Rough pavement and uneven terrain can beat up a trailer’s suspension, but this 4-leaf double-eye spring keeps things steady. With a 3,500-lb axle capacity and 1,750-lb spring capacity, it flexes to take the edge off bumps and jolts. The spring’s multiple steel leaves work together to smooth out the ride, reducing bounce and wear on your trailer so it stays level and controlled mile after mile.

A sagging or stretched spring throws off alignment and stability. This spring restores your trailer’s proper ride height with its 27" length (eye-to-eye, unloaded) and 1-3/4" width. Each 3/8"-thick leaf provides balanced strength and flexibility. It’s built to handle the consistent load of a 3,500-lb axle setup, giving you dependable suspension geometry for secure towing.
Creaks, squeaks, and metal wear are common with old bushings. This spring comes ready with nylon bushings installed in each 9/16"-diameter eye. The nylon material cushions movement and cuts down on metal-to-metal contact, so the suspension moves freely without noise or premature wear.
The double-eye design fits right into standard hanger and shackle setups. One end mounts to a welded hanger on the frame, and the other connects to shackle straps or an equalizer. Whether you’re refreshing a worn suspension or replacing both sides for even support, this spring installs cleanly to restore proper function and tracking.

Fast shipping. Excellent service
ITEMS SHOWED UP OPENED SCRATCHED AND OUT OF BOX. VERY NORMAL FOR ETRAILER.
Etrailer went above and beyond when ups lost the shipment. They notified me of the issue and got another item shipped immediately. Very pleased!
Always use trailer and they never disappoint. Fast shipping.
Fast shipping and excellent communicati on
Amazing to be able to follow the shipment from order entry to every shipping location, the time at each location it was received, the time it left each location, until it was on the UPS truck and received at our home at the day promised.
Fast service
I ordered the wrong springs. I contacted “Paul” who is generating a return label. I’m being charged [XX] on a purchase of [XX] for the springs needless to say no more e trailer for me. A local shop had the right springs at [XX] each
I'm happy with the product and speed of shipping.
There was a clerical error on their side. I know this because I called this morning. Whoever placed the order misspelled my email. So I didn't receive a confirmation, invoice, or tracking number for a critical overnight order.
Instead of putting "Yahoo.com", they entered "Yaho.com" so I didn't receive any follow up info.
It will not stop me from making future orders.
Great product. My fault by ordering too short. Paul B. Worked with me and had a shorter and heavier version in the mail.
Trailer sticker for GVW is unreadable so I was in SWAG mode on leaf weight. Product looks great though, just mot enough clearance between tire and fender.
PAUl B is very helpful. After the springs, on to the full brake system replacement.
Thank you very much my fish house is ready for ice. Happy holidays to all of you and thanks again.
product was as advertised
So far so good. More after I have used for awhile.
Great item, just as described. Perfect fit for my application.
Good leaf spring for a reasonable price
Arrived quickly and fit perfectly. Can't get any better than that.
Integral part for suspension for my 3.5k trailer.
Perfect fit, easy assembly, fast shippi ng
Fit perfect
Received yesterday and it looks good and sturdy.
Springs were great, customer service in finding the right length was outstanding as the trailer manufacturer (Keystone) did not provide adequate documentation and could not verify the model using the VIN. Shipping was free and amazingly fast for such a heavy item.
Fits like a glove just what I need
I ordered a leaf spring for my trailer and everything worked out exactly as I hoped. The website was easy to navigate and pick the correct part for the trailer, the turn around on the order to shipping was fast and the part was delivered on time and in great condition. I definitely will be ordering more parts for my trailers from this site in the future.
Quick shipping - and product looks grea t!!
Worked great. Perfect replacement for the springs on my vintage trailer!
