Big trailers need parts that don’t flex or twist under pressure. This U-bolt plate is made for serious weight, fitting 12,000-lb to 15,000-lb Dexter axles. It uses 3/4" diameter U-bolts (sold separately) to clamp the axle tight to 3" wide leaf springs so everything stays securely in line mile after mile.
Getting the right fit matters when you’re tightening down your suspension. This plate is made specifically for round axles with a 5" diameter and pairs perfectly with 3" wide leaf springs. The geometry is spot-on so the U-bolts seat squarely and hold firm without distortion or uneven pressure.
Built with strength in mind, the plate measures 9" long, 6" wide, and 1" thick. That kind of size and thickness gives your suspension a rigid mounting surface that won’t bend or warp under load. It’s the kind of hardware you install once and trust to stay put through years of hard use.
This plate is designed to work with (2) 3/4" diameter round U-bolts (not included). The straightforward layout makes it easy to bolt everything together securely so your axle and springs act as one solid unit. It’s a clean, no-nonsense solution that keeps your suspension tight and reliable.

Speaker 1: Today we're taking a look at a U-bolt plate for five inch diameter round trailer axles with three inch wide springs. This is used with U-bolts to secure an axle to lee springs, which are mounted to the trailer frame. This unit's made from a durable steel construction that attaches with two 3/4 inch diameter around U-bolts, which are sold separately. They're available at etrailer.com. When it comes to the dimensions of this U-bolt plate, edge to edge going this direction, we're looking at about nine inches. Edge to edge this direction is about six inches.
Top to bottom measures about one inch. Now this is designed to fit round trailer axles with a five inch diameter. We can tell that by taking a measurement from the closest point of one hole to the closest point of the other going straight across. So we can see that that space right there measures about five inches, so that's the five inch diameter axle. And then side to side this way we can see that it works with three inch wide lee springs, again, closest edge of one hole to the closest edge of the other, that's three inches right there.
Now this fits round trailer axles with a five inch diameter and it is designed for use with 12000 pound to 15000 pound Dexter axles.That's gonna do it for today's look at the U-bolt plate for five inch diameter round trailer axles with three inch wide springs.

Excellant product quality and communicatiion. Fast shipping. I have made several orders from ETrailer and all have been great.
Easy to find online. Quick shipping, Perfect fit, Will do business again
Product arrived quickly and accurately content wise. The hangers are going to be tight fit on 1 3/4 wide springs (weld on and spread a little).
I immediately ordered from etrailer again as I only ordered 2 u bolts rather than the 4 necessary.
THANKS ETRAILER FOR YOUR ONLINE PRODUCTS ON MY ORDER
1 Year in and still working flawlessly. Put around 2500 miles on the boat trailer since they have been installed.
exactly as described
My entire axle assembly turned to rust. I rebuilt the whole thing. I metal prepped and painted including mating surfaces.
Nice parts
The plates seem to be made well. I haven't had time to install them. So im hopeing they fit well. Shipping was poor through the postal service. They were supposed to be here on 9-2 but dident show up until 9-8. But I know you guys can't control Shipping. The product seems to be made well.
