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.
Slipper leaf springs attach to hangers that are welded onto your trailer. The eye of this spring will attach to the front hanger with a suspension bolt. The flat slipper end of the spring will slide into the rear hanger. If you have a tandem- or triple-axle trailer, the slipper end will slide into the equalizer that connects multiple springs. The shape of the slipper end of a leaf spring may vary slightly due to differences among trailer manufacturers. Because of this, it's important to check your leaf spring's slipper end before purchasing a replacement spring.
To mount this spring, you will need hangers, a suspension bolt, and possibly a spring keeper bolt, depending on the design of the rear hanger. If you are simply replacing a spring, you may still have hangers welded onto your trailer, but it would be wise to replace the bolts as they can experience wear. It is also 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.

The Reline trailer suspension fit perfect on my small sailboat trailer. It was easy to install and installation instructions video was great for a first timer like me to do the job. Great customer service support helped me out when the first suspension was too big for my trailer. I return it and got the right size. I am very satisfied with the product and the price on the suspension. 349500
2,000 lb. GVW utility trailer came stock with set of two-leaf springs. No wonder it sagged when loaded to 1,500 to 2,000 lbs. So I ordered a set of four-leaf springs. The description of the springs was very thorough so I was very sure they were what would work and install easily. When the new springs arrived it only took ten or fifteen minutes per side to easily make the switch to the new four-leaf springs. By cleaning all surfaces and going to all steel shorter lock nuts I was even able to re-use the old U-bolts and other hardware. Haven't used it yet (still repairing lights) but I'm sure there'll be a noticeable difference for the better! Thanks e-trailer! 547118

I am very impressed with the whole process from the beginning to the end. I was able to find the 4 leaf spring for my trailer and after comparing ALL the dimension to my broke leaf spring, it was an exact match. It was recommended to replace both sides, so I ordered twp leaf springs. I had several choices of shipping and I select the one that best fit my schedule. The leaf springs arrived on the designated date. The replacement install went flawless because the new leaf springs were an exact part swap out. etrailer.com will always be my first place to look for any parts. 806634

Looking forward to using these on a snowmobile trailer that I'm rebuilding. 785775
Rock solid parts. Easy to all needed components with the online ordering. 785760
These springs were a great replacement for my trailer. The original 1000-lb springs carried the load, but they were stiff with lighter loads. These new springs feature additional leafs that allow the trailer to ride more smoothly with lighter loads, yet remain stable with heavier loads. They were economical and very easy to install, too. One photo shows the difference between my original 1000-lb spring and this product. 735959

I was in need of new flipper springs contacted etrailer and they put onto a great spring it handles my quad wood loads with ease one year later the product is going strong Great team at etrailer just tell them your problem and they will fix it Thanks Brian m 670897
Wow, I had no idea of how bad my original spring were till I installed these. Boat tracks straight behind the truck now which makes it much easier to launch. 662060
I rate the company itself , shipping and parts availability 5 stars. These springs i give two stars. I had to take two sets of leaf spring and make them into one set so they will hold up the trailer. This included complete disassembly , and rebuild of the new springs after installing them the first time. The job took me twice as long. If I had not needed the trailer the next day I would have returned them. These springs are closer to 1500lbs total instead of 2000lbs. 661363
