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.

Includes bushings with 9/16" inner diameter.They look like really solid leaf springs they got hear at a decent time. But I can't use them cause I ordered them to smale. I needed 33 1/2 not 23 1/8 and wrong size bolt eye mine was 1/2 and width was not 2 inch but I was just going to get spacers 637113
The service was excellent and the springs were high quality. Exactly what I needed. I placed the order on Monday about 9 AM and they shipped them before noon. I received them at about 2 PM on Wednesday. Service could not have been any better. 564758
Fits /matches exactly what I needed from an older Tandem axle Terry 5th wheel. Hard to find, but etrailer had it no problem. 432465
This product was just what was needed to rejuvenate my old trailer. It rides (firmly) like new again. Easy to install with the trailer on its side. 558456
Michael - 08/26/2019The springs I replaced in the older 36ft fifth wheel camper we had arrived quickly and fit perfect at an excellent price. We camped the rest of the season and sold the camper to some people out of state and it pulled great with not a problem home for them as well. Will definitely be were I order my trailer parts from in the future. 539725
Theses springs were exact replacements for my 20 year old Mallard that had suffered a broken spring. Tremendous value, I bought all 4 springs with replacement greasable bolts and new bushings for less than a local rv shop wanted for just one spring. My feeling was that if one spring had let go what other springs had leaf cracks as well? With this price, replacing all 4 was a no-brainer. 413103
Alan W - 07/31/2018I haven't installed them yet because of the weather. When I do I will take pictures and add them to my review. 355333
Loran B - 03/18/2018These parts were for a 1977 Citation Travel trailer frame that someone had cut the springs off because the electric brake drums were to tight to roll and quite rusty so adjustment was not practical in the field.The springs and assembly pieces arrived promptly. The installation was completed in one hour. All parts fit exactly as they should. The goal is to make a storage trailer unit 8 X 18 feet. 293148

Parts are accurate! Service is top notch ! I will be ordering from again ! Thanks again 772593
Parts arrived yesterday and the new springs fit the trailer. I was not able to use the new U bolts because the threads on the bolts did not go far enough up the bolt to get them tight. So re-used the old U bolts and plan to return the new ones for credit. 771238

The replacement trailer spring set was out of stock but Michelle watched for it with care and kept me informed. She let me know when it came in, shipped it quickly and made sure I had all the nuts and bolts needed to replace my broken springs.

My utility trailer was listing to one side so much the fender was nearly touching the tire. Springs from etrailer solved the condition and once again it rides level even under heavy loads. Very pleased with the springs and with the service from etrailer. Highly recommend. 677172
