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.

Excellent product. The U-bolts fit the slipper springs nicely and were easy to install. I ended up not using the mounting plates as the plates welded to the existing axle matched the U-bolts. 927551

right part at a good price no problems since 806878
Reasonable price, quick delivery, exact replacement for my sagged, rusted together leaf springs on an old trailer I'm putting back on the road. They are made in China. I didn't see that in the description. Perhaps cou try of origin needs to be included. 794833
Product fit as it should and was easy to replace. Price was competitive. I'll come back to etrailer the next time, too. 778082
I really like these cheap 1.75" slipper springs. Unlike the even cheaper springs my jet ski trailer came with, these have a clamp to make sure they don't rotate or come apart in the front. These are a bargain for the price, but I would probably rate them in the 800 lbs range. 771158
They have everything you need for a boat trailer. Product comes in one or two days. Packaging is great. I recommend this Company to anyone that needs parts for their trailer. 763164

Great product for the price. The only draw back is you will have to weld spring tabs yourself. 747715

I used the advertised measurements to pick a replacement for my broken spring. The new springs were shipped soon after I ordered. When they arrived a few days later, I was happy that the new springs matched exactly the old ones. 722001
