Leaf springs, as you probably know, make up an important part of your trailer's suspension. Their main purpose is to absorb road shock as you travel, as well as allow your axle(s) to move independently of the rest of the trailer.
To mount this leaf spring, you'll need hangers welded onto your trailer frame - which you probably already have in place - as well as shackle straps and a suspension bolt. It's a good idea to replace your existing straps and bolt while you're under there working on things because they tend to wear out quickly. One thing that could help keep them from wearing out too fast would be upgrading to galvanized or zinc-plated hardware. Doing so will boost the corrosion resistance and, therefore, the longevity of your trailer.
We also always recommend replacing both of your springs at the same time because it's not unusual for leaf springs to sag and elongate over time. If you replace just the one, there's a good chance that it won't match your existing spring on the opposite side of your trailer, and that can mess up your alignment.

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at this Three Leaf Double Eye Spring for your 3,500 pound trailer axles. Now this double eye leaf spring is going to act as part of your trailer suspension system by providing an attachment point for a 3,500 pound trailer axle. This is made from sturdy steel and it is designed to flex, so it can absorb road shock and give you a smooth ride, reducing wear and tear on your trailer. And it's going to ensure a level ride on bumpy and uneven surfaces.
Now, double eye leaves springs attached to hangers that are welded onto your trailer. One end of this spring will attach directly to the hangar with the suspension bolt, and the other end will attach to shackle straps that are suspended from a hangar. These straps are going to allow the spring to move and pivot so that it can better compensate for uneven pavement. So if you have a tandem or triple axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. So if you are in need of hangars, suspension bolts, or equalizers, you can find all that here at etrailer.com.
In the eyes on each end are pre-installed nylon bushings. The eye diameter with the bushing is nine 16ths of an inch, and without the bushing it's 11 16ths of an inch. And again, this is a three leaf spring with a leaf thickness of a quarter of an inch. This spring individually is rated at 1,750 pounds capacity. So that means if you install a pair, one on each side of your axle, you're gonna be covered for 3,500 pounds of trailer weight support.
So to ensure proper axle alignment and suspension performance, leaf springs should always be replacing pairs. And we do recommend insulation by a professional. Now, measuring springs, you are going to measure from center of eye to center of eye. As I hope you can see there, we're sitting right at 25 and a quarter inches. Obviously, when the spring is not loaded and when it's brand new, the width of the spring is one and three quarters inches.
So you're gonna need this spring if you're replacing worn out springs on a light to medium duty trailer. Maybe your current suspension on your trailer is sagging, it's noisy or uneven, or maybe you're restoring or building a small utility trailer, boat trailer or something similar. This is gonna be just what you need for that 3,500 pound axle. If you have any other questions about this spring or anything else that we carry, don't hesitate to reach out to us. We do wanna make sure that you're getting exactly what you want and need. Well, again, my name is Andy. Thank you for joining me.
