Sturdy, support the roof rack well


I have used Yakima in the past so I know it will be a great product.
Alex J was very helpful in getting the order processed. And it was delivered in a quick time frame. All parts arrived well packaged with no damage.


Fast service, easy to work with!


The Yakima bars are a simple item. They fit my racks as I expected. Removing the existing bars and installing the longer bars took about 20 - 30 minutes. Using a tape measure to center the bars, and an allen wrench to tighten them in place were the only tools needed. After several times loading and unloading canoes, the covering on the bars is scuffed and gouged, but has held up well to the abuse I give it. They don't flex with loads strapped tightly to them. etrailer had the product in stock. Ordering on-line was quick, simple, and painless. Received the bars without damage and on time. I've ordered several items from etrailer and never had a bad experience.

The bars continue to function well. Hey, theyre just bars after all. No issues so far and I expect they will outlast the truck.


The crossbars are fine, I've had several different round bars and all good. The shipping from etrailer was poor. Both ends of the box were open and the bars obviously had scraped on something, damaging the coating. A couple pieces of tape would have solved the issue.

I will have our Customer Service team reach out to you.


Order was handled promptly thru weekend and ready for ups pick up the next day. Made it to destination as promised, item was exactly what I ordered (no substitutions). Highly recommended, Keep up your excellent work.



After using the rack for several miles, it seems that is holding up to my pop up trailer original tracks with no signs of decay or damage to any of my components, I do check for security after every trip and found no indication of slip or damage, looks like is going to be a good component for years to come.


I bought longer round bars to extend my Yakima rack outward from the vehicle. Replacement was straightforward. I bought the original system at the same time - q towers and round bars, and was provided with end caps for the bars. The replacement bars came without endcaps, and those on the shorter bars basically crumbled when I tried to remove them for re-use. New end caps would have been nice, or a reminder that purchasers might want to get more.

etrailer never disappoints! Every product I need, I check that etrailer has it before purchasing anywhere else. Thank you for the excellent service, the fast delivery, and the email updates on order status.


Ordered the 78" Yakima crossbars with end caps as I frequently going canoeing in groups in the Northeast. The long bars allow for a canoe and cargo (Rocketbox) or two canoes. I could not believe how fast the bars showed up on my doorstep! etrailer had what I wanted at the best price and the customer service was simply a bonus. Def will be back!


Item arrived in good shape one day before expected delivery. 78” round bars for Yakima rack we’re exactly as ordered.



Excellent- replaced crossbars that were bent and had the plastic covering cracking. This allowed winter road salt to rust the original bars. I hope these hold up better.


I am very happy with this roof rack. I use it all the time for hauling paintball gear. It even held up well with my 10x12 cargo net. This was an awesome purcahase.


Have had yakima products for many years - needed longer bars for two canoes - recommend yakima

Really excited about this product. Looks great and has great utility! Does not interfere with cargo capacity in the bed of the truck and is very sturdy. My truck has much versatility, now, with the addition of this Yakima system.

Yakima is a great system. Just needed to replace bars that were very old.

  • What Is the Wall Thickness of the Yakima RoundBar

    You don't want to go with crossbars wider than the mirrors of your vehicle. Doing so will make drive throughs and garages hard to get through without damage.

  • Recommended Ladder Rack for Two Canoes on a 2011 Ford F-250 Crew Cab
    Thanks for the picture! I checked with Yakima there's no specific distance with the Yakima Outdoorsman 300 Ladder Rack item # Y01137-Y00411 that states how far the canoes can be mounted over the cab of your 2011 Ford F-250. A good rule of thumb is three feet though. So long as you stay below the 300 lbs weight capacity and have them properly secured you will be good. The top of the crossbar for the Yakima Outdoorsman 300 Ladder Rack item # Y01137-Y00411 is 29" from the top of your F-250's...

  • Will the Universal MightyMounts Work with Round Crossbars
    Yes, the Universal MightyMounts for Yakima Roof Mounted Accessories part # Y03590 will work with Yakima Round CrossBars like part # Y00411. There isn't any sort of special adapter for this, the crossbar will just sit in the middle portion of the clamp and will become secure once you tighten the knobs. The rubber padding inside the clamps does a pretty good job of holding them in place on the round bars so they don't slide/tilt.

  • How to Carry 6 Bikes on a Roof Rack Using Yakima 78 Inch Crossbars
    The Yakima FrontLoader # Y02103 does require a crossbar spread of 16 to 48 inches. Crossbar spread is the distance between the bars, front to back. So it doesn't impact how many can fit across the crossbars. Yakima has confirmed that you can load 6 bikes on their 78 inch crossbars # Y00411. Alternating the bike between forward and rearward facing is definitely the easier way to load the bikes to avoid handlebar contact. You'll want to verify the roof of your vehicle can support the...

  • Will Yakima Outdoorsman 300 From a 2012 Ford F-150 Fit a 2017 Ford F-350
    I have a option but the Yakima Outdoorsman 300 Ladder Rack # Y01137-Y00410 for a 2012 Ford F-150 will not fit on a 2017 Ford F-350 since the crossbars 66 inch will be too short since the Yakima Outdoorsman 300 Ladder Rack # Y01137-Y00411 for a 2017 Ford F-350 uses 78 inch crossbars. The easiest option is to change the crossbars from your F-150's ladder rack to the 78 inch crossbars # Y00411 to be able to use it on a 2017 Ford F-350.

  • 78 Yakima Bar Compatibility with the Yakima Outdoorsman 300 and BedRock Kit
    The Crossbars included in the Yakima Outdoorsman 300, part # Y01137-Y00411 are the Yakima 78 inch Round Bars, part # Y00411. The 79 inch crossbars will extend past the end of the truck a bit, but will be compatible with your BedRock towers, giving you a widely interchangeable kit between the Outdoorsman and the BedRock. Given the width, you'll have a solid fit with the 78 inch bars. Yakima does recommend the 66 inch round bars, part # Y00410 as a fit for your vehicle to fit the bed...

  • Yakima Outdoorsman Ladder Rack and Kayak Carrier for a 2017 Ford F-250
    The Yakima Outdoorsman 300 Ladder Rack for full size trucks like your 2017 Ford F-250 is actually going to be # Y01137-Y00411. The one you asked about is for compact trucks. The Outdoorsman is compatible with all current Yakima roof kayak carriers because the bars are the same size as the roof rack bars. The most popular Yakima option is the JayLow, # Y04073. But you may want to consider a rear loading option with rollers such as # Y04083-04082 since trucks are so tall. I have linked videos...

  • Can the 66 Inch Crossbars Be Upgraded To 78 Inch Crossbars on the Yakima Rack and Roll Trailer
    I do not see any issues upgrading the 66" long round crossbars on the Yakima Rack and Roll Trailer part # Y08106 to use 78" long round crossbars like the Yakima Rack and Roll Trailer part # Y08107. In order to do this all you will need is the Round 78" CrossBars for Yakima part # Y00411. This is currently the longest round crossbar you can get for the Rack and Roll because their are special lighting requirements for trailers over 80" wide.

We do have the Yakima Outdoorsman 300 # Y01137-Y00411 that has 78 inch cross bars. The legs of the rack can be placed anywhere along the crossbars.

All Yakima round bars have an outside diameter of 1-1/8". These are made to attach onto the roof via roundbar adapters like # Y03536.

  • Are 66 Inch Bars on Yakima Ladder Rack Long Enough for a 2012 Ford F-250
    The uprights on the Yakima ladder rack # Y01137-Y00410 do lean in a little towards the center of the truck bed. But if you want to go with longer bars you can use # Y01137-Y00411 which features 78 inch bars; almost the same overall width as your 2012 Ford F-250!

  • Mounting Two Yakima ShowDown Kayak Carriers on 1996 Ford F-250 Extended Cab
    The Yakima ShowDown Kayak or SUP Carrier # Y04081 requires at least 3-1/2 inches of crossbar overhang beyond the feet/towers for proper operation. If the existing 58 inch bars on your F-250 overhang by just 1/16 of an inch then you will need bars that are longer by at least 7 inches. For this requirement the Yakima Round 66 Inch Crossbars # Y00410 will work perfectly to mount 1 ShowDown Carrier (this is actually the size Yakima recommends for your F-250 when using the 1A Towers).

  • Can 78 Inch Bars Be Used on Yakima 66 Inch Rack and Roll Trailer # Y08106 without Conversion Kit
    I spoke with my contact at Yakima and although the Round 78 Inch CrossBars, # Y00411, will fit on the Yakima 66 Inch Rack and Roll Trailer, # Y08106, with out the Crossmember Conversion Kit, # Y08111, we can not recommend doing this. Since the Yakima 66 Inch Rack and Roll Trailer, # Y08106, was not designed for the longer bars, the center of gravity would be altered which would increase the chance of turning over the trailer.

  • Recommendation to Transport Kayaks While Towing 5th Wheel Trailer
    Because of the overhang from a 5th wheel trailer the best solution for transporting a couple of kayaks while towing is with the combination of a single bar rack for the cab and a front-mounted load extender that installs into a front-mount hitch. For an all-in-one kit (excluding the front mount hitch) I recommend taking a look at the Rhino-Rack T-Load Hitch Mounted Load Assist and Support Bar # RTL002.
