Video Transcript for TruRyde Trailer Suspension TRSS175 Review

Today we're going to be taking a look at a spring seat for typical 2,000 pound, round trailer axles, with a 1-3/4 inch diameter. The spring seat is a necessary component of your trailer's suspension system. When mounted with a 1-3/4 inch wide leaf spring, it adds extra support and provides proper positioning for the axle. This unit's made from a durable steel construction. It welds on to a round 1-3/4 inch diameter axle, which is a typical 2,000 axle. It sits on top of a 1-3/4 inch wide spring. The cut out on the flat side of the seat surrounds the raised knob on the leaf spring to prevent turning or shifting.

It's going to provide extra support and secure positioning for the trailer axle. Please note that two spring seats are required for each axle. A few measurements to go over with you real quick. Start with the overall length, measuring edge to edge. It's going to measure about 2-1/4 of an inch long. Overall width, measures about 1-7/8 of an inch.

The height, is just shy of 1 inch, about 15/16 of an inch tall. Then this opening, right here, the rounded point, at the widest spot, that's going to give us an opening measurement of really close to an 1-1/2, maybe 1-7/16 of an inch, right in that area. That's going to do it for today's look at the spring seat for typical 2,000 pound, round trailer axles, with a 1-3/4 inch diameter.

Fit fine,just what I need for my 4x8 trailer repair.


Great fit spring seats worked perfectly


These brackets used in conjunction with the new u-bolt kit made switching my trailer axle from being above spring to under spring.
This has raised the trailer about 3 inches in height from stock. I have a new set of wheel and tires coming and this should take care of the slight slope as seen in the picture.
After installing everything, I took the trailer for a test drive and it tracked nicely and behaved very good on the road. No problems.


I havent really gotten a chance to use the trailer much since my purchase of the leaf springs. But they went on perfect and the stance is perfect. With a weight load , they should be just right.


I was adding some supports to a trailer deck for a friend and noticed the spring seats were rusted away, found the parts quickly on etrailer shipping was fast and the trailer is ready to get back on the road.

The spring seats and u bolts kit were very reasonably priced and do the job they are supposed to do.


First and foremost, working with etrailer was a pleasure. They were veery helpful in many ways. Secondly, Theproducts I purchased were exactly what I needed. I flipped the axle on my utility trailer in order to beef up the springs and use larger tires. The u-bolt kits were oerfect, and after having the spring seats welded onto the axle the rest of the job went smoothly. All in all 5 out of 5.


so far so good, just did a shake down test, all good. The trailer went straight and true. Now just waiting on my other order to come in so I can put some weight on the truck and trailer for the real test.


Perfect for an axle leaf over mod. Welded on easily and appear very sturdy. I need to rebuild the hubs and complete the frame modifications before reinstalling the axle.


Good products for a super low
price. Accomplished the goal of bringing life back to a dead trailer. The leaf springs ride much better than the stock rubber torsion axle. The new hubs and bearings roll much easier than the worn out ones they replaced.

A little disappointed in the spring bushing. It seemed like cheap plastic and was quite a bit larger than the bolt so it fit loosely. This was the only real negative I have about the purchased, and that's pretty minor.

Tips for etrailer:
Providing a height of the spring would make spring selection easier. In our case we were starting with scratch for mounting springs, no preexisting mounting hardware. Knowing the height of the spring from mount to axle would have been helpful in selecting a spring for the proper ride height. In a snowmobile trailer application an inch or two in height makes a bit difference in approach angle when loading a sled. This was about the only measurement not listed for springs so we guessed, and it came out well for us in the end.


These nests are kind of hard to get wrong really. I welded them into position, haven’t thought about them since. So,… I mean,… that’s good right?


Super fast shipping


The only mistake I made was not ordering two axle saddles. I thought my order was for a pair, so I only ordered one. My mistake.


Solid, took a weld like a champ!


Excellent option when the right axle isnt. Fit was great.


Bought these along with the UBolt kit for a Coleman popup camper to do an "axle flip" or move the axle from above the springs to below the springs giving 3-4 inches of additional clearance. My popup has a 1.75" axle and Dexter doesn't make prefab kits for that axle. Spring seats had to be welded to my axle, but beyond that, the axle flip worked OUTSTANDING! If you go off road at all with your camper, I can't recommend enough doing this. Should have done it years ago! Spring seats worked great!



Hey John, Im about to do the same thing to my 89 Coleman pop up. What u bolts did you use and what other items did you need? Just weld these opposite of the old ones and replace springs with u bolt?

John H.


I ordered a couple of the 1- 3/4 U bolts from eTrailer as well. Yes, weld up the perches opposite the old ones but be sure to take some time to make sure theyre aligned both vertically and horizontally. I used a level to compare the top plane of the new perches with the bottom plane of the old ones with the axle upside down and clamped it in place before welding.

Thanks for responding to DC's question. The u-bolt kit that John is referencing is # APUBR-10.


I purchased a number of products from etrailer and I am very pleased with them all. The shipper lost my axle. When I contacted etrailer customer service, they handled my problem quickly and I had a replacement axle in a couple days. Well done!

The products were all of high quality and the assemble was much easier as a result. I have attached a few pictures of the build for those interested.

Thanks etrailer for your great products and service!!

Jim D.


The trailer has performed better than my expectations. The products I purchased are all performing perfectly. When I build my next trailer, I will get all my assemble products from


Exactly what I needed.


Needed "spring over" conversion on Teardrop type camper. Dexter axle required these to do it right. Perfect fit. Time from order to shipping was longer than anticipated. So parts, availability and knowledge are great, delivery time disappointing.

Thom K.


Product is great. No problems whatsoever. I heartily recommend etrailer and will use them for my next camper buildconversion.


Highest quality. These are stout!



A year later and the axle is working just fine. I love the easy lube spindles. So easy and mess free.


The parts that fit the axel where included on the axel page and where just what I needed to adapt the axel to a smaller with trailer


Works as advertised. I had a local welder put these onto the axle for me. I ended up needing them since my harbor freight trailer had a metric dimensional spacing between the mounts and the axle I bought had a standard inches dimensional spacing. They were off by less than 1 inch, but I couldn't make it fit unless I welded on these brackets at the correct location for the trailer.


I have a Coleman Tent trailer and our favorite camp sites are off road. I decided to flip the axle to gain some off road clearances and level the trailer being towed by either my Truck or Jeep which have lift kits. I purchased these parts, installed and I am stoked! Great product and was easy to install. Parts were of great quality and shipped quickly. I will most definitely trust etrailer and highly recommend them. Thanks etrailer!!


Thank you for exactly what I needed at a fair price.
Shipped to me in a timely manner so I was able to the job I was working on.
Your website was very user friendly as well.
keep up the good work.

  • Replacing Harbor Freight Trailer Axle and Mounting on Underside of Leaf Springs
    I recommend getting the correct parts for the axle that you have and not trying to use the parts in the Over-Under Conversion Kit # K71-384-00. The correct Spring Seat # TRSS175 will need to be welded onto your new axle. This will allow you to mount the axle on the underside of your leaf springs. The Replacement U-Bolt with Nuts for 1-3/4" Round Trailer Axles # 175643-Z are the correct diameter for the Dexter Axle # 20440I-EZ-60. The U-Bolt Plate # CE20023G has the bolt hole pattern...

  • Replacement 2000 lb Axle With 72-1/4 Inch Hub Face Spacing
    Although it's not a direct match, I believe with a slight alteration the # 20545I-EZ-72-10 2200 lb axle you'd looked at would do the trick. You'd need to add new spring seats, part # TRSS175 and tack them into place at the correct location and the inside of each tire would sit 1/8 of an inch closer in to the trailer, but unless the clearance to the inside of your tires as already pretty snug, you should be just fine. The axle includes idler hubs with the 5 on 4-1/2 bolt pattern, as well...

  • How to Correct Trailer Whose Spring Hangers Do Not Line Up With Spring Seats
    You will need to have the spring seats removed to have them or new spring seats welded to your axle at the correct locations to match your trailer's hanger spacing. For a 3-inch round axle rated between 5200- and 7200-lbs use part # TRSS300; for a 2-3/8-inch diameter 3500-lb axle use part # TRSS238; for a 1-3/4-inch diameter 2000-lb round axle use part # TRSS175. If you cannot re-position the spring seats to match the hanger spacing then you can have a qualified welder install new material...

  • How to Make a Trailer Axle Over Under Kit for 1-3/4 inch Round Axles
    All you would need for an over-under kit for a 1-3/4 inch round axle would be the U-bolt kit part # APUBR-10 and the spring seat part # TRSS175. You would need two of the spring seats.

  • Options For Replacing An Old AL-KO Axle On A 1994 Pop Up Camper
    The axle in your picture appears to be an old AL-KO torsion axle. We do carry some 72" long round tube axles like the # 20440I-EZ-72. The 72" being measured across from hub face to hub face. The round tube axles are made for leaf spring suspension, so while it may be a suitable replacement length-wise, this would require replacing more than just the axle itself. We do not have any torsion axles here at etrailer. If you are looking for a direct replacement, we suggest contacting an axle...

  • Adding Lift To 2003 Jayco Single Axle Tent Trailer
    I spoke with my contact at Jayco about your 2003 single axle trailer. There is no lift kit available but we may have an option for you. If your 1-3/4 inch axle is round and you have underslung leaf springs, I recommend installing a new spring seat on top of the axle, like the Spring Seat for Typical 2000-lb, Round Trailer Axles, part # TRSS175. Simply flipping the axle is not an option because axles are made with a slight arc so that they can handle the load on the trailer. When placed...

  • Recommended 2000lb Trailer Axle That Measures 53" Spring Center To Spring Center
    I may have an option that works for your trailer, but we do not currently offer a 2000lb axle that measures 53" from spring center to spring center. You can have the current spring seats removed and new ones welded in the correct space for your pop up camper, but you will need to know the hub face to hub face measurement of your current axle as that is something that cannot be changed.

  • Replacement Axle And Leaf Springs For A 4' x 6' Single Axle Trailer
    It is possible to replace your 62" long axle with a longer one. Our next size up is going to be a 72" long 2K rated axle like part # e32GR. The axle being 72" across measured from hub-face to hub-face. This axle comes with 5 on 4-1/2" idler hubs, which will allow for a ton of tire/wheel combos. In order to use our axle you would likely need to relocate the spring seats. We sell them individually with part # TRSS175. From the looks of things, you would need a new u-bolt kit # CE23000 as...

  • Over Under Kit Recommendation for 1-3/4 inch Axles
    I wish we had something we could offer you, but none of the spring seats we offer are designed to fit a 1.9 inch diameter axle. The closest we have is the 1.75 inch spring seat like part # TRSS175 which wouldn't work unless you happened to incorrectly measure your axle diameter and you do have 1-3/4 inch axles. The rest of the parts you would need would come in the kit part # APUBR-10.

  • Can Spring Seats Be Attached On Top of Dexter Axle # 20545I-EZ-72-15
    We do not offer a version of the Dexter Trailer Axle w/ Idler Hubs # 20545I-EZ-72-15 with the spring perches on top of the axle tube but you really wanted to you could have them removed and rewelded onto the other side. Or you could just weld new ones on the side you want with part # TRSS175.

  • Parts Needed to Move the Spring Seat of the Dexter Axle part # 20545I-EZ-60-10
    The axle part # 20545I-EZ-60-10 that you referenced has a 1-3/4 inch diameter and the # K71-384-00 is designed for a 2-3/8 inch axle so that would not work. What you could use is the # TRSS175 as it is a spring seat confirmed to work on this diameter axle. For a U-bolt kit you would want part # APUBR-10. You should have no problem using your current leaf springs with this axle as well.

  • Installing Dexter Trailer Axle T20BTR-7258 In Application Where Spring Seats Need to be Opposite
    Since you need the spring seat on the opposite side of the trailer axle part # T20BTR-7258 that you referenced you'd need to either have the spring seat that's on it removed and attached on the other side of it or have new ones like the part # TRSS175 welded to the opposite side. The bow in the axle allows it to flatten out once the weight of the trailer is put on it. This is why you can't just flip the axle over.

  • Can You Move the Spring Seats on the 2K 60" Dexter Trailer Axle with Idler Hubs
    Correct, you can move the spring seats on the Dexter Trailer Axle with Idler Hubs part # 20545I-ST-60-10 in or out to match your trailer. In order to do so, simply cut the tack welds to free the seat and then tack them back into place where you need them. Please note, you'll also need new u-bolts like the U-Bolt Kit for Mounting 2K Axles part # APUBR-10. If you damage the old spring seats cutting them off you can replace them with the Spring Seat part # TRSS175.

  • How to Determine the Correct Over-Under Conversion Kit
    In order to determine whether you need the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 (2-3/8") or # K71-385-00 (3") you will need to measure the diameter of your axle. If you get 2-3/8" then you need # K71-384-00 and if you get 3" then you need # K71-385-00. As far as tires/rims are concerned you will want to ensure you have a 4 on 4 bolt pattern (which is the most common 4 bolt pattern) I have included a link to an article that can help you with determining this.

  • Parts to Flip 2,000 lb Dexter Trailer Axle With Idler Hubs
    There is a way for you to flip the axles of the Dexter Trailer Axle with Idler Hubs # 20545I-EZ-72-15 you asked about, though the over/under kit you mentioned won't work because this axle is too small in diameter. So while there isn't a similar kit for the 1-3/4" axle tube of the Dexter axle, you can put together the pieces needed, which are the following: - U-Bolt Kit for Mounting 2,000-lb, Round Trailer Axles # APUBR-10 - Spring Seat for Typical 2,000-lb, Round Trailer Axles with 1-3/4"...

    If you are replacing an existing axle, it should not be a very tough job if you select the right components. You can take a couple measurements to be sure you select the right axle for your boat trailer. The measurement you want first is the hub face to hub face distance. You mentioned 60 inches and that is the hub face to hub face measurement for the part # 20545I-EZ-60-15 you referenced. You also said the spring measurement is about 40 inches.

    If you installed a set of spring seats on the opposite of the axle # 20545I-EZ-60-15 you would be able to install the axle in a setup that has the springs either above or below the springs. For spring seats you then would want the part # TRSS175. Some refer to this process as "flipping the axles," but since axle has a slight bow to it you can't just flip them and reinstall them under the springs using the same spring seats.

    Technically the over-under conversion kit can be used with slipper springs if the spring seats are fully welded to the trailer axle and you would have to use a u-bolt plate that fits the springs. Since you have a 2,000 lb axle this doesn't matter since there is not a kit that fits a 1-3/4" diameter axle like the one you have. You can do the same thing with the U-Bolt Kit for Mounting 2,000-lb, Round Trailer Axles - 4-1/4" Long U-Bolts # APUBR-10 assuming you have 1-3/4" slipper springs....

    Trailer axle # 20545I-EZ-72-15 could fit in place of an axle with spring seat center spacing of 57-1/8 to 57-3/8 inches. At the very most the spring seats will have to be cut off and new ones, # TRSS175, welded on by a qualified professional welder for a nominal fee. Another option is an axle-less system, # A20RS545, which is rated for 2,000 pounds and comes with idler hubs. The suspension is built in. With this type of system you will not have to worry about replacing worn suspension parts.

    In order to determine the correct kit for your trailer I recommend measuring the diameter of your axle. The # K71-384-00 is for a 2-3/8" axle. More than likely you have a 2,000 lb axle with a 1-3/4" diameter. You will need to confirm this. Although there is no kit available for this axle diameter you can put one together. What you need is the U-Bolt Kit for Mounting 2,000-lb, Round Trailer Axles - 4-1/4" Long U-Bolts # APUBR-10 along with the Spring Seat for Typical 2,000-lb, Round Trailer...
