You can throw lumber up here, drywall, even a couple ladders. All you got to do is just make sure it's tied down properly and then you're ready to hit the road.So let's do some measurements for your guys.

From our roof to the bottom of our bar we are going to have about 4-3/4", and from our roof to the top of the bar it's going to be a little bit underneath 6", so we're going to have plenty of room to be able to fit even some of those attachments that are going to wrap underneath and around these bars. Even if they are bigger mounting hardware we don't have to worry about it rubbing against our roof.It is relatively easy to install on the roof, so let's just go ahead and show you how. Okay, so the first thing we want to do is we're going to have this little lip here. It's made of plastic. You get a little rubber boot and all you really need to know is you see this little dip right here That's going to be facing up towards our tower.I found it easiest to kind of like just spread it out and get that hole going and then kind of pull it a little bit.

I'm going to have to push that top lip up. Then you do the same kind of thing to the other side. Just make sure it's nice and tight and just flush with this lip. You're going to have to mess with it a little bit to get it to fit on there really good.So now that we have that installed, we are going to want to loosen this bolt here on the underneath. There is a tool included, but once you get it loosened most of the way you can actually just kind of rotate this assembly and that's going to allow our bars to be able to slide in there, because when we tighten it down it's going to push this little black piece up to lock the bar into place.So we're going to take it and this lip that we put the boot on is actually going to sit in this little divot here on the roof.

Seat it down into that little groove there. Then of course this metal part is going to be underneath this lip here.So we can either go ahead and grab the bar or just place it on the other side. If you have a specific bar width that you want to meet, definitely measure all that out. I'm going to put it about here, and I'm going to go grab our round bar.Okay, so you see how these towers are kind of facing inward That is the orientation that we want on both sides, and of course we want those facing the same way as well. This is not right and this is correct.

So that's something to keep in mind. If you have the caps on your round bar already installed, you're going to have to remove them, and I'm actually going to start with this one here. Slide it all the way down. Grab our other one. This might be a little bit easier with an extra set of hands, but I'm going to see if I can get it done all by myself.So now with those on our bar we can gently lay it down, trying to get it into the right spot. If you get one side kind into place you can just kind of lay it down a little bit and then go and fasten and get the other side kind of into place, and then we'll go ahead and fasten them all down.This wouldn't be a bad time to get the measuring tape out, making sure that the distance between the towers on this side and the distance between the towers on that side match.Sometimes if you have a more bubbly roof this bracket that hooks underneath this lip on the back side, it might be rubbing against your roof. We do have extra little rubber bumpers here, so if we are having that issue we can actually just put that on the backs of the bracket to prevent any wear to your paint, but in this instance we are not having any of those issues, so we won't be using them.The next step, we have a little push knob here. It's going to thread into our tower, and as we thread it in it's going to pull the top part of this metal section here back towards the tower, so then the bottom part is going to go into that groove, giving you a secure fit. As you can see, it's doing its thing. You're going to have a decent amount of turns. That should get it pretty tight. Give it a good wiggle. Then you can go ahead and do the same thing on the other side.One thing I do recommend getting is you can get some locking cores so someone can't just come up to this and just undo it and grab your roof rack and run off with it. We do sell those separately at, and you'll get keys with your kit just to give you that added protection.So before we fasten down our round bars here so they're nice and tight we're going to use the fact that they're loose to just make sure that they're even on both sides. You can kind of twist and get them nice and even. You can grab a tape measure if you want, but if you have them where you want them, which I do, you can go ahead and take that same tool that we used to loosen up the bolt and we can actually go ahead and tighten it. So now the only thing we have left to do is install our caps.Well everyone, that's just about all you really need to know about the Yakima round bar roof rack system on our 2017 Chevy Express.

Yakima stuff is pretty good. If it were not so over priced (and this retailer gave the best deal) I'd rate it 4 stars. However, I know from past experience that Yakima bars, despite coating on the current bars that is significantly thinner than older bars, will rust if used near water. They sell this stuff for water sports! And then act surprised that it rusts. Since I have a lot of their stuff and old rusty bars I bought these as a replacement despite my misgivings.

The foregoing is NOT a criticism of this vendor who sold the stuff at a good price compared to what Yakima wants and delivered it promptly

Bill S.


Nothing has changed. I just used the bars while evacuating me and water toys during the recent fire. All worked. Great vendor who checked in to see how things are going after a year. Hes great, Yakima remains pretty good but too expensive



Done. Thanks for the great service. you and your company do a great job and the followup you provide is so rare as to be non-existent these days. Much appreciated.


The yellow pads on the crossbars are
pool noodles secured by zip ties. They provide padding for a third or even a fourth kayak.


So far so good. Have had hitch for a year and it’s a game changer. Can reveal it quickly and throw on a bike rack to carry 4 bikes including an ebike. Amazes me that it’s so solid. But it is. And invisible when not in use

I bought a new bottom plastic panel for my Tesla model 3 from Tesla.


The crossbars are outstanding they are working perfectly with the towers I had to buy for my Honda odyssey roof rack I forgot the name of them I have my YAKIMA space Cadet rocket box on top of the bars in addition to my YAKIMA ski racks


These extra long round bars have been awesome. They allow us to carry 2 17ft long canoes on our car or a skybox and a canoe. They poles are sturdy and allow for plenty of storage.

My only recommendation would be to add a wind breaker because the bars are the least arrow dynamic and make noise over 65mph.

The Yakima bars I used for the roof rack system on my truck are great. Now, combined with the rack system on my topper shell, I have the length to support long objects like long boards, boxes of siding or ladders. However, it is the fantastic customer service from that will have me going to them the next time I need items for my truck. I tried to order this rack system from a competitor and waited 4 months before they finally just gave up and cancelled my order. One call to customer service and I had the complete rack system I needed in less than three weeks. The representative I spoke with spent over an hour helping me identify the items I needed. That is the kind of service I will not forget.


Been using Yakima products for decades. First use as a teen on a 1974 Chrysler Newport for a canoe. Still buying their products. Handing down canoe with Yakima racks for their vehicle. Why change a good combination?

Jeep Wrangler

I received the Rain gutter riser, 66' round bars, boat loader and SKS lock cores all well packaged and in good shape. These are for a 2020 Jeep Wrangler JLU Rubicon. The products were easy to install and will work great for loading and transporting my Hobie Outfitter Kayak. The Outfitter is a heavy kayak at 75 lbs unloaded. The Yakama Boat loader makes it easy for one person to load and unload the kayak. The rain gutter mounts and round bars securely hold the kayak for transportation. When not transporting the kayak the whole system quickly removes.
A big plus with ordering through etrailer is the excellent custom service, they will be my go to for future orders.


It's hard to find Yakima parts. I own a Rack and Roll trailer and I know. Got these round cross bars at a great price. Free shipping. And most importantly, even with all the current shipping problems I got them in just a few days. These guys hustle and really work for your business. I'm soon getting a new suv and will absolutely buy my trailer hitch from etrailer.

1987 Volkswagen Vanagon

the part is what it is. all prices are similar online. What sets etrailer apart is the customer service. you call and you get an empowered, cheery, competent individual. I had two cancellations I did (not their fault) and they handled both quickly, easily, and with a cheerful disposition. Excellent customer service.


Bars work great.

2013 Toyota Tacoma

One of the few retailers with these in-stock, they arrived in time to get my racks up and running.



Over the past year, my Yakima Raingutter Towers and 66 rd bars have supported my iKamper 2.0 2X rooftop tent beautifully.


Exactly as pictured, in new condition, ready to go on my truck. I needed to find round bars, as I was using my bike racks from my old system from my Subaru Outback transplanted onto my Nissan Frontier.

2012 Subaru Outback Wagon

Heavy duty. Just right to haul two roof top kayaks. Should handle Thule Hullavators on each side.


no end caps for this price is really not very good


Good 'nuff. Used Yakima for several years for ski racks and bike racks. No disappointments.


Works fine, but end caps are a bugger to take off.

2008 Chevrolet Silverado

Very pleased with the product and experience with etrailer. Product was shipped and received on time! Kayaks are on the truck and ready to travel!


Works great



After 1 year the cross bars are still as good as they were on day one. Excellent product.




Poles are working out well.



Exactly as described. Works great


Very easy to use and received promptly. Great!

  • Will the Shorter Yakima Compact Truck Ladder Rack Uprights Fit on a Full-Size Ram?
    For your 2015 Ram 1500, the confirmed fit is the Yakima Outdoorsman 300 Ladder Rack with 66" CrossBars for Full Size Trucks # Y01137-Y00410. The fit you are looking for is the same width, but the shorter height that you find in the # Y01136-Y00410 which is the same system just shorter at 26-1/2 inches versus 29 inches tall. This will reduce your cab clearance, but it will fit the same other than that.

  • Fit of Yakima Outdoorsman Ladder Rack on 2007 Nissan Titan
    According to Yakima, their # Y01137-Y00410 is indeed a fit for your 2007 Nissan Titan. The crossbars are 66 inches long, and have a 300 lb capacity which will allow all kinds of flexibility in carrying gear for work or play.

  • Recommended Roof Rack for 2006 Dodge Sprinter
    Yes, we do offer roof rack options for a 2006 Dodge Sprinter which mount to the rain gutter channels.

They are made of galvanized steel so they are both strong and long lasting. I have linked our watersport carrier selection below for you as well.

  • Will Yakima Outdoorsman 300 Fit with Trail Rail System on 2020 Jeep Gladiator
    According to Yakima the Trail Rail system will need to be removed in order to use the Yakima Outdoorsman 300 # Y01136-Y00410 on your 2020 Jeep Gladiator. This is the case for all of the Yakima ladder rack systems. Currently (August 2019) there are no other ladder rack options so if you are wanting to use a ladder rack with your Gladiator you'll need to remove that system.

  • How to Fit Two Sea Kayaks and a Thule Cargo Box on a Honda CR-V with Yakima Roof Rack
    I may have an option for you, but you will most likely not be able to fit two kayaks with J-style kayak carriers and the Evolution 1800 cargo box on 48 inch or 60 inch crossbars. Instead, I recommend looking at the Yakima Kayak JayLow, # Y04073. The JayLow can stack the kayaks on their sides giving you more room for the cargo box. You may need to upgrade to the 66 inch crossbars, # Y00410, due to the size of your cargo box, but that will also depend on the size of your kayaks. If you place...

    Per Yakima, a roof rack installed on the Wrangler Unlimited with the # Y00101 Drip Rail Towers will be limited to carrying snow products like ski and snowboard carriers. This is due to the limited capacity of the drip rails and the maximum bar spread of 24 inches. Yakima mentions a maximum allowable weight load of 100 lbs, including the weight of the rack itself.

If you want the 29 inch uprights with 78 inch crossbars you can use part # Y01137-Y00411. For Ford F-150's beginning with the model year in 2009, Yakima determined that the 26-1/2 inch uprights, # Y01136-Y00410, are sufficient to clear the cab of F-150s since the truck bed sides are higher.
