Replacement U-Bolt for Thule Sidekick Cargo Box - TH02943

Average Customer Rating:  4.9 out of 5 stars   (237 Customer Reviews)


The U-bolt fits my weekender 627 perfectly saves me a ton of time installing my Thule.

Still works like a gem.

It was the wrong part and difficult to compare old thule parts to this company's newer non brand replacement parts. Sent back a different shipment of parts that did not work and had to prove they received my return with ups shipping confirmation to be refunded. Not too impressed with this company.


After losing a u-bolt from my Thule cargo box, I attempted to contact the company to acquire another one. I had to open two warranty sites to get on their replacement list. Long story short, I googled your company and within a week, the perfect sized u-bolt is here! Fantastic service, great price, fast delivery…thank you!


These bolts fit the SportsRack Vista XL cargo box. So if you happen to drive into your garage with your cargo box on and you don't fit, and need to cut the bolts to get the box off... They make the perfect replacement part! I ordered on Sunday and they arrived on Wednesday with 2 day shipping. So the parts made it in time to save our trip!


Perfect replacement for our Sears rooftop cargo box. Thank you!


I was searching for replacement brackets for my SportRack rooftop cargo box I purchased through [store] more than five years ago. I couldn’t find replacement parts—it appears [store] doesn’t sell parts anymore. When searching for the part numbers, I came across identical part numbers for a Thule rooftop cargo box. The only difference was that these part numbers had a “TH” in front of them. Just received the parts yesterday and confirmed they are the exact thing I needed, so I’m very happy I purchased from here.


These U-bolts are replacing the obnoxious mounting system that was provided with a model year 2015, X-Cargo Extreme, rooftop carrier.

I was slightly concerned with the inside stud spacing of this item, however it worked perfect. The hole spacing on the plastic carrier, exterior bottom support steel plate, and interior steel hold-down plate, are all of a slightly larger diameter, allowing this item to slide in. The minimal resistance provided by the bolt rubbing the insides of the hardware, is just enough to keep the u-bolt in place while you tighten down the spinners inside the carrier.

These bolts are being used on a 2015 Jeep Grand Cherokee, fitted with Mopar's factory style, airplane wing shaped, cross bars. ( They're relatively thin, as a thicker dimension bar might run out of stud length on the U-bolt uprights. )

etrailer should be commended for providing their customers a cost effective route, for simplified mounting.

An update on the etrailer u-bolts, for my x-cargo Thule style rooftop carrier. I have now used these replacement u-bolts multiple times, covering many thousands of miles. Theyre still working great! There are no issues with wear to the carrier or the Mopar aluminum cross bars, nor issues from rust or corrosion. They have been used on the beach in the ocean air, to the freezing North-East salt sprayed winter roads. Note: I did rub candle wax on the threaded studs to avoid freezing, in the cold My garage door height will not accommodate my vehicle with the rooftop mounted carrier, resulting in the carrier being taken on and off, quite a bit. That being noted, the threads on the u-bolt studs have held up well, with no cross threading or stripped areas. I would not hesitate to recommend this part to replace X-cargos terribly designed stock mounting system or another wide u-bolt design that has become damaged. Super cost effective alternative to other mounting systems!

I received this promptly and it was the perfect fit. Grateful to find a source for this product, and so cheap! I had been missing my fourth bracket for a year, and just zip tying the fourth corner of the cargo carrier to the luggage rack. NEedless to say, that was getting old. Note that while this was said to be for a Thule carrier, I actually am using it on a cargo carrier I got at Sears about 6 years ago, called the X-Cargo Sport 20. Description Item # 02872030000P Model # 90035P on the Sears website.


I bought this along with "Replacement 3-Wing, Low M6 Hand Knob for Thule Roof Mounted Kayak Carriers - 753-0783" for my Mondial Car-Go 320. I simply had to drill new holes at 4" apart and now I will be able to install and remove the carrier with much more ease than the nuts and bolts I had to use before. Just had to do a little research on the sizing to make sure I go the correct parts. This should work great!

Dan H, how did this go for you? We have to drill new holes in our carrier and want to make sure we do it safely. thanks!Q

Lori - It went great. They are so much easier to use than the brackets we previously had. Makes putting the carrier on and take it off much easier and takes half the time.

Works well with my existing roof rack on my Highlander.


Item matched item description.


Excellent job thanks


I received a damaged envelope type package that only had three of the U bolts, the fourth must have slipped out somewhere on the way. I emailed etrailer on a Sunday and received a same day promise to ship out the missing U bolt. It arrived in a box instead of an envelope like the first shipment. It was stuffed with packaging and the box was taped up very well. They obviously wanted to make sure the bolt wasn’t lost in the mail again and I appreciate it. I’m very happy with the customer service and will order from them again.

I got an email from etrailer asking for a followup on the last day of a trip from Houston to New York and back and the U-bolts held up perfectly. I didn’t have to tighten or adjust them at all for the entire trip and I never took the cargo shell off the roof for my 2 week stay so there was a mix of highway and in-town driving. These are great parts and etrailer has always had excellent customer service in my experience.

Great quality item. Has worked well for over a year.


We lost one of these on an older model of SportRack clamshell carrier. So happy this is the exact piece we needed. Fast response and shipping. Glad to find this site.

Still working great!

Easy to order. Delivery was prompt.


Quick delivery. Great customer service. I worked with Amy H. She was very helpful and friendly.

It’s been a year and it is still working as perfect as the day it arrived. Great company to work with!
Lauren - 05/04/2022


Very well made. Light but very strong. Easy to assemble.


Just as good as the original


I misplaced a specialized u-bolt for my Thule cargo box. After finding that I needed to purchase the entire hardware "kit" from Thule for $50 in order to get a $2 replacement piece of hardware, I instead contacted and got the u-bolt I needed in a timely manner for a couple of dollars. Customer service and follow-up for a simple piece of hardware was exceptional. Good people to do business with.

The cargo carrier with the replacement U-bolt have logged about 5000 miles with no issues.
Mark D - 06/27/2018


Great replacement from the nuts and bolts slider bracket. Pit these on a Sears XL 20 cargo and another set on Sportrack Aero 1300. Fit perfect on both. No redrilling holes, no resizing the existing holes.or metal plates.


Exact replacement for the mounting bracket I needed for my Sears XL Cargo rooftop carrier. The measurements provided on the Q&A section about the bracket were exactly correct and dispelled any concerns I had.

Yes. I’ve used it numerous times since buying the bracket and it has performed great.
Joshua - 10/10/2020


Right part right price


Perfect fit


Great, inexpensive, delivered promptly, and exactly as advertised... I will be ordering again from them as they were excellent! Saved me lots of money and got my older roof box up and running!

A year later going strong! 1000s of miles with no issues whatsoever in keeping our cargo box in place. No rust on any of the brackets even with extensive snow and salt exposure... thank you!!
