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.

Take a quick look at this 3-Leaf Double Eye Spring for your 4,000-pound trailer axle. Now this Double Eye Leaf Spring is going to act as part of your trailer suspension system by providing an attachment point for your 4,000-pound axle. This is made from sturdy steel, and it is designed to flex, to absorb road shock, and give you a smooth ride, reducing wear and tear on your trailer, and this is going to ensure a level ride on those bumpy and uneven surfaces. As you probably know, Double Eye Leaf Springs attach to hangers that are welded onto your trailer. One end of the spring will attach directly to the hanger with the suspension bolt, and the other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement.
If you have a tandem or a triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. And if you are in need of hangers, suspension bolts, or equalizers, you can find all of that here at etrailer.com. Now, in the eyes on each end are pre-installed nylon bushings. The eye diameter with the bushing is 9/16 of an inch, without the bushing it's 11/16 of an inch. And, again, this is a 1, 2, 3 leaf spring with the leaf thickness of 1/4 of an inch.
This spring by itself is rated at 2,000 pounds. That means if you install a pair, one on each side of your axle, you're covered for 4,000 pounds of trailer weight support, and to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs, and we do recommend installation by a professional. Now, looking at the length here measuring center of eye to center of eye, I hope you can see that there, we're sitting right at 25-1/4 inches on center. The spring width is 1-3/4 inches. So, if you're needing to replace worn-out springs on a light-to-medium-duty trailer, if your current suspension is sagging, noisy, or uneven, this is really going to be exactly what you need, especially if you are having suspension problems, and, again, we do recommend replacing them in pairs.
