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.

Thanks to etrailer that’s no more a problem
Bruce Manning Great Springs lifted my trailer 4 inches
Excellent and fast
Fantastic. Trailer rides MUCH better now with the new springs. eTrailer had them to my door FAST and customer services is top notch. You won't find a better price anywhere. I run these on a triple axle boat trailer that is both wide and heavy and they do great. The mono springs are great on saltwater boat trailers so you don't get corrosion trapped between the springs.
Don't use my trailer much but so far the springs have been good.
Steven M - 10/27/2019I recently broke a spring on my equipment trailer. Multi leaf springs are readily available but single leaf for mobile home axles are not. I was happy to find it available at "etrailer". It was delivered in the three days promised and I'm back in business.
Thank you very much! Not a common spring. New spring was exact fit. Springs arrived on Fri, trailer back in service Sat. Will be purchasing more to restore rest of suspension. Nice to have "One-Stop-Shop" for all trailer needs.
I ordered leaf springs on Sunday and had them delivered ground and I received the following Wednesday. I received them in good condition. I will be ordering all of my trailer needs from etrailer. Thanks for the speed and accuracy of delivery.
Webpages were easy to locate the part that I was needing. Check out fast and also easy to navigate. The leaf springs I ordered arrived in less than two days. Appreciate the prompt service
I appreciate the email, the leaf springs are good, needed them to move a trailer about 45 miles to where it currently resides. I dont have time to fill out review BUT will be sure to use yiu in the future now that I know you are so into customer service that yiu follow up with people a YEAR later. That s great. Thanks
Spring was exactly what I was looking for. The pictures with the measurements and video was awesome. Only website I could find spring on and your site was best of all for ease of searching. Thanks!
Very good products and very fix.to me THX.
Antonio - 05/15/2020Put them on haven’t load tested them ye t.
WOW, Can't believe it's been 1 yr. already! So far these have worked out great but I don't tow very often. It's great just having a single leaf there is no rust issues. These fit perfectly & were very easy to install. I would buy again!
Love the single leaf. These last and don't fall apart like the multileaf and allow for a lower trailer. For my use they work great thanks
etrailer is great to work with, have been using them for over 2 years. Products are always as advertised and I have yet to make a return
Just what I needed, when I needed it! The fellow who filled my order noticed I chose an errant mailing choice that would have delayed it...updated me for faster delivery and no extra charge! Keep up the good work, folks!
Just installed today. It was a perfect fit. It replaced a broken one on our water trailer.
Good quality
Have not used products yet but the information found on the website is very helpful and shipping is outstanding.

Arrived just a few days after ordered and is exactly what was needed. Can't wait to get it placed on shack and back on the ice! Thank you!!
