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.

Double-eye leaf spring acts as part of a trailer's suspension system by providing an attachment point for a 5,300-lb axle. Spring flexes to resist shock and also ensures a smooth ride. Includes bushings with 9/16" inner diameter.I ordered 4 leaf springs and 4 U-bolt kits. (2 U-bolts per package) The products that I received were great ! The shipping box was damaged with holes in box and had been taped up by UPS. All the parts were loose in the box. It was MISSING 1 Leaf Spring, 2 U-Bolts and 8 U-bolt Nuts
My order use delivered in a timely manner and the springs are just what I needed, I up graded from 5 to 6 leaf springs due to a failure on the 5 leaf(not purchased from etrailer). I ordered four springs and the quality of the 6 leaf spring is good and they are performing well. Thank you.
Just like on the past ,parts arrived fast and fit like a glove. I had the trailer ready for the new parts. The truck deliver them and in 1hr i was pulling the trailer down the road .
