It took a while to arrive, but it was exactly what I needed to attach my existing Yakima rack to my new car. It is tough to find the right part sometimes, but I found it here!

Works great after a year. We managed to crack one of the pieces by driving under a low clearance spot, but that was totally our fault.



by:

These Universal mounts were a nice affordable solution for me. My Yakima racks were set up to be mounted on a trailer. I have a Subaru outback and needed a universal mount so that I could use my racks on my outback crossbars. Perfect solution.



by:

Thought I was getting hardware to attach my ski had to order separately



by:

Exactly what I was looking for to get my older Yakima bike racks to fit on the standard cross bars of my MDX.



by:

We decided to try out skiing as a family this year. I haven’t skied in 20 years. These worked perfectly for attaching my circa 2000 era Yakima Powderhounds to Thule Aeroblade cross bars on our minivan. These mounts are pricey, but I’m so glad I didn’t have to buy a new ski rack!

The mounts fit almost flush to the top and bottom of the cross bars and there’s no play when properly tightened down. The mounts come with two bails, I used the A one and clipped it into the lower hinge on the backbone. YMMV but you want the top and bottom hinges to conform to the shape of your cross bar as best as possible.

If you find the adapter hard to install into the powderhound, start towards the middle of the ski rack, twist them into place, then slide towards the end and line up the holes.

Minus one star because these are so ugly (the opening of the clamp facces forward) and definitely not aerodynamic, but roof rack attachments rarely are. Function is more important here and these universal mighty mounts definitely get a 100% there!

Shipping was fast and good communication from the etrailer folks throughout the whole transaction.



by:

Super easy to attach and set up. Perfect for for my 2020 Subaru Outback crossbars.



by:

This was shown to work with Yakima Kayak racks. It does fit, but it is very wobbly. It feels very unsafe. I used it for a short drive and the kayak moved all over. The reason is both “adapters” go on one side of the rack, leaving the other side with no support. This may work for other attachments, but not the kayak racks.



by:

It is not etrailer's issue but Yakima in not being more explicit as to what racks this works on. Also Yakima not manufacturing mounts for J Saddles



by:

Worked great for attaching my vintage Yakama Lockjaw to the new aero bars on my 2018 Subaru Impreza.



by:

Perfect adapters for my 2018 Toyota RAV4! Installed Hullyrollers and Mako Saddles on them. Worked great on the Toyota factory racks.



by:

I have oval Rhino cross rails on my car. I have an old Yakima standup bike carrier. This product brings the two together perfectly.

Still working great.



by:

I had old Yakima Powerhounds mounted on round bars, but need to mount them on the factory bars of my new Crosstrek. These Universal MightyMounts saved me from buying a new ski add-on. Only drawback I can see is the system doesn’t lock to the car like when I had them mounted to my round bars. However, I usually view the rack as a means of transport rather than storage.

etrailer.com’s customer service was solid. I made the purchase around April, but due to the part being back ordered, did not revive them until August. etrailer.com emailed me updates about once a month until I received my order.



by:

This product was awesome in allowing me to mount an older tandem bike rack onto the factory Audi Q7 roof rack. Held our road tandem with no issues during 1000 miles at highway speeds (I.e. 80 mph). Slight concern that rubber pads wilm go missing over time.



by:

I searched the internet trying to understand what I needed to convert my Yakima Hullraisers and Lockjaw to work with my new Subaru Outback. My old set up worked on round Yakima crossbars. The internet was not clear at all about whether there was a workable conversion to the built in crossbars of the Outback. Finally I etrailer and talked to Jordan. He contacted Yakima himself. He identified exactly the parts I needed, and then called me back. Very old school and very effectively. Everything worked as it should.

A quick note, the Hullraiser conversion kit doesn't include any instructions -- Yakima gives me more engineering credit than I deserve. For those who might be doing the same conversion, get the instruction manual for the Hullraiser Aero which shows how it is done.

Thanks Jordan



by:

I was amazed at how quick I received my order. The mounts I ordered were exactly what I was looking for to mount some Yakima bicycle roof racks I purchased used on craigslist. I thought I wasted my money on the racks when there was no mounts with them. I went to REI and was told I was going to need a whole different system that would cost over $300. The mounts from etrailer I bought, REI had no idea they were available. I plan on buying another set soon.



by:

I needed to adapt hundreds of dollars worth of Yakima Kayak and Ski carriers to the Aero Rhino Rack I bought from eTrailer.com.
Ricky researched the issue, contacted Yakima, confirmed the correct adapters and I had them in less than a week.

Fantastic customer support - these guys came through for me.

by:

very good for multiple style crossbars
they
are plastic but seem well made
i am using them on Hully Rollers and Saddles which required
some ingenuity to make them work but in the end work well

ETrailers were honest about delay is supplu chain
Having said that there time estimate and delivery were spot on
i am ordering a second set for use with my second kayak



by:

Brackets for older Yakima bike rack were needed for a different roof rack on another car. The eTrailer web site was easy to navigate and lead me to exactly what I needed. Received the shipment quickly.



by:

I just bought a tadpole trike and I wanted to place it on my factory installed roof rack for my 2016 Toyota RAV 4. James A. was fantastic on trying to make this work. He came up with using the Yakima Boa wheel trays and the Yakima Universal Mighty Mounts. Only 2 of each was required due the length of the trike. The optional "B" lower bracket was needed. The set up is working very well. Thanks James



by:

I purchase some Yakima universal Mighty mounts to mount my bike rack to my roof rack. I purchased them from etrailer. Great transaction, great communication and emailed me with the mounting instructions when the package was delivered.



by:

I was very happy to find adapters which fit my Yakima accessories, specifically in this case a Kayak rack, to a BMW rack which I just picked up. Haven't install them yet but it looks like everything needed is included and her order and delivery were very smooth.



by:

The Universal Mighty Mount Y03590 is the only adapter that fits the 2017 Subaru Outback factory crossbars. I learned that after ordering the 39H that was too big. Thank you,Greg, for helping me return the 39H adapters and order the Universal adapters.

by:

The conversion from round to flat cross bars went great.



by:

the universal mounts work well
you need
to adapt them to use them with roller mounts
and saddle mounts but that is not difficult
the direcions do no show doing that but essentiallty you have to reverse the
direction of the bolts to make it work

Great product and wonderful doing business with eTrailer.com

  • What Else is Needed to Mount ARB Universal Bracket
    Hey Dave, Thanks for the photo, and while I can't post it I can tell you exactly what was used there for the mounting on the crossbars, and that was the Universal MightyMounts for Yakima Roof Mounted Accessories # Y03590. Just keep in mind the crossbars on your 2015 Chrysler Town and Country can only be up to 4" wide and 1-1/2" tall to work with the ARB Universal Awning Bracket # ARB57FR. We've also never tried this so I need to mention I don't know for certain if this will work for...

  • Will Yakima 39H Mighty Mounts fit on Rhino-Rack Aero Bars on 2018 Jeep Grand Cherokee?
    On your 2018 Jeep Grand Cherokee with black and chrome roof rails the Rhino-Rack RVP Roof Rack # RRRVP27 is confirmed to fit. The Rola APE rack has a slick aftermarket look and will mount directly to the flush roof rails on your 2018 Grand Cherokee. The crossbars in both options are 3-1/8" wide x 1" tall so the Mighty Mount 39H Accessory Adapter for Yakima CoreBar and JetStream Crossbars - Qty 4 # Y03539 will fit and allow you to use your older Yakima ski rack. I've attached photos to...

  • Will Older Mighty Mounts Work on New JetStream Bars?
    I called Yakima to check with them since the 9v and 10 v Mighty Mounts you're referring to have been discontinued. According to Yakima, the new JetStream bars are larger and more aerodynamically shaped compared to the older style of crossbars that the Mighty Mounts were created for, so they most likely will not fit. The closest alternative are Yakima's Universal Mighty Mounts # Y03590. These can be secured with Lock Housing # Y07220 and SKS Lock Cores # Y07204.

  • Mounting Hardware Needed to Mount Older Yakima Accessories to Aero-Style Crossbars
    If you have a variety of older Yakima products that you want to mount to crossbars that are 2-1/2" wide x 3/4" tall then the Universal MightyMounts # Y03590 would be your best bet. These adapters fit a wide variety of Yakima products but they are somewhat specific. If you can let me know what products you are wanting to mount them on I can see about verifying if these will fit or what other parts you may need.

  • Will Universal MightyMounts Fit a Yakima LockJaw Bike Rack and VW Factory Roof Rack
    The Universal MightyMounts # Y03590 will work with your Yakima LockJaw bike rack. The MightyMounts are designed to fit crossbars up to 4 inches wide and up to 1-1/2 inches tall. Bars that are either more than 4 inches wide or more than 1-1/2 inches tall will be too large for the MightyMounts. MightyMounts only come in a set of 4 so if you need 6 you will need 2 kits and you will have 2 spares should you need them in the future!

  • Universal Mighty Mounts Fit to an Older Fat Cat 4 for Installing on a Thule Aeroblade Bars
    I spoke to my contact at Yakima and he informed me that the Universal MightyMounts part # Y03590 should install on your older Yakima Fatcat 4. Basically you will need to remove the mounting hardware you have on the Fatcat and install the # Y03590 on place of it. If you check out the installation instructions I attached to the right and scroll down to the "Snow" section you will see how it installs.

  • How to Mount Yakima SpaceCase Cargo Box to Factory Crossbars on 2020 Subaru Forester
    I do have a solution for you, however I reached out to my contact at Yakima and he said the Universal MightyMounts # Y03590 aren't compatible with your older SpaceCase Cargo Box. The mounting hardware for the SpaceCase is a bit different and you won't be able to properly attach the MightyMount clamps. Your best route for mounting the SpaceCase to the wider aero-style factory crossbars on your new Forester is to replace its existing hardware with part # 8870098. This kit consists of similar...

  • Adapter Recommendation that Can Fit Yakima FatCat 6 to Audi Q8 Crossbars
    The universal MightyMount part # Y03590 is a fit for the older style of Yakima FatCat 6 that you have and can fit crossbar sizes up to 4 inches wide and 1-1/2 inches tall so it should work well for you. I don't have the year of Q8 that you have though so I wasn't able to fully confirm this though. Send me the year of your vehicle and I'll be able to get a full confirmation.

  • What Yakima MightyMounts for Yakima Roof Mounted Accessories Fit a 2011 Toyota Sequoia
    I checked with Yakima and apparently you will not need MightyMounts to use many of their accessories. This means that their products are a direct fit to the factory crossbars on a 2011 Toyota Sequoia. But you could use Universal MightyMounts, # Y03590, if you had a Yakima accessory that did not fit. I have included a link to the installation details and a link to a video review.

  • How Do You Assemble the Yakima Universal MightyMounts
    If you have the Yakima Raptor Aero Y02093 then that bike rack already comes with feet that mount to factory bars. The original Raptor only fit the round bars so if you have the original Raptor then MightyMounts # Y03590 can be used. The MightyMounts are 2 pieces, a top and a bottom and the hardware. The nut that the bolts thread into is located inside of the top piece above the pad part that fits in the top piece. What you would do is lay the bike rack on its side, push the bolt through...

    For the regular Yakima ButtonDown you would need to use MightyMounts # Y03590 to attach the carrier to the factory crossbars if they are not larger than 4 inches wide and 1-1/2 inches tall. If you have the ButtonDown Aero then you can use # Y8860040. This item is a single unit so you would need 4 of them total. This foot will fit crossbars up to 3-7/8 inches wide or 1-1/4 inches tall. I do have a good solution for raising this rack further away from the vehicle to allow you to fit those...
