Bumpy roads can make a trailer shake and rattle. This 3-leaf double-eye spring flexes to absorb road shock, giving a smoother ride and helping your trailer stay level even on uneven ground. Its design reduces wear and tear across your frame and suspension parts, keeping everything tracking straight mile after mile.
Strength matters when you’re hauling heavy. Each spring carries a 2,000-lb capacity, making a matched pair perfect for a 4,000-lb axle setup. The durable steel leaves work together to balance load forces and prevent sag, so the suspension stays consistent under weight.
Getting the right geometry keeps your suspension working smoothly. This spring measures 25-1/4"" from eye to eye and 1-3/4"" wide, with 9/16"" eye bushings already in place. That means it connects cleanly to standard hangers or equalizers using common suspension hardware.
The included nylon bushings keep metal parts from grinding together, which cuts down on noise and extends the life of your bolts and shackles. Smooth movement through the bushings helps maintain even flex in the spring pack for steady towing over time.
Each of the three leaves is built from sturdy steel to handle daily use and resist fatigue. At 3/8"" thick, they deliver a tough balance between flex and strength—ready to take road shocks head-on while keeping your trailer riding level and controlled.

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this 3-leaf double-eye spring for your 4,000-pound trailer axle. This double-eye leaf spring acts as part of your trailer suspension system by providing an attachment point for a 4,000-pound axle. It is made of a sturdy steel construction and it's designed to flex to absorb road shock and give you a smooth ride, reducing wear and tear on your trailer. And this is going to ensure a level ride on bumpy and uneven surfaces. Now, double-eye leaf springs attach to hangers that are welded onto your trailer.
On one end of the spring will attach, one end of the spring, rather, will attach directly to the hanger with the suspension bolt and the other end will attach to shackle straps that are suspended from a hanger. These straps are going to allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem or a triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. Now, if you do need hangers, suspension bolts or equalizers, you can find all that here at etrailer.com. In the eyes on each end are pre-installed nylon bushings and the eye diameter with the bushings is 9/16 of an inch, without the bushing, it's 11/16 of an inch.
Again, this is a three-leaf spring with a leaf thickness of a quarter of an inch, and it has a spring capacity of 2,000 pounds. So, when paired with another one on the other side, that's where you're going to get your 4,000-pound trailer axle capacity. Now, the length from center of spring eye to center of spring eye is gonna be 25 1/4 inches. The spring width is 1 3/4 inches, and additional dimensions with the diagram are available on this product page, if you're looking for other measurements of this spring. To ensure proper axle alignment and suspension performance, you probably know that leaf springs should always be replaced in pairs.
And if you do decide that this is going to be exactly what you need, that's great. We would love to hear back from you, though, after you get this installed and after it's been in use for a while, and you can share your experiences with us by either leaving a comment or a review on this product page, and with reviews you can also send us photos of this in action if you would like. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.

Fits perfectly. Super easy to install
Easy to say, but the product itself is high-quality steel, and what can I say about the staff who guided me through my order. They were perfect.
Looks of good quality leaf spring.
Bought (4) 7K leaf springs and 3 fit like a glove, however the 4th was slightly twisted and needed the help of ratchet straps to make the fit. I haven't driven it yet. Would have given a five star except for the one. Service deserved a 10 star rating.
Received Exactly what I ordered, Super Fast Shipping. Great Prices Thank You
Perfect fit. Take your time during installation, measure correctly and everything will fall into place.
Great customer service quick shipping t ime.
3 springs that are correct are fine. The 4 spring is the wrong spring, sent a 4 leaf instead of a 7 leaf, still waiting on the correct replacement.
Would be five stars if they came with bronze bushings
Shipping was pretty fast. Springs look good. Putting them on the trailer later today. Thank you!
Nice price. Quick delivery. Product was a perfect fit. I’m very happy and will return for my trailer parts.
Haven't installed as of yet but the customer service was excellent Fast shipping and good company follow up. Carter put all my questions and research at ease
I had called other suppliers, not answering phone or had no clue / answers to my questions
The paint/coating on the springs looks awful, hopefully the metallurgy is better. Also, the leafs are shorter than the OEM Dexter spring that it replaces.
The leaf spring showed up onto the campground a day earlier than expected! Great job getting us our part so we could enjoy our vacation!
Huge difference from 4 leaf to 5 leaf on my tandem 5200lb axles
These were the perfect replacement for the springs on my 10 year old Keystone Fuzion 414. They arrived in perfect condition and I was able to do the install myself. It took the entire day because I had never done it before but in the end, I'me very happy witht he outcome.
New springs eliminated the annoying trailer squeaking noise. Very Pleased five star rating
Perfect replacement for my stock Dexter Springs.
Also installed the Dexter EZ Flex Equilizer with Wet Bolt Kit.
Broken leaf spring): Ordered the leaf spring late Friday afternoon California time zone. (We travel full time). Most impressed, order was processed Friday night by E-Trailer, with two day delivery. Of coarse it was the weekend, part was picked up Monday morning in Missouri and I had it in my hands by 11:30am Tuesday. I could track the order easily with the link E-trailer provided. We were near Redcrest California, which is not a big town at all, about 50 miles south of Eureka CA.(no parts of this kind in the area). And the best part of all--the part fit perfectly! E-trailers website is very user friendly for getting the right part, the first time!!
The brass bushings should not have to be pounded in and then the bolt through the bushings because the bushings oblong them selves because the springs are not straight.
Springs look good and are very beefy. Should work well for the trailer application. The only problem I had was with the spring eyes. I removed the installed plastic bushings because I have wet bolt kits with brass bushings. When I pressed in the new brass bushings with a vice, 2 of bushing were distorted by the out of round diameter of the spring eye and the bolt would not go all the way through. I had to ream out the bushing using a 9/16" drill bit for the shackle bolt to go all the way through the spring. Apparently, the plastic bushings have enough "give" to avoid this issue. This was disappointing as I purchased these springs because they were made in the USA. I purchased a different pair of springs to use on this trailer, and I will keep these for spares or for a different trailer application. Probably not an issue if you stay with the plastic bushings.
I used these as an upgrade to my stock sagging springs. Going from 1750lb to these 2000lb springs lifted the trailer roughly 1 inch which was perfect as I'm often offroad
Haven’t had a chance to install them yet, I do believe they will work good. Replacing flattened old #3500 leafs with these for a single axel travel trailer.
