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.

Hello everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the etrailer five leaf slipper spring with the radius end for a 10,000 pound trailer axle. Now this leaf spring will act as part of your trailer suspension system, provides the attachment point for your trailer's axle. This uses multiple leaves to allow flexibility to absorb road shock allows for a nice smooth ride and it reduces wear and tear on your trailer. It'll even help ensure level ride on bumpy and uneven surfaces.
It is a sturdy steel construction. Now there is a rubber bushing with a steel sleeve that's pre-installed on the eye end. The eye diameter of that steel sleeve is three quarters of an inch. Now the premounted hangers are aftermarket hangers, which are required for installation. Those we do sell separately on our website.
Basically the eye of the spring here attaches to a hanger that's mounted on your trailer frame and the slipper end will slide into a hanger or an equalizer. This is for a quantity of one leaf spring. The number of leaves on this one is five, and it has a spring capacity of 5,000 pounds. So when it's matched with one on the other side of the axle, it'll meet the axle capacity of 10,000 pounds. Now the length of the spring is always measured from the center of the spring eye to the end of the spring when it's unloaded.
So on this one, if we go center to the end, you can see is right at 30 and a half inches. The width on the springs are two and a half inches. Now there are more dimensions listed on the product page in case you need them. One note I do wanna mention is to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs and we do recommend installation by a professional. But that should do it for a look at this etrailer five leaves slipper spring with the radius end for a 10,000 pound trailer axle.
