Bumpy pavement and rough boat ramps don’t have to shake your trailer apart. This 3-leaf double-eye spring flexes to take the hit so your load doesn’t have to. With a spring capacity of 1,250 lbs and a 2,500 lb axle rating, it smooths out the ride and keeps things level even when the road isn’t. The spring deflects about 1.43 inches at full load, helping your trailer track steady and resist bounce mile after mile.
Getting a good fit matters when you’re replacing worn springs. This one measures 25-1/8" from eye center to eye center (unloaded) and 1-3/4" wide, matching the common hanger spacing used on small and mid-size trailers. It drops right into your existing setup with hangers at about 25-3/4" spacing once loaded, restoring correct geometry so your shackles hang at the right angle.
A sagging spring can throw off alignment and wear out tires fast. This replacement is built from strong steel leaves (3 total, each 5/16" thick) for long service life under load. The included nylon bushings have a 9/16" inner diameter (11/16" without bushing) so standard suspension bolts slide right in. That combination resists wear, cuts down on squeaks, and keeps movement smooth through every cycle.
Whether you’re fabricating new mounts or swapping out old parts, this spring pairs cleanly with most double-eye hanger kits such as single-axle setups around 3-1/4" front / 1-1/4" rear hanger height. Replace both sides together to keep alignment true and ride height even. Once installed, it brings back proper support and lets your trailer handle its rated weight the way it should—solid, balanced, and dependable.

Perfect
Fast delivery, good price, quality pr oduct
Constructed well - beefy / strong
The springs look like good quality and the price was good. Delivery was amazingly fast.
Everything fit and arrived on time couldn’t ask for anything more great service
This order took a very long time.
The customer service and knowledge I get from Shawnee is what will keep me coming back. She’s a true asset to etrailer, and the complete line of products offered (in stock) is second to none! Thank you!
See earlier positive review. Great company and service.
Great service
Exactly as described on website, fast shipping will definitely use again
My order shipped quickly. Exact fit.
It took a while to figure out my exact spring I needed since they have such a huge selection!
But I called and a service representative was able to help me find the part number I needed.
Springs look like just what ordered.
Replaced the old springs on my boat trailer, the old original were just barely enough for the weight of the boat, I upgraded to these and the boat rides so much better.
This set of leaf springs was excellent choice for my 4’x8’ utility trailer, handles great.
Good product easy to install
Timely delivery and well packaged
Service was fast,appeared to be quality .im not happy with the springs after a year.my boat and trailer weighs 4200 lbs and the rated gvwr on the trailer frame is 5000lbs.i replaced my original single leaf springs with the 3 leaf from etrailer,4 at 1250lb each should have equalled my gvwr and exceeded my boat weight.they appeared fine at first but gradually over the year they started sagging and my shackles started hitting the frame.the springs visibly flattened and lengthened causing the problem.after calling etrailer they informed me there is no warranty and nothing they can do.i think their spring rating is a bit off.im going with slightly heavier springs next time
Love how fast your shipping was!! 2 days!! Amazing!! I really was impressed with how you updated who picked packed and shipped the order. That is really cool!
Very pleased with the Double-Eye Trailer Leaf Spring for my boat trailer. Service was great as well.
Thanks etrailer.

Great product but your shipping department needs to do a better job of packing the items. 2 springs were half way out!!
Outstanding products and staff my go to website before anyone else this particular project I ordered the wrong springs, I call etrailer expecting to eat the cost of my mistake and instead they sent me a return label for the return of my mistake and they immediately sent me the correct springs which I received in a couple days, this is why I continue to support etrailer because they support me.
Always very communicative customer service. Received/packed/shipped my order on a sunday(unheard of). It was delivered two days later. And that was the free standard shipping. I wish I had a need to do business with etrailer more frequently.
