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.

Great upgrade to my rusty worn out spri ngs 605596
I have been buying products from etrailer since 2009. I come back because the customer service in helping me find the right part or return a part is always, year after year, excellent! I needed 6 leaf springs for my toy hauler and couldn't find a part number. I called and Sandy helped me find a great replacement spring. I needed the springs quickly so we could go on a planned trip. Ordered them Tuesday, they arrived Thursday in perfect condition. I installed them and wow, the ride height restored, the camper sits square and wheels all straight. THANK YOU Sandy and etrailer. I will keep coming back. Michael 403680
Fit perfect for my Rv. 577492

Great looking springs! Just what I want ed. 462635
The products I brought are exact and fit perfectly. The shipping was great, fast. 289431
So happy with my purchase. Made a huge difference. I went one size up in weight capacity on my 28’ fifth wheel. Tows and sits a whole lot better and more sturdy. Paired with my new brakes I bought from etrailer It’s a whole new experience towing my trailer. 100% for the better. I recommend these. Especially for the price 640233
I ordered these to replace 4400# springs on our fifth wheel that are 10 years old. I was expecting the ride height to increase but it did not. They appear to be of acceptable quality but as with most products time will tell. We haven't used them yet but are planning a long trip next month. 286904
Randy R - 08/28/2017Changed out 4 broken springs for 4 new ones. They were a perfect fit and pretty easy to change. As far as customer service is concerned I wasn’t on the phone for more than 5 minutes and springs were on the way. I will definitely use etrailer again on my upcoming boat trailer project!! 597283
Total refit. Three axles, six springs, all pivot point bolts, bushings and link plates. Excellent pricing (the best I found). Super quick delivery, like three days. And free shipping on an order weighing close to fifty pounds? Best of all the company followed up a year later to see how it went. It went great, which why I'm writing this review. Quality, fitment, price, delivery, support. Five stars. 719659

Was very happy to find this product at etrailer. Locally I was told that these springs were almost impossible to find because of the covid shutdown. I ordered this item and they arrived at my door step in a very short time. Swift responsible handling of my order. Without a doubt I will be back. 894689
Fit perfect. Installed the pair in about 1 hour and 20 minutes. That included cutting the old set off 887361

Perfect, Quick shipping 866090
My 36 ft travel trailer was sagging 3-4" low on the drivers side. The problem was those 2 springs were flatter than the passenger side. It was noticeably lower. I jacked the frame up and installed the springs one at a time, didn't have any real problems. Installation for 4 springs took a couple hours, TT is setting level now. Great product. 864396

Had to replace a broken leaf spring on an older dump trailer. Having previously purchased products from etrailer I looked at their website first. Quickly found what I was looking for and made the purchase. There was also helpful information on their site to insure I ordered the correct springs. 809457
I have yet to install the springs but am amazed at how easy the ordering process was and also how quick delivery was handled!! Thanks! 801621
