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 hooked 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.

Hi, everybody. Andy here with etrailer.com. Let's take a look at this six-leaf slipper spring with hook end for 8,000 pound trailers. Now this spring is made from sturdy steel (metal clanging) and this 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 for you, even on bumpy or uneven surfaces. This is designed to mount to your trailer frame with hangers or a hanger kit.
Those items are sold separately, but you can find them here at etrailer.com. In the eye is a pre-installed nylon bushing and the eye of the spring will attach to the hangar mounted on your trailer frame and then the slipper end is going to slide into your hangar or equalizer. And, again, this contains one, two, three, four, five, six leaves with a leaf thickness of 3/8 of an inch. This does have a spring capacity of 4,000 pounds and it's designed for 8,000-pound trailer axles. And then just to give you some measurements here, I'm gonna be holding up my tape measure here from the center of our eye, and we're gonna run it all the way to the end of our spring.
(measurer clicking) So let me see if I can line that up there for you. So measuring from the center of the eye to the end of the spring, as you can see, we are sitting right at 29 1/2 inches. The spring width, which you're probably not gonna be able to see from there, is two inches. (measurer clicks) And then the eye diameter with the bushing is 9/16 of an inch. Without the bushing, it's 11/16 of an inch.
Now to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs and we do recommend insulation by a professional. Well, that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
