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.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this etrailer 3 Leaf Slipper Spring with the flat end, for a 2,900 pound trailer axle. Now this leaf spring will act as part of your trailer suspension system. Provides an attachment point for your trailer's axle. This one uses multiple leaves, which allow flexibility to absorb road shock. This will allow for a nice, smooth ride, reduces wear and tear on your trailer.

It'll even ensure a level ride on bumpy and uneven surfaces. This is a sturdy steel construction. You can see on the spring eye end, it has a nylon bushing on the eye end here. And it's pre-installed. Now to install this, it requires premounted hangers or an aftermarket hanger kit, which we sell separately on our website.

Those items are required for installation. Basically, the eye of the spring right here is what'll attach to a hanger mounted on your trailer frame. And then the slipper end down here is what'll slide into your hangar or equalizer. This is for a quantity of one leaf spring, has a number of three leaves. Spring capacity on this is 1,450 pounds.

It is designed to be used on axles that have a capacity of 2,900 pounds. Couple measurements on this are gonna be the overall length and then the width. So the length will be measured from the end of the flat end to the center of the spring eye. It's gonna be 30 inches. The width on this is 1 3/4 inches wide.

The eye diameter with the bushing in here is 9/16 of an inch. Now, one note I do wanna mention is to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs, and we do recommend installation be done by a professional. But that should do it for the review on the etrailer 3 Leaf Slipper Spring with the flat end, for a 2,900 pound trailer axle..

  • Upgrading Boat Trailer Suspension For Highlander 16' Trailer For 2,000LB Boat
    My first concern is determining the weight of your boat and trailer. It sounds like your trailer would have come with a 2,000lb axle as the Loadstar 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30670 has a maximum weight rating of 990lbs per tire. If your boat is over the 2,000lbs this would explain why your axle and springs are damaged. I can help you find the suspension components needed to increase your weight capacity but you should check with the trailer manufacturer to...
