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 hooked 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 7-Leaf Slipper Spring with Hook End for your 8,000-pound Trailer Axle. Now, this slipper leaf spring acts as part of your trailer's suspension system by providing an attachment point for your 8,000-pound trailer axle. It is made of sturdy steel, and it's designed to flex and to absorb road shock, and give you a smooth ride. That'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 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 hooked slipper end of the spring will slide into the rear hanger. Now, if you have a tandem or a triple-axle trailer, the slipper end will slide into the equalizer that connects to 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. Now, if you're also in need of hangers, suspension bolts, or equalizers, you can find all that here at etrailer.com. In the eye is a pre-installed nylon bushing.
The eye diameter with the bushing is 9/16 of an inch, and without the bushing, it's one 5/16 of an inch. Again, this is a 7-leaf spring with a leaf thickness of 3/8 of an inch, and it has a spring capacity by itself of 4,000 pounds, but then when it's paired with another one on the opposite side, that's where you're gonna get your 8,000-pound trailer axle capacity. And then the length from the center of the spring eye to the end of the spring right here right before the hook ends is gonna be right at 26 5/8 inches. The width of the spring is two inches. Now, additional dimensions with the diagram are available on this product page if there are some different measurements that you're looking for that I didn't provide for you today.
And to ensure proper alignment and suspension performance, I'm sure you know this, it is important that leaf springs should be always replaced in pairs, so if you pick one or more of these up and you get it installed, we would love to hear back from you regarding your experience with this spring, or with the set of springs that you pick up, and you can share your experience with us by either dropping a comment or leaving a review on this product page letting us know how everything worked out for you. We would love to hear back from you. Well, that's gonna wrap up our look today. I do hope that our brief time together was helpful for you. Again, my name is Andy, thank you for joining me.
