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 product themselves are quality however, the customer service and shipping is what was dissapointing. I originally ordered 4 items. I was told only one item was on backorder. Not a big deal. I checked a week later on the backorder and was told that they did not know when an item would come from the namufactuere. However, it was a different item from the first. So two items were not available and turned out to not be available. It was a lack of communication and I had to figure this out by calling after waiting a week and several misguided emails. Next was the packaging. It was all broken up and taped when I got it. Whoever packaged these items threw 4 heavy leaf springs and 2 sets of U-bolts into a box without securing them. They arrived but the two U-bolt packedges were previouly opened and sealed with masking tape and i'm missing all the nuts and lock washers from one package. The box could have come open during shipment but they were not secured inside the box at all, which led to the catstrophy inside the box. Due to all this, I will probably not order again from this site.



by:

The bolts worked great but the base plate was not drilled out enough to be able to fit, I had to reuse the old plates which worked fine.



by:

Good packaging. Great replacement for the old U-bolts.



by:

These 2 new spring sets replaced OEM Dexter set used by Keystone. They worked fine but appear to be a bit thinner steel than the OEM unit that failed on one leaf. I asked the etrailer rep and was told they are rated for my RV so we will see.



by:

I did not receive the U Bolts, they were not in the box with the other parts.

by:

What excellent service I received. I received my shipment promptly and one of my items was ordered incorrectly. I wish I had known but was not too bummed. It was probably my mistake. When I called to re-order the rep recommended I go right to the manufacturer for the special part, and gave me the number. etrailer credited my credit card for the incorrect part and because it was not an expensive item did not require me to return it. Thank You!!!

High quality parts

The UBolts plates didn’t fit had to use my old ones. The span was not wide enough for the u bracket to sit start through.

  • 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 # e27SR I've linked to a video review...

  • 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 Spring For A 2014 Heartland RV Landmark Fifth Wheel
    The 6-Leaf Double-Eye Spring for 7,000 pound Trailer Axles # e64SR is 24-7/8 inches long and since your springs measure out to be 26 inches when fully loaded these springs will work on your 2014 Heartland RV Landmark Fifth Wheel. The springs have a sturdy steel construction and have the nylon bushings included. The spring capacity is 3,500 pounds which makes the axle axle capacity 7,000 pounds. If you need a new U-Bolt Kit # CE23003 is the kit you will need. I attached a review video...

  • Can A Roadmaster Comfort Ride Suspension Be Installed A Trailer That Rides Slightly Nose High
    Yes, you can still install the Roadmaster Comfort Ride Leaf Spring Suspension Kit even though the trailer rides slightly nose high when coupled to the tow vehicle. When installing one of these kits you'll most likely need to get longer U-bolts since there typically aren't enough threads to accommodate the additional mounting brackets. To determine the right kit and U-bolts you'll need to know the capacity and diameter of your axles and how many axles your trailer has. 3.5k 2-3/8" Tandem...

  • Replacement Hub/Drum For Lippert Hub Stamped 122093
    While we do not have the exact Lippert hub/drum we do have the Dexter # K08-201-98 equivalent. This hub has the same 6 on 5-1/2" bolt pattern and fits the same size spindle. The hub includes all new bearings, races, spindle nut, retainer, grease cap, plug and lug nuts to replace your Lippert. We also have the Bearing Kit # BK3-300 if you are only replacing the single hub. For the Bolts and plate we have a basic Set # APUBR-9 or you can get the Coated # CE23003 for superior corrosion protection...

  • Leaf Springs and U-Bolts for 2010 Keystone Cougar Travel Trailer
    The best leaf spring option we have is the part # e28SR which has a 5,000 lb axle capacity and is 25-1/4 inches in length. Old springs do tend to stretch a bit over time but in your case this capacity matches what you are in need of and is a close enough length that it would work well. Then for a u-bolt kit for a 3 inch diameter axle you'd need the part # CE23003 which comes with plates and nuts/washers.

  • Availability of a Trailer Axle With at Least 5,000LB Capacity and 86-1/2" Hub Face To Hub Face
    We do have the Dexter 5,200lb Trailer Axle w/ Electric Brakes # 8327816-EB which matches your current axle hub face to hub face of 86-1/2". This axle includes the 12" drum brake assemblies and it will increase you to the 6 on 5-1/2" bolt pattern. You will need to have 2 new Spring Seats # TRSS300 welded on at your 68.5" measurement on top of the axle as well since the spring seats on this axle are 71-1/2" on center and located on the bottom of the axle for an underslung design.

  • Upgrading The Suspension On A 2015 Dutchmen Aerolite Travel Trailer
    Awesome! It sounds like you are definitely on the right track here. The leaf springs # e22YR will work perfectly at 26" long and should be a bit of an upgrade from the current spring. The Moryde equalizers # MR27ZR are also a great choice. Now we cannot always go off of the wheelbase to determine fitment. We would want to compare the size of the current equalizer to the Moryde equalizer. Measured center hole to center hole, the Moryde is 8" long and 3-1/2" tall. I have attached a picture...

  • Recommended Suspension Upgrade Kit For A 2013 Keystone Energy 300FBS
    I can certainly point you in the right direction. The best suspension upgrade for your 2013 Keystone Energy 300FBS will be one of the MORryde Suspension Upgrade Kits. We have the # MR46ZR which comes with 2-1/4" long shackles, or the # MR76ZR which comes with 3-1/8" long shackles. The MORryde kits have heavy duty extra thick shackles, bronze bushings and wet bolts. With proper maintenence, these will last much, much longer than the stock suspension.

  • What Info is Needed to Pick Out Replacement Axle and Leaf Springs for Trailer
    When picking out an axle for a trailer you'll need to know the overall length of it from hub face to hub face as well as the distance between the spring seat centers to pick out correct size. I also attached a link to a page with all of the axles we carry. To pick out replacement leaf springs you would need to know the axle capacity and length of your current springs. I also attached a link to all of the 6k leaf springs we carry as well. Then for a U-bolt kit you would want the part #...

These straps are much thicker than the thin straps you got from the factory so they will not elongate like your current straps which now measure 1/8" longer.

You will need to source the angle iron locally to mount the Triple Axle Hanger Kit # APTT5. Once you have the hangers welded in place you will be able to have the assembly galvanized at a local shop.

    I reached out to my contact at Dexter and based on the part number you provided you have an older mobile home axle that has an 86-1/2" hub face to hub face measurement, and 75-1/2" spring center to spring center measurement. They were unable to find the exact weight rating of the axle. Based on the hub face length you need for a replacement we have the Trailer Axle Beam with Easy Grease Spindles - 86-1/2" Long # e45GR which has a 5200lb axle rating which would be a great choice.

  • 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.

  • 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...

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.

Since the height would be slightly different you would want to replace all of your springs on your trailer.
