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.

Great fit spring seats worked perfectly


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.


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.


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.


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.


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.


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!


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.


Exactly what I needed.


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


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


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.


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.

Thanks for checking All working as needed


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.


Great product for mounting spring on top of axle just remember you have to weld them on

Donald K.


Really happy with purchase great price a only had to buy spring mount pads to mount on opposite side of axle

Donald K.


Love the product have order more for other projects


Worked out just rite, had to setup an over/under to raise trailer. Added about 3" to the ground clearance

Paul M.




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.


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!!

  • Replacement Spring Seats for a 2,000 Pound Trailer Axle
    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. Welding on new ones will be easier. We always recommend that any welding that needs to be done is performed by a professional welder. The spring seat for a 2,000 pound, 1-3/4 inch diameter axle is # TRSS175. These are sold in a quantity of 1. If you have a different axle diameter let me know. We currently have spring seats...

  • How To Get Additional Clearance To Run Larger Tires On Karavan 5 x 8 Utility Trailer
    To change the 4.80x12 tires on your Karavan 5' x 8' utility trailer to ST175/80D13 tires you will need need to have 5-6" clearance between the top of the tire to the bottom of the fender, and 2-3" between the inside of the tire to the frame. The ST175/80D13 is going to be about 3-1/2" taller than your current tires, and about 2" wider than your current tires. Based on the pictures you provided you will likely not have enough clearance without lifting the trailer. Not to worry this is...

  • Availability Of a 2,000LB Trailer Axle With 66-1/2" Hub Face and Electric Trailer Brakes
    While we do not have a axle which fits your exact dimensions we do have the BTR E-Z Lube Spindle w/ Brake Flange # TRU27FR. With 2 of these you can have an axle welded up with 2 Spring Seats # TRSS175 in the dimensions you are needing. Then you will be able to attach the Brakes # AKEBRK-2 and Hub/Drums # 8-173-16UC3-EZ.

  • Center Perch Measurements for Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 72" Long - 2K
    The Trailer Axle with Idler Hubs part # e62YR has a spring center measurement of 58" which is measured from the center of one spring perch to the center of the other. If this does not match what you need, you can remove them via cutting and weld new ones on where you need them using the Spring Seat part # TRSS175.

  • Trailer Axle Solution for 60" Hub Face and 46-1/2" Spring Center Measurements
    I have some possible solutions for your application, but the Trailer Axle with Idler Hubs # e25GR that you were looking at has the 60" long hub face length you're needing but the spring center distance is 48" which is a bit longer than what you're needing and unfortunately the only spring center length we have for the 60" axles. To get this to fit your jet ski trailer you'll have to have a welder cut off the current spring seats and weld on new ones with part # TRSS175. For a standard...

  • Troubleshooting Norther Tool Ultra-Tow Aluminum 5' x 8' Trailer Wearing Inside Edge Of Tires
    Based on the way the tires are rated, it sounds like the axle was over loaded, but I would imagine it has an axle rating of higher than 800lbs. Is there any chance your flipped the axle to get the axle underneath the springs to lift it, but did not weld on new spring seats? That is typically the only time we see this kind of wear, as axles have an arch in them which becomes straight when loaded, but if the axle is flipped and new spring seats are not welded on then the arch will be pointing...

  • Axle And Suspension Recommendation For Utility Trailer
    I think the easiest way to get the parts you need for your trailer is to buy an axle kit that comes with the idler hubs, bearings, races, seals, grease caps, wheel studs, and lug nuts. For the weight you are saying you will be carrying I recommend starting with the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15. This system has a 5 on 4-1/2 bolt pattern so the tire/wheel combo I recommend is the Karrier ST205/75R14 Radial Trailer Tire with 14 inch White Wheel, part # AM32153....

  • Is There 2,000 lb, 72 Inch Axle With Spring Seats on Top
    Nope, you aren't missing anything. There are not any 2k, 72 inch axles with the spring seats on top, just with standard spring seats, like the Trailer Idler Axle Beam # e78GR. What you can do is have new spring seats welded on, which admittedly isn't as easy as just finding an axle with pre-existing spring seats, but it's really the only option. For this use Spring Seat for Typical 2,000-lb, Round Trailer Axles with 1-3/4" Diameter # TRSS175.

  • Replacement Trailer Axle That Measures 60 Inches Hub Face to Hub Face w/ 5-Lug Hubs
    We have an option for an axle that measures 60 inches from hub face to hub face and comes with hubs that have a 5 on 4-1/2" bolt pattern (5 lugs), though it is a round axle as opposed to a 2" x 2" tube. The axle has a 2,200 lb capacity and is the following part number: - Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,200 lbs # e22GR The # e22GR also has spring centers that are 48" apart on center, so you'd need to have new spring seats welded on, the Spring Seat...

  • How to Determine Required Trailer Axle Weight Capacity and Dimensions
    Axle dimensions are fairly standardized. Those we sell are offered in 4 lengths, 57-1/2-inch, 60-inch, 72-inch and 89-inch. We also have axles-less trailer suspensions from Timbren that bolt on to the trailer frame and eliminate the leaf spring suspension completely which can provide excellent ground clearance when that is an important factor. You can see all of our axles on the linked page. For a 66-inch wide trailer you will probably want to use a 72-inch beam axle like # 20545I-EZ-72-10...

  • 2,000 lb Axle Recommendation for 72 inches Length and 58 inch Spring Seat
    Best option we have would be the # 20545I-EZ-72-10 which is a 2,000 lb axle that is 72 inches long from hub face to hub face and has 58 inches between spring seats and comes with hubs that have 5 on 4-1/2 inch bolt patterns. You'd have to also get new spring seats like part # TRSS175 to weld on the other side of the axles since yours mount on the opposite side.

  • Parts Needed for Over Under Axle Kit on 1-3/4 inch Diameter Axle
    I can help you piece together an over under kit that will fit a 1-3/4 inch axle, but the part # K71-384-00 is not a fit for you as it is designed for thicker axles. You would instead want the spring seat part # TRSS175 and then the U-bolt kit part # APUBR-10 and you would have everything you would need.

  • Galvanized U-Bolt and Plate Recommendation for 1-3/4 inch Round Axle
    For a galvanized U-bolt for a 1-3/4 inch axle you would want the part # CE15285GA. For a galvanized plate then you would want the part # CE20023G. The part # TRSS175 is not galvanized since it is weld-on application and welding galvanized metal can be dangerous to breathe.

  • Spring Seat for Trailer Axle that is Getting Moved to Other Side of Leaf Springs
    You'll need to weld new spring seats on the opposite side of the axle so that you can move the axle to the other side of the leaf springs. So since I don't know what diameter axle you have you'd need to measure to be sure. The part # TRSS300 is for 3 inch diameter axles that are normally between 5,200 and 7,200 lb. Part # TRSS350 is for 3-1/2 inch diameter axles like what are 8k axles, # TRSS175 is for 1-3/4 inch 2,000 lb rated axle, and # TRSS238 is for 2-3/8 diameter 3,500 lb axles.

  • Determining U-Bolt Length Needed For 1-3/4" Round Axle When Changing Leaf Springs
    You can determine the correct length U-bolts by adding the dimensions of your axle and components. Knowing that the axle is 1-3/4" round you can add that to the height of the Spring Seat # TRSS175 (9/16"). Then you will need to also add the height of the U-Bolt Plate # 012-040-00 (3/16"), washer and nut (1/2") and your leaf spring (?). Without the leaf spring you are looking at 3". We have the U-Bolt Kit # APUBR-10 that uses 4-1/4" U-bolts that will allow you a leaf spring that is up...

  • Determining If 73" Axle Will Fit 2001 Coleman Utah Pop Up Trailer
    It might, but the only way to be sure would be to measure the current axle installed on your 2001 Coleman Utah Pop Up Trailer. You will need to measure from hub face to hub face, and spring seat to spring seat. As long as the hub face to hub face measurement matches then the spring seats can be removed and welded in the correct location as needed. For example the Dexter Trailer Idler Axle Beam # T20BTR-EZ-7258 measures 72" hub face to hub and 58" spring center to spring center as shown...

    Assuming you are looking for a 2,200 lb axle you can use the Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,200 lbs # e94YR. If you do not need the hubs then we also have the Trailer Idler Axle Beam with Easy Grease Spindles - 60" Long - 2,200 lbs # e43GR. The spring seat measurement on both of these is 48" but there is a solution for that. You will need to cut off the spring seats and add the # TRSS175 to match your 49-1/2" measurement.

    The Trailer Axle with Idler Hubs # e82GR only comes in the underslung configuration.

You will need to following components: Spring Seat # TRSS175, and U-Bolt Kit # APUBR-10. The spring seat will need to be welded to the top of your axle by a qualified welder.

    There is a way to make a 72" 2000lb axle overslung (axle underneath springs) but they are not sold that way. First you will need an axle. I recommend the Dexter Trailer Axle Beam with Standard Spindles - 72" Long - 2,000 lbs # T20BTR-7258 which has the 72" hub face to hub face measurement you are needing.

  • 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.

  • Parts Needed to Mount Trailer Axle Below Leaf Springs
    You can mount the Dexter axle # 20545I-EZ-60-15 below the springs but you would have to weld on new spring seats # TRSS175. These are sold individually. The springs seats that come with the axle are welded to the bottom. You can't flip the axle over because then the natural bow in the axle would be facing the wrong way, the tires would stick out at the bottoms, and the capacity would be diminished.

  • Availability of a 2,000LB Trailer Axle With 60" Spring Center
    The Trailer Axle with Idler Hubs # e32GR is the closest we have to a 60" spring center for a 2,000lb trailer axle. These have a spring center of 58" with a hub face length of 72". It includes idler hubs with a 5 on 4-1/2" bolt pattern. You can have new Spring Seats # TRSS175 welded to the axle in the 60" spring center you need. The axle requires a minimal overhang of 11-1/2" which you would have 12" with a 60" spring center and 72" hub face measurement.
