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.

Hello, everybody, this is Jeff at etrailer.com. Today we're going to take a look at the Dexter 25 1/4 inch long 4-Leaf Double Eye Spring for 4,400 pound trailer axles. Now this leaf spring will act as part of your trailer suspension system, provides the attachment point for your trailer's axle, and there's multiple leaves to allow flexibility to absorb road shock. This one has four leaves, allows for a nice smooth ride, reduces wear and tear on your trailer. That'll ensure a nice level ride on bumpy and uneven surfaces. Now the length of this is measured from center of one eye to the center of the other when it's unloaded like it is now.
So if we get our tape measure and go center to center, 25 1/4 inches length. (tape measure rattling) Width on the spring is 1 3/4 inches. This is a sturdy steel construction. If you notice in the eyes, they do have the nylon bushings, which are included, and the eye diameter with that bushing installed is 9/16 of an inch. Now premounted hangers are the aftermarket hangar kit, which is required for installation.
Those items we do sell separate on our website. And this spring will attach to the hanger mounted on your trailer frame at one end, and then the other end connects to shackle straps suspended from your hanger or equalizer. This is for a quantity of one leaf spring. The spring capacity is 2,200 pounds, so when this is used with one on the other side of the axle, it'll meet the 4,400 pound axle capacity. Now there are additional dimensions of this spring that's listed on the product page if you do need them.
But that should do it for a look at this Dexter 25 1/4 inch long 4-Leaf Double Eye Spring for 4,400 pound trailer axles.
