every thing worked fine the only problem that i had was the u bolts needed to be about 1/2 inch longer. i could not use the lock washer's
by: James07/23/2022
This kit worked well for mounting 1 1/2" guide-ons on my trailer but they are not going to last long for my salt water application. Only the plate (which I didn't use) is zinc plated. The U-bolts, nuts and lock washers are plated with something but they are not zinc plated as indicated in the description.
Comments
I had the u bolts pulled from the warehouse so that I could take a look at them. The u bolts that I saw still had the zinc plated finish.

This was second time I purchased a trailer axle from etrailer. Your website is excellent for both getting the right part and installing it correctly. The parts were reasonably priced, excellent quality, and were shipped fast. Thank you!
by: John05/23/2022
The U bolts were to short. I asked for help from your company. I got thank d for asking a question but received. No help. As it turns out I had to go to a local spring shop and get U bolts I can use. If you’re going to have a help line. Maybe they should actually try to help
Comments
I am glad you ended up finding what you needed. For future reference, you would need to get measurements of the width of the axle and the leaf springs. Part # SP01-120
1-1/2" Square Trailer U-Bolts (Qty 2)
$19.43 is similar to this one but the U bolts are taller.

The quality and workmanship seems fine on these. The width of my leaf springs caused the u-bolts to be slightly canted but no big deal. 9All is good and these worked great to attach my replacement axle to my old trailer.
by: Cory07/07/2016
Just ordered another set. Build my own axles with spindles and hubs from e trailer along with 1 1/2 " square tubing. This u bolt kit is complete and the best price I have found. Picture wont show the u bolts but it will show you what I do with them.
by: Amy08/06/2022
This was the exact replacement for my kayak trailer suspension. It’s been in use for a year — so far, so good!
by: Marshall04/22/2022
I ordered this U-bolt kit to replace aged and rusted parts on the original trailer. I am happy with the quality of the plates and U-bolts. Keep in mind that you only need to order ONE (1) kit per axle.
by: Brad07/16/2020
My old u bolts and leaf springs were rusted through so bad I had to cut them off. I had such a hard time finding replacement parts for my little boat trailer with such a small 1 1/2 inch axel. This was exactly what I needed! Fit perfectly with my New 24 5/8 x 1 3/4 inch leaf springs.
by: Andrew05/20/2022
Seems to be good quality. Just installed them to replace some poor rigging by the person who owned the trailer previously.
I will change the nuts to neoprene locknut. I like they are made in the USA
Thanks
by: Darald05/26/2019
They worked great. Replaced my old rusted axle brackets with ease. And for a lot less than what the local trailer shop wanted to charge.
by: Ryan10/15/2022
Quality shipping and communication. Will do business with again!
by: Chubb C.07/30/2022
We had looked everywhere local for these ubolts. No one had them. Thankful to find etrailer online. These are a perfect fit. Exactly what I was looking for
by: Russ07/27/2017
Ordered early Friday morning before business hours. Parts arrived the following Wensday afternoon via UPS.
The only concern I had with the two springs I ordered was the cheap nylon bushing they came with. I would have preferred neoprene but the springs were stamped made in China so......
Springs and hanger kit I ordered went together and look good.
by: Robert09/01/2022
Not as robust as the origionals but will do for me the trailer will not see nearly it's load limit

Just what I needed for and old sail boat trailer! Couldn't find anyone else with 1-1/2" axle hardware!!
by: Scott L.12/08/2017
Replaced rusty springs on a 14' skiff trailer. Fit perfect, DIY for cheap in the driveway, it would've been easier with an impact wrench. Take their advice, etrailer is the best for a reason, get ALL NEW HARDWARE TOO!! I broke several fasteners removing them, if the springs are bad, so is the hardware. I have done three hitches and a set of leaf springs now with these folks. Their install videos and expert advice made it a breeze to save probably a couple thousand in labor at a shop.
by: Lucas 02/13/2021
Hard to find product, needed for 2 old axles that had very rusted hardware. Fit perfect and has held up just fine.

I used etrailer during my restoration of my 1965 Travler Comet runabout boat. The trailer was in poor shape requiring all new suspension and hardware. etrailer had everything I needed. Easy to find and order. Great service and quick shipping.

See what our Experts say about this CE Smith Trailer Leaf Spring Suspension
- Thread Length of the U-Bolts of the CE Smith U-Bolt Kit CE23102I spoke with my contact at CE Smith and he informed me that the threaded portion of the U-bolts of the # CE23102 are 2-1/2 inches in length.

In other words it comes with two sets and not just one like you asked.

view full answer... - Replacement Leaf Springs and U-Bolt Kit for Small Boat Trailer with Square AxleWe definitely have replacement suspension parts for your light boat trailer. Attached is a link to our selection of leaf springs for a 2,000 lb trailer axle. These are 3 and 4 leaf springs and to select the correct one you'll need to measure the distance from the center-eye to center-eye of your current leaf springs when the load is taken off of them. For a U-Bolt kit it looks like the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles # CE23102 will fit the bill. Attached is...
view full answer... - Dimensions Of The CE Smith Ubolt Kit # CE23102The CE Smith U-Bolt Kit for Mounting 1-1/2 inch Square Trailer Axles - 3-3/8 inch Long U-Bolts - Zinc # CE23102 is 3-5/8 inches long, and the thread length is 2-1/2 inches in length per the manufacturer. I attached a review link video below.
view full answer... - Replacement U-Bolts Compatible with CE Smith U-Bolt Kit for 1-1/2 Inch Square AxleThe CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles - 3-3/8" Long U-Bolts - Zinc # CE23102 unfortunately doesn't have direct replacement parts outside of the kit. The Replacement U-Bolt with Nuts for 1-1/2" Wide, Square Trailer Axles - 1/2" Diameter # 1753223 is the closest we have to what you are seeking but it is not zinc plated and is 5 inches long.
view full answer... - Removing Square Axle from Leaf Springs to Replace Axle on 5x8 TrailerOn square axles, there is traditionally a hole that the leaf spring has a nub that fits in to act as that securing point that a spring seat on round axles would and then the u-bolts secure the axle to the springs. You can see this on the CE Smith Trailer Axle Beam with EZ-Lube Standard Spindles - Galvanized - 57-1/2" Long - 1.8K # CE33201GA and photos on part # CE23102. There is often a need once the u-bolts are removed to use direct downward force or even a pry bar to separate the springs...
view full answer... - Compatibility of 3500 lb Double Eye Springs on 1-1/2 Inch Square Trailer AxleThe 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/8" Long # SP-212275 would be a little firm if you are hauling the trailer without a snowmobile, but with one or more it would be fine. The additional weight capacity of the spring will not enhance your trailer's overall capacity. This is because you would still be limited by the weakest part of the system very likely your axle. I recommend using the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles - 3-3/8" Long...
view full answer... - Recommended Jet Ski Trailer Leaf Spring U-Bolt Mounting Kit for 1-1/2 Inch Square AxleRecommended U-bolt Kit for square 1-1/2 inch axle and # SP-113275 springs is the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles - 3-3/8" Long U-Bolts - Zinc # CE23102. This will work much better than the u-bolt that is simply used diagonally in your current photos. These are plates are galvanized and the hardware is zinc plated so they are ideal for your Jet-Ski trailer as they resist rust and corrosion.

- Square U-Bolt Kit for Mounting Leaf Springs SP-177275 to 1-1/2 Inch Square AxleYou have done your homework because you are on the money with the correct U-bolt kit to mount the 2-Leaf Slipper Spring w/ Radius End for 1,000 lb Trailer Axles - 24-5/8" Long # SP-177275. The kit you mentioned, the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles # CE23102 will work wonderfully for this application so you're all set. I have added links below to video reviews of both products as well if you'd like to check them out.
view full answer... - Replacement Leaf Springs and U-Bolts For Karavan 1,000LB Single Square Axle Boat TrailerThe 2-Leaf Slipper Spring w/ Radius End for 1,000-lb Trailer Axles # SP-177275 are going to be the closest to what you have. Depending on the exact location your red string in relation to the end of the radius spring this may account for some of the difference in the measurements. You do appear to have plenty of clearance in your fenders if the springs are not as tall. Be sure to not reuse your current U-bolts as they appear to be for a 2" axle. The CE Smith U-Bolt Kit # CE23102 is specific...

- Recommended Options for Height Adjustment on 1,800 lb AxleYou can mount the CE Smith Trailer Axle w/ Idler Hubs - 5 on 4-1/2 Bolt Pattern - 57-1/2" Long - 1,800 lbs # CE33201GA-HUB in an overslung axle position. You will simply need to use a U-bolt kit like # CE23102 but with longer U-bolts. We unfortunately do not have that hardware but you will want the bolt plates for 1-3/4 inch springs.
view full answer... - Can Round Trailer Axle be Replaced with Square Trailer AxleYes, you can replace a trailer's round axle with a square axle as long as the weight capacity is appropriate. You will need a new U-bolt kit to connect the axle: 1-1/2 inch square axles # CE23102 1-3/4 inch square axles # 175130 for the U-Bolts and # 116308 for the plate 2 inch square axles # CE23103
view full answer... - Square U-Bolts to Use with CE Smith AxleCE Smith has a u-bolt kit part # CE23102 that was designed to be used with their axle part # CE33201GA-HUB that you referenced. This is the correct square size U-bolts for this axle.
view full answer... - Are Trailer Spring Seats Needed for Square Axles with Leaf Springs?Square axles normally don't have spring seats like a round axle but do have a hole for the leaf spring bolt to fit into. Take a look at the CE SMITH # CE33201GA-HUB for a visual. The U-bolt mounting kits will have a hole in the center for the other side of that leaf spring bolt to keep everything in line. If you have a 1-1/2 inch square axle use # CE23102. If you have a 2 inch axle use # CE23103.

- Replacement Trailer Leaf Springs With A Reverse C Shaped End For A Boat TrailerThe closest option we have to your "reverse C" style slipper spring would be the 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles # SP-264275, which is 26-1/4" long. I recommend taking a second look at your current leaf springs and double checking the measurements to see if this will be a compatible fit. Since you'll be replacing your leaf springs I also highly recommend replacing your U-Bolts since these tend to bend and mold to the axle and are typically pretty hard...
view full answer... - Replacement Leaf Springs for Harbor Freight Folding TrailerThe best option we have for you is the 3-Leaf Double-Eye Spring part # SP-169275 with the Single-Axle Trailer Hanger Kit part # APS4. This option will replace the leaf springs and leaf spring hanger brackets which is needed because the new double eye leaf springs are 1-3/4" wide and the old slipper springs are 2" wide not to mention the length discrepancy and leaf spring hanger bracket height. The CE Smith U-Bolt Kit for Mounting part # CE23102 or part # CE23103 can then be used to complete...
view full answer... - How to Determine Correct Slipper Spring Replacement for 1,500 lb AxleWhat happens to slipper springs is that over time they elongate and flatten out, particularly if your springs are considerably older. The most important measurement you mentioned was the 26 inches from the center of the spring eye to the end of the spring. Based on that the closest slipper spring we have that could work is the 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # SP-178275, which would work if you had a tandem-axle trailer. There are no slipper...

- Recommended Slipper Spring for Custom Kayak TrailerThanks for the photos with measurements. The 2-Leaf Slipper Spring w/ Radius End for 1,000-lb Trailer Axles - 24-5/8" Long # SP-177275 are rated for 500lbs each for use with a 1000K axle. This will work with the inside to inside measurement you are seeking. You will simply need the 9/16 inch bolt # 166079. If there is any extra space in the hanger it won't be an issue with the bolt and bushing.

- Recommended 26 Inch Double Eye Springs for 1-1/2 Inch Square Axle CompatibilityThe 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275 are way to strong a spring for your 1-1/2 inch square axle. Typically 1-1/2 inch square axles have a capacity between 1000 and 2000 lbs. I recommend instead using the 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # e77SR which will match the standard capacity without making the ride too firm adding to bounce. Don't worry about the number or leaves but rather the capacity rating. I also recommend...
view full answer... - Replacement 1-1/2 Inch Square Axle for a Boat TrailerI do have some options for you but none of our trailer axles match the exact measurements that you provided. Therefore, the best option we have for you would be to switch to an axle less system like the Timbren Axle-Less Trailer Suspension System part # A20RS545 which will replace the axle, leaf springs, and leaf spring hangers in light of a rubber suspension system that works to absorb road shock and support the trailers load better than standard leaf springs. The other option you have...

- Switching From Slipper Springs to Double-Eye on a Single 2K Axle Trailer with Square AxleTo switch to double-eye spring suspension I recommend getting parts individually since the u-bolts cannot be swapped out of kits. The spring in the kit is # SP-169275. We have a few different u-bolt kits for square axles including # CE23102 for 1-1/2 inch square axles. For a 1-3/4 inch square axles you can use u-bolt # 175130 and plate # 116308. And for 2 inch square axles we have # CE23103. You will also need a new hanger kit since double-eye springs use different hangers than slipper...
view full answer... - Availability of 3 x 4 Inch Axle U-boltsAre you speaking of an axle U-bolt that joins the leaf springs to the axle? Is the width you mention the overall width of the U-bolt, or the inside width? We do offer a U-bolt kit similar to the # CE23102 kit you'd looked at. The # CE23103 includes 1/2 inch diameter U-bolts that are 4-1/2 inches long that have an inside span of 2-1/8 inches and an outside width of 3-1/8 inches as shown in the provided photo. CE Smith doesn't offer the U-bolts as a separate item, they're only available...
