Video Transcript for CE Smith U-Bolt Kit for Round Trailer Axles Review

Speaker 1: Today, we'll be having a look at the CE Smith line of U-bolt mounting kits for mounting round trailer axles. Here's what our kit comes with. It's everything you need for replacing the U-bolts on a single axle on your trailer. We have 4 new U-bolts, you'll have 2 per side; 2 new plates, 1 per side; 8 new lock washers, you'll be using 4 for each side of the trailer; and 8 new nuts, again 4 for each side of the trailer.You can see how well our U-bolts grip around the contours of our axle. This'll keep the axle firmly attached to our leaf springs, so we don't have to worry about it slipping and sliding.Now because we have the zinc and the galvanized finish on our plate and our hardware, this will better protect them from corrosion from the elements, especially salt spray. It's not an issue if you decide to use them on a boat trailer such as this one.Now many of our customers have had to make a second phone call or send an email to us after they bought a new axle for their trailer because they found, once they tried to remove the old one or put the new one on, that they couldn't get their factory U-bolts off.

They had to cut them off, and now they're searching for a replacement. This kit will be a perfect solution for this problem here.Now many of our customers compared these to the Redline line of U-bolt kits. Now the main difference you're going to see between this one and those is that those do not have the galvanized or the zinc finish on the plates or the hardware, which will cause them to rust out faster.As you can see, we already have our new axle sitting on top of our leaf springs. Now this kit could work for an axle that sits on top or below your leaf springs. It works for both applications.

You don't need to worry if yours resides below, you can still use this kit for that.We'll start by taking our new U-bolts and dropping them over our axle on either side of our leaf spring. Now we'll take our new plate. We want to make sure that this flange right here faces down, this hole here in the center lines up with the alignment pin on our leaf spring, and we'll insert our U-bolts through the holes. Place on our lock washers, and we'll put that on our nuts.Now we can start to tighten our hardware, making sure we tighten them evenly as possible. Now we'll torque our hardware again, making sure we alternate to ensure that we're doing it as evenly as possible.And that completes our look at the CE Smith line of U-bolt kits for mounting round trailer axles..

Have not installed it yet so I can't review the product. I can tell you that etrailer's customer service is top notch. I called about a shipping delay after I placed my order. They assured me it would only be a day and not a week like my order confirmation said. Called back the next day and my order was already shipped. Good people to do business with. 666616

by:

The quality seemed good but causing doubt was that the holes in the plates were not totally cleaned out and had to be reamed out in order for the U bolts to go through. Not sure if it was the galvanizing that might have caused this. Either way, it seems like poor quality control. 662269

Ask the Experts about this CE Smith Trailer Leaf Spring Suspension

Do you have a question about this Trailer Leaf Spring Suspension?


  • Replacement 26 Inch Leaf Springs, Shackle Straps, And U-Bolts
  • To give you the correct leaf springs, I would need to know the capacity of your axle or what your Gross Vehicle Weight Rating (GVWR) is not just the weight of the trailer itself. This is the loaded capacity of the trailer. We have a few options for 26 inch leaf springs: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # SP-051275 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long...

  • Suspension and Trailer Tire/Wheel Combo Recommendation for Boat Trailer with 3.5K Axle
  • I do have just about everything you are needing. The only thing that we don't currently carry is a galvanized axle rated for 3,500 lbs. If you check with a local trailer garage/store they should be able to help you order one that has a galvanized finish that also have the correct hub-face and spring-center measurements for your application. A 3,500 lb axle should use inner bearing L68149, outer bearing L44649, and a grease seal that has an inner diameter of 1.719" and an outer diameter...

  • Replacement Axle for 1990's Karavan Trailer
  • The best option we can offer you is the Dexter Trailer Axle Beam part # 8327812 which has a 3,500 lb capacity and E-Z Lube feature. This axle has the same hub face length of 89" and drop of 4" that you were looking for. The spring center is set at 74" yes but you can move these inward to match your 70" spring center no problem. In regards to shape, square vs round this will also not be an issue. The u-bolts would be different yes but you would need to replace these when removed from the...

  • Trailer Suspension U-Bolt Kits for Round and Square Axles
  • We do offer u-bolt kits for trailer suspensions for both square and round axles. All of these are shown on the linked page. The nearest round axle u-bolt kits we have to your 2-1/2-inch dimension are kits # CE23002 and # APUBR-1 which are for axles with a diameter of 2-3/8-inches. But we do offer a single 2-1/2-inch u-bolt with nuts as part # 175668, the item you referenced.

  • Can 7/16" U-Bolts be Used for 3,500 lb Axle Suspension
  • As long as the 7/16" U-Bolts that you are using fit your 3,500 lb axle diameter correctly and they are rated for a 3,500 lb axle then you are good to go. We only carry 1/2" U-Bolts, parts # CE23002 and # APUBR-1, but when I reached out to my contact at Dexter Axle, who is one of the leading axle manufacturers, they said that 7/16" U-Bolts are fairly common for 3,500 lb axles.

  • Axle U-Bolt Kit for Single 2-3/8-Inch Diameter Trailer Axle
  • We have many sizes of round and square axle u-bolt kits that appear on the linked page. These are not rated by weight so you simply want to choose the one to match your axle diameter, which should be 2-3/8-inches. U-bolt kits # APUBR-1 or # CE23002 will do the trick.

  • Torque Spec for Tightening Nuts of 1/2 inch Diameter Trailer Suspension U-Bolts
  • For 1/2 inch trailer u-bolts that attach to axle the recommended torque value is between 45 and 70 ft lbs of torque.

  • Replacement Leaf Springs, U-Bolts, & Shackle Straps for 3,500 Pound 1981 Bass Boat Trailer
  • The leaf spring I recommend to replace your trailer's existing leaf springs is the 4-Leaf Double-Eye Spring for 3,500 Pound Trailer Axles # SP-212275. This spring measures 25-1/8 inches from eye-to-eye and will work well to replace the existing spring length. Based on your trailer axle's diameter, the capacity of the axle is 3,500, which is the axle capacity for which these springs are designed. The number of springs to not determine the axle capacity, so it will not affect your trailer...

  • Is the CE Smith U-Bolt Kit 23002 2-3/8 Inches Wide or 2-7/16 Inches Wide
  • The 2-3/8" measurement you are referring to on the CE Smith U-Bolt Kit part # CE23002 is in regards to the diameter of trailer axle that the kit is designed to be used with. The actual width of the u-bolt from the inside edge of each bolt is 2-7/16" and the diameter is 1/2". We do not have a u-bolt with a 2-3/8" width and a 3/8" diameter. However, as mentioned above if this is for a 2-3/8" (3,500 lb) trailer axle then you will want to use one that is slightly larger than the width of the...

  • How to Choose the Best Tires, Wheels and Axle for a Homemade Jet Ski Trailer
  • Finding the ideal tires, wheels and axles for your trailer will depend heavily on the overall weight of the trailer. For example, a jet-ski can weigh as little as 400-500 lbs on the light end and around 1,000 lbs on the heavy end. You must also consider the weight of the trailer itself sitting on the axles. Also, keep in mind that if the axle is positioned properly, the tongue of the trailer should hold about 10 percent of the total weight. For example, let's assume that your jet-skis...

  • Replacement Suspension Components for a 1987 Corey Dual Axle Trailer
  • It is always best to replace your suspension components on your trailer with products that are the exact same size as what you currently have. We do have the U-Bolt Kit # CE23002 which is for 3,500 lb axles that have a 2-3/8" diameter and these are 5-1/2" long. I would double check your 5,500 lb axle as that is not a capacity that I am familiar with. It may be a 3,500 lb that could have been misread as 5,500. You can also measure the diameter to verify that it has a larger capacity....

  • Recommended Replacement Tires for Lowered Trailer Currently Using LT235/75R15 Off-Road Tires
  • If your springs are already on top of your axles as it sounds, then you will lose the diameter or your axle plus the spring stack height when you flip the springs to the traditional location under the axle. This will most likely lower your trailer by a little over 3 inches. You need a new u-bolt kit for your axle, so I recommend the CE Smith U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts - Zinc # CE23002 if your axle is 2-3/8 inch diameter or # CE23003 if...

  • Should I Paint U-Bolts to Protect Finish
  • If you are concerned about rust and corrosion, an excellent option for you is the CE Smith U-Bolt Kit for Mounting # CE23002 which comes with galvanized plates and zinc-plated hardware. The u-bolts included are also 5-1/2 inches long and 1/2 in diameter just like in the APUBR-1 kit. You can apply a coat of rust-resistant paint to the U-Bolt Kit # APUBR-1 if you want to but it's not required. In fact, most people don't because these components, while susceptible to rust, are not directly...
