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.

Double-eye leaf spring acts as part of a trailer's suspension system by providing an attachment point for a 4,500-lb axle. Spring flexes to resist shock and also ensures a smooth ride. Includes bushings with 9/16" inner diameter.I ordered leaf springs and associated attachment hardware. I was quite amazed at how quickly the order was delivered even though the box weighed close to a hundred pounds. The order was complete and error free. The trailer was much improved by the installation and I look forward to using it. I have used etrailer.com in the past and it's my first internet stop for trailer parts.
Jim J - 10/23/2015I would have given these the highest rating because the product is excellent. The reason for just an average rating is solely because of the customer service or rather lack of customer service. I placed the order for this and 2 additional items to replace the entire suspension on a Passport 3350BH. All items were in stock when order was placed on 1/31/2022 with a delivery date of 02/03/2022. There was a snow storm on 02-03 which delayed the item to the following week which is understandable. However it continued to be delayed until the following week. After my first call I was told the storm had caused a delay. I asked why my order was in a gathering stage for days and then changed to back to order accepted, only response was the snow had slowed them down. After another week of no order, I sent 2 emails with just a standard response of blaming a snow storm 2 weeks prior. I asked several questions on my order which were never answered, I’d have to assume that they just didn’t care to answer or it’s a general email they send to everyone. Long story short the order came on 02/19 which is completely unexceptionable based on a 3 day original ship date. Hard to explain to a customer that a snow storm that we had as well pushed the ship date out 16 days on in stock items.
I been looking for springs of the load carrying capacity and length for my utility trailer. Great fit with no time spent modifying trailer for items to be used.
Old springs rusted out and were cracked. New mounts were welded up and springs installed. They work great. Probably a little to heavy for my specific application.
Alexander P - 03/28/2021I will use them for all my trailer needs in the future very help full through my trailer build.
Thanks
I actually ordered these for 65 Coronet Altered Wheelbase car for the front end using an A-100 straight axle.
The short 13" dimension from the center bolt to the spring eye makes this perfect for my application.
Mixing trailer with car spring attachments was a challenge but doable.
Enclosed are pictures of how it was mocked up with a relocation of 12" forward from stock.
I wasn't able to use the U bolts as they were a different dimension and diameter than the existing A-100 axle.
Using the front bolts with the Zerk fitting will be an added advantage being greasable.
You didn't have in stock what I needed you had something else that worked even better thank you so much
Easy purchase. I wanted full arc springs without flat areas. They’re perfect. A satisfying result.
Exactly what I wanted
Broke a spring on my bass boat the night before a tournament found these guys online ordered and the springs were here to the west coast in 4 days ! Great product, fast shipping and great customer service . They kept me up to date thru the whole process. Def would recommend.
Replaced old tired springs. Extra leaf raised trailer slightly. Worked great. Bolted right up.
Derek S - 04/26/2021Product came so fast! It was exactly what I expected and fits good!
best price quick delivery
Price was good, quality is good, customer service was helpful, delivery was fast. Just like every other time I've ordered from etrailer. The only reason I didn't give 5 stars is because the packaging could've been better. The springs were coming through the side of the box.
Put these on a boat trailer. Worked pe rfect.
The springs arrived quickly and are the proper fit.
The packing materials were insufficient, however. By the time the springs arrived they were bursting out of the box. Another day of handling and they would have been damaged. They were slightly abraded, but they are trailer springs, so it's no big deal.
Springs: Excellent
Packing: Poor
Upgraded my 1961 Shasta to 6 leaf after a broken 5 leaf happened. All new and good for another 60 years! Thanks!
Fast delivery…excellent product thank you guys do much!!
Parts worked out great.
Excellent service
great service
Works great. I mounted these on a 16' flat bed trailer. I use the trailer to haul my truck camper and ATV. Glad i didnt go any stiffer.
Order came in super fast and free shipping! Look forward to installing them this week on my trailer.
Would give a better review, but the description of the leaf spring pack did not include the thickness of the pack which made it very difficult to shop for a u-bolt kit.
Victoria B - 07/29/2020Prompt shipment and arrival. It was a few days before I installed one. The old ones which are probably original equipment ( it's a 1975 trailer) were a real pain to get off, but the new one was a perfect fit. I did the right side since it was broken, then took the trailer out and it worked fine. I am still getting the left side off, but I'm sure that the new one will be fine.
