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.

Today, we're going to be taking a look at the 5-leaf slipper spring for 10,000 pound trailer axles. This is made from a durable steel construction. It's going to flex, so it's going to absorb road shock and provide a smooth ride. It's also designed to reduce wear and tear on your trailer. It's going to ensure a level ride on bumpy and uneven surfaces. It's going to mount to the trailer frame with hangers or a hanger kit. Those items are sold separately.
If you are in need of those or interested in those, you can check out some options here at etrailer.com. You got the eye on this end here. It's got the bushing in there. On this end, you're going to have the slipper end. Now, this is a 5-leaf spring. It's going to have a spring capacity of 5,000 pounds and it is designed for 10,000 pound trailer axles.
Let's take a few measurements real quick. We are going to measure from the center of the eye to the end of the spring. That's going to give us a measurement of about 30 1/2 inches. From the center of the eye to the top of the bend, or the top of the curve, that's going to measure about 29 1/2 inches. The spring width, measuring just the thickness, edge to edge, is going to be 3 inches.
Then, the eye diameter is going to be 1 inch. Now, please keep in mind that in order to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs. That's going to do it for today's look at the 5-leaf slipper spring for 10,000 pound trailer axles.
