Today, we're going to be taking a look at a replacement U-bolt with nuts for 1 1/2" wide square trailer axles. You would use the U-bolt with a U-bolt plate and an additional U-bolt with the same dimensions to secure an axle to the leaf springs, which are mounted to the trailer frame. This is going to feature a threaded portion on each end. That threaded portion measures about 2" on each side. If we put a ruler on that, you can see that the threaded portion, from the bottom of the post to the top of the thread, measures 2" long. This is designed to fit a square 1 1/2" wide trailer axle. It is for 3500 pound axles only.
It's going to come with the included nuts. The opening is going to measure about 1 1/2", so that's how we can tell it's for 1 1/2" wide trailer axles. The bolt diameter is 1/2". The length from the bottom of that portion, there, to the end of the threaded area is going to measure 5" long. Then, again, that opening is going to give us an inside width measurement of 1 1/2". That's going to do it for today's look at the replacement U-bolt..

I looked all over for a u-bolt to replace one that broke on my 70's era horse trailer. I was about to give up when I found an exact match on etrailer.com. These shipped fast, were packaged well, and are just what I needed!

Working great ,,no complaints. ....
I ordered 4 square u-bolts and 2 plates as part of replacing the axel on a 1977 small boat trailer. Needed longer u-bolts than I fond any place else, but trailer had ones that could work. Ideally would have preferred stainless or at least galvanized for use in salt water, but at least could get trailer back on the road. 1 of the 4 u-bolts I ordered was narrower than the rest, had to be forced on at risk of damaging the threads. The center hole in the plate was too small to fit over the top bolt head on the leaf spring; so had to resort to under slung install - which was not the original trailer setup.

I will have our customer service team reach out to you. I would recommend using a corrosion resistant spray with the u bolts and plate. When using in salt water then rinsing off the u bolts and plates with freshwater will help to length the life of the parts.
Excellent product and hard to find. The shipping was super fast which allowed me to finish my project fast!
Very happy with the great product, great price, as well as fast, fair-priced shipping. Will definitely use etrailer again when the need arises.

I sold the trailer that this part was installed, but the installation went smoothly, and I was happy with my purchase.
My etrailer.com parts fit exactly to the specifications needed for the little green trailer I was restoring. Thanks etrailer.com for having some difficult to find parts available for my project. Shipping and communication was excellent as well.
I have a1962 camp trailer that I wanted to reverse the axle
I searched through my city, and was not able to find square U bolts
I went to our”Trailer” expert business and was told they not linger carried 1 1/2 bolts, they referred me to a speciality spring shop only to find he did not have the capability
I finally look online and found that Etrailer had in stock
I will now go to Lori at Etrailer 1st
Haven't installed them yet but they look perfect—the videos on you site are extremely helpful, but it would be even better if you suggested this product any time someone browses or buys a set of 1.5" wide leaf springs (ideally you'd suggest both this product and the U-bolt equivalent to cover both folks with square and cylindrical axles).
Thanks again for your excellent service!
Used this to mount tail light brackets on my old M101-A2 trailer. Fit like a glove around the framework.
We are working on a vintage Shasta travel trailer. We were thrilled to find a very necessary part . 2 U-bolts ..the RIGHT size. E-Trailer were very helpful in filling our order. Clear, concise and prompt delivery. We will use them again.
My experiance in dealing with etrailer could not have been beter. they were frendly, new there products and got me the right kit for the trailer I was working on. The quality is very good.
Quality Bolt. I will use Etrailer again. I could not find these bolts locally mainly because I work six days a week and the parts suppliers in the area only work five.
This made Etrailer a awesome option. Price was the same as the local suppliers and I had the parts in four days allowing me to finish my trailer without having to take time off from work to chase parts, another added savings. Thank you Etrailer.
Exactly what I needed to fabricate two mounting brackets to attach the canopy I built for my Kubota.
Thanks!
Fit perfect for an older trailer with 1.5 in axle and 1.75 leaf springs. Exactly what I was looking for. Thank you etrailer!
I sent for 4 ubolts for my horse trailer because etrailer was the only one who had the right size . I ordered them overnight and they came at 12 so o had time to put them on the next day .
I put them on they fit they were the ones I ordered so o saved $680 by using my own trailer and not needing to hire a hauler .
I’m extremely happy with my purchase and the speed it got here so I give 5 stars because you guys earned them .
Thank you
I’d do business with you again in a New York City second !
Exactly what I needed.
Arrived quickly.
Trailer still in use.
Should outlast the old trailer I put them on.
I couldn't find the proper size at any stores near me, found them at "etrailer" at a great price with reasonable shipping and received them a day earlier than expected, they fit perfectly, definitely will keep "etrailer" in mind for future projects
product is very high quality and will more than likely last the life of my boat trailer. i'm very pleased with product,thank you.
It is hard to find U-bolts to fit older camp trailers (1969) But these U-bolts from etrailer were well made and fit perfectly-thanks.
Product is high quality and as described on etrailer.com. Extremely happy with purchase. Will definitely visit site again.
U-bolts and plates will be used to fabricate guide posts for my boat trailer. Great product !
This went very well. The parts were exactly what I needed and I received them when promised. In addition, the web site detail for the parts was great as I was able to order the parts to 3 critical dimensions as clearly displayed on the web site. Thank you so much.
First off, the bolts fit a 1/12 axle with the kind of snugness that promotes confidence..
They are accurately made, and fit my suspension well.
Do you have a question about this Trailer Suspension Part?
