Double-Eye Spring

Part NumberABCD

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.

Great product! It fit properly and gives the trailer a new life. The trailer sits level and tracks well behind its tow vehicle.

Great product! I improved the trailers capacity and safety for a fraction of the cost of a new trailer.

Honest opinion. This was the easiest order for parts I have experienced. Parts were delivered quickly,and plenty of follow up by etrailer to ensure: order was as described, and delivered on time. My only place to order trailer parts.


I purchased a number of products from etrailer and I am very pleased with them all. The shipper lost my axle. When I contacted etrailer customer service, they handled my problem quickly and I had a replacement axle in a couple days. Well done!

The products were all of high quality and the assemble was much easier as a result. I have attached a few pictures of the build for those interested.

Thanks etrailer for your great products and service!!

The trailer has performed better than my expectations. The products I purchased are all performing perfectly. When I build my next trailer, I will get all my assemble products from

fit nicely on my ranger RT188 bass boat single axle trailer.


Right now it's too cold to work on the trailer, January in NY. This is my second order with etrailer and ther were no problems I got what I ordered on time and have no qualms recommending them.
Thank You


Once again, etrailer was fantastic. Their website had all the information I needed. Before last week I had no idea what a leaf spring system was, all I knew was that whatever that thing was on the bottom of my camper was snapped in two and I needed to fix it. Did some research on, it walked me through how to take the measurements and what I needed to look for. I took the measurements and found the product that fit my camper. As I always do, I shopped around, and once again, etrailers price was the best by far. I placed the order on a Friday morning and received a very nice email that afternoon from etrailer thanking me for being a repeat customer and notifying me they had expedited the shipping of my products and they left the warehouse that same day. Showed up on my porch the following Wednesday. Amazing customer service!

I ordered the leaf springs, ubolts, shackles and shackle bots needed to replace the springs on both sides of my camper. When I opened the box, everything I ordered was in there and looking great. They shipped exactly what I needed, when I needed it at a price that couldn't be matched anywhere. Everything looks great, haven't had a chance to get them on the road yet, but I'm sure it will be top notch when I do.

Thanks again etrailer!


Delivery was very prompt sooner than expected. The information your site provided was spot on. I was able to find a more durable tire for a trailer we are pushing the tire limits. And increase the spring rating by only 500lb fisrt time I've seen off the shelf springs offered in such finite sizes. Though we load within the limits of our trailers this particular unit is at the top of the load range. The slightly heavier parts give me confidents we'll get where we want to go. Thanks we'll be calling again.


Provided the perfect replacement for an older Trailex open car trailer. Springs were exactly as described. Just make sure you purchase the right spring for the trailer capacity.

These guys were able to get me the leafsprings overnight so I could get to the track on time. Really appreciated the customer service!


Thanks to, I was able to find out that this is the right spring for my trailer. Where before, my trailer was dangerously bouncy, now it rides as smooth as it should. Also thanks to etrailer's video, I knew exactly how to install it. It was very straightforward, and although it took some elbow grease, it wasn't too difficult in the end. Spring works perfectly, just what I needed.


Great product, super price, and really fast shipping makes etrailer top on my list for any trailer parts I may need in the future. I purchased leaf springs for a trailer I'm building and they are a perfect fit.
Thanks etrailer


Great service, a special thanks to Jackie Childess for checking into so many questions I had to make sure I received the right product. If I ever need another item for my boat or trailer etrailer would be the first place I would look. Thanks again a happy customer.


Extremely happy with site, service and products. Easy to locate parts, great prices, fast shipping and fun tracking map. All parts fit & match well. Gave my trailer 1" lift and stiffer ride.


Needed to replace these on a 1993 boat trailer and was apprehensive, to say the least, on finding a match. Site was easy to use, informational as to dimensions and the like, and the springs ended up being an exact fit for what i was replacing. Delivered in a very timely manner with no issues, even during this eventful place in history. Will recommend and shop here again for sure.


This was a difficult product to find. After a couple rounds of getting the wrong spring elsewhere, I tried etrailer and got the springs I needed. Parts were as described and fit perfectly.


These springs were a perfect fit and easy to install. I replaced the bolts and shackles as well for a complete new suspension on my boat trailer.


All the replacement parts I needed including these springs have performed very well. I'm very happy with etrailer and the products I purchased. Thanks.


The leaf springs I ordered match up perfect for my homemade trailer. Super stoked.
Shipping was quick and on time.
Thank you


My boat trailer spring broke on a 400 mi trip. I was able to nurse it home. I found e trailer on line, very simple to find and order proper replacements. As soon as I ordered I got a confirmation and a shipping upgrade at no extra cost.


I dealt with Chrystal; very helpful and professional. The trailer parts arrived promptly and in good condition. I would buy from etrailer again. Today I ordered steel and will begin building a 5X8 utility trailer.


As I have come to expect E Trailer has delivered on time and in good condition. The leaf springs fits perfectly and my trailer is on the road again.


The leaf springs arrived quickly, and were the exact make sold by a reputable local firm. I used them to replaced broken springs on my old trailer. They and fit well. I now have an operable and safe trailer again. Thanks etrailer.


Nice solid spring. Time will tell how the coating holds up to salt water use. I like that several load ratings are available in this length, so I can easily order and install heavier springs if I put a larger boat on this trailer.


I buy a lot online and this gets a 10 for prompt deliverly. installed easily and works trailer is new again.wiil buy from again.


Parts came faster than expected and were what they were advertised to be. I priced the parts around and etrailer had best overall price including the shipping.


Product was easy to install and has performed well for trailering my boat. etrailer has provided very good customer service.

  • Can 2,000 lb Trailer Leaf Springs be Replaced with 2,500 lb Leaf Springs
    You certainly can go with a 2,500 lb rated axle leaf spring on a trailer that currently have 2,000 lb capacities. It would just give you a slightly stiffer suspension setup. You should note that doing this does not give you any additional weight capacity for your trailer. The weight capacity for a trailer is determined by several things like the axle capacity, brake capacity, coupler capacity etc. The part # SP219275 that you referenced would be a great 2,500 lb leaf spring. It measure...

  • Determining the Leaf Spring Drop From an Empty Trailer to a Fully Loaded Trailer
    The drop that you will experience with the 3-Leaf Double-Eye Spring for 2,500-lb Axles, # SP-219275, from a trailer at zero load to full load is going to be 1-1/2 inches. A few things to note with a fully loaded trailer is that you will want at least 3 inches of clearance above your tires and 2 to 2-1/2 inches of clearance from the top of your axle to the bottom of the frame where the leaf spring hangers are welded. You will also want to get the correct hanger kit for the leaf springs...

  • Double-Eye Leaf Spring for a Trailer Rated for 1 Metric Ton 2,200 Pounds
    Since a metric ton is approximately 2,200 pounds you will need to go with leaf springs that are rated for at least 1,100 pounds. I recommend spring # SP-219275 which is rated for 1,250 pounds. With one of these springs on each side of the trailer the capacity will be 2,500 pounds. I have included a link to a video review of this spring for you and a link to our help article on double-eye suspension.

    In this case I would choose a new set of double eye springs and then weld new spring hangers accordingly. I have attached a link to our double eye springs for you. For example, you could go with the 3-Leaf Double-Eye Spring, # SP-219275, which has a 1,250 lb spring capacity (2,500 lb axle capacity).

  • How Can I Determine The Weight Capacity Of the Leaf Springs on a 1996 Mobile Scout RFK-30 5th Wheel
    To determine the capacity leaf springs you have on your 1996 Mobile Scout RFK-30 fifth-wheel trailer you should look on the frame of your trailer for a plate that will have the VIN number, there should also be a listing for the axle ratings too. You can also tell the weight capacity of the axle by measuring the diameter of the axle. A 3,500-lb. axle will have a diameter of 2-3/8 inches and a 6,000-lb. to 7,200-lb. axle will have a diameter of 3 inches. I am sending a link to an FAQ page...

  • Would Switching to a Leaf Spring with a Lower Weight Capacity Improve Ride of Boat Trailer
    Swapping out your 3500 lb leaf springs for the 2500 lb springs would improve your ride, IF (and only if) the weight of the boat, trailer, motor, gasoline, cooler, tackle boxes, more coolers, fishing poles and other gear stowed on it will not exceed the 2500 lb capacity of the springs. If the capacity is exceeded, you will actually experience a rougher ride as the trailer will bottom out. What is your axle rated for?

    For a 2,500 lb leaf spring we have the part # SP-219275 that would work well. This spring is 25-1/4 inches long. For u-bolts we have a few different sizes depending on the size of your axles. What you will need to do is measure the diameter of your axles and then check out the link I attached that has all of the U-bolts we offer.

  • Can a 4-Leaf Trailer Leaf Spring be Used in Place of a 3-Leaf Spring
    Yes, you can use 4-leaf springs in place of 3 leaf springs. The extra height of an additional leaf is minimal and won't really affect anything on the trailer. Provided that the springs used are replaced in pairs and not just one side of the trailer and they are the right length and capacity for the trailer you will be good to go.

  • 2,500 lb Axle Trailer Leaf Spring Recommendation
    As long as you stay under the capacity for the springs you are fine. They are designed to be safe and reliable up to their capacity so going with heavier duty springs doesn't really gain anything. It just might give you a harsher ride quality. We have 2,500 lb axle springs as part # SP-219275 which would work well for you. These are 25-1/8 inches long.

  • Leaf Spring Recommendation for Boat Trailer with 4,425 lb Capacity and 26 inch Long Springs
    You are on the right track for picking out springs. You would want to split the total trailer capacity in two and then go with that number when picking out springs. Our springs are rated per axle though. The closest to that would be the part # SP-219275 which is a 2,500 lb axle spring that measures 25-1/8 inches in length. Springs tend to stretch over time so yours being older and 26 inches would match well with this.

  • Spring Rate and Deflection of Universal Group SP-219275 2500 lb Leaf Spring
    I managed to reach our contact at the Unversal Group, the manufacturer of the # SP-219275 2500 lb leaf spring. You're correct, the capacity of a pair of springs is 2500 lbs so the capacity of each spring is 1250 lbs. The spring rate is 780-960 lbs/in. The deflection, at the rated capacity of 1250 lbs, should be around 1.43 inches. This would result in a loaded height around 1.75 inches.

The ride might be a bit stiffer but it would still work well. The 2,500 lb axle springs we have are longer like the # SP-219275 which is 25-1/8 inches long and would require moving you hangers. You'll want to replace the springs as a pair for the axle. Since the springs would be different rating you'll want to replace all of them so they all match.
