A loose or shifting axle can ruin your ride quality. This CE Smith U-bolt plate gives you a solid, reliable clamp point for your axle and springs. It’s built to work with 3" diameter round axles and 1-3/4" wide leaf springs, holding everything in place so your suspension stays tight and tracks straight mile after mile.
Getting your suspension hardware lined up cleanly makes the job go faster. This plate is drilled for 9/16" diameter U-bolts (sold separately), giving you the right fit without guesswork. The bolt holes are spaced 3-1/16" apart from inside edge to inside edge, so the U-bolts slide in perfectly and clamp down evenly across the axle.
Thin plates can bend under load, but this one doesn’t. The 7/32" thick steel tie plate adds strength to your axle connection, keeping the assembly rigid and balanced. At 5-7/8" long and 3-3/4" wide overall, it spreads the clamping force evenly across the leaf springs for a secure, lasting hold.
Whether you’re replacing a damaged plate or setting up a custom suspension, this single U-bolt plate makes it easy. Just match it to your 3" round axle and 1-3/4" springs, add two 9/16" U-bolts, and you’re back on the road with a clean, sturdy connection.

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at this U-bolt plate. Now this U-bolt plate uses 9-16 of an inch diameter U-bolts that are sold separately from this plate to attach your 3-inch-in-diameter trailer axle to your 1-3/4-inch wide leaf springs. So let me go ahead and retrieve my ruler here, give you some measurements that might prove helpful for you. So looking at the overall length, we're sitting right at 5-7/8 inches long, the overall width is gonna be 3-3/4 inches wide, and then this might be a little trickier, I'm gonna come around the table here so I can see as well, but I first want to give you the measurement of the length of the holes, and I'm gonna be measuring this in between the holes rather than on center.
So in between the holes it looks like we're sitting pretty close to 3-1/16 inches, and then looking at the width in between those holes, finding that up there, we're gonna call it right at 1-11/16 inches, so hopefully that's visible to you and helpful to you. Again, the bolt-hole diameter is 9/16 of an inch, but if you happen to have any further questions about this U-bolt plate or any of the other U-bolt plates that we carry, or the 9/16-inch diameter U-bolts that this uses, don't hesitate to reach back out to us. We do wanna be sure that you're getting exactly what you want and need. Well, that's gonna wrap up our look today. I do hope that it was helpful for you.
Again, my name is Andy. Thank you for joining me.

This plate is not sturdy at all plate was bending when tightening and axles were shifting
Completely restored our 1987 8x 10 trailer, turned out great. I found all the required parts from etrailer. Shipping was fast. etrailer was excellent to deal with. Thanks etrailer, best regards
Good product. Works good for me. Quick shipping.
Good product.
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.
Outstanding product, delivery time, product cost, and above all, communication. 5 star company!
Fast service always have what you need
I looked all over and no one had these it seems that everybody had 2 inch. My boat trailer is an older one probably from the 1970s with a1 3/4 axle not that common anymore. Thanks etrailer just what I needed.
All is well
Good product with zinc oxide coating to resist corrosion. I would give this product a better rating but truthfully, it needs to be thicker to resist bending when the 1/2-13 u-bolts are tighten to recommended torque specifications.
etrailer is Amazing...Great customer service always reaching out to make sure your satisfied...My order was quick and easy to order
Great parts fast shipping
Excellent quality
Fit perfectly and as advertised. Replaced my stock leaf spring plates on fifth wheel RV which were too wide to accept the SumoSprings trailer helper springs. Easy install.
Heavy duty and good galvanized plating
The two plates were joined together and appear to have been dipped together and could not be separated. Trailer has sent out replacements immediately
Exactly what I needed, couldn’t find it anywhere else. Super fast transaction and shipping
I’ve placed a lot of orders , everything is always as advertised and I can’t believe how fast they ship it
