Average Customer Rating:  4.8 out of 5 stars   (324 Customer Reviews)

Mount your square, 1-1/2" wide axle to your trailer's leaf springs with this U-bolt kit. U-bolts, plates, nuts, and washers included. Zinc plating resists rust and corrosion - great for boat trailers.

by:

The u-bolts have stood up pretty well to the elements and strong enough to pull my full 2k pound trailer. So far so good with the zinc protection, hope it lasts as good as other finish options



by:

My order arrived as described and worked perfectly.



by:

They worked great. Moved the axle from above the springs to under.



by:

Fit around axle is good but bolts could stand to be at least an inch longer, only tighten up flush with plate under my 5 leaf springs, could not use lock washers had to use red Loctite.



by:

I did a complete overhaul and upgrade on my boat trailer. I put stiffer springs on and this bolt kit was a must have. e trailer was the only place that had enough inventory to get me the right size ubolt. Has been flawless in use.



by:

So far these have held up well. Been a year



by:

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:

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:

Looks Great !
works Great !
Thank
you,



by:

I was able to locate what I needed without a part number because of the efficiencies of your search engine and thorough description of the product. I’d been to a half dozen local locations before checking with you. Shipping was timely, so it worked out well, thanks.



by:

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:

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:

Wheel cut old ones off, installed 1 at a time to sucess !



by:

Looks to fit fine. I upgraded the nuts and washers to grade 8s.



by:

Good product fast delivery



by:

Good quality parts, easy to order and fast delivery.



by:

Made it easy to flip my axle and lower my 1956 boat trailer.



by:

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:

works good with leaf springs.



by:

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.

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 axle worked great on my trailer everything thing fit great

Works good



by:

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!



by:

Year after install still good



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.

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.

Products I purchased worked great!

  • Replacement Galvanized Square Tube Axle for 2008 SeaLion Boat Trailer
    We have something extremely close that will work for you. It is the CE Smith Trailer Axle Beam with EZ-Lube Standard Spindles - Galvanized - 57-1/2" Long - 1.8K # CE33201GA. It has the hub-face-to-hub-face length of 57-1/2 inches and the spring-center-to-spring-center length of 46-1/2 inches with the overall beam length of 62 inches. The only thing that you will need to change is the spring centers which is just a drilled hole for the square axles. There will be a difference with the...

  • 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. 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...

  • Recommended Jet Ski Trailer Leaf Spring U-Bolt Mounting Kit for 1-1/2 Inch Square Axle
    Recommended 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.

  • Recommended Slipper Spring for Custom Kayak 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.

  • U-Bolt Kit For Replacing Leaf Springs On a Trailer With Square Aluminum Axle
    While I do not see we carry any slipper leaf springs close to your measurements we do have a couple U-bolt kits for you to select from with having a square axle. We have a kit for 1-1/2" Square # CE23102 or 2" Square # CE23103 axles. I may be able to help you find a viable replacement leaf spring to go to double eye or another type of slipper spring but I will need some photos of your hangers along with any weight capacity information on your trailer or axle.

  • Do You Have A Suspension Kit With The 3-Leaf Double-Eye Spring for 2,000-lb Axles # SP-113275?
    We will not offer the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles # SP-113275 as a kit as there are so many different options for the leaf spring when mounting to the trailer. The spring will come with a Nylon Bushing # TRBU11566 already installed. You can replace this with a Bronze Bushing # D014-077-00 if you intend to mount the leaf springs using Wet Bolts # 126B2 rather than a Shackle Bolt # 166081. Next you will have different U-Bolt Kits depending on your trailer axle....

  • Replacement Axle and Suspension System For a Small Boat Trailer With 55" Wide Axle
    I have a couple options for you. First our closest axle to what you have is the CE Smith Trailer Axle # CE33201GA which has a hub face to hub face measurement of 57-1/2" so it will make the trailer wider. For leaf springs the 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles # e77SR are going to be our closest to your weight rating and length. This will require you to move your existing hangers to accommodate the new leaf springs. Finally you will need 2 Hubs # AKIHUB-440-2-G-EZ-2K, a...

  • Parts Needed For Adding 1,000LB Slipper Springs To a Cart With No Suspension
    You will need 2 of the Front # CE14016G and Rear # CE14017G hanger brackets to attach 2 of the 2-Leaf Slipper Springs # SP-177275 to your cart. You will need 2 of the Zinc Shackle Bolts # TRFA73Z916DLNZ to attach the leaf springs to the front hanger. If you can tell what shape and size axle you have I can help you find the U-Bolt Kit you need. We have some like the 1-1/2" Square # CE23102 or 1-3/4" Round # CE23000 depending on the size of your axle.

  • Replacement U-Bolts Compatible with CE Smith U-Bolt Kit for 1-1/2 Inch Square Axle
    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. 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.

  • Availability Of a Galvanized Trailer Axle For Building a Boat Trailer To Carry a Jon Boat

This is an 1,800lb axle with 57-1/2" from hub face to hub face and 46-1/2" from spring center to spring center. The CE Smith U-Bolt Kit # CE23102 is going to be what you need to attach the axle to the leaf springs. You will pair this with 2 of the Hub Assemblies # AKIHUB-440-2-G-2K.

  • Recommended 26 Inch Double Eye Springs for 1-1/2 Inch Square Axle Compatibility
    The 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # e94SR 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...

  • Replacement U-Bolt Kit, Leaf Springs, Bolts and Shackles for 68 Aristocrat Lo Liner Trailer
    Installing the U-bolts and plate like that would be fine, but I would recommend putting the plate on the leaf springs and running the U-bolts around the axle instead. The good news is you're replacing them so you can make that change when you install them. Once you have your axle measurements we do have some kits you could use. If it is a 2" square axle the # CE23103 or for a 1-1/2" square axle the # CE23102. If it is 1-3/4" you will need the # 175130 along with the # 116308. Since you...
