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.

Video Transcript for Review of etrailer Trailer Leaf Spring Suspension - 7 Leaf Slipper Spring Hook End 8K Axle - e37SR

Hi, everybody. Andy here with etrailer.com. And today we're gonna take a look at this seven leaf slipper spring with hooked end for 8,000 pound trailer axles. This slipper leaf spring ax is part of your trailer suspension system by providing an attachment point for an 8,000 pound axle. It is made from sturdy steel construction and it is designed to flex, to absorb road shock and provide a smooth ride, reducing wear and tear on your trailer. And it's going to ensure a level ride on bumpy and uneven surfaces.

Slipper leaf springs attach to hangers that are welded onto your trailer. The eye of this spring will attach to the front hanger with the suspension bolt and the hooked slipper end of the spring will slide into the rear hanger. Now, 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. So because of this it is important to check your leaf spring slipper end before purchasing a replacement spring.

If you're in need of hangers, suspension, bolts or equalizers, you can find them right here at etrailer.com. In the eye is a pre-installed nylon bushing, as you can see here, and the eye diameter with this bushing is gonna be nine 16ths of an inch. If you take this bushing out the eye diameter will be one in five 16ths inches. Again, this is a seven leaf spring as you can see right here. And the leaf thickness is three eighths of an inch.

This has a spring capacity of 4,000 pounds. And again, it is designed for 8,000 pound trailer axles. Now measuring the length here from the center of the eye to the end of this spring, we are sitting right at 26 and five eighths inches long. In the spring width, we are right at two inches. And I do wanna mention that additional dimensions with the diagram are available on this product page.

So if you we're in need of those measurements you can check those out on this product page. To ensure proper axle alignment and suspension performance, leaf spring should always be replaced in pairs. And we do recommend installation by a professional. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

See what our Experts say about this etrailer Trailer Leaf Springs

  • Will 7-Leaf Slipper Spring Work If It's 1/4" Shorter Than Current Leaf Spring
    It isn't uncommon for leaf springs to expand a little over time as they start to wear down and flatten out. Since your leaf spring measures 26-7/8" that's only 1/4" more than the 7-Leaf Slipper Spring w/ Hook End for 8,000-lb Trailer Axles # e37SR which is perfectly normal so you'll be good to go in those regards. As a rule, whatever happens to one side of the axle needs to happen to the other side of the axle to keep everything operating and wearing smoothly so you definitely want to...
