Rough pavement and uneven ground can make a trailer bounce hard. This 3-leaf double-eye spring flexes just enough to soak up road shock and keep things steady. Each of the three leaves works together to cushion impact so the trailer rides smoother and the frame, cargo, and suspension take less abuse.
Strength matters when your trailer is loaded down. This spring is built from sturdy 1-3/4"" wide steel with a total axle capacity of 4,000 lbs and a spring capacity of 2,000 lbs. The 1/4"" thick leaves hold their shape under weight while still allowing flex where it’s needed. It gives solid support mile after mile without sagging out early.
Moisture and salt can take a toll on suspension parts. The powder-coated finish on this spring resists rust, making it ideal for marine environments or long stretches in wet conditions. The coating seals the steel against corrosion so the spring keeps working smoothly even after exposure to water or road grime.
The double-eye design makes installation straightforward—one end mounts to a hanger on the frame and the other connects to shackle straps or an equalizer. It comes with durable nylon bushings already in place, each with a 9/16"" inner diameter for standard suspension bolts. Everything lines up cleanly so you can bolt it in and restore proper suspension movement without extra prep work.

Take a quick look at this 3-Leaf Double Eye Spring for your 4,000-pound trailer axle. Now this Double Eye Leaf Spring is going to act as part of your trailer suspension system by providing an attachment point for your 4,000-pound axle. This is made from sturdy steel, and it is 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 those bumpy and uneven surfaces. As you probably know, Double Eye Leaf Springs attach to hangers that are welded onto your trailer. One end of the spring 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 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. And if you are in need of hangers, suspension bolts, or equalizers, you can find all of that here at etrailer.com. Now, in the eyes on each end are pre-installed nylon bushings. The eye diameter with the bushing is 9/16 of an inch, without the bushing it's 11/16 of an inch. And, again, this is a 1, 2, 3 leaf spring with the leaf thickness of 1/4 of an inch.
This spring by itself is rated at 2,000 pounds. That means if you install a pair, one on each side of your axle, you're covered for 4,000 pounds of trailer weight support, and to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs, and we do recommend installation by a professional. Now, looking at the length here measuring center of eye to center of eye, I hope you can see that there, we're sitting right at 25-1/4 inches on center. The spring width is 1-3/4 inches. So, if you're needing to replace worn-out springs on a light-to-medium-duty trailer, if your current suspension is sagging, noisy, or uneven, this is really going to be exactly what you need, especially if you are having suspension problems, and, again, we do recommend replacing them in pairs.
If you have any other additional questions, whether it's on this spring or anything else that we carry here at etrailer.com, don't hesitate to reach out to us. We do wanna make sure that you're getting exactly what you want and need. Well, again, my name is Andy. Thank you for joining me.

Ratings & Reviews
I installed one leaf spring shortly after I received the three I ordered. Quality appears to be excellent. The fit was perfect! Chris, who helped me with the order was both professional and personable. He made sure I got what I needed and follow-up was excellent. Have dealt with etrailer.com previously and was pleased then and am now! They are competitive in their pricing and quality is always great.
WOW, what quality! I recommend etrailer for your orders.
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.
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
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
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.
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.
