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.

Video Transcript for Universal Group Trailer Suspension - Leaf Spring Suspension - SP-159275 Review

Today we're going to be taking a look at the 5 leaf slipper spring for 10,000 lbs trailer axles. It's made from a very strong and durable steel construction. It's going to flex to absorb road shock and provide a smooth ride, and it's really going to help reduce wear and tear on the trailer. The unit's going to ensure a level ride on bumpy and uneven surfaces. It's going to mount to the trailer frame with hangers, or a hanger kit. Those items are sold separately. It does come with the bushing over here at the eye; that's going to give us a inner diameter.

That opening right there is going to measure 3/4 of an inch in diameter. Again, when it comes to the number of leaves that the unit contains, we're looking at a 5 leaf design. The spring width, measuring from edge to edge, that's going to measure 2 1/2 inches wide. Spring capacity is 5000 lbs. Again, it's designed for 10,000 lbs.

trailer axles. A few length measurements to go over with you real quick. From the center of the eye to the end of the spring, that's going to give us a measurement of about 32 1/2 inches. Now, on this side right here you can see how the spring comes up, and then it levels out. If we measure that level area right there, pick a center spot, I'm going to measure from the center of the eye to this point right here. That length measurement ...

That's going to give us a measurement of right around 30 1/2 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 5 leaf slipper spring for 10,000 lbs. trailer axles. .

Replaced all four springs on a gooseneck equipment trailer. Trailer is used for moving heavy equipment from job to job. Went with the heaviest springs we could find and they have not let us down.

There is no real way to evaluate trailer springs until they have been tested under load. Even then to what could one compare them? Bottom line is the springs are made by Emco the industry standard spring maker. Etrailer ships high quality products at a decent price in a timely manner. If only they offered on site installation. Etrailer is THE place to get trailer parts!

    The slipper spring we offer that matches the important B measurement of your current setup would be the part # SP-159275. Only issue is that this is a 10k axle spring which would most likely be too much for your trailer.

  • Axle Placement and Suspension System for 20,000 lb Bumper Pull Trailer
    For your trailer, the axle placement will dictate the hanger placement as will whether you use double eye springs or slipper springs. When positioning a trailer axle or adding an additional axle, the key is to make sure that the axles are located in just the right position so that roughly 10 to 15 percent of the total trailer weight is placed on the tongue.
