Keeping the axle tight to the springs is what keeps the suspension working right. This U-bolt plate is built from zinc-plated steel that meets ASTM specifications, giving you the strength and corrosion resistance needed for long-term use. It’s made to take (2) 1/2" diameter U-bolts to secure your 2-3/8" diameter round trailer axle solidly to 2" wide leaf springs.
Moisture, salt, and grime can wear down bare steel fast. The zinc-plated finish on this plate keeps rust at bay so your suspension hardware stays solid even after years of use. It’s a dependable way to keep the suspension together and the axle locked in place without worrying about corrosion eating through your parts.
When you’ve got to mount or replace suspension parts, straightforward hardware is best. This plate is designed for standard 1/2" diameter U-bolts, so you can pair it easily with matching hardware to clamp your axle down tight. No custom fitting or guessing—just a clean, strong connection that does its job every time.
A well-secured axle makes for a smoother, more predictable ride. This plate keeps your 2" wide leaf springs and 2-3/8" round axle properly aligned so the suspension moves the way it should. It helps reduce sway and bounce by keeping everything locked in place, giving your trailer a stable, steady track mile after mile.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this U-bolt plate. Now, this plate uses two 1/2-inch-in-diameter U-bolts, which are sold separately, to attach your 2-3/8-inch-diameter trailer axle to your 2-inch-wide leaf springs. Let me go ahead and give you some overall dimensions. So looking at the length first, looks like we're sitting right at 5-7/8 inches long, the width right at 4 inches.
And let me go ahead and pop a diagram up on the screen there for you. That's going to give you additional measurements that you might be looking for, and that's gonna be a little bit quicker to show you through that diagram than just putting a ruler up to all the other areas of this plate. So hopefully that's gonna prove helpful for you if you needed those measurements. You can find this diagram on this product page as well if you need to refer back to it. This is constructed of zinc-plated steel per ASTM specifications.
I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Just what I ordered heavy duty
The distance between the holes do not match the U-Bolts.. only a couple mm off... but off.. I am underwhelmed as I specifically asked if they would work.
I had to drill out the holes to make them bigger as the U-Bolt doesn't fit correctly as-is. Hard to show in pictures but I think you can see the issue.
I tried to upload the pictures but they would not upload so I am emailing them separately.
Fortunately, drilling the holes bigger seems to have solved the issue, but that really should not have been necessary, especially as I double checked that this plate would work with these u-bolts.
U bolts and base plates were thicker than OEM and installed flawless
Good products and great pricing...
Worked just fine, very happy.

Product exactly as described and good quality.
It was just a described and shipping was fast. I had both installed on my axle within under 30 min.
Fast shipping and exact fit for what I need. Not to many places out there that had what I needed .
Thanks.
These U-bolt plates worked perfectly to secure the trailer axle to the frame. I have driven the trailer both on and off road on many occasions and have seen no sign of irregularities. Highly recommend but also make sure to measure twice before you order.
E trailer had just what i wanted. It was hard to find a u bolt plate for a 2 inch spring. I called Bill in the parts department and he checked to make sure he had it in stock. That is great service. I had the part in 2 days. Thank you Mike S.

The U-bolt plate is working out great. Your parts department did a great job.
Heavy duty plates. Better than I expect ed.
The zinc plating is very thin compared to the zinc plated u bolts I order with these plates other than that they are as described.
