Today we'll be reviewing part number UBZC12X212X525. This is Red Line's replacement U-bolt for 2-inch wide square trailer axles. It's going to act as part of a trailer suspension system. It's going to be used with another U-bolt. It's going to be sold separately as well as the U-bolt Plate, also sold separately, to secure one side of your axle to a leaf spring which is mounted to your trailer's frame. The square bolt is designed to fit square axle beams. Has a really nice zinc plated steel construction so it's going to be very heavy duty and corrosion resistant. It's going to be ideal for use on boat or snowmobile trailers.
One bolt is included with this part number. Again, it's designed for 2-inch wide axles. The inner width between the bolt posts is going to measure 2 1/8 of an inch. The length that we have from the bottom of the cross member to the bottom of the bolt post is going to measure 5 1/4. Then the bolts are going to give us a diameter of a half inch. The threaded portion on each bolt is going to measure right at 2 inches in length. That's going to do it for our review of part number UBZC12X212X525.
This is Red Line's replacement U-bolt for 2-inch wide square trailer axles.

This 5-1/4" long U-bolt works with a U-bolt plate and another U-bolt to help secure your 2" wide, square trailer axle to its leaf springs. Sturdy, zinc-plated steel resists corrosion.would be real nice if a couple of nuts were added to the u bolts, but readily available
Jenny N - 03/10/2022I ordered these a few weeks ago. Unfortunately the package was damaged in transit and the contents were lost. etrailer reached out and informed me they would send a new set. Arrived in a timely fashion but the second package was also damaged in transit but fortunately none of the U bolts fell out. Might package better for shipping but other than that, Excellent customer service!!!
Just as described and shipped the same day as ordered.
good quality . would be nice if it included washers and nuts.
etrailer has always had what I needed when no one else did. They are my #1 source for any of my trailer needs.
Excellent products fair pricing, supporting business in AMERICA and keep up the good work
Thanks
I bought springs, shackle bolts, and u-bolts and plates. Everything was great and fit perfectly. Only issue were the u bolts which were not galvanized. However, at a local trailer store, I bought galvanized U bolts for $4.50 each.
For the DYIers, taking the old ones off took more than 4 hours for each side. My existing shackle bolts were so heavily rusted that I had to cut three off with a hack saw. Difficulty was confined space to operate hack saw with boat still on trailer. However, reassembling the new springs was less than 45 minutes each side.
Must have tools are large diameter 3/4-13/16-7/8 deep sockets (6 point), 2 2 foot long breaker bars and a can of PB blaster.
For safety: Good quality jack stands, minimum of 3--don't rely on the front trailer jack as it may roll.
By the way, I did these myself and I am 64 years old.
These products are very difficult to find except at etrailer.com
They had the exact product: Square U-Bolts to fit a 4 inch x 2 inch framed trailer.
It's impossible to find these locally, (for me), but one stop at etrailer.com took care of my needs.
Excellent products. All were very well made. Very fast delivery. Extremely happy dealing with etrailer. Will definitely order from etrailer in the future. Also hard to find galvanized parts. Would refer friends to etrailer.
Johnny B - 01/23/2020I ordered several items for my boat trailer to replace the springs and renew the related hardware. There was a little glitch, as the springs were sold out in inventory. The etrailer staff quickly advised me of this issue and offered alternatives. However, my order was shipped was shipped within a few days and arrived as ordered. I will definitely use etrailer again.
Quick delivery, well packaged.
Exactly what I wanted to use on my tractor ROPS bar.
Will be back for more components for my next project.
John M - 04/07/2020Product worked perfectly
I ordered parts from etrailer.com before and this time the service was as good as the last time. Parts were identified very well and they fit perfect. Thanks again for the great service. I also found out that my son ordered his trailer hitch for his new Ford van from you and he says he'd do it again.
Thank you ,
Tom
Products are great and for a fair price. Be aware that the square u bolts have course threads and the nuts they sell for boat trailer u bolts have fine threads. I had to use some from a local store. Super fast shipping got me back fishing in no time!
High quality U bolts to mount a trailer tongue toolbox on my main beam of my trailer. Etrailer has many hard to find products & fast shipping & always great customer service. I use them fairly often. When searching for anything for trailers.....start here.
One year later and no signs of rust. Used on a boat trailer. Fully submerged in salt water multiple times. Great product!!!
Perfect replacement part fit and function no alterations were necessary and fast shipping. I replaced the worn out springs on my 1987 Skeeter boat trailer and was mad that I had not done it sooner. All the replacement parts fit perfect.
After a long search, etrailer had exactly what I needed. Delivered when promised.
Monty - 05/12/2017just wish you had a kit with these bolts along with nuts and lock washers. fit was fine.
Fast shipping only place I could find the right size I wasn't sure if it came with nuts and washer I don't see it in the description or the pic I got some for it any ways and the pic was right on but I would have like to seen it in writing to know for sure great service tho keep up the good work
Rebuilt trailer suspension, should be good for another 20 years. One of my old springs snapped.
So far so good.Right size and fit.I would buy this /these products again from etrailer.com.
My order arrived in the time frame projected. I was kept well informed of the shipment status. The items are very good quality and well packaged. I will order from etrailer again.
Fits like a glove.
