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 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
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
Exact fit, would be an easy installation only I also replaced the mounts as they were worn so cutting and welding. But all new mounts bolts shackles, should go for many years/miles now. 699964
The springs work great. They fit perfectly and were easy to install. 589839
Parts matched as a pair. Fit and finish good. Prompt shipping 580857
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
Changed 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
I replaced all 4 springs under my 20' trailer and what a difference. Made it like new and at a very affordable price. The tables, charts, diagrams and descriptions given with all etrailer parts makes it so much easier to figure out what is needed and the correct parts. Had the order in my hands in less than 4 days from ordering. This is the fourth, or fifth, order I've placed with Etrailer and I will continue to order from them in the future, as the need arises. The products have been quality, price is unbeatable and shipping is quick. The tech support is also outstanding. Questions answered in a timely matter with a detailed answer and part references. Great Company to deal with. Thanks, Ken 460783
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 - 08/28/2017The springs look good. I am in the process of installing them now. They are the correct ones and fit well. The only miss was on my part. The shackles and bolts should always be replaced at the same time and I should have ordered them with the springs. 557022
The springs were installed without any problems. The wet-bolt bushings pressed into the spring eyes as they should, with no deformation such as what had been the case with the springs supplied with the OEM axle. 608798
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
Well built and quality fit. 784699
Great upgrade to my older stock springs. Great ride while minimizing the sag I had with older springs. Thanks etrailer!! Tony 773974
Better, stronger and decently priced...compared to old leaf spring! 721579
Arrived earlier then expected, great condition. Going to install them this week. Thanks to all. 719338
Bought extra support excellent service 705975
The factory springs on my 2017 travel trailer were horrible. The dealer was no help so I ordered these springs and changed them myself. It made a huge difference. One year later and I am very happy I made the switch. Always great prices and customer service at etrailer. 657926
