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.

good product 735125
The left leaf spring on my Dilly 3 rail motorcycle trailer broke. These springs cannot be welded because the steel carbonizes. I ordered 2 replacemeny slipper leaf springs from etrailer. They fit beautfully, just had to slightly increase the diameter of the hole in the axle so that the bolt/nut in the center of the spring would fit. Etrailer has always delived a quality product over the years to me. 718141
Work fine. Had to open the holes on the trailer for 9/16dia. mounting bolts. The trailer is from the 70's, and the 1/2 mounting holes were already wore larger so a 9/16 drill worked easily. 713928

Excellent no issues shipped easily and installed just as easy Thanks 557017
These leaf springs are amazing! I purchased two springs that replaced the old leaf slipper springs on a single axle toy hauler trailer. The measurement from the eye bolt to the end of the slipper spring was 29 1/4 inches. My old springs measured 32 inches because they were so worn and the 30” leaf slipper springs worked perfect! 529263
