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..
very nice piece
Fast shipping. Great product
Great product. Perfect fit. They are a really solid and quality part.
These are heavy duty Ubolts. Just what I need.
Very Heavy duty and exactly the right size for my new 1 1/2" axle
after searching for days they had just what I needed and was at my house in 2 days. really happy with it.
I had tried to buy these locally but did not succeed I was told they would make them at 4 times the price, the product was high quality and just what I needed at a great price and right on time,
My only problem is that I didn't check the threaded lenght I needed, these were not threaded far enough for my application
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.
U-bolts and plates will be used to fabricate guide posts for my boat trailer. Great product !
Shipping was fast and the product is exactly what I was after. The web page did a good job of showing the product. My experiance with your staff was also excellent. I would defiantly order through you again. Thanks and Aloha.
Worked great could not find them anywhere in town
Perfect fit for hard to find axel bolts
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!
Fit perfect! Exactly what I needed!
As expected!!
Excellent product and hard to find. The shipping was super fast which allowed me to finish my project fast!

Trailer still holding up.
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
Perfect and quick delivery great product and great service.
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!
