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.etrailer has always had what I needed when no one else did. They are my #1 source for any of my trailer needs.
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.
Worked great fast shipping
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.

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.
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 - 04/07/2020what can I say, it works.
Michael O - 03/27/2021Excellent quality. May have to adjust for length. would like to have more variety in assortment. Over all rugged and will get the job complete :)
I 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.
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
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.
Great product
Rebuilt trailer suspension, should be good for another 20 years. One of my old springs snapped.
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.
Products were as advertised. Easy to use due to the quality of the parts . I will use etrailer for all my trailer needs and let my garage buddy's know of etrailer also
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!
Happy with this.
Ordered these for my boat trailer,I use them to attach cradeles to it to hold my Hobie cat boat,they fit perfectly.
One year later and no signs of rust. Used on a boat trailer. Fully submerged in salt water multiple times. Great product!!!
The U bolts fit fine and worked perfect! Go Gatos!!!
After a long search, etrailer had exactly what I needed. Delivered when promised.
Monty - 05/12/2017Identical replacement for the rusted u-bolts I broke while repositioning bunk.
Matched what came off the trailer. Don't forget nuts and anti-seize. Suprised how fast it was delivered considering it was by ground transport.
Excellent product, very quick delivery! Will shop here again and recommend entrailer to friends!
