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.

These parts were for a 1977 Citation Travel trailer frame that someone had cut the springs off because the electric brake drums were to tight to roll and quite rusty so adjustment was not practical in the field.The springs and assembly pieces arrived promptly. The installation was completed in one hour. All parts fit exactly as they should. The goal is to make a storage trailer unit 8 X 18 feet.


Upgrading the suspension on my 2006 Fleetwood Pioneer 250FQ travel trailer.
Everything went together flawlessly.
Thanks eTrailer for excellent customer service! Paula S. was very helpful!


Allo tanks for fast delivery I’m appreciate your good service and esy tracking and I’m received 2 good parts


Good quality replacement for the money. Spring is ruggedly designed. Fit the trailer frame as measured.


Theses springs were exact replacements for my 20 year old Mallard that had suffered a broken spring. Tremendous value, I bought all 4 springs with replacement greasable bolts and new bushings for less than a local rv shop wanted for just one spring. My feeling was that if one spring had let go what other springs had leaf cracks as well? With this price, replacing all 4 was a no-brainer.

We upgraded our camping trailer last fall so I’m no longer in a position to do a follow up review. Sorry, but the parts worked great while we owned it and gave piece of mind on the road. Thanks again for the parts and service you folks provide, you’re top notch in my opinion!

I haven't installed them yet because of the weather. When I do I will take pictures and add them to my review.

Everything went very well. No problems encountered while installing the equipment. Installed on a 1992 Lance 5th Wheel.
Loran B - 03/18/2018


Easy install, perfect fit.


Fast delivery easy install. Made my rv level and smooth riding


Excellent selection, price and customer service


Was all there, packaged well great to find parts like this


This is my 3rd item ordered from etrailer, and I will be back when necessary! The customer service is great and the products have all worked very well. I was even offered earlier shipment for being a repeat customer! That was a nice surprise


The replacement trailer spring set was out of stock but Michelle watched for it with care and kept me informed. She let me know when it came in, shipped it quickly and made sure I had all the nuts and bolts needed to replace my broken springs. Have ordered from etrailer in the past and the quality and price can't be beat.


From ordering to installation and use , it's been a pleasure doing business with e trailer. They make sure I have the correct part even the part was quality.


They look like really solid leaf springs they got hear at a decent time. But I can't use them cause I ordered them to smale. I needed 33 1/2 not 23 1/8 and wrong size bolt eye mine was 1/2 and width was not 2 inch but I was just going to get spacers


I have had these for about a year on my dual axle travel trailer. Trailer weight is usually around 6000 lbs when towing it. I camp out in the middle of nowhere and go over some "roads" most wouldn't want to take. These springs have not had any problems so far.


This product was just what was needed to rejuvenate my old trailer. It rides (firmly) like new again. Easy to install with the trailer on its side.

The new springs are still like new and working well
Michael - 08/26/2019


Working like a champ!


Fits /matches exactly what I needed from an older Tandem axle Terry 5th wheel. Hard to find, but etrailer had it no problem.


Worked very well on a homemade trailer I had purchased that they used a "trailer house" axle and single spring set up that was not providing any spring action at all. I should of also ordered shackle bolts with the springs. Old ones were rusted terribly and were a bear to get off. Bought new shackle bolts locally to replace. Trailer rides much more smoothly now. Thank-you. Wish I would of taken before and after pictures but I forgot to do that. I highly recommend etrailer for your selection, reasonable pricing and fast shipping. Thank-you!


I was impressed with the fast service. They have a wide selection of parts that you can't find on other sites.


I just got them installed so I will tell you after I get back to Massachusetts. About 1200 miles from Nashville Tennessee.
I appreciate the super fast delivery! Thank you


The springs I replaced in the older 36ft fifth wheel camper we had arrived quickly and fit perfect at an excellent price. We camped the rest of the season and sold the camper to some people out of state and it pulled great with not a problem home for them as well. Will definitely be were I order my trailer parts from in the future.


One of the springs on an older 29ft travel trailer broke so I replaced all 4. It has been over a year now and they are holding up great. Happy camper!


Springs were purchased to convert a dollie to a sprung trailer. They were easy to install and looks like they'll do just fine. Delivery was right on time and all went together a-okay. Good people to do business with.

Just fine - no problems.
Robert H - 09/08/2018


These springs have performed great. Perfect it and keep my tandem axle trailer towing straight and true. Trailer tires are wearing perfect.
I have peace of mind knowing spring issues are solved and I can tow with confidence.
Thanks for great products!

  • How to Get Correct Length Measurement of Trailer Leaf Springs
    I'm assuming that you're wondering how much the leaf springs flatten out over time. Usually it won't vary by more than 1/2 inch or so, but there's a sure way to get an accurate measurement. The best way to get an accurate length measurement for a leaf spring is to jack the trailer up so that the axle is hanging free. You can then get a center eye to center eye distance that'll be right on the money. By letting the axle hang, you'll be able to get a correct measurement.

  • Correct Replacement Leaf Spring for 2,800-lb Dexter Axle
    The distance between the spring eyes should be measured from the center of each eye. I've attached an image showing the correct locations to measure to obtain leaf spring measurements. However, from the given information, it sounds as though you have the correct replacement part with the 3-Leaf Double-Eye Spring # SP-216275. I've also attached an article on double-eye trailer suspension systems for you.

  • 3,500 lb Leaf Spring Availability that is 23-1/8 inches Long
    If you dimensions all match the part # SP-216275 except the height from the pin to the eyes is a bit less (they flatten out over time), this spring will still fit and work well. Especially if you have a load on your trailer as well. The two big things to use when picking out leaf springs is the length of the spring as well as the axle capacity. This is for a 3,500 lb axle. If that matches your trailer this is just what you need.

  • Replacement 23-1/4 Inch Leaf Springs for 1984 Prowler Trailer
    If your 1984 Prowler Trailer has 3,500 pound axles, I recommend sticking with a 3-Leaf spring like the Universal Group 3-Leaf Double-Eye Spring # SP-216275 to replace your 23-1/4 inch springs. This leaf spring measures 23-1/8 inches from eye to eye, which will give you a much better fit to replace the existing springs on your trailer. A leaf spring of closer to 25 inches might be too long for the current hanger setup on your trailer. Older leaf springs will elongate a bit over time, meaning...

  • What is Recommended Clearance between Trailer Axle and Frame
    The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.

    In order to pick out the correct springs we need a couple pieces of information. The length of the spring without a load on it and the axle capacity needed. Your springs being totally flat does indicate that you need to replace them but I would need to know the unloaded length from spring eye to spring eye and then the axle capacity.

  • Replacement Leaf Spring Recommendation for Trailer with 3,500 lb Axles and Length 23-1/4
    Springs tend to stretch over time as they wear out and flatten. This means that you need to go with springs that are slightly shorter than what your old springs measure. For that the best option is the 3,500 lb leaf spring part # SP-216275 which measures 23-1/8 inches. This will work great as a replacement for the spring dimensions you mentioned. Around 1/4 inch shorter than the worn out spring is the best option typically. But that's not a hard and fast rule so for your situation the spring...

  • Hanger Spacing When Using 23-1/8" Double-Eye Leaf Spring on Single Axle Trailer
    On a single axle trailer you will want to have a hanger spacing of around 22-3/4 inches when using the 23-1/8 inch long Double-Eye Spring # SP-216275. This will allow that rear shackle to correctly lean away from the axle for proper suspension travel. I have attached a short video review on this leaf spring that you can check out as well.

  • Replacing Suspension On A 1995 Mallard 23P Travel Trailer
    Before removing and potentially replacing the leaf springs, trailers sometimes lean to one side because of the way it's loaded. This uneven loading can cause the leaf spring to wear down quicker over time but could maybe be corrected by reorganizing the weight in your camper. Given it's a 1995, it could just be time for replacement as well. Trailer leaf springs need to be selected based on the axle weight rating, as well as on the spring type (slipper or double-eye), length and width dimensions....

  • Correct Replacement Leaf Springs for Trailer with Dexter 3,500 Lb Axle
    In order to find the correct replacement leaf springs for a trailer you'll need to know the type (slipper/double eye), weight capacity, and unloaded length. The springs will stretch over time so the new replacements will be shorter. If you have a 3,500 lb axle with double eye springs then you'll likely need 3-Leaf Double-Eye Spring part # SP-216275 which measure 23-1/8" long.

    We can help you with new double-eye leaf springs for your boat trailer with 3500-lb tandem-axles. Usually axles will have a plate or sticker that tells you their weight rating. Old, worn springs tend to stretch. If you remove one of your leaf springs and measure its eye-to-eye dimension it is entirely possible that it will now measure longer than it was when installed. If the spring is still installed in the suspension it is hard to get an accurate measurement unless you jack up one side...

  • How to Measure to Select Correct Replacement Leaf Springs for Utility Trailer
    The best way to measure your springs is to remove one from the suspension so it is no longer under tension. This way you can accurately measure its eye-to-eye length. If your hangers are 25-1/4-inches apart chances are that your spring would be 23-1/8-inches, such as # SP-216275 which is indeed rated for 3500-lb axles. Keep in mind that swapping out trailer leaf springs or the axle may not actually increase the capacity of your trailer. This would be the case only if you knew for certain...

  • Troubleshooting Reduced Fender Clearance After Replacing Leaf Springs
    It's certainly possible that you have two identically rated and sized leaf spring sets on your trailer that feature a different amount of leaves. Most likely at one point only one side of the trailer leaf springs was replaced, while the other remained installed. We do recommend replacing both sides of the leaf spring sets on an axle at the same time. As long as you get the needed capacity and length, there is not really an advantage with going to a set that features more leaves. The additional...

    If you don't want to move your current hangers we have a 3,500 lb axle leaf spring part # SP-216275 which would fit and would work well. 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.

  • Replacing a Broken Leaf Spring on a 2007 Starcraft 2406 Pop Up Trailer
    When replacing a broken leaf spring on your trailer there are a few things to note. The most important part about a leaf spring being compatible with your trailer is that it is rated for at least the same weight capacity as your trailer axle. If it is rated lower you could overload it. A higher rated leaf spring would work but it would also make your trailer suspension stiff. Other than weight capacity you simply need to make sure that it has the correct width, is the same style, and has...

    Unless you didn't need to take full advantage of the 2,630 lb axle capacity of your trailer the part # SP-169275 would not work. If your trailer would never see more than 2,000 lbs this would work well. A better option would be the part # SP-216275. This is a 3,500 lb spring and is a tiny bit shorter at 23-1/8 inch which will work great for you since springs stretch when they are old.

You will have to move your hangers out 2-1/4 inches for this spring to fit but since it's the correct axle rating it is the best choice. The leaf spring you mentioned has a 2,000 lb axle capacity so it wouldn't be safe for you to use.

You're probably going to need to use the # SP-212275 as a replacement. I'd recommend staying with your current setup, but I would check your shackle links to make sure they're still in good shape, the bolt holes should still be round, not wallowed out.
