Universal MightyMounts are a simple and economical way to adapt most Yakima carriers to almost any factory roof-rack crossbars. MightyMounts are specifically designed to fit popular factory racks and install easily with no tools.


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.’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. emailed me updates about once a month until I received my order.


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.


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


very good for multiple style crossbars
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


Works well with my Subaru factory cross bars.


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


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.

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


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.


I needed to adapt hundreds of dollars worth of Yakima Kayak and Ski carriers to the Aero Rhino Rack I bought from
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.



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


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.



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


The products I ordered were shipped promptly and were exactly as ordered. One issue pre-shipment was handled perfectly by customer service. Excellent experience, will return when I need similar items. Thank you.


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.


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.


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.


Great product and wonderful doing business with

After one year of using the Yakima brackets, the product is still great.

As expected, brand new mighty mounts!


It has been hard to find brackets for our square bar equipment to attach to new aero bars. These fit and work great. Thanks also to the product information on the eTrailer we site which allowed us to know these would work.


Just what I need to mount my Yakima hullrisers on my BMW cross bars. Arrived very quickly.


Been working great for me for about a year now! Awesome product.


I had questions on what i wanted to order. I called up and the people at the call center were very helpful. Later on i ordered the item needed, was updated on the shipping status and delivery was fast. Overall a great e-tailer to work with. Thanks!


Apparently Yamika discontinued making vehicle specific mounts. This fit my Toyota nicely and give the option for any other car. Worked on an older style ski rack as well.


Fit my rack on my jeep, good alternative to using Yakima items without having to replace factor rack
