When suspension parts start to flex or loosen, the whole trailer feels it. This U-bolt plate locks a 1-3/4" diameter axle to a 1-3/4" wide leaf spring for a firm, reliable connection. It’s built for 3/8" diameter U-bolts (sold separately) and has a 7/16" bolt hole diameter to match tight. The 3-1/2" overall length and 3" width give a solid footprint that spreads the load and keeps the hardware from shifting under stress.
Salt, water, and road grime eat away at bare steel fast. This plate is made from galvanized steel that’s hot-dipped in zinc for a thick 3-5 mil coating. That layer seals out rust and holds up through years of wet conditions, making it ideal for gear that sees water or snow. Once installed, it keeps the suspension hardware looking clean and solid, even after repeated dunkings or long storage.
On small trailers, every pound of capacity counts. This plate is designed for setups rated around 2,000 lbs, giving dependable strength without adding bulk. Its clean, flat design fits tight under the spring pack and keeps the assembly compact yet sturdy enough for steady towing.
Getting the axle and spring to line up can be the hardest part of a suspension job. With 2-1/4" and 2" center-to-center hole spacing, this plate takes the guesswork out. The holes are precision-cut for 3/8" hardware, so once the U-bolts are in place, everything cinches up smooth and square for a no-hassle install.

Today we're going to be taking a look at the CE Smith U-bolt plate for trailer suspension systems. The U-bolt plate is going to help secure a 1-3/4 inch diameter axle, so a 1-3/4 inch wide leaf spring. This unit is going to require two 3/8 inch diameter U-bolts. Those u-bolts are sold separately, but the four outer holes on the unit are designed to accept 3/8 inch diameter bolts. The unit is made from galvanized steel, so it's very strong and durable. It's going to do a great job at resisting arresting corrosion, making it great for use on boat trailers or any trailer that's exposed to moisture.
The product's made right here in the USA. A few measurements to go over with you real quick starting with the overall length, it's going to measure 3-1/2 inches. Now the holes right here, these are going to be separated on center from one another by 2-1/2 of an inch. The overall width, that's going to give us a measurement of 3 inches and then those holes are going to be separated apart from one another on center by 2 inches. That's going to do it for today's look at the CE Smith U-bolt plate for trailer suspension systems.

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.

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
