Replacement Rack Clamp Knob for Thule Xsporter Pro Ladder Rack - 852-3170001

Average Customer Rating:  4.8 out of 5 stars   (50 Customer Reviews)


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.


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.


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


Replacement parts for my Thule Rack


Magic. I lost one somewhere on the happy to have found a replacement here, it arrived on time and did not cost an arm and a leg. Thank you.


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


Arrive quick, just as expected.


Fast shipping! Knob worked perfectly!


Perfect replacement.


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 ..

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.


Great service!


Part shipped on time and has been in use since I installed it. Good service!


Received the ordered part only to learn that it did not include the pin that attaches to it. Don't know yet how to proceed. We'll figure it out but it's costing us more down time. The parts catalog needs to be more clear as well as easily accessable.

If you need the pin that goes inside the Xporter Pro base assembly, the only way that is available is with the entire Replacement Base Assembly. I confirmed with my contact at Thule that they do not offer those parts as individual replacements. The replacement base assembly for the front left/rear right is part # TH7521368001

and the replacement for the front right/rear left is part # TH7521367001

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.

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.


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.


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.


Exact replacement! The threaded bushing IS brass just like the originals even though it appears to be zinc in the photo. Great part!


Great service! I live in Hawaii and I received my rack replacement parts within 4 days of placing my order so I could get my truck racks back in service without losing a weekend! The parts I ordered were high quality and fit perfectly. I'll definitely be using ETrailer Corporation 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.


Exactly what I ordered. Seems to take them a while to ship in stock items though.


Fit my Thule rack perfect


They did ship me the wrong part but shipped me out the part out over a holiday weekend. Got it Monday night. Easy no hassle service. Hope they earn a 5star next time.


Very good customer service and the product i ordered was exactly what I needed thank you and aloha
