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.

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.

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!! 736358

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. 453641

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. 415160

Ask the Experts about this TruRyde Trailer Leaf Spring Suspension

  • Parts Needed to Flip Axle on a Pop up Camper
    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. You may not need...

  • 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.
    view full answer...
  • 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.

  • Does Over Under Kit for 1-3/4 inch Axle Require Welding
    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 that you referenced. You would need two of the spring seats. You will need to weld the spring seats into place.

  • Type of Metal Spring Seat # TRSS175 is Made Of for Welding

  • 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.

  • Getting Extra Ground Clearance and Height on a Utility Trailer
    Since there isn't an over/under conversion kit for the 1-3/4 inch diameter round axles you would need to weld new spring seats, such as # TRSS175, to the top of the axle so you can mount the springs on top of the axle. If this alone does not provide the height needed then you will need taller hangers to increase the distance even more. The tallest double-eye leaf spring hangers we have are # 115919 which measure 5-7/16 inches from the bottom of the trailer frame to the center of the...

  • Recommended Parts for Rebuild/Upgrade of Harbor Freight Trailer
    The Dexter Trailer Idler Axle w/ Hubs - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,200 lbs # 20545I-EZ-60-15 is a great starting point to upgrade your trailer. This will give you a standard size axle with good bearings, hubs, and EZ-lube spindles. This is far nicer than the weird sized stuff that comes on Harbor Freight trailers. The Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel - 5 on 4-1/2 - Load Range D # AM31994 will be a great addition to these hubs...

  • Is There An Axle Flip Kit for a 2,000 Lb 1-3/4 Inch Diameter Axle
    I do have all of the components you will need to flip the axle on your tent trailer but there is not an all inclusive kit per se to do so. However, the kits are pretty basic as all they include are u-bolts, tie plates, and spring seats. For your 1-3/4" diameter axle, I recommend using the U-Bolt Kit part # APUBR-10 with the Spring Seat part # TRSS175 (2). The only difference between these two parts and a kit like the Dexter Trailer Springs Over-Under Conversion Kit is that the spring seats...

  • Replacement Axle for Harbor Freight Utility Trailer
    Since you want to change your trailer hubs to the 5-on-4-1/2 bolt pattern I suggest you select a 60-inch axle kit that includes idler hubs, such as one of the two kits shown on the linked page. These two 2K-rated axle kits include 5-on-4-1/2 hubs, bearings, races, seals, lug nuts and bearing grease. Kit # 20545I-ST-60-10 works with 8- to 10-inch wheels and kit # 20545I-ST-60-15 works with wheels from 12- to 15-inches diameter. If you trailer's existing axle is installed below your leaf...

  • Can an Axle Over Under Kit be Made for 1-3/4 inch Trailer Axle
    If you are okay with removing the fenders or going to a larger one that would probably be your simplest route and the way I would go if I were you. We don't have an axle over under kit for your axle size, but we could piece together one if you like. 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. Then for a 14 inch wheel and tire we have the part...

  • Can Leaf Springs be Mounted Below Trailer Axle # 20440I-ST-72
    All you have to do to mount the leaf springs to the bottom of trailer axle # 20440I-ST-72 is to weld on new spring seats to the bottom of the axle. 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. Dexter does not recommend using the over/under conversion kits...

  • 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.

  • 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....

  • 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.

  • 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.

  • Parts Needed to Do an Over-Under Kit on a 1-3/4 inch Trailer Axle
    When you use an over under kit like the part # K71-385-00 you end up gaining a lift that measures the diameter of your axle, plus the spring seat, and the thickness of your leaf springs. You will need to measure those items on your trailer to determine the amount of lift you would need. Since we don't have a kit designed to fit a 1-3/4 inch diameter axle, and since you aren't completely sure that is the diameter of your axle you will need to verify this before I can piece you together...

  • Can Leaf Springs be Mounted to the Top of Dexter Trailer Axle # 20440I-EZ-60
    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.

  • 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.

  • 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...

    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. This is important because the spring-center-to-spring-center...

  • Adding a Brake Axle to a 48 Inch Wide Home Made Travel Trailer on Harbor Freight Frame
    What you could do is use an axleless system # A35RS545E which comes with everything except a brake controller. The only issue is that you would need to also replace the tires and wheels with something like # AS13B45SMQ since the kit has a 5 bolt pattern and your trailer has a 4 on 4 pattern. We don't have a straight axle with the proper spring hanger spacing for the trailer. But you could potentially use # T20BTR-6048 and have a professional welded cut off the spring seats and weld on...

  • Parts Needed to Install 2,000 Pound Round Axle Under Leaf Springs
    In order to mount the round 2,000 pound axle under your trailer's leaf springs, we will need to piece together an over-under kit for the 1-3/4 inch outer diameter of the axle. The Dexter Trailer Springs Over-Under Conversion Kits that you referenced are made for axles with a 2-3/8 inch round axle # K71-384-00 or 3 inch round axle # K71-385-00. The Dexter 2,200 pound straight axles have a 1-3/4 inch outer diameter. I have attached a link to all of the 2,000 pound axles we offer. To mount...

  • 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.

  • Can Dexter Trailer Idler Axle Be Used on Trailer With Springs that Sit On Top Of Axle
    The bend in the axle needs to be installed pointing upward, not down. If the axle is installed with the bend going toward the ground instead of toward the underside of the trailer, it will cause the camber of the wheels to be wrong. Since your springs touch the top of the axle instead of the bottom, you will want to have new spring seats welded to the top of the axle. For an axle with a 1-3/4 inch diameter like # 20545I-EZ-72-10 that you referenced, you will want a spring seat designed...

  • 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.

    I have a solution that will allow you to flip your axle but there is not an all-inclusive kit for your axle size so we will need to piece together one. I assume you have a 1-3/4" diameter axle (1,000 lb - 2,000 lb) so that means you will need the U-Bolt Kit part # APUBR-10 and the Spring Seat part # TRSS175 (2). These u-bolts are 4-1/4" which is the longest we have for this width. However, I would highly doubt that you will require a 6" long u-bolt as most leaf springs are only 3/8" thick....

The Dexter Kit # K71-385-00 is a fit for 3 inch diameter axles. For 2-3/8 inch diameter axles, you will want the Dexter Kit # K71-384-00.
