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.

U are awesome .. luv ur customer facing systems . Luv ur work ethic …
You’ll always have me as a customer.
I’ve gotten u a customer that is a boat and trailer repair yard.. They are also impressed…
Whatever systems u integrated tell ur It guy he’s captured lightning in a bottle.



by:

Just mounted my 1.5 inch square axle today using this item. Worked great. I used a cradle to align my axle on the slipper springs (no holes needed i. axle) but the cradle added about 1/4 inch. This means there were no extra bolt threads extending beyond the nut. The lock washers were fully compressed, though. The red on the bolt threads in the pic is just grease.



by:

The product seems fine. I haven't installed it yet. That said the packaging was absolutely horrible. The springs had come out of the box while enroute. The UPS driver was nice enough to keep it all together and stayed with me so I could verify that everything was there. I was almost thinking of sending you a picture of the box as the flaps were secured properly but there was obviously not enough packing to keep the springs from moving around inside the box and they blew out the side of the box.

works good with leaf springs.

After a year the suspension is still as good as new.

I often purchase from each trailer and have always been very satisfied



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:

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:

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:

Paul helped me a lot. The axel fit just right.



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:

My order arrived as described and worked perfectly.



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:

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



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:

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.

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.

Since I was replacing all 4 leaf springs on our trailer ,it made sense to replace ubolts and plates. Was easy to find what i needed on website. Price was great. Made project simple.

4 new leaf springs and new mounting hardware, puts your mind at ease traveling. Very easy to find correct replacement parts .



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.

  • Recommended U-Bolts And Plate For A 1-1/2" Wide Square Axle
    Hey Roy, The only U-bolt kit we currently only offer for 1-1/2" square axles is part # CE23102, which only has a 3-3/8" length so it likely wouldn't be the best option for you. Instead you'll want to order the 1-1/2" Square Trailer U-Bolts # SP01-120 and two of the U-Bolt Plate # 115983 to mount your axle to the leaf springs # SP-210275.

  • U-Bolt Kits Available For Different Size Axles When Adding New Hangers
    Our U-Bolt kits are available separately due to axles having different sized and most hanger kits can be used with several different size axles. Here is a list of different size kits depending on your axle size. 1-3/4" Round Axle # CE23000 2-3/8" Round Axle # CE23002 3" Round Axle # CE23003 1-1/2" Square # CE23102 2" Square # CE23103

  • Replacement Leaf Springs and Hardware for 2008 Venture Boat Trailer
    To find replacement leaf springs you will need to know your axle capacity along with the length of your current leaf springs. If you don't already know the axle capacity I would try checking the axle tag to see if it is listed. If not, you can call Venture with the VIN and they should be able to tell you. Once you have the capacity go ahead and measure the length of your leaf springs. This is the spring eye to spring eye measurement. I have attached an article below which has a video...

  • 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.

  • What Does the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles # CE23102 Come With
    The CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles # CE23102 that you referenced includes two u-bolt plates, 8 nuts and washers, and 4 u-bolts. In other words it comes with two sets and not just one like you asked.

  • How to Determine Correct Slipper Spring Replacement for 1,500 lb Axle
    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. There are no slipper...

  • 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...

  • Square U-Bolt Kit for Mounting Leaf Springs SP-177275 to 1-1/2 Inch Square Axle
    You 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.

  • Replacement 1-1/2 Inch Square Axle for a Boat Trailer
    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.

  • 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.

  • Replacement 26 Inch Long Leaf Spring and U-Bolt Kit for Lightweight Square Axle Trailer
    We do have some parts that will work for your application! For leaf springs you'll want to choose one of the following based off of the weight capacity: 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - # e77SR 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - # e27SR Then for a U-Bolt kit we have the CE Smith # CE23102 designed for 1-1/2" square axles. Attached are some videos for you to check out.

  • Replacement Leaf Springs and U-Bolts For Karavan 1,000LB Single Square Axle Boat Trailer
    The 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.

  • 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.

  • 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.

  • 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...

    The best option we have for you is the 3-Leaf Double-Eye Spring part # e84SR 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.

    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.

    Yes, 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

    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.

    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....

  • Availability of Spring Seats and U-Bolt Kit for 1-1/2" Diameter Axle
    Hi Darren; unfortunately we don't have anything that will fit a 1-1/2" diameter round axle. I'm only seeing options for 1-1/2" square axles when I run an internet search like our # CE23102 but it doesn't mean they don't exist. If you can't find them anywhere else and you don't want to repair the weld I would say you need to reach out to a local fabricator. You can probably find the U-bolts at a local hardware store and have them fabricate spring seats and the U-bolt plates.
