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.
Double-eye leaf springs attach to hangers that are welded onto your trailer. One end of this spring will attach directly to the hanger with a suspension bolt. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs.
To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your trailer. You should, however, replace your shackle straps because they are usually the first component to wear out. You may choose to replace old suspension bolts as well. It is 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.

Waited until the last minute to pick up an extra leaf spring for my trip to Alaska. Fast shipping got it here in plenty of time. Thanks!
Having never replaced a leaf spring before I decided to go ahead and give it a shot on my own. I reviewed the information on etrailer.com and found the replacement parts without a problem. Once they arrived I removed the old worn leaf springs and replaced them without much trouble at all. Back to safe trailering. Thanks etrailer for the help.
I ordered the wrong leaf spring by mistake. Etrailer exchanged them for me. I had to pay shipping. Guess I should have ordered more carefully.
etrailer is a fantastic company and responds to customer service questions within a day, in my experience with them. They worked hard to advance an arrival of this item I needed in a hurry, for which I am very grateful. We would have missed a camping trip without their help. Kudos to George and Rachal at etrailer! You can count on them. Oh, and the springs were an exact fit in every way.
I completed construction of a mobile bandsaw mill and found the springs on the mobile home axle I used were much to strong. I believe they were rated for 6,000 pounds and did not flex with the light load of the bandsaw mill. The SP-210275 were a perfect fit for my need. Shipping was very quick and other than needing to purchase longer "U" bolts, I was able to simply remove the old springs and bolt the new springs right into place. Very satisfied with this purchase and installation.
fixed my issues. trailer doesn't bottom out on big pot holes now and it rides smoother.
Ben - 06/10/2022I purchased the 3000# axle springs and all mounting hardware to replace the old ones on my 1963 travel trailer. My trailer no longer leans to the left and goes down the road better than new. I should have done it many year ago. I received my package on time and installation was easy and fit perfect. Thanks Bridget
Easy to install!!! Working well in the trailer!!!
2500 miles in and the trailer is still smooth as the day I installed the new springs.
I discovered that I needed to fit the holes in the bottom of my axle onto the studs on the springs before tightening the hardware fastening the springs to the rear shackles and front hangers.
Parts fit as advertised, very satisfied with purchase. I new nothing about replacing a trailer axle info on web site and support provided were excellent.
Definitely would recommend etrailer
With the outstanding help from Tommy at etrailer.com, I was able to purchase the right axle, hubs, spring and tires the first time. Everything arrived in good condition, went together like a dream. I was impressed with the quality of product and service.
replaced the parts and installed on trailer fit was great
The springs fit great however new hardware would have been nice.
Hello,I would like to say I am very satisfied with etrailer.com shipping was fast, price was great,now I'm ready to go catch them bass .
Received earlier than expected, parts fit wonderfully. Quick and simple install.
Good quality product, fast delivery.
Easy installation dose what I need it to do.
The springs arrived quickly and they were an exact fit. Installed in about 1 1/2 hrs. Thank you very much
Well, I just got the parts, so can't say anything reliable on chinese made parts.
The price was(is) Great! a boat load cheaper then the local store....humm.
springs fit perfectly, however, the springs I wanted are no longer being offered, could of had springs made but I went with the less$isMore theory. (more in my pocket)
The "white" nylon bushings I ordered would not fit into the equalizers, but the grey colored ones I had did fit perfectly, just a-hair difference in outer diameter.
The bolts fit perfectly as well.
It is always 10 times easier dealing with eTrailer then the local store, So I know eTrailer has put a lot of time into making it easy for their customers, Thanks!
Very Fast shipping, all at a price I can afford!
The price was right and shipping was fast, and the video on measuring made it easy to be sure I was ordering the right part for my trailer. What's not to like? The only mistake I made was in not ordering all the hardware (U-Bolt kit, shackle bolts, and shackle straps) all at the same time. Although the videos say these parts can be reused, mine were rusty enough that they were really hard to get apart and then back together, even though they were only a year old.
Great service. I know that I needed to do something to my trailer but I had no idea where or how to get the right parts Everything was too rusty to find any part numbers. I sent them a few pictures and gave them the measurement that they asked for and in about 30 mins I had a complete parts list of what I needed. When I got the parts everything was correct and fit great. Will defiantly be ordering from them again. Preston, and Jessica B were very helpful....
Corey - 03/01/2019Thank you etrailer!
The shipment arrived sooner than expected, the leaf springs along with a hanger kit arrived in a heavy duty box with very good packaging. As for the leaf springs they're heavy duty thicker gauge compared to the ones currently on my utility trailer. With beefing up my suspension I'll be able to raise my box and carry a heavier load with my current axle.
All Parts arrived as ordered and their quality and type is as expected, thank you.
However, I would suggest better packaging when shipping leaf springs. The loose nature of the packaging seems to have caused the leaf springs to puncture the box causing a 2 day delay in shipping and the potential loss of my other items.
Mark - 08/25/2019The leaf springs arrived and look excellent. The shipping and customer service has been top notch.
One note, the retention bolt on the bottom of each spring is slightly larger that the bolts were on the old springs (1964 Shasta travel trailer). Accordingly, I'll have to drill out the bolt hole on the axel leaf spring seat to accommodate the new bolt size. Otherwise, smooth sailing.
