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..

The u-bolts and plates are of excellent quality. Bolts are yellow cadmium plated and the plates are hot dip galvanized. The fit was perfect, no issues at all during assembly.

Great customer service...received product as promised. I have outfitted my trailer to organize and carry all my construction tools for building and remodeling. The springs are a noticeably stiffer than the smaller factory springs I had on trailer; however , that’s what I intended to get by upgrading. I have every confidence that these won’t break like the cheapass factory springs Stealth put on their 14’ enclosed trailer. (No, I didn’t overload the trailer—the original springs failed due to the very thin metal and fatigue.)

The materials and finishes look to be good quality, but the threads on the U-bolts were dinged in several places. The damaged threads made it difficult to assemble the nuts and one nearly galled stuck before it could be tightened all the way. It looks like the damage happened during manufacturing since the packaging was very protective. I'd buy these again if not for all the dinged up threads.

Ask the Experts about this CE Smith Trailer Leaf Spring Suspension

  • Recommend U-Bolt Kit for a 3 Inch Diameter Trailer Axle
    If you have a round 3" diameter axle on your Spartan boat trailer then you are going to want to use the CE Smith U-Bolt Kit part # CE23003 which contains u-bolts that are 7" long x 3-1/8" wide x 3/8" diameter. The reason you need this size u-bolt for a 3" diameter axle is because the u-bolt will need to be wider than 3" in order to fit a 3" diameter axle and significantly longer than 3" in order to attach the plate over the leaf spring stack. Unfortunately, we do not have a u-bolt in...

  • Distance From Inside Arc Area Of U-Bolt To Threads For U-Bolt Kit Mounting Kit
    I pulled one of the U-bolts we offer from our warehouse and took a quick measurement for you. The distance from the inside of the inside arced area of the U-bolt, part # CE23003 to the threads on the leg is 4-3/4 inches. The threaded portion is 2 inches. I also pulled another set of U-bolts, part # APUBR-8 and the measurement from the inside of the arc to the threads is the same 4-3/4 inches as well as the threaded portion being 2 inches. This is a 1/2-20 fine thread U-bolt.

  • Parts Needed to Make Over Under Axle Kit for Trailer with 7k Axles
    You'd need new u-bolts like the part # CE23003 and then spring seats like part # TRSS300 and you'd be able to make an over under axle kit for your trailer with 7k axles. Basically you install the new spring seats on the opposite side of the axle and then move the axles to the other side and secure them with new u-bolts.

  • Replacement Leaf Springs for a 4400-LB Axle on a 2016 Grand Design Refrlection
    For your 2016 Grand Design Reflection 29RS, we have two possibilities for replacement springs that work for 4400-lb axles. You need to measure from the center of one eye of the leaf spring to the center of the other to get the proper length. However, since yours are flat, they have stretched quite a bit. So, an accurate measurement will be difficult. More than likely, you will need the 26"-long 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles, part # SP-256275. I've linked to a video...

  • Recommendation to Replace Double Eye Leaf Springs on Montana 5th Wheel Trailer
    I am happy to get your Montana 5th Wheel Trailer all set up with new suspension components. When picking out replacement leaf springs, it is important to keep in mind that older springs will have stretched out a bit from their original length. This difference likely won't quite be the 1-1/8 inch difference between the 26 inch measurement you took on your springs and the 24-7/8 inch Double-Eye Springs # SP-222275 you referenced, but it is still a good idea to select a leaf spring stack...

  • U-Bolt Kit Recommendation for a 3 inch Diameter Axle
    Sounds like you are looking for the CE Smith U-Bolt Kit part # CE23003 which is a kit for 3 inch axles, has u-bolt plates and matching nuts. The length of the bolts is 7 inches and the diameter of them are 1/2 inch.

  • 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...

  • Replacement Leaf Springs for 1998 Coachmen Catalina 364 TBS
    Based on the weight capacity you mentioned seeing on the spec sheet the best option for a leaf spring would be the part # SP-222275 which is for a 5,300 lb axle but is a bit shorter at 24-7/8 inches which is more common on the higher capacity axles. So then for a U-bolt kit you'd want the part # CE23003 which fits the 3 inch round axles which are the size of 5,200 lb axles. It will probably make the most sense to go with a new hanger kit too since the leaf springs are a shorter and...

  • Converting Triple Axle Trailer From Slipper Springs to Double Eye Springs
    You will need to weld on new spring hangers to convert your triple axle trailer from slipper springs to double-eye leaf springs. The linked page shows you all hangers. Select hangers of the same height as the current ones to keep the trailer's stance as it is now or taller ones if you want to raise its height. For selecting cushioned equalizers you will want to match the hole spacing dimensions to your current equalizers. Please refer to the linked page showing cushioned triple-axle...

  • Replacement U-Bolt Kit For Dexter 4400lb 3" Axle With 6-Leaf Springs
    The CE Smith U-Bolt Kit # CE23003 will fit your 3" round Dexter 4400lb axle. The U-bolts are 7" long. The 6-Leaf Double-Eye Spring # SP-256275 uses 6 leaves that are 3/8" thick which will make the spring pack 2-1/4" tall. When you add that to the 3" axle and 9/16" spring seat you have a total thickness of 5-13/16". That leaves you 1-3/16" for the spring plate and nuts.
