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.

They fit my trailer and seem to be holding up well. 674809
We are so pleased with our interaction with etrailer. We were dry camping in the desert and had no good access to the website. Lori got us the right parts we needed and even gave me her direct line number in case we needed it The only bad thing was one of the boxes was damaged and some of the nuts we needed were missing but we were able to use the old ones. We had to replace leaf springs. This is not etrailer's fault though. We would use them again in a second. Very friendly and helpful. Thanks for getting us back on the road. 595996
First off I was in need of parts ASAP so I searched the web and found this site, that being said I made a purchase of greasable bolts, spring plates and new upgraded springs, 3 days later I received all Of my parts and installed without any problems. The new springs gave my trailer a much needed lift of about 4-5 inches and improved the ride by 100%. All in all this was a great experience and very good products. I will continue to purchase from them and highly recommend them to everyone who has a trailer! 424813
Jayco, the manufacturer of our 4 year old RV, grossly undersized the axle leaf springs when it was built. The GVWR rating tag on the RV said it was good for 9750# but Jayco only put springs rated for a total of 8000#. Consequently the springs failed after 4 years and less than 5000 miles use. (See picture of old/new springs). I upsized the new springs to a total of 12000# and once again the RV sits as high, maybe 1/2 inch higher than when it was new. Etrailer.com site was easy and helpful to use. The springs and u-bolts arrived in just a few days and were well packaged. Thanks to etrailer we are safely on the road again. 540002
It went together fine, lifted the trailer bed a good 5-6 inches off the tires and looks strong; time will tell. First picture is BEFORE, 2nd pic is AFTER 413051

Very good 849732
I recently placed an order for new trailer springs and some brake parts. Daniellee made sure I had ALL the correct pieces put the new springs on. The box was damaged somewhere along the way in shipping and someone tried in vain to patch it up with tape. There was probaby a whole roll of packing tape on the end. Needless to say some parts fell out and were lost. I called them up immeditially and explained the issue. Bridget responded and had the missing parts in the mail the very next morning. AWESOME company and AWESOME customer service. Will continue to do business with them for any of my trailer needs. 849264
Got it fast and works great. 792155
I wanted to put larger tires on my 5th wheel trailer. It had 225/75/15 load range D from the factory. I tried first by ordering HWT- Series S5 16x61/2-6 part # AM 22658 HWT B wheels, and 4 Sailun S637 -ST 235/80/80R /16 load range 129 tires. Found I didn’t have enough room for them to fit. So I ordered 4 new springs Item SP - 053275 six leaf springs and a larger equalizer item TREQ-310. All the parts except the tires we’re purchased from Etrailer.com. My trailer already had the axles flipped and the longest hangers installed. So getting the new springs and equalizers did the job I now have the space to use tires that will allow me to actually put a near full fresh water tank for dry camping. I am very careful about what I put in my trailer and weigh it frequently and use a safety factor in loading! Etrailer was very helpful in suggesting items, and were fast in shipping . I would use them again! 772930
