Just a bit disappointed in that the specs on this kit say that it is made for 2 3/4” leaf springs. The U bolts were not quite wide enough for the springs as stated on package. I ended up having to grind about 1/8” off each side of the leaf springs to get the U bolts to fit over them… shouldn’t be that way!

Solid square tube axle beam, and I love the EZ-lube axle spindles. Installed in literally minutes with zero difficulties. I used this to replace the axle (and hubs) on a Haul-Master 1195 lb. 4' x 8' folding trailer (from that ubiquitous store that sells cheap tools - you know the one). I wanted a heavier duty axle with hubs that are standard sizes and could be repaired with readily available parts should I experience a breakdown on the road. The spring center to spring center distance of 46-1/2" is perfect for this application. I installed my new axle without a fuss in about 5 minutes. New hubs took another 5 minutes, and the setup was perfect on my first 300-mile trip hauling my enduro bike to the trailhead.

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.

Ordered new axel and hubs to replace my bent axel on older utility trailer. Instructions for ordering the correct parts was clear and easy. It was shipped the same day as ordered. Arrived in record time in great condition. Good quality. Perfect fit.

I just wish they could be 1/4 tp 1/2 inch longer. I had a hard time in connecting to my axle. Got it done. Thanks.

by:

The product itself was good, however in my case the u-bolts ware to short to get full thread engagement or the lock washers. All I ended up using were the rectangle plates, nuts and washers. It would be nice If there was option to get longer u-bolts. The additional (longer bolts) and plates I had to fabricate, cost me more than your kit. I should have made all the parts myself. It still would would have cost me more, but the trouble I went thru would have been known up front. I will still use your company for other trailer parts, but I will now cautious. Rod

The u-bolt kit is designed for use with 1/2 square axles only. If used with the axle its intended for, they will fit perfectly.

Excellent product. The U-bolts fit the slipper springs nicely and were easy to install. I ended up not using the mounting plates as the plates welded to the existing axle matched the U-bolts.

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.

Needed to replace springs on a kayak trailer, this kit did the trick. The things we like best about etrailer are the specific descriptions and videos. All we needed were a few measurements and ordering the perfect parts was simple. Trailer is ready for another great paddling season!

Using this well described kit to rebuild my suspension was a great decision and it led to complete restoration of the whole kayak trailer. Better than new now!

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.

The parts are exactly as they were described online. I needed the square u-boots to attach a bike rack to my cars roof rack. Drilled out the mounting plates and everything works perfectly.



- CE23102
by:

etrailer was the only place I could find that had the exact replacement part for my trailer.



- CE23102
by:

Because the new springs are 4-leaf, the U-bolts are about 1/2" to 3/4" inch too short. Because they are too short, I'm not able to engage enough threads on the nuts to feel safe about tightening them. Unfortunately eTrailer doesn't carry longer U-bolts for 1.5 inch axles so I'll have to source them elsewhere. On the other hand, shipping was fast & customer support was very responsive.



- CE23102
by:

I used one of these to hang my 80 pound spare tire under my RV from a 1 1/2" bar that had a single bolt with stripped threads that held the tire previously. I couldn't believe the perfect fit including a hole for the stripped bolt. It made a very, very secure hanger. I used the original 1 1/2" bar to cross the large hub hole, just above the 4 hole plate. Love the thick steel plate and quality U bolt and nuts and lock washers. Beautiful permanent solution. Thanks etrailer!

This was one of the few places I could find the exact piece I needed. Everything came quickly and installed and worked as expected. Great place to deal with have ordered several thing over years.

Worked real well and seem to be real good quality material. I would buy them again if needed again.

    The 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.

    What 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.

    Thanks 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.

  • 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.

    I 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 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 # SP-124275 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...

  • Replacement Axle Tube for a Habor Freight Model 90154 Trailer
    In order to determine if we have a new axle beam that will work for you, we would first need to do some measuring. The measurements that will need to be taken are from the center of each spring seat on the axle you have now as well as the distance between the two hub faces. I have attached a photo of this for you as well. The most important measurement that you need to verify is the hub face as the spring seats can be moved. For example, if you have a hub face of 60" you can then use...

  • Removing Square Axle from Leaf Springs to Replace Axle on 5x8 Trailer
    On 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.

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.
