Video Transcript for Replacement U-Bolt Kit for Blue Ox Weight Distribution Spring Bars Feature Review

Ellen: Hey everybody, I'm Ellen here at etrailer.com, and we're taking a quick look at the replacement hardware for your Blue Ox spring bar. If something happened to that original hardware, maybe it got rusted out, or damaged, or bent, or something else happened to it, and you just need this hardware to replace, this is going to be a great way to do it without having to replace the entire unit. I will say, though, if your weight distribution went through something like a crash, or some other kind of catastrophic failure, it's probably a good idea to get a whole new replacement. But again, if just the hardware is bad, everything else is fine and is up to code and all that good stuff, then this is going to be an easy way to fix that hardware.It's going to come with everything you see laid out on the table here; I'll go over those parts with you. We'll get our two U bolts; these are going to be 3/8" bolts, and then we'll have our locking 3/8" nuts to go with that, and also the fender washers, one for either end. As far as the size of the nut, to take it off, it looks to be about a 1/2", maybe about 9/16", actually, to get that off.

The distance of the U bolt, or the total length here, about 2". Distance in between the two posts is about an 1 1/4", just to give you some reference points, in case you're not using this for the same application, maybe you want to use some of it for someone else, just for reference.That's pretty much it for a quick look at the replacement U bolt kit for your Blue Ox weight distribution. I hope this helped in deciding if this is the right replacement part for you. We do have a lot of other replacement parts for Blue Ox, and all kinds of accessories for your towing-weight distribution needs. Check us out right her at etrailer.com.

Thanks for watching.

Back Ordered parts came a month earlier than you said they would. I like that. They came before the next two.

Another 10,000 miles its time to rotate the u-bolts so the chains wear at a different place. Allowing wear making diameter of u-bolts section less requires changing. Failure would cause unwanted yaw inputs.



by:

Exact OEM replacement for my existing worn u-bolts. Timely delivery. Fair pricing.



by:

Timely delivery, exactly what I needed.



by:

E-Trailer always responds immediately and know how to solve my problem.

Bravo to the Blue Ox System. Gives me confidence pulling my Airstream. Could not be more satisfied. Truly!



by:

Although we haven't used it yet...it is exactly the part I needed to replace. The ubolts on my arms were bent pretty badly. Searched everywhere to buy them for my mechanic to install. Nobody sells these. Had to order on etrailer.com. agent was very helpful and product arrived on time! I recommend etrailer.com for any parts tou need for any blu ox unit! We will be taking trailer out this weekend and have every confidence in this product.



by:

Great customer service and quick delive ry.



by:

The go-to site for camper trailer parts. I had checked locally at our three major hardware stores, but U-bolts were not in stock at the necessary weight.
The online video was exactly right for clarifying that I was ordering what I needed to replace U-bolts that were damaged by a bottoming-out. Keeps my weight distribution spring bars in order.
Exactly what I needed, easy to get, third buy from etrailer.



by:

Perfect fit and exact match.



by:

Received quickly and fit perfectly...packaged and shipped safely....



by:

Great quality. The threads are a little bit shorter than the original, but I don’t think it will matter.



by:

The product was exactly what I needed! After buying a couple of products that were labeled as what I needed, which were too small, including an incorrect recommendation from Blue Ox, I was very frustrated and reached out to etrailer. I was contacted by Sierra who was very concerned and persistent. We worked together and she found the right part. She definitely went above and beyond.

It’s working out perfectly. It was a matter of finding the right sized product and etrailer put in the extra effort it took.



by:

Parts showed up as expected and were easy to install.

very well



by:

Appreciate the prompt service and happy that you had exactly what I needed. These were replacements for a 5 year old Blue Ox weight distribution hitch that I was refinishing. Fair amount of rust and bolts were also stripped after I removed the old nuts. Glad that these were available.



by:

Weaker steel than original. Broke while driving after about 6 months of daily use. The spring bar put a big gash in the road.

I reached out to the manufacturer and if the u bolts break then it is typically from the system bottoming out or having too much tongue weight for the bars to handle.



by:

It's almost impossible to find U-bolts in grade 5 or 8.
I'm cleaning up a Blue Ox Sway pro and cut off the old bolts.
So, finding the kit at a reasonable price was a no brainer.
I degraded one star because the washers don't appear to be grade 5.
I'll get some at Lowe's.
I'm happy.



by:

Wanted to paint the weight distribution bars and replace the U-bolts after four years of use. Had no success finding comparable U-bolts at local hardware and auto parts stores. Checked the etrailer site and found exactly what I needed. The customer service and delivery was great and efficient!



by:

Replacement U-Bolts for our Blue Ox trailer hitch were an exact match, with everything needed. Very quick shipping!



by:
