Shipping Weight: 14 lbs
Double-eye leaf spring acts as part of a trailer's suspension system by providing an attachment point for a 3,500-lb axle. Spring flexes to resist shock and also ensures a smooth ride. Includes bushings with 9/16" inner diameter.
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.

Today we're going to take a look at the 4-leaf double-eye spring for 3,500-pound trailer axles. This spring is designed to flex to absorb road shock and provide a nice smooth ride. It will help reduce wear and tear on your trailer. It helps you enjoy a level ride on bumpy and uneven surfaces and it mounts to your trailer frame with hangers or a hanger kit which we do sell separately on our website. Lots of times they are listed on this product page as a related product. It does include the nylon bushings in the eyes. A few specs on this.
The spring capacity is 1,750 pounds. It is designed to be used on axles with 3,500-pound rating. When you use this with one on the other side it will meet your 3,500-pound rating. This is for a quantity of one spring. It does have the four leafs as you can see, one, two, three, four.
I do want to give you a few measurements on this. We're going to do the spring length which is measured from the center of this busing to the center of this busing. You can see center-to-center is going to be right at 27 inches. We're going to do the width of it and the width is going to be right at 1-3/4 inches wide. The diameter of the eyes on each end is 9/16 of an inch. I just want to know we do want to recommend is that to ensure proper axle alignment and suspension performance, you do usually want to replace your leaf springs in pairs.
That should do it for the review on the 4-leaf double-eye spring for 3,500-pound trailer axles.

I 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 116826

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! 355950
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. 286207

Purchased double eye 27" 4 leaf spring as a replacement on double axel boat trailer. Product matched description, affordable. Great customer service. Arrived early. Would be nice if bottom leaf was extended width, to incorporate thru holes for U-Bolts to mount the springs to the axel. 293612

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. 41932

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. 281111

Thie leaf springs and bolts were delivered as ordered. My trailer is homemade, so getting everything to work was difficult through no fault of this product. The bolts are hard to tighten as they have sprockets at the head. Due to the way the trailer was built we had to improvise and go to local Autozone to buy 7-inch long u-bolts and plates. So, the only thing different that I would have done would have been to order the u-bolts from etrailer.com. 275884

I have been ordering parts from etrailer for my 5th wheel travel trailer for years. I goofed on this order and ordered the wrong leaf springs to replace a broken one. I immediately reordered the correct ones as soon as I discovered the mistake. I have always been satisfied with the products I have received from etrailer and know I will receive a quality product from them. I will repost when I receive the proper springs and install them. 275353

the trailer springs I ordered arrived much sooner than expected. they look great on my 40 year old home made trailer. If they last as long as the old original springs did I will be long dead but happy with your product. by the way a picture would not be pretty except for the new leaf springs. Thanks for the speedy shipping and a really great price!! 295985
I ordered multiple items from etrailer and the experience was perfect. The products arrived exactly as described with super fast shipping (standard option).

Received exactly what I ordered and fast too. I have ordered from etrailer before and spent some time searching for best price on these springs, just to make sure their prices were good. Save yourself some time and just use etrailer, they're the best. I would definitely recommend them. 57098

2nd time working with etrailer.com and both times were terrific. Don't pay for faster shipping because both times had the product to me within 2 days under the slowest option! Thanks I wish all online retailers were as efficient and great to work with as your team is! 127020
by: Bill H.11/22/2014
Great product at a great price!! Make sure to measure your shackle bolts....mine were 1/2" and these come with 9/16" nylon bushings. I had to place a new order for replacement 1/2" bushings. Not a big deal for me, but could have been a problem in a time crunch... 162232
