Average Customer Rating:  4.7 out of 5 stars   (83 Customer Reviews)


I wasn't familiar with etrailer and had never ordered from them before. My first experience with them was excellent. My order was correct and arrived promptly.


I tried to order this product directly from Thule and was told that I would has to purchase the entire base assembly. Thanks to etrailer I was able to save a couple hundred dollars and just purchase the part I needed. The customer service was great and my product arrived quickly.


Exactly the right part for my Thule truck ladder rack. I got the rack used and this height adjuster was corroded and frozen into position. The replacement was a hard item to find on the internet. I am happy etrailer has it available. The price was good. It was shipped quickly, and a rep from etrailer kept in contact with me to make sure I recieved and was happy. I will use etrailer again because of this good service.


Fits perfectly!!!


super service thanks!!!


Same original quality. Good service from Etrailer.


Amazing service, would not hesitate to purchase from etrailer in the future.


best way to purchase Thule parts


Very quick response and delivery. Parts fit perfectly and saved me a bunch of money. Thought I needed to purchase new racks but breaking and replacing the clamp knob saved the day. Less than $10.00 per part including shipping was a great deal.



No issues or problems with replacement parts. Saved me a bunch of money replacing parts vs. purchasing new racks!


The product arrived and is as ordered. The staff at etrailer kept me informed of the shipping progress through a tracking number and personal emails. The only 'issue' I had was ordering from Canada I had to submit twice as the program did not recognize my address and unilaterally cancelled it. I would order again from etrailer.


Replacement parts for my Thule Rack


Perfect, just what I needed!


Good service


all went well with the purchase, with the technical guidance from etrailer and the self-installation


etrailer exceeded my expectations, this was my first order with etrailer but it won't be my last. I received my order promptly and it is of good quality and the price can't be beat. Thank you etrailer.

excellent, lasting longer than the original.


Just what i needed , great customer service from etrailer , they found the item i was looking for special order it and everything and it was not even an expensive item , but hard to find , thanks etrailer.



afer a year , everything is same as new , great product , will definetly buy again ..


Dianna was able to pull all of my information up even though it's been a few years since I ordered from you folks. You had product even the manufacturer did not have. I was dead in the water without this critical part for my Thule Rack System


I lost the rack clamp for my Thule Xporter 500XT adjustable rack when I removed the rear one for hauling branches. etrailer is the ONLY site where I could find a replacement. I didn't even see it on Thule's website. It's an exact match to the others and I actually received two with the order. I will be using etrailer in the future


Very pour not made to last. Bolt snapped without any on the rack


The knob is a direct fit for Thule Xsporter. I was able to replace all four corners of the base adjustment. I am now able to adjust the rack height for the proper application. Ordering through etrailer was easy with great shipping option. Very pleased with my purchase or any future purchase for parts availability.


Right part, Right price.
If there was
any downside it is that not all the parts I needed were available unless having to buy an entirely new complete unit. Probably the manufacturers deal and not this suppliers deal.
Either way, A few emailed questions & answers and I was able to get most of what I needed accurately and in a timely manner.
As it turned out I was able to find the missing bolt under some debris in my truck bed.
All in all, I'd use these guys again and so should you.


Easy to find what I needed on the website and order came in a timely manner.


I had my Thule Xsporter rack off my vehicle and the clamp knob (still attached to the vehicle) must have vibrated loose and bounced to the ground. Finding this replacement was a lifesaver.


Over time i have purchased several parts for my Thule rack from you.
Your site is easy to navigate, purchase is simple and shipping is reasonable.
Thank you for saving me from having to discard a very expensive rack, you saved the day!.....again.


the product from etrailer was described exactly as what was ordered and works exactly as described. shipping and the ordering process went smoothly. over all i am very happy with this purchase.
