Video Transcript for TruRyde Trailer Suspension TRSS238 Review

Today we're going to be taking a look at this spring seat for typical 3,500 pound round trailer axles with a 2 3/8" diameter. The spring seat is a necessary component of your trailer suspension system when mounted with a 1 3/4" or 2" wide leaf spring. It adds extra support and provides proper positioning for the axle. It's made from a durable steel construction. It would weld onto a 2 3/8" diameter axle which is a typical 3,500 pound axle. It sits on top of a 1 3/4" or 2" side leaf spring. The cutout on the flat side would surround the raised knob on the leaf spring to prevent turning in or shifting.

It simply provides that 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 starting with the overall length. It's going to give us a measurement of 4" long. Overall width, it's going to measure about 1 7/8" wide. Height is about 1 1/4" tall, and this opening right here of this rounded area at the widest point, that's going to give us a measurement of about 2 1/8".

That's going to do it for today's look at the spring seat for typical 3,500 pound round trailer axles with a 2 3/8" diameter.

When I recieved the product I was ready and excited to get it installed. I had to do an axle flip to gain frame clearance on my custom jeep trailer build and needed new axle perch mounts. After I triple stitch welded the steel It was a perfect fit, and a year later no problems and holds great.

2 3/8" spring pads, welded on. Were great for swapping axle over to axle under setup. Achieved 5 1/4" lift making my fifth wheel taller. Tall enough for a newer truck with taller stance.

I bought springs, mounts and Tailight kit to fix up a rusty utility trailer. I cut, weld scraped and painted for the better part of a month in spare time. The springs and mounting instructions on e trailer are excellent. Only issue/shortcoming are the tail lights. Wire just pushes in and spring loaded strip holds them. I soldered and sealed the connection with silicone. So far that salt covered roads haven't hurt it in winter. The folks at etrailer are very helpful and prices are a good value.

I used the seats to reposition my springs from the lying under the axle of my TT to sitting on top of the axle. This gave me about 4.5 in of additional much needed ground clearance. The cut and sizing of the seats was spot on and made for and easy axle flip. I opted to use these and the U-bolt and plate kit instead of the Dexter spring over kit and saved about $50. I did the entire job start to finish in 3 hours. One thing to note is that if you are looking to flip the position of your axles from the top to the bottom like I did. You are also going to have to lengthen your brake lines also.

Very satisfied with the product. I recently purchased 2 new dextor axles locally which came with springs mounted underneath. My application required the springs to be mounted on top of the axle and so I intended to remove the springs, flip the axles over, and bolt the springs back on. Unfortunately I realized this could not be done due to the axle tube being factory cambered (bent slightly upwards) and so i then searched and found these spring seats at a reasonable price and fit perfectly. It was by far easier to leave the original seats in place as guides and weld these new seats on. Also of note these seats are slightly larger than the factory Dextor seats. Thank you etrailer.com for a great product and quick shipping.

These are an awesome upgrade to your trailer with 13" tires These went on a Coleman tent trailer. This is the big one with all the stuff making it heavy. The old load range C tires look like it was run on the sidewalls of the tire as the trailer is heavy. The new load range D tires with the extra 15 psi (65) made the difference. Looks normal now. I also ordered the 3,500 axle leaf spring perches. Going to weld them to the top of the axle to mount the springs above the axle. This gains 4.25" lift. Needed as it drags just going out of the driveway lol

The set of springs I purchased for a dump trailer definitely fixed the problem of one broken spring and one very worn out spring. The springs, axle u-bolts were all the perfect fix and replaced perfectly. Ordering another set now AND a rear axle I was so pleased with the outcome. Thanks etrailer!

Rebuilding a home made trailer, we used it to haul large round bales. Needless to say was getting pretty rough. We are planning on using it to haul our UTVs now so we are down grading from a 15000 lb trailer to a 10000 lb trailer. We purchased 3 used 3500 lb axles and with the kits we purchased from you it has made the swap over very easy, everything fit prefect, Thanks

Ask the Experts about this TruRyde Trailer Leaf Spring Suspension

  • Is Trailer Axle Spring Seat # TRSS238 Sold Individually or in Pairs
    The trailer axle spring seat part # TRSS238 is sold individually. If you needed two of these you'd need to order a quantity of 2.
    view full answer...
  • Where on Axle Should Spring Seats Be Welded On
    The bend in an axle (the top of the arch) should be at the top of the axle so that as the trailer load is placed on the axle it flattens out. The spring seats # TRSS238 should be welded to the underside as shown in the linked diagram.

  • When Moving Leaf Spring Above Axle Can U-Bolts be Reused
    If your U-bolts are still in good shape you could reuse them. You would just need a new spring seat designed for your diameter axle. I attached a link to a page that has all of the spring seats we carry. If you select your axle diameter from the filters on the page the correct one will be listed.

  • Does Trailer Spring Seat Need to be Welded to Axle

  • Do Old Spring Seats have to be Removed to Move Springs On Top of Trailer Axle
    You do not have to remove the old spring seats unless they cause a clearance issue. But keep in mind that the new spring seats will have to be welded to the axle. Welding should be performed by a qualified professional with experience working on trailers. If you were to use an over-under conversion kit, # K71-384-00, you would not have to do any welding.

  • Can I Add Spring Seats To a Different Mounting Location On My Dexter 3,500LB Axle?
    Yes, you can weld on new Spring Seats # TRSS238 to your Dexter axle. It is important to ensure that the springs seats are welded onto the axle with the correct axle orientation. The axle does have a top and bottom as well as a front and a rear. It is a good idea to place the axle where you are going to need it and ensure that it is centered and square on the trailer before fully welding on the new seats.

    I reached out to my contact at Dexter and your current axle has a hub face to hub face measurement of 88.58" and a spring center to spring center measurement of 68" with an axle capacity of 3500lbs. The closest replacement option we have is the Dexter Trailer Axle Beam with Standard Spindles-3500lb # T3584F-8974 which has a hub face to hub face measurement of 89", and a spring center to spring center measurement of 74" as shown in the included diagram.

    The best option we have for you is going to be with the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles part # 7685269 which has a 3,500 lb weight capacity. This will allow the tires to extend out past your load and will provide you with the low load height you will need. The spring center spacing on this axle is set at 80" but if this does not match what you have on your trailer now then you can always move them to where you need them with part # TRSS238.

You can choose one like # 7359765 and then weld on spring seats like # TRSS238 at 78 inches on center. Another option is to use an axle-less system like the Timbren # ASR3500S05. This allows you to add both the spindle and the suspension with a simple bolt on installation. If you aren't right...

    The correct replacement 3,500 axle with 95" hub face measurement is the Dexter Trailer Axle Beam with E-Z Lube Spindles part # 7359765. The spring centers are 80" apart so you will need to remove them and tack weld new spring seats in the locations that you measured using part # TRSS238. Please note, the spring center is measured from the center of each seat. The hubs are not the same for a 3,500 lb and 7,000 lb axle.

This axle's diameter is 2-3/8-inches so you can use spring seat # TRSS238. These seats are compatible with 1-3/4-inch wide or 2-inch wide leaf springs.

You could go larger in weight capacity, up to a 5200 lb axle like # 8327820-EB, but if your current axles are 3.5K apiece, increasing the capacity of the axles won't increase the trailer's...

Both axles are 3,500 lb leaf spring tubular axles, but they are different lengths. The Dexter axle is slightly longer, which means the wheels would stick out further and the spring center is wider.
