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-269275 Review

Today we're going to be taking a look at the 6-leaf slipper spring for 12,000-pound trailer axles. This is made from a durable steel construction. It flexes to absorb road shock and provide a smoother ride, and it's going to reduce wear and tear on your trailer. Now, it's going to ensure a level ride on bumpy and uneven surfaces and mounts to the trailer frame with hangers or a hanger kit. Those items are sold separately; so, if you're interested or in need of those, you can check out your options here at etrailer.com. On this end we're going to have the eye. On this end we're going to have the slipper end.

The eye does include a bushing. It's already included, pre-installed, and ready to go. This is a 6-leaf spring. It's going to have a spring capacity of 6,000 pounds, so it is designed for 12,000-pound trailer axles. Taking a look at the dimensions real quick, we're going to go over a couple different length measurements, measuring from the center of the eye to the end of the spring and then the center of the eye to the top of the bend, or top of the curve, there. The center of the eye to the end of spring is going to be about 30 1/2 inches and then center of the eye to about this point right here is going to be about 29 1/2 inches.

The spring width, measuring from edge to edge, that gives us a width of 3 inches. Then the eye diameter is going to give us a diameter of 1 inch. Now, 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 6-leaf slipper spring for 12,000-pound trailer axles.

Ask the Experts about this Universal Group Trailer Leaf Spring Suspension

  • How Wide are Slipper Springs for a 12,000 Lb Axle
    I do have an option for you but you are going to have trouble finding a 2" wide slipper spring for a 12,000 lb axle as almost all, if not all 12,000 lb axles will use a 3" wide slipper spring, not 2" wide slipper spring. The best option we have for you is the 6-Leaf Slipper Spring w/ Radius End part # SP-269275 which is for 12,000 lb axles and is 30-1/2" long from the center of the eye hole to the end of the radius. We do not have a 2" wide slipper spring for 12,000 lb axles that is 29-1/2"...
