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.

These were an upgrade for our GD Imagine travel trailer. We replaced 1750 springs and the trailer expert who just recently performed our 1 yr inspection, was impressed, and glad we invested in quality for the good of our trailer. I have the experts at etrailer to thank for helping me choose these items.
Had to replace a broken leaf spring on an older dump trailer. Having previously purchased products from etrailer I looked at their website first. Quickly found what I was looking for and made the purchase. There was also helpful information on their site to insure I ordered the correct springs.
Craig I - 06/09/2021I replaced my leaf springs, drums, brakes and added the Dexter E-Z Suspension kit to my Keystone Cougar Fifth Wheel trailer last year. This was my first time working with etrailer and I can’t say enough about how well it all went from the ordering to the install. Tammie P did a amazing job with knowing what parts would work best on my trailer. Tammie also gave me updates on my deliveries that I appreciated. I had a trip planned short after I received my parts. So having someone at their end checking on arrival dates helped. In the future I will definitely use etrailer for all my trailer needs. Thanks again for all the help! Great Team....
Total refit. Three axles, six springs, all pivot point bolts, bushings and link plates. Excellent pricing (the best I found). Super quick delivery, like three days. And free shipping on an order weighing close to fifty pounds? Best of all the company followed up a year later to see how it went. It went great, which why I'm writing this review. Quality, fitment, price, delivery, support. Five stars.
I ordered these to replace 4400# springs on our fifth wheel that are 10 years old. I was expecting the ride height to increase but it did not. They appear to be of acceptable quality but as with most products time will tell. We haven't used them yet but are planning a long trip next month.
Randy R - 08/28/2017After towing our rig 35,000 miles it was time to change the suspension. The old springs were flattened out and since I was doing the shackles and equalizers, for the cost, it was a no brainer to also do the springs. They fit perfectly and have performed flawlessly.
Changed out 4 broken springs for 4 new ones. They were a perfect fit and pretty easy to change. As far as customer service is concerned I wasn’t on the phone for more than 5 minutes and springs were on the way. I will definitely use etrailer again on my upcoming boat trailer project!!
The springs were installed without any problems. The wet-bolt bushings pressed into the spring eyes as they should, with no deformation such as what had been the case with the springs supplied with the OEM axle.
Excellent product, perfect fit and very easy to install. Attached is the pics of the new leaf spring, with my old and broken leaf springs. Thanks etrailer for getting my camper back on the road.
Great upgrade!! My 31ft Travel trailer rides MUCH better after replacing the stock springs with these!
Fit perfect. Installed the pair in about 1 hour and 20 minutes. That included cutting the old set off
Dick - 09/24/2021My 36 ft travel trailer was sagging 3-4" low on the drivers side. The problem was those 2 springs were flatter than the passenger side. It was noticeably lower. I jacked the frame up and installed the springs one at a time, didn't have any real problems. Installation for 4 springs took a couple hours, TT is setting level now. Great product.
replaced the springs on my travel trailer and rebuilt suspension linkage. Etrailer made it easy to order and received everything promptly.
I replaced all 4 springs under my 20' trailer and what a difference. Made it like new and at a very affordable price. The tables, charts, diagrams and descriptions given with all etrailer parts makes it so much easier to figure out what is needed and the correct parts. Had the order in my hands in less than 4 days from ordering. This is the fourth, or fifth, order I've placed with Etrailer and I will continue to order from them in the future, as the need arises. The products have been quality, price is unbeatable and shipping is quick. The tech support is also outstanding. Questions answered in a timely matter with a detailed answer and part references. Great Company to deal with. Thanks, Ken
It was a job to change it out but it has worke like new. Great job.
leaf springs fit exactly as listed, if I need parts or advise, etrailer.com is the first place I go, then after looking around I always go back and purchase from them!
Extremely quick service
The products I brought are exact and fit perfectly. The shipping was great, fast.
Was very happy to find this product at etrailer. Locally I was told that these springs were almost impossible to find because of the covid shutdown. I ordered this item and they arrived at my door step in a very short time. Swift responsible handling of my order. Without a doubt I will be back.
So happy with my purchase. Made a huge difference. I went one size up in weight capacity on my 28’ fifth wheel. Tows and sits a whole lot better and more sturdy. Paired with my new brakes I bought from etrailer It’s a whole new experience towing my trailer. 100% for the better. I recommend these. Especially for the price
I have been buying products from etrailer since 2009. I come back because the customer service in helping me find the right part or return a part is always, year after year, excellent! I needed 6 leaf springs for my toy hauler and couldn't find a part number. I called and Sandy helped me find a great replacement spring. I needed the springs quickly so we could go on a planned trip. Ordered them Tuesday, they arrived Thursday in perfect condition. I installed them and wow, the ride height restored, the camper sits square and wheels all straight. THANK YOU Sandy and etrailer. I will keep coming back. Michael
Assembled as expected and working fine with no problems. Installed on a dump trailer and loaded it to the max with no problems.
I've purchased several items from etrailer all have been top quality and received them all very quickly, the springs added give my trailer more support, the hubs I changed allowed my to add the wheels I wanted, the new fenders allowed for the larger tires and the lights made it brighter and improved safety Everything fit perfectly and at a great price I highly recommend them Thanks Shell
Shell H - 05/31/2017Replaced 4400 lb springs that were 13years old on 5th wheel did springs,shackles,bolts,equalizers,u-bolts,job went great, good parts so far. Do yourself a favor change everything at same time.
I received my new springs in a short time, they were exactly what ordered, I measured the old ones very careful with no load on them, wanted to get it right the first time. I have a 2014 25' Keystone 5th wheel, the springs were starting to sag and I was worried one might break, they were for 3,500# axles so I ordered springs for 5,000# axles, I installed them, they increased the height about 2 inches but they will settle a little after hitting a few bumps. One thing about this RV, you won't find anything in it that's an overkill.
