Bumpy highways and uneven ground can make towing rough on your trailer. This 4-leaf slipper spring flexes as you travel, soaking up road shock to keep the ride smooth and steady. Each of its four 3/8"" thick steel leaves works together to cushion vibration and help your trailer track level, reducing wear on the frame and gear inside. With a spring capacity of 2,350 lbs and an axle capacity of 4,700 lbs, it’s built to handle the load without giving up comfort.
A solid suspension setup only works as long as the parts hold up. This slipper spring is made from sturdy steel with a powder-coated finish that stands up to rust and moisture. It’s a dependable choice for trailers that see all kinds of conditions, including marine use where corrosion resistance really matters.
Getting the right fit makes all the difference when replacing suspension parts. This spring measures 26-1/4"" from the center of the spring eye to the center of the open end, built to fit standard hangers and equalizers with a 1-3/4"" wide leaf stack. The front eye comes pre-fitted with a nylon bushing sized for a 9/16"" bolt, so it’s ready to install using your existing hanger setup or an aftermarket hanger kit (sold separately).
When old springs sag or stretch, your trailer can lean or bounce unevenly. This slipper spring restores balance by providing a precise attachment point for the axle so it stays in line with the frame. The open-eye design allows the rear end to slide smoothly into the hanger or equalizer, giving steady movement under load for consistent handling across single, tandem, or triple-axle builds.

Hi everybody, Andy here with etrailer.com. Let's take a quick look at this four leaf spring with open eye for your 4,700 pound trailer axle. Now this slipper leaf spring acts as part of your trailer suspension system by providing an attachment point for your 4,700 pound trailer axle. This is made of sturdy steel construction with a powder coat finish to help resist rust and corrosion. This is designed to flex, to absorb road shock, and provide 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 probably know, slipper leaf springs attached to hangers that are welded onto your trailer. The eye of the spring will attach to the front hanger with the suspension bolt, and the 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, and the shape of the slipper end of a leaf spring may vary due to differences among trailer manufacturers. Because of this, it is important to check your leaf springs slipper end before purchasing a replacement spring. Now, 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. Leaf spring should always be replaced in pears, and we do recommend installation by a professional. Now, in the eye is a pre-installed nylon bushing. The eye diameter with the bushing is nine-sixteenths of an inch. Without the bushing, it's one inch.
And again, this is a four leaf spring, and the leaf thickness is three eighths of an inch. And individually, this has a capacity of 2,350 pounds. Of course, when you combine this spring with the other spring of the same capacity on the other side of your trailer, that's where you get your 4,700 pound trailer axle capacity. Now let me go ahead and measure this spring for you. I wanna measure the length first, and so slipper springs can be a little bit tricky to measure.
So what I'm doing is I'm measuring from the center of the eye to right about, near the center of the hook there of the spring, so, of the slipper end rather. So we're sitting right at about 26 and a quarter inches long. And the width of the spring is one and three quarters inches. I do want to point out that additional dimensions with the diagram are available on this product page. If there's any other information that you're looking for, measurements or instructions on how to measure springs. But if you happen to have any other questions about this or any of the other parts that we carry here at etrailer.com, don't hesitate to reach out to us, 'cause we do wanna make sure that you're getting exactly what you want and need. Well, I think it's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
