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.

The spring seat is a necessary component of your trailer's suspension system. When mounted with 1-3/4" wide leaf springs, it adds extra support and provides proper positioning for the axle.


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.


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 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.


Excellent customer service as always. These guys and gals have all the right answers when I hit a few snags on my Tow Dolly and boat trailer repairs. Thanks


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.


Exact replacement


Highest quality. These are stout!


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!!

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
Jim D - 01/02/2021


Good product, looks about best quality made, functional. I foresee no problems using thes3 downrange.


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.


Thanks! Arrived early.


Quick delivery


These worked perfectly to give me the lift I was looking for on my trailer. I’ve dragged the trailer all around Florida and to Texas and back with no issues. Wouldn’t think twice to buy again


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?
-- comment by: DC - 06/02/2015

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.
-- comment by: John H - 06/05/2015

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

-- Etrailer Expert Rachael H - 6/8/2015


make sure you order two if doing a spring over conversion. The ubolts come as a kit the seat (TRSS175) does not. ORDER TWO!!!


Very satisfied with the quality of the local welder had no difficulty
Mounting on axle. Holds up well after a year


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.

Product is great. No problems whatsoever. I heartily recommend etrailer and will use them for my next camper buildconversion.
Thom K - 07/07/2015


Seems like quality metal. Was easy to get them welded on. Confirmed great to my 2000 lbs axle, no issues.

Everything is still great, no issues.
Shawn - 04/14/2021


Perfect fit, no vibration, durable. Held up to off road use in west Texas scrub!


easy install, no issues after a year in use


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!!


seats were easy to weld to axels

seats still working-see no problem ever with them

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.

Jim J - 08/05/2016


Did a spring over conversion on a pop-up camper, with larger wheels. Easy and gives me a lot more ground clearance. Had to slam through a hundred yards of deep, greasy clay mud out by Chaco Canyon in NM after a big rain. All went well.

Ask the Experts about this TruRyde Trailer Leaf Spring Suspension

  • Can New Spring Seat be Installed on Axle if Current Seats Don't Line Up
    Yes you can weld new spring seats to your axle so that it matches your trailer frame if you ordered the wrong size. For 1-3/4 inch spring seats you would want the part # TRSS175 that you referenced.
    view full answer...
  • Type of Metal Spring Seat # TRSS175 is Made Of for Welding
    The spring seat part # TRSS175 that you referenced is made of steel like what your axle is made of so it would not be an issue for you to weld at all.
    view full answer...
  • Do Trailer Axle Spring Centers Have to Match Perfectly
    If the spring seat dimension on the axle does not match up the suspension won't work properly as it will be bound up instead of able to move freely. This also would cause premature failure of the components as well so I'd have to recommend you reinstall them in a better location.

  • Are Axles Available Without The Spring Seats Installed
    The axles we offer have the spring seats already installed and they are placed at one of 3 lengths, 48 inches, 58 inches and 74 inches apart. You would have to install new spring seats if you need the distance to be 53 inches. I have attached a link to the spring seats we offer. You will want the spring seats to be welded in place by a qualified welder.

  • 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...

  • Can Spring Seats On Trailer Axle Be Moved To Match Trailer Frame?
    They sure can! What you will need to do is replace the spring seats that are currently welded on the axle in question, and have a qualified welder weld them in the correct location to match your trailer. Now the correct spring seats will be dependent on the diameter of your axle tube. The most common sizes are the 1-3/4" # TRSS175 which is common for 2000lb axles, the 2-3/8" # TRSS238 which is common for 3500lb axles, or the 3" # TRSS300 which are common for 5200-7000lb axles. I included...

  • 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...

  • Can Trailer Leaf Springs be Moved from Below the Axle to the Top of the Axle
    Some trailers have the leaf spring stack above the axle and some have it underneath. You can move the stack to the top of the axle but you will have to weld on new spring seats to the top of the axle. Use # TRSS175 for a 1-3/4 inch round axle. It will raise the height of the trailer some but you need to be aware that it also raises the center of gravity. That makes the trailer more susceptible to sway.

    I have exactly what you need, but it will have to come in the form of a couple parts pieced together because an over-under conversion kit or "axle flip kit" as some people call it isn't available for the smaller 1-3/4 inch round axles. To move your leaf springs above your axles, you will want the following parts: Qty 2 - Spring Seats # TRSS175 Qty 1 - U-Bolt Kit # APUBR-10 The spring seats will be welded to the opposite side of the axle as the current spring seats.

  • Parts Required to do Over/Under Conversion on 1-3/4 Axle on Tractor Supply Trailer
    From what I was able to determine the Tractor Supply trailer you have likely has a 2000-lbs axle on it, which has a 1-3/4" diameter axle. There isn't a specific over/under conversion kit for that size axle but you can use 2 of the spring seat # TRSS175 and weld them on either end of your axle and then use the # APUBR-10 u-bolts you were looking at to complete the process. It should be noted that you need to have a qualified welder perform the installation of the 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....

  • 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.

    You should not flip an axle upside down because axles have a bow in them at the center which helps give them their capacity. But all you would have to do is weld on new spring seats to the top of the axle. For axle # 20440I-EZ-60 you would need 2 of spring seat # TRSS175.

    Since we do not have a close enough match for what you are looking for in an axle the best solution is to move the springs seats were you need to or weld on new ones.

    Yes! You can weld the springs seats to a different location on Dexter trailer axle # 20440I-ST-60. But instead of cutting off the ones on the axle and welding them back on I recommend getting new springs seats, # TRSS175 (sold in quantities of 1), and welding them on in the proper position. This will ensure that the springs seats are in good shape.

This axle has a 1-3/4 inch outer diameter so you would need 2 of spring seat # TRSS175. Welding should be done by a professional welder. Trailer suspension needs about 3 inches of space to travel so if there is not enough space then you would also have to use taller hangers.
