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 double-eye spring is suspended at the ends by hangers that attach to its eye or, in the case of tandem-axle or triple-axle systems, into hangers in the front and rear and an equalizer or equalizers in the center. To determine the type of hangers or hanger kit you need, you must know the specific type of leaf spring you have, as well as your axle diameter and capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications.

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at this 4-Leaf Double-Eye Spring for your 3,500-pound trailer axle. Now this double-eye leaf spring acts as part of your trailer suspension system by providing an attachment point for a 3,500-pound axle. This is made from sturdy steel and it's designed to flex to 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, 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, the other end will attach the shackle straps that are suspended from a hanger, and these straps are going to allow the spring to move and pivot so that it can better compensate for uneven pavement. Now if you have a tandem or a triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. But if you're in need of hangers, suspension bolts, or equalizers, you can find them all right here at etrailer.com. Now, in the eyes of each end here are pre-installed nylon bushings. The eye diameter with the bushing is 9/16 of an inch.
And again, this is a four-leaf spring, as you can see here. The spring individually has a capacity of 1,750 pounds, and then when you combine it with another spring of a similar capacity, that's where you're gonna get your 3,500-pound capacity for your 3,500-pound trailer axle. Let me go ahead and put a tape measure up and try to center, I'm trying to measure on center, the width between, or the length between the eyes there. So on center, as I hope you can see, we're sitting right at 24, I'm sorry, 25 1/4-inches long. Hopefully you can see that.
I know it's kind of an odd angle there. So again, 25 1/4 inches center to center. And the spring width is gonna be 1 3/4 inches. And we do have additional dimensions with the diagram listed on the lower part of this product page. So if there's any other information that you're looking for that I did not cover with you during our time together, don't hesitate to take a look at those additional measurements on this product page.
And of course, as you probably know, to ensure proper axle alignment and suspension performance, these springs should be always replaced in pairs, and typically we do recommend installation by a professional. If you have any other questions, don't hesitate to reach out to us. We do want to make sure that you're getting exactly what you want and need. Well, again, my name is Andy. Thank you for joining me.
