Video Transcript for CE Smith Trailer Suspension - Leaf Spring Suspension - CE23103 Review

Today we're going to be taking a look at the CE Smith u-bolt kit for mounting 2" square trailer axles. The mounting kit is going to attach a trailer axle to the leaf spring. The plates are going to be galvanized steel, then the hardware is going to be steel construction but that's going to have a zinc plated finish on it, so overall the unit is going to do a great job at resisting rust and corrosion. This kit is going to include 4 u-bolts, 2 u-bolt plates, and then it's going to come with the appropriate hardware, so you're going to get 8 hex nuts and 8 washers, and those are going to be lock washers. We can tell that this is designed for 1 3/4" springs simply by taking a measurement between this hole and this hole, and we can see that- that measurement is right at 1 3/4". Now the plates themselves going this direction we're looking at 3 3/4", and then going this direction it's going to have a measurement of 4". It does have the center hole for punch out on the spring.

Then right here for the u-bolts, a couple measurements I want to go over with these, these are going to give us an inner width, measuring inside edge to inside edge, of just over 2" so that's how we know that there are designed for a 2" wide square axle. Center on center those posts are going to be separated by 2 5/8". The length, measuring from the bottom of this area here to the end of the stud, that's going to give a measurement of right at 4 1/2". Then the diameter of the u-bolts, so the thickness right here outside edge to outside edge, there are going to be a 1/2" diameter. That's going to do it for today's look at the CE Smith u-bolt kit for mounting 2" square trailer axles.

Arrived well packed and as advertised.
I'm
going to pull the azle out of the boat trailer
and wanted to have this 'on hand' should I break
some of my U bolts. I've bought from you before -
always been happy, thanks

Worked perfect for mounting a storage box to my boat trailer.

Service is outstanding

Sold trailer



by:

Everything fit perfect. I had to replace the leaf springs on my boat trailer. I have a 24' fiberglass boat that is launched and retrieved in the salt water the original springs only lasted 7 years. The new springs are heavier duty and painted or coated with a better material. Over al very very pleased.

After 1 year everything is still workong great.



by:

The 26” on center leaf springs that I just purchased were delivered quickly and worked perfectly on my trailer. The only issue was that I ordered 3” shackle bolts (my fault) but really needed 3 1/2” so I returned them to etrailer. The return process was very easy, they sent me a RMA # and the shipping label my email, and I just dropped it off at the UPS store. Great doing business with etrailer!!!!!



by:

Good product, fit as expected. One year in and ubolts are holding up great.



by:

Complete waste of time and money. I bought both springs, and this set of u-bolts plates from etrailer for a new 2" square axle. The u-bolts are too short. I'd suggest someone buy a new tape measure.
I also had to grind down the spring center bolt as it stuck out of the small adapter plate and kept the spring from seating correctly (used the adapter palte which came with the springs instead of drilling a big hole in my brand new axle.)

It is getting harder and harder to get the parts I need from these folks.

Now waiting for parts to come from another vendor.



by:

I used this kit to replace the rusted ones on my flatbed trailer. I also flipped it so the axle is on top of the springs to lower it for loading my lawn tractor. See before and after pics.



by:

Exactly what I needed



by:

Exactly as described. Made replacing my axle a piece of cake!



by:

Good parts but they will not fit on springs with 6 leafs. The ubolts are too short. You need 5” bolts or longer.



by:

WOW sums up my recent trailer part purchases. The u-bolts fit perfectly and are well made...see attached photo and of my trailer with new parts installed. Outstanding quality, price, lightning fast delivery, and exceptional customer service from order to drop off at my doorstep. Will recommend and order again. Well done, e-trailer, and Thanks.



by:

Fit my load rite boat trailer, bought with springs. Good quality!



by:

Will work with the springs I purchased, but beware if your spring pack is over an inch thick on a 2x3 axle, you will need longer u bolts. And I didn’t see longer than 4.5” offered at etrailer



by:

Good Stuff



by:

Excellent product, perfect fit for my older trailer. Great customer support via phone to confirm all measurements before buying. Very happy customer!



by:

Easy transaction. Quick delivery. Parts in good condition and fit/work well. Installed in less than 1 hour.



by:

Good stuff and a day early!



by:

Out standing as all was. shipping is out standing order them on Friday after hours they where at my door Tuesday the next week out standing shipping. I did the same thing with brake plates all ready to put in ordered Friday I was in Oregon at the time they was at my house the next Tuesday or Wednesday standard shipping is out standing a long with everything I got here.



by:

Very helpful great customer service



by:

Perfect replacement for my 1971 Streamline Duchess spring over axle conversion



by:

Perfect timing,and they have everything you need!



by:

Good setvice. Just what I ordered.



by:

Wth rusted out leaf springs on my trailer but with zero experience replacing them, I contacted etrailer and Shawn was very helpful in selecting the right parts and taking me through the process. She was patient in terms of helping me take the right measurements and suggesting the bolts and pieces I needed to do the job right.

Everything came well packaged and complete two days later. An hour after that the springs were in my trailer and now has a boat sitting on it.

Thanks!



by:

Good shipping time and well packaged. All items arrived intact. All parts are in great condition and fit perfectly.

  • Replacement Suspension for Tandem Square Axle Venture Boat Trailer
    I reached out to the manufacturer but they are not currently able to look up VIN numbers for part assistance. I was able to find on their website that the square tube axles are either 2000 lbs capacity each or the more common 3,500 lbs capacity each. Most of their trailers utilize the 3,500 lb axles and I believe that is the case for all their tandem axle trailers. For your trailer you can use the following: -Tandem-Axle Trailer Hanger Kit for Double Eye Springs - 3-3/4" Tall Front/Center/Rear...

  • Can 2" Square Axle on Cattle Trailer Be Flipped
    We don't have a full kit, but you can use the CE Smith U-Bolt Kit # CE23103. You will also need to cut off your spring seats and weld on the old ones or new ones to the top assuming your axle uses them. Spring seats for a 2" square axle are not something that we carry. Alternatively, you may need to drill a hole if that is what you have now instead of spring seats. It all depends on your current setup since it varies on square axles. Adding taller hangers like the # E4139 you looked at...

  • Need for Additional U-Bolts to Install CE Smith Roller-Style Guide-Ons CE27610
    The CE Smith Roller-Style Guide-Ons # CE27610 will fit your 2 x 2-inch trailer frame. The standard included brackets work with frame members up to 3-inches wide and 4-1/4-inches tall. It is a good idea to add another u-bolt to each guide-on in your application. I linked our main page for trailer u-bolts where you can see items like CE Smith U-Bolt Kit # CE23103 and # UBZC12X212X525.

  • Replacement Springs for Fulton Boat Trailer
    Your 32 inch springs were likely a little shorter than that originally and have flattened over time. It sounds like what you are looking at, the 4-Leaf Slipper Spring w/ Flat End part # SP-040275, a 30" long x 1-3/4" wide will work. If you need it, there's a U-Bolt Kit # CE23103 and for suspension bolts, the Spring-Eye Bolt with Locknut for Slipper Springs, # 166079.

  • Availability of 3 x 4 Inch Axle U-bolts
    Are 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...

  • 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.

  • 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

  • Recommended Trailer Components Between Frame And 2 Inch Square Axle Of Small Trailer
    For your trailer with GVWR of 780 lbs, the best option we have for your leaf springs is the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 20-3/8" Long # e84SR you mentioned but they are definitely overkill. To mount your springs to your frame, I recommend the Single-Axle Trailer Hanger Kit for Double-Eye Springs - 1-1/2" Front, 7/8" Rear # APS1 which will need to be welded in place.

  • Can Nylon Lock Nuts Be Used On CE Smith U-Bolt Kit CE23103?
    While you could physically replace the lock washer and nut included with the CE Smith U-Bolt Kit # CE23103 with nylon lock nuts, I do not recommend doing so. Nylon nuts deteriorate overtime and can back off where the lock washer and nut included will stay tight, and are also what these U-bolts were tested and designed for. I included a video of the # CE23103 for you to take a look at.

  • Needing U-Bolts to Fit Around 2x3 Trailer Frame Member
    Given the dimensions you provided, I believe that a u-bolt kit such as # CE23103 that's typically used to mount a 2 inch square trailer axle to the leaf spring pack would be your best bet. The kit includes two assemblies, each of which includes two 4-1/2 inch long 1/2 inch U-bolts with a 2-1/8 inch inside span, two bolt plates and the necessary nuts and lock washers. I've linked to a product description video for the U-bolt kit I recommended.

  • My 1971 Ideal Camper Has a Different Leaf Spring On One Wheel and Random Hardware In Suspension
    With the age of your 1971 Ideal 22' Camper I am going to recommend changing out all the suspension components. I happened to notice some of the hardware was also replaced at some time as well and it does not look like they used the correct parts either. For the Leaf Springs you will need to jack up the camper to remove as much weight from the suspension as possible. You will need to measure the spring in a few places to be able to ensure that you find the correct replacements. I have...

  • Is There Way to Do Over Under Kit with 2 inch Square Axle on Trailer
    We have 2 inch square U-bolt kits like part # CE23103 which you could use, but we don't have spring seats for this axle size. So you would have to remove the spring seats on your axle and weld them on the other side and you'd be have an over-under kit that fits your axle. You might have to drill spring seats in the axle.

  • Can Axle Over Under Kit be Installed on Trailer with 2 inch Square Axles
    Axle flip kits are great options for raising the suspension of a trailer. Trucks weren't as tall back then as they are now so I'm not totally surprised your trailer is sitting so nose high. We have 2 inch square U-bolt kits like part # CE23103 which you could use, but we don't have spring seats for this axle size. So you would have to remove the spring seats on your axle and weld them on the other side.

  • Replacement Leaf Springs for Wesco Boat Trailer
    For a 3,500 lb trailer axle leaf spring I would recommend the galvanized part # e68SR which is 25-1/8 inches long. Galvanized steel holds up a lot better to rust than standard steel and while this is a little shorter than what you have now worn out springs tend to flatten out and get longer over time. For a 2 inch square u-bolt kit then you'd want the part # CE23103 and you'd be set. To pick out an axle you would need to know the hub face to hub face dimension as well as the spring seat...

  • Does 3,500 lb Leaf Spring Need to Have Same Number of Leaves as Original
    Yes, you can replace your 3,500 lb 7-leaf springs with leaf springs that have 3 or 4 leaves because the weight rating is the same. The number of leaves isn't a determining factor; for example, there are 4-leaf springs for both 2k and 6k axles. So you simply need springs with the correct rating for your axle, as well as the right length. For that, you'll want to measure the length from center-to-center of the spring eyes, taking into account you current leaf springs will have elongated...

  • How To Flip Square Trailer Axle For Ground Clearance
    It is possible to mount the springs on top of the axle which is called "flipping the axle". To accomplish this we normally recommend an over-under conversion however there is not one with square u-bolts available for your square axle. Instead I recommend to use CE Smith U-Bolt Kit for Mounting 2" Square Trailer Axles - 4-1/2" Long U-Bolts - Zinc part # CE23103 which is galvanized for boat trailers. The U-bolts measure Inner width of 2-1/8" with a length of 4-1/2" and diameter of 1/2"....

    The CE Smith U-Bolt Kit for Mounting 2" Square Trailer Axles # CE23103 that you referenced would work well for you as they are designed specifically for 2 inch square trailer axles like what you have. The weight of your trailer and boat would not be an issue at all.

  • Replacement Leaf Spring and Hanger Kit for Boat Trailer that Weighs 3,995 lbs
    The best option is going to be a 4,500 lb leaf spring part # e27SR which is a double eye spring that is 26 inches long. For a single axle hanger kit to use with this since you'll need new hangers you'll want the part # APS4. You might be able to use your current u-bolt kit but if you need a u-bolt kit and you have 2 inch square axles you can then also use the part # CE23103. If you have a different size axle let me know.

  • Can Round Trailer Axle be Replaced with Square Trailer Axle
    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

    For your 2,000 lb square axle, I recommend the 3-Leaf Slipper Spring w/ Flat End for 2,900-lb Trailer Axles - 30" Long # SP-039275 which is a little stronger than your axle but won't increase your capacity of 2,000 lbs. This is a 30 inch long slipper spring with a 1.75 inch width as you stated. I recommend using the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079 with each spring.

    Thank you for the photos! They really helped. For your double eye leaf springs, the 4-leaf 25-1/8" Long, part # e54SR, that you referenced are in fact the right ones for you. The reason they are slightly shorter than your current ones is because they tend to stretch a little over time. Also, remember that you will need two.

    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...
