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.

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.

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.

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.

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!
Comments
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!

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.

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.

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.

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.

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.

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!

- 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.

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

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

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...
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...

- 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...

- Square U-Bolts to Use with CE Smith Axle CE 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.

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 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.

- 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 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...

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...
view full answer... - Replacement Axle Tube for a Habor Freight Model 90154 TrailerIn 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...

- 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...

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... - 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...

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.
