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.

I'm very happy with my purchase. I actually ordered a different set of u-bolts, which was apparently out of stock. I received a phone call from an associate who was very meticulous about making sure the replacement set would fit my project the way I needed it to. She had three possible alternatives and we figured out the correct one and it was shipped out the same day with my other purchases. These u-bolts fit perfectly and everything arrived in good condition. Etrailer was recommended by a buddy and I'm glad it was; great experience. 571306

The product is good quality but when you add the axle spring seat, which is necessary so you do not have to drill a hole in the axle, then the U bolts are not long enough and you have use a 5 1/4" U bolt not included. 311761

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! 418373

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. 482086

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. 405896

Ask the Experts about this CE Smith Trailer Leaf Spring Suspension
Do you have a question about this Trailer Leaf Spring Suspension?


  • Recommended Axle Mounting Hardware for Square Axle
  • It sounds like the axles were attached with 2 inch U-bolts that are 1/2 inch diameter which are a standard size so it sounds like the axles are compatible with a standard U-bolt kit like the CE Smith U-Bolt Kit for Mounting 2" Square Trailer Axles - 4-1/2" Long U-Bolts - Zinc # CE23103. If this is the case, that is my recommendation. This will work well with 1-3/4 inch wide leaf springs. If I misunderstood and the 2 inch U-bolts were bent out to fit a 2-1/2 inch wide square axle, then...

  • 2 inch Square Axle U-Bolt Kit Recommendation for a Boat Trailer
  • 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 Slipper Springs for a 2,100 lb Trailer
  • The most important factor in picking out a new leaf spring for a trailer is to match the capacity needed. Going with a 3,500 lb spring for a 2,100 lb trailer is going to give you a very harsh ride. For a spring similar to the # WIG4 that is better rated for your trailer we have the # SP-039275 which is for a 3,000 lb axle or part # SP-038275 for a 2,000 lb axle. If you need all 2,100 lbs of your trailer's capacity you would have to go with the # SP-039275. If you have a 2 inch square...

  • Switching From Slipper Springs to Double-Eye on a Single 2K Axle Trailer with Square Axle
  • To 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...

  • 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

  • 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.

  • Recommended 30 Inch Slipper Springs and 2 Inch Square Axle Mounting Kit
  • 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. For your square axle mounting, I recommend the CE Smith U-Bolt Kit for Mounting...

  • Available Trailer Suspension Square U-bolts Kits
  • We carry all sorts of parts for trailer suspensions, including U-bolts for both round and square axles of various dimensions. Our main pages for all trailer suspension parts and for U-bolt kits are linked. We have complete u-bolt/plate kits for 2-inch square axles, part # CE23103 which has an inside width of 2-1/8-inches. Depending on how you measured your u-bolt this may be the kit you need. We also sell u-bolts with hardware on their own, without plates, such as # CE15501A which...

  • 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.

  • Hanger Kit Recommendation for Slipper Leaf Spring # SP-264275
  • Sounds like what you are in need of is a single axle hanger kit for the leaf spring part # SP-264275 that you mentioned. For that you'd only need the # APS3SE and you'd be set. This gives you the hangers for the front and rear for the spring as well as the correct nut and bolt to hold it all. For a u-bolt kit you'd then want the part # CE23103 for the axles.

  • Determining Need to Replace Trailer Suspension Components
  • If your shackle links, shackle bolts and hangers are all in good condition - meaning no obvious deterioration, damage or evidence of holes having become egg-shaped from wear - you could re-use them. But in the scheme of things these parts' costs are fairly low so if you're going to the effort of upgrading your camper's suspension I suggest you eliminate any potential doubt/concern by replacing these items if you have any reason to think they're past their working lifespan. If you...

  • 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 # SP-169275 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. To mount your 2 inch square axle, I recommend the CE Smith U-Bolt Kit for Mounting 2" Square...
