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 flat 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.

Today we're going to be taking a look at the three leaf slipper spring for 1500 pound trailer axles. The spring's made from a very strong and durable steel construction. It's going to flex appropriately to absorb road shock and provide a nice smooth ride. Ultimately, this is going to help reduce wear and tear on your trailer. It's going to help ensure a level ride on bumpy and uneven surfaces. These are designed to mount to the trailer frame with hangers or a hanger kit. Those items are sold separately.
If you are in need of a hanger or a hanger kit, you can find those items here at etrailer.com. Over here at the eye, it does include a nylon bushing. The eye diameter's going to measure 9/16 of an inch. You can see this as a three leaf spring, so it's going to contain three leaves. The spring width form edge to edge is 1 and 3/4 of an inch. Eye diameter's 9/16.
When it comes to the spring capacity, it's going to have a capacity itself of 750 pounds, so it's designed for a 1500 pound axle, that would be the axle capacity if you're using two of these. I want to give you the spring length measurement. From the center of the eye to the very end of the spring. That's going to give us a measurement of about 24 and 5/8 of an inch. If we measure from the center of the spring to the top of the bend here on this end, that's going to give us a measurement of around 23 inches. Please keep in mind that in order to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs. That's going to do it for today's look at the three leaf slipper spring for 1500 pound trailer axles..

Replaced rusty springs on a 14' skiff trailer. Fit perfect, DIY for cheap in the driveway, it would've been easier with an impact wrench. Take their advice, etrailer is the best for a reason, get ALL NEW HARDWARE TOO!! I broke several fasteners removing them, if the springs are bad, so is the hardware. I have done three hitches and a set of leaf springs now with these folks. Their install videos and expert advice made it a breeze to save probably a couple thousand in labor at a shop. 458343
