Video Transcript for Let’s Check Out the CE Smith U-Bolt Kit for Mounting Round Trailer Axles

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..

  • Replacement Axle for 2018 Grand Design Imagine 2150RB
    Grand Design lists an 86-1/2" 3,500 lb axle for your Imagine 2150RB. The next size up would be a 5,200 lb axle like the # e45GR. This has the same 86-1/2" hub face measurement but the spring seat is different. You will need to cut off the spring seats and weld on # TRSS300 to match your current 68-1/2" measurement. The CE Smith U-Bolt Kit for Mounting 5.2K to 7K, Round Trailer Axles # CE23003 will be required as well. For a hub and drum assembly you can use the # AKHD-655-6-EZ-K. These...

  • What Leaf Spring and U-Bolt Kit do I Need for My 2019 Keystone Cougar 26RBS?
    Hello Sean, I do not have a database that shows exactly what components are installed on each individual trailer, but based on my research, you should have a tandem axle setup with each axle rated at 4,400 pounds. You can check the axle tag to confirm the weight. If yours are rated for something other than 4,400 pounds, just let me know. You will want to go with the 4-Leaf Double-Eye Spring for 4,400 lb Trailer Axles Long # DX95CR. These measure 25 1/4", which lines up with your 25 1/2"...

  • Option For Replacing 3,500 lb Axle Part Number AADULE359582
    Thanks for getting in touch, Stanley. The part number AADULE359582 you provided indicates a 3,500 lb axle with a 95" hub face and 82" spring center. We offer a 5,200 lb replacement for this, the Trailer Axle Beam with Easy Grease Spindles - 95" Long - 5,200 lbs # e63GR. This axle has spring seats pre-welded at 80", so they will need to be removed and have new spring seats # TRSS300 welded on at 82". This axle tube is 3" in diameter so you will need new U-bolts such as part # CE23003....

  • Looking For Dexter Axle, Brakes, Hubs And Leaf Springs For RV
    Hello Brent, thanks for reaching out. We do have the hubs and brakes for Dexter 7K axles, but I am sorry to say we do not offer an axle that matches your specifications. We currently offer only two sizes of 7K axle, a 94" or 95" hub face. We can provide brakes, hubs and a suitable replacement for the leaf spring. Take a look at the following: - Dexter Nev-R-Adjust Electric Trailer Brakes - 12" - Left/Right Hand Assemblies - 7K # 23-464-465 - Dexter Trailer Hub and Drum Assembly - 7K...

  • What Parts Do I Need To Upgrade From 3,500 lb Axle To 5,000 lb Axle?
    Hello Jbryan, thanks for reaching out. I can certainly point you in the right direction. There are a few things we will want to look at here in order to be sure you get the right parts. Mainly I will need to know the hub face length and spring center length of the current axle. It is possible to upgrade the capacity, but the new axle will need to be identical in length to the current axle. For example, the Trailer Axle Beam # e55GR is 89" long overall and has a 74" spring center as you...

  • What Leaf Spring do I Need for My Dexter Axle with Weight Rating 4,400 Pounds?
    Hello Doug, Great question, and I am happy to make sure we get you into the right leaf spring. Since there is not a real standard for putting trailers together I am going to need a measurement from you. I need you to measure the Leaf Spring as unloaded as possible from eye to eye (please see attached image). Once I get that measurement from you I can recommend the right spring. For example, if your measurement is close to 25 1/4" then you will need the 4-Leaf Double-Eye Spring for 4,400-lb...

  • Is There a 6 Leaf Leaf Spring that Will Work as a Replacement for My Dexter Part Number 072-097-02?
    Hello Chris, We have exactly what you are looking for and it looks like you already found it, our etrailer 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # e94SR will work as a great replacement to Dexter's part number 072-097-02. Whenever you change out your leaf spring it is recommended to change out the u-bolts as well anyway because they do stretch over time, for the U-bolt kit you will want # CE23003. Getting things all geared up for nice weather? Any big trips planned...

  • What Suspension Upgrade Parts do I Need for My 2005 Challenger 5th wheel 29rpk?
    Hello Paul, Happy to get the right parts to upgrade your suspension on your 2005 Challenger 5th wheel 29rpk. I do not have a database that supplies me with what is put on what 5th wheel, so you are going to need to double check a couple of measurements. In my research I see that you most likely have (2) 5,200 pound axles (you can confirm this on the axle tag). - Shackle Strap Kit: MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR *you will...

  • Replacement Slipper Springs For The 7k Roadmaster Comfort Ride System
    Hey Jacob, To replace the 7k slipper springs from your Roadmaster Comfort Ride system you'll need part # RM75EQ. As with any leaf spring suspension if you replace one you'll need to replace the others as well so you'll need four of these. If you remove the two lower bolts from the slipper spring box that should be enough to get the springs out and then you can remove the eyelet bolts on the other side. Since you'll be removing the U-bolts to swap out the springs you'll want to also...

  • Recommended Roadmaster Comfort Ride System For A 2024 Forest River Riverstone Legacy 421FK
    Hey Jeff, To find the correct Roadmaster Comfort Ride kit for your 2024 Riverstone Legacy 421FK you'll need to check the axles for their weight capacity. Once we know the axle capacity we can pick the corresponding kit: 5k # RM-2460-2560-3 7k # RM-2460-2570-3 8k # RM-2470-2580-3 The slipper spring box would need to be aligned to the spring centers on the axle and center of the trailer frame when being installed so there isn't a separate alignment job that you'll need to complete afterwards....

  • Recommended U-Bolt Kit For 7k Round Trailer Axles
    Hey Rob, A 7k axle would have a 3" diameter tube so the CE Smith U-Bolt Kit for Mounting 5.2K to 7K, Round Trailer Axles # CE23003 would be the correct fit. These kits are for one axle each so you'll need to purchase one for each axle on your trailer.

  • Leaf Springs Equilizers, Shackle Straps, Wet Bolts, U-Bolts for 6K Axle on 2012 Prime Time 5th Wheel
    Hello Steve. Thank you for emailing me the picture of your suspension, as they are always most helpful. Leaf springs have the tendency to stretch out over time which does not give us an accurate measurement, so with your leaf springs measuring at 26" eye to eye I suggest you go with our 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # e34SR. After taking a close look at the picture you were able to email me it looks like you are referring to the equalizer, looks like...

  • Looking For 5,200 lb Axle With 86.5" Hub Face And 69.5" Spring Center
    Hello Travis, thanks for reaching out. We do have a 5,200 lb axle that measures 86.5" hub to hub. Take a look at the Dexter Trailer Axle # 8327816-EB. This comes completely loaded with electric brake assemblies and 6 on 5-1/5" hub/drum assemblies. The only drawback of this axle is the spring seats come pre-welded at 71-1/2". You will have to cut those off and have new spring seats, part # TRSS300 attached at 69.5". Aside from that, this axle matches all of your specs and comes with everything...

  • Recommended Replacement Axle and U-bolt Kit for a 2015 Keystone Montana High Country
    Hey Gerald, you could use the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # e94SR to replace your current springs but since you mention they are flat I'd recommend remeasuring the springs when they are unloaded. Whenever you go to replace your leaf springs in the future, you're going to want to make sure you measure them unloaded - that way you can be sure they'll fit. If that measurement is correct, then you'll just want the CE Smith U-Bolt Kit for Mounting 5.2K to 7K, Round...

  • Looking For Dexter U-Bolt Kit For 3" Round Axle
    Hello thanks for reaching out. We do offer U-bolt kits for 3" round axles, although we do not have a Dexter brand kit in this size. What we have is the CE Smith U-Bolt Kit # CE23003 which is designed for 3" round axles between 5,200 and 7,000 lb capacities. This is a full kit so you get U-bolts, nuts and plates; enough for one axle.

  • Looking For Leaf Springs For 2021 Grand Design Momentum 397Th With 7,000 lb Axles
    Hello Michael, thanks for reaching out. We do carry leaf springs for 7,000 lb axles, but there is no way to look up your camper to know exactly what spring you will need. RV manufacturers just are not that specific with their online literature. The main thing I will need to know is the length of the current leaf springs. It is best to jack up one side of the trailer so you can measure the spring without a load. Leaf springs are measured across from center eye to center eye. Also note...

  • Replacement Hangers, Equalizer, U-Bolts, Springs For a 2015 Keystone Carbon 327 5TH Wheel Toy Hauler
    Thank you the pictures are a great help.

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. We have the 3-1/4" Hanger # 28-5 which will work as a replacement for your front, center or rear...

    It sounds like you are definitely on the right track here. The # MR79ZR is indeed the correct suspension upgrade kit for your 2007 Colorado 5th wheel with LRE suspension. Moryde makes a fantastic suspension upgrade kit. The heavy duty shackles and wet bolts are highly durable and will last a very long time as long as you keep them properly greased. The shear spring # MR79UR is also correct for this setup. The leaf springs might be a bit more tricky, since you are measuring them under a...

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.

  • 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...

We don't currently offer a four leaf trailer leaf spring with a 6K capacity and 26" eye-to-eye measurement, but we do offer the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # e94SR. The amount of leaves in the stack doesn't really matter as long as your capacity and and eye-to-eye measurement is the same. Each leaf on your current leaf springs is just stiffer so...

  • Can New Spring Seats Be Welded Onto The Top Of An Trailer Axle Beam
    Yes, you'd just need to reach out to a qualified welder and have them weld on spring seats like part # TRSS300 to the top side of the Trailer Axle Beam with Easy Grease Spindles # e45GR. It's super common to do for people who have an underslung setup and want to raise the height of the trailer. When you remove the old axle you'll also want to replace the u-bolts with ones like part # CE23003 since they get stretched when torqued down and shouldn't be reused.

  • 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...
