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.

These springs have made all the difference for me with my trailer. I have a 2013 Keystone Ultralite Bullet and once I upgraded to these springs any issues that I had with my brakes along with my slide have all but disappeared. I am so grateful to the etrailer staff for all their support in helping me get the best springs for me.
I purchased 2 of these because one of the leaf springs broke on one side of my trailer. It was a perfect fit.
Awesome, broke both rear leaf springs (mono leaf ) when we pulled in to the campground. I searched for something to upgrade from the weak mono leafs . I have the wide stance axles on my camper so I needed 30 inch springs . E-Trailer was the only place that had the upgrade that could hold the weight . I ordered the springs at 4:11 pm and they shipped that same afternoon. And no not just a label created they were actually picked up by ups that same day . Once they arrived and were installed I couldn’t believe the difference they made . Now the camper rides at the correct height. E-Trailer is definitely my go to place for parts .
Great product very friendly and prompt staff. The delivery system of UPS was bad took 4 days longer than expected. They had no problem getting on the phone with UPS and resolving the issue, highly recommend etrailer!!
Quick free delivery. Part as described.
