Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.


Leaf springs are an integral part of your trailer suspension system. The leaf springs provide the attachment points for your trailer's axle, suspending it from the frame of your trailer. Each spring flexes to absorb road shock as you travel, allowing the axle to move somewhat independently of the rest of your trailer. This helps to reduce wear and tear on the trailer and also ensures a smooth ride.


Double-eye leaf springs attach to hangers that are welded onto your trailer. One end of this spring will attach directly to the hanger with a suspension bolt. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs.


To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your trailer. You should, however, replace your shackle straps because they are usually the first component to wear out. You may choose to replace old suspension bolts as well. It is recommended that you replace the other leaf spring in your setup at the same time. Because springs can sag and elongate as they wear, this new spring may not exactly match the old one, and the alignment of your trailer could be affected.


If you are fabricating a trailer, you will need to purchase a hanger kit for installation. To determine the type of hanger kit that you need, you must know the specific type of leaf spring that you have, as well as your axle capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications. Hangers and other suspension components can also be purchased separately if there isn't a complete kit that works for your setup.

I found the site to be informative and detailed to enable me to make the best/correct order. Better than that was the prompt shipping and receipt of the Leaf Spring that will enable use to get back to camping very soon. I received the Spring prior to the estimated delivery date.

Thank you etrailer for getting these springs quick,fast and in a hurry!
Much appreciated!
Good website with product description that makes it easy to be sure I’ve ordered the correct part.




by:

I had a trailer spring break this summer on the way home from a 2,700 mile trip. Our small luggage trailer just couldn’t take anymore rough roads. One of the springs broke through the centering bolt. The etrailer.com website and Tammie P. came through with replacement springs and accessories. Thank you Tammie P. And trailer.com!

Great leafsprings great fit . Very fast shipping. Thanks alot

Still on great shape and working fine
David - 11/05/2017


by:

The diameter of existing bushing is bigger than the 11/16" spec (see my review of bushing purchased at same time). The bolt holding springs together is too long. Had to cut excess down to but acid grind some of nut off. As with my bushing comment I was promised a tech rep would call me right back and no one ever did.


Comments
Jim, I apologize for any inconvenience with your order. I see that Wayne of our office called and left a message to resolve this issue.

by:

As you know from my order I changed the entire suspension on my 1996 Terry fifth wheel. I found your website ease to navigate and order what I needed. Your pricing was not overly high and your shipping was fast. Now with my new suspension I should get another 23 years of use out of my trailer. Thank you.




by:

Bought 4 leaf springs, bolts, bushings, etc... Needed it next day, and the shipping cost more than the parts, which tells me the parts were a great price. All was well, on time, and to order. The only problem was I should have ordered two more shackle bolts... but that's on me. Thanks Guys and Gals. I am a happy 62 year old Marine Vet back on the road!




by:

Everything works great




by:

Kind of hard to rate at this time. Only time will tell how good they are. I didn't catch it in time but, these springs have only the plastic bushing in the eyes with no rubber bushing for cushion like some Iv'e seen. Made in China but what ain't. They seem to be a good spring and I'm sure they'll work fine. Excellent service.




by:

I ordered a pair of leaf springs for my boat trailer. I received them two days sooner than expected and they are an exact match. I am very happy with the product and service I received from (etrailer.com).




by:

Package showed up quickly and was exactly what I wanted.




by:

Excellent delivery time , product came as advertised however I ordered the wrong part number . I needed a heavy spring as our axle is 3500 pd not 2000 but put in another order as soon as I can .
Thank you for providing good products, great delivery time and fair prices.
Be Blessed




by:

springs fit well and are the right rating for my small sailboat. The only downside is that I'm seeing rust beginning already on the spring finish. They need to do more with the protection/weatherproofing coatings.




by:

All the products I have purchased are exactly what I ordered and delivered right on time. Always great products and service with eTrailer.com.




by:

As usual, etrailer came through with the springs Ineeded when no one else had them. Second order from them (fast shipping to).
Will use them for any trailer items.




by:

Super fast shipping springs were just what I needed found lots of information on etrailer website on how to measure also great seller will be using them again when needed




by:

Leaf spring was exactly as described. Fit trailer perfectly and was easy to install. Shipping was quicker than expected. Satisfied to the point I ordered 2 more for a older trailer I have.




by:

We are still in the process of building the wagon, but are very happy with the products we received.




by:

Worked very well. Handle the load great.

  • Available 23-1/2 Inch Replacement Double Eye Spring
    We carry one 23-1/2" double eye spring, # SP-113275. This spring is for a 2,000 lb axle, has three leaves, a spring width of 1-3/4", an eye diameter with bushing of 9/16" and an eye diameter without the bushing of 11/16". I've added a link to a video review of this spring for you to take a look at.

  • How To Determine Hanger Spacing for Single Axle Trailer Suspension Based on Leaf Spring Length
    The trick for hanger spacing is to subtract around 3/8 of an inch from the spring length (eye to eye) and then use that dimension for the hanger spacing on a single axle trailer. So for a 23-1/8 inch long leaf spring a spacing of 22-3/4 inches would be the correct dimension to use.

  • Can Center Bolt Be Ran from the Bottom Up on Trailer Leaf Spring # SP-113275
    Yes, if you look closely at some of the pictures you can see the center bolt for leaf spring # SP-113275 goes through the stack and into a nut on the bottom. So in other words it can be reversed. Please note it would be a good idea to secure the spring using vises or clamps in order to keep the spring stack in position and so no residual tension can cause a leaf to possibly cause an injury. Do not work on springs when they are under load (still on the trailer).

  • Replacement 23.5" Leaf Springs and 5.3 X 12" Tires for Utility Trailer
    Reshaping leaf springs is not advised. This will weaken them and potentially cause them to fail. The Universal # SP-113275 Double-eye spring for 2000 pound trailer axles has the 23.5” length you were wanting. I would replace both springs at the same time. I have attached a link to this product page and a video review. Regarding your tire failure. There are many reasons why you could experience tire failure, which includes operating them under greater loads than what they are designed...

  • Leaf Spring Recommendation for Canoe Trailer
    A canoe trailer would take a lighter duty spring which for that our lightest option is for a 2,000 lb axle which the closest size we have to what you'd need is the part # SP-113275. You'd have to move your hangers to allow this to fit though. Your size is an unusual one and not something we have. You'll need new suspension hangers too which I attached link to all that we offer.

  • Trailer Suspension Hanger Spacing for a Single Axle Trailer and 23-1/2 Inch Long Spring
    On a single axle trailer the hanger spacing is approximately 1/2 inch (or slightly more) shorter than the spring length. So if your spring is 23-1/2 inches long, such as # SP-113275, then you are looking at a hanger spacing of 23 inches on center. The shackle length you use depends on the hanger height from the bottom of the trailer frame to the center of the eye hole. You would want the spring eyes to be level so a shackle that is too short or too long would throw that off. I have included...

  • What Causes a Trailer to Bounce
    A trailer can bounce if there is not enough weight on it. You see this particularly with utility trailers that are empty. The tire and wheel size would not automatically cause a trailer to bounce though usually you see smaller tires on smaller trailers and smaller trailers tend to be light weight. So again it really comes back to weight. It is also possible that there is too much tongue weight and/or the trailer is being towed nose down. This would limit the weight that is over the axle(s)...

  • What Kind of Steel are Trailer Leaf Springs Made of
    The steel of the trailer leaf springs like part # SP-113275 is spring steel which is designed to flex and go back to it's original shape. Spring steel is typically low-alloy manganese, medium carbon steel.

  • Troubleshooting Front Wheels Lifting on Dual Axle Trailer
    It sounds like your shackle straps are binding or flipping and this should not be, so you will want to determine the cause of your suspension issue. It could be shackle strap length, equalizer length, or leaf spring length causing the issue. I recommend having it looked at because an axle off the ground and slamming down will cause damage over time. I've attached an article on suspension to assist.

  • Center Bolt Size on #SP-113275 Leaf Spring
    3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 23-1/2" Long # SP-113275 doesn't have a traditional bolt but it does have a threaded shaft and nut on the bottom. It is more like a plug on the top for the spring seat of your axle to rest. The length is 1-3/4 inches overall and it is 3/8 inch diameter by 20 threads and sticks out 1/2 inch from the bottom of the spring stack.

  • Correct Replacement 23-3/4" Long 3-Leaf Spring for Trailer
    It's common for trailer leaf springs to stretch a bit as they age so the correct replacement for your trailer is the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles part # SP-113275. This leaf spring has three leaves that each measure 1-3/4" wide, just like your old so it will be a direct replacement for your trailer. Please note, it's recommended to replace the leaf springs in pairs.

  • Determining the Correct Leaf Spring Length for Trailer
    There is no exact way to determine the leaf spring length. The best way to determine the length for a replacement is by measuring the existing leaf springs. The hanger distance and shackle length can help you get a good idea, but you're looking at an approximation. Those leaf springs appear to be in good shape, so assuming they are factory leaf springs I would continue to use them. When installed, the shackles in the rear should be in a position that will allow the suspension to move....

  • Replacement Leaf Springs for Trailer with 24 Inch Long Double Eyed Springs
    I'll start this off by saying that often times when springs are worn, they will flatten out and get longer when measuring the distance between the eyes (make sure you are measuring the distance when the springs are unloaded- you will need to jack the trailer up or remove the spring altogether); additionally, the other thing to consider when choosing replacement leaf springs for your trailer is the capacity of the trailer. The number of leafs in the spring is not nearly as important as getting...

  • Determining Hanger Spacing for Replacement Leaf Springs on Trailer
    The closest leaf spring set we have available to the 22-1/4 inch length you mentioned is the 3-Leaf Double-Eye Spring # SP-113275. This double-eye leaf spring features a length of 23-1/2 inches from the center of the spring eye to the center of the other spring eye. I recommend making sure you are measuring your existing leaf spring from the center of one eye to the center of the other. This particular set is designed for 2,000 pound axles, so you will want to also make sure any new springs...

  • Recommended Trailer Springs for my 2,000 lb. Axle with 20-1/2" Mounting Hole Centers
    Instead of changing the geometery of the original design which could cause issues the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles part # SP-169275 has the exact same specifications as the one you have however it has a 20-3/8" center to center on the holes. This is likely the same one you have but over time yours has worn out a bit and has lengthened. We often see this as springs get worn out.

  • Upgrading Travel Trailer Leaf Springs to a Heavier Duty Option
    To upgrade you current leaf springs, you will need to up their capacity to that of a 3,500 pound axle. The Universal Group 3 Leaf Double Eye Spring # SP-216275 is the replacement I suggest. It measures 23 1/8 inches long from eye to eye and is the closest we have to your current spring. Each spring is also rated to 1,750 pounds giving you a total capacity of 3,500 pounds per axle.

  • Replacement Leaf Springs for 1991 Fleetwood Prowler Limited
    It sounds like the old springs might be 23" long on your 1991 Fleetwood Prowler. In order to determine which leaf springs you'll need as a replacement you will need to know the capacity of the axle, the rough length of the spring (which it sounds like you already know) and the way the spring is mounted (double eye or slipper). You can determine the capacity on the axle by checking the sticker/plate on the center of the axle. When it comes to springs that are roughly 23" long, there are...

    The best way to choose the correct replacement leaf spring for a trailer is to measure the existing spring. If this cannot be done however then you can get a good idea of what the spring length will be based on the hanger spacing but this is not as exact as the length of the shackle comes into play as well. If you measured the leaf springs hangers on center then I recommend using the 3-Leaf Double-Eye Spring part # SP-113275 which is 23-1/2" long. I'd also recommend the Single-Axle Trailer...

    The 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 23-1/2" # SP-113275 is rated for 1,000lbs each, and since there are two springs per axle the weight capacity would be 2,000lbs per axle. This would not be sufficient for your 5,500lb trailer so you would want a heavier duty leaf spring. I see you ordered 4 of these leaf springs which tells me you likely have a tandem 2 axle trailer. This means each leaf spring must be rated for a minimum of 1,375lbs to be sufficient for a 5,500lb...
