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 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.

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this 4-leaf slipper spring with open eye for your 4,300 pound trailer axle. Now, this slipper leaf spring is going to act as part of your trailer's suspension system by giving you an attachment point for a 4,300 pound axle. This is made from a sturdy steel construction, and it is designed to flex to absorb road shock and give you a smooth ride. It's gonna help reduce wear and tear on your trailer, and it's going to ensure a level ride on bumpy and uneven surfaces. Now, as you might know, slipper leaf springs attach to hangers that are welded onto your trailer.
The eye of the spring will attach to the front hanger with a suspension bolt, and then the 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. And the shape of the slipper end of a leaf spring may vary slightly due to differences among trailer manufacturers. Because of this, it is important to check your leaf spring slipper end before purchasing a replacement spring. 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. So leaf springs should always be replaced in pairs. And it is a good idea to have them replaced by a professional as well. Now, you probably already noticed, here in the eye is a pre-installed nylon bushing. The eye diameter with the bushing is 9/16 of an inch.
Without the bushing, it's going to be one inch. And again, this is a 4-leaf spring with a leaf thickness of 3/8 of an inch. And the spring itself has a capacity of 2,150 pounds. And again, combined with another spring that's also 2,150 pounds, that's going to give you that 4,300 pound trailer axle rating. Let me see if I can give you some measurements here, might be a little bit tricky.
But I'm going to give you the measurement from the center of the eye to the center of the open end here of the slipper spring. So lining that up as best as I can, looks like we are sitting right at 26 1/4 inches. I know that's kinda hard for you to see, but we do have other measurements listed with a diagram on this product page. So if there's other measurements that you're looking for, you can find them on this product page. And the overall width is 1 3/4 inches. But I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
