Video Transcript for Thule Roof Rack THXADAPT3 Review

Today we're taking a look at the Thule Xadapt3 Load Bar Adapter Kit. Now this kit allows you to mount a Hullaport Kayak Carrier onto the Thule Exporter height adjustable load bar. So those load bars are a little bit thicker than standard aero blade or aero boars and so that's why this kit comes with the longer bolts. It's also designed to fit the Thule Cascades Ski Cargo Box. The adapter kit comes with eight bolts and the bolt size is M6 X 80 mm.That's going to do it for today's look at the Thule Xadapt3 Load Bar Adapter Kit.

Thule Xadapt3 Xsporter Load Bar Adapter for the Hullaport - THXADAPT3

Average Customer Rating:  4.8 out of 5 stars   (144 Customer Reviews)


It is as advertised. Enabled me to put my hull-a-port onto a new car with a thicker rack


Great product with Awesome customer ser vice!


I purchased the THXADAPT3 to be able to install my Thule 834 hull a port kayak rack onto the 1.5" square bar of my Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars.
I believe it will work but I wish the bolts were a bit longer. See images.
I have been satisfied with etrailer's support and service.


Not even close to fitting on the xsporter.. inch easily to short…had to go get longer bolts at the hardware store


These bolts solved the issue when there was limited thread engagement on original bolts assembling hullaport kayak carriers on aeroblade bars. I've made many trips to the water without needing to worry a nut might vibrate off. Fits nicely, performs well. Would have been hard to find elsewhere.


I had trouble finding carriage bolts that would work for my Thule kayak cradle on Amazon and many other popular sites. After toying with search key words in Google, I finally stumbled upon eTrailer's link to these 80mm carriage bolts. Their product selection made it a simple choice as to where I would make my purchase. The bolts needed to be of a m6 diameter, which is extremely difficult to find in traditional brick and mortar stores. After receiving the product and using them on my kayak cradle, I find them to be a perfect fit for my needs and feel extremely comfortable with them to hold my equipment steady.


These bolts should be included in the Thule Kayak carrier kit, since the kit claims to fit factory roof racks with 2" diameter cross-bars. They won't fit unless you have these longer bolts.


The metric carriage bolts we ordered for our Thule kayak racks were not available elsewhere, and the quick service was welcome since we are ready to hit the waterways.


I ordered Thule adapter bolts and was surprised at how quickly they arrived. I had intended to purchase them directly from Thule but their minimum shipping cost was [...] and their website indicated that the item "should" ship within 5 days.

I found the bolts at, shipping was [...] and they shipped the next day. A very positive experience!


The order was processed immediately and received with no issue at all. Product is as described.



Quite well...the larger bolts were needed for kayak racks due to a different roof rack design. It worked out great and continues to do so.


Great service and customer service...great product as expected. I highly recommend using are awesome!


Called and spoke to Sam G at etrailer. He assessed my situation and needs, recommended the right product. I received my order quickly and had excellent communication from Sam G. I would definitely come back to eTrailer to order my roof rack or trailer needs.

Thanks Sam G!


I needed longer bolts to mount my Thule Summit on my VW Touareg. The OEM bars are very thick and the standard bolts are too short. These 80mm extended length bolts are the perfect solution.


These lag bolts work great just long enough for them to fit my Thule Kayak carrier.
Thanks for great service and a quality product.


Exactly what I was looking for to place my kayak racks on my vehicle. The previous bolts were too short to use on my current crossbars. This fixed that problem inexpensively.


I bought an adapter kit that Thule no longer provides but was available through It was delivered quickly, worked perfectly, no problems/delays. Great service.


Product was reasonably priced, came quickly, and fit perfectly on our Jeep crossbars.


Emailer provided amazing customer service for a product that cost much less than the competition. They emailed me to confirm the order when i placed it, again when it was shipped, and then today to verify that the order was delivered. Delivery was fast and well-wrapped. This was a great purchase experience.


Just what I needed. Fits the thicker rails on our luggage rack much better.


The part I ordered arrived as promised and was correct. The package didn't identify the size or length of bolts but just said "Adapter for the Hulliport". But it was the M6 X 80mm length which is what I needed.


Great site, better info than the Thule site and the search got me right to the parts I needed.


Item as described and authentic. Fast service and good packaging.



Excellent. Easy to change between racks.


Order arrived quickly and was exactly as advertised.


I received the product. They were exactly as advertised, in perfect shape, and performed the task as expected. Good quality.


Fast shipping and wonderful communication...Great product..What I needed.. Thankyou
