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 gonna take a look at the 7 leaf slipper spring for the 15,000 pound trailer axles. Now, this spring is a strong, durable steel construction. It is designed to flex to absorb road shock, provide a nice smooth ride. Also reduces wear and tear on your trailer. Helps to enjoy a nice, level ride on bumpy and uneven surfaces, and it does mount to your trailer frame with hangers, or a hanger kit, which we do sell separately on our website. Lots of times, it is included as a related product on this product page. If you notice on the eye portion right here, it does include the rubber bushing.
A few specs on this: the spring capacity itself is 7,500 pounds, and when this is paired with 1 on the other side of the axle, it'll reach your axle capacity of 15,000 pounds. If you notice the number of leafs on this is 7. 1, 2, 3, 4, 5, 6, 7. I do want to give you some measurements. We're gonna start with the spring length.
The spring length is from the center of the eye to the end of the spring itself. So if we go from the center to the end, it's 30 and a half inches. The width on the spring is right at 3 inches wide. The eye diameter in the eye right here, the inside diameter is 1 inch. This part is for a quantity of 1 spring. Now, 1 last note on this, is to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.
That should do it for the review on the 7 leaf slipper spring for 15,000 pound trailer axles.
