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.

Seems to be a great product. I've had them for a year now. I tow my Polaris xp4 around with my trailer equipped with the springs. trailer rides and tracks well. I would recommend this to anyone building or respringing a trailer.

The quality of the springs is very good. The center pin and nut fit right into the spring perch and spring plate and the length was perfect for my application.

Alex was very helpful in answering my questions and providing the correct parts for my repairs. He even provided some videos to make the installation easier. The parts were delivered on schedule and undamaged. The whole process was as stress free as could be expected with my limited experience and mechanical skills.

  • Recommended Leaf Springs For 16 Tiny House Trailer With Tandem 3500lb Axles
    Ideally you want the leaf springs to be a few hundred pounds overrated for what you are planning on carrying to make sure the springs will not be too stiff. As long as your trailer is in the 4000-4500lb range I would go with the 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 23-1/8" Long # e59SR which has the 1750lb rating per spring you mentioned. These will not be overly stiff and will make sure your tiny house has enough support. If you will be towing it often and not just taking...

  • Replacement Leaf Springs For a M116 Military Trailer
    The only information I was able to determine on the M116 military trailer is it uses double eye leaf springs and has a total trailer weight just over 3,000lbs. We currently offer 3,500lb leaf springs in a 23-1/8" # e59SR, 25-1/8" # e54SR and 27" # e97SR length. These lengths are measured from center of the eye to center of the other eye bolt holes. You will want to raise the weight off the suspension before measuring your current springs to get the most accurate measurement. If the measurement...

  • 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 # e59SR which measure 23-1/8" long.

  • Replacement Bearings and Suspension Components For a 2016 Forest River Wildwood X-Lite 261BH
    If you are just going to be cleaning your hubs and packing the bearings with fresh Grease # L11390 you will want a set of Seals # RG06-050 for each of your 3,500lb axles. The Seal Puller # PTW1219 will make removing the seals easier once you have your hubs removed. We do offer the Bearing Packer # L70025 which will allow you to more easily squeeze the fresh grease into the bearings with the aid of a Grease Gun # L30416.

    If you are using the Single-Axle Trailer Hanger Kit part # APS3 with the 3-Leaf Double-Eye Spring part # e59SR then you will need to install the leaf springs hangers 22-7/8" apart. In regards to spacing front to back, I have attached a help article for you that will help with this.

  • Replacement Leaf Springs for Cargo Mate Enclosed Trailer
    It is certainly possible that the springs have already worn out. One way or another, the leaf springs on your Cargo Mate enclosed trailer definitely should not be flat. Assuming you have the original hangers and shackle strap on the trailer and they were not replaced along with the leaf springs, I would say the worn out leaf springs are the reason you have lost the clearance with your axle. From what I have found, it looks like your trailer has a 3,500 lb axle. I recommend verifying this...

  • Are Shackle Straps Included With Universal Group Leaf Springs
    Shackle straps are not included with the 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 23-1/8" Long # e59SR. You will want to buy shackle straps based on the length of your current shackles. This is the center of bolt hole to center of bolt hole measurement. Since you are looking to buy new shackle straps, it would be a good time to upgrade to heavy duty shackles straps and wet bolts. For example, if you have tandem axles with 2-1/4" long shackle straps you would need the MORryde...

    The size of the replacement leaf springs on your 2012 Keystone Cougar 27RLS should be the same as what you have now. To be more specific, you need to match the length as well as the axle capacity. Based on the weight of your trailer it looks like you have 3,500 lb axles but I would check the axle tag to be sure. The length is something you will have to measure. The standard is the spring eye to spring eye measurement. You can also use the flat measurement since your leaf springs will...

  • 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 3-Leaf Double-Eye Spring # e59SR 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 your existing...

I've also attached an article on double-eye trailer suspension systems for you.

  • Recommended Replacement Spring for a 2021 Coachmen Freedom Express Travel Trailer
    Yeah, I agree if you are sagging on one side you've got a spring issue. We do not have any springs that would be a step up from the Dexter 072-013-00 you currently have installed. That spring is 20-1/2" long and rated for 1,400 lbs per spring. Our closet option is the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles item # e84SR but they are only rated for a 1,000 lbs per spring. That won't help the problem. To add longer, resulting in higher capacity, leaf springs you would need to...

  • Replacing 24 Inch Long Leaf Springs on Trailer with Dexter 3,500 Pound Axle
    The closest option we have to the measurements you took on your existing leaf springs is the 3-Leaf Double-Eye Spring # e59SR. This 3-leaf stack measures 23-1/8 inches from the center of one eye to the center of the other and is designed for a 3,500 pound axle. Older leaf springs will stretch over time so it's not abnormal that the new leaf spring will be shorter than the measurement you took but I do still recommend verifying the length on your current springs.

  • 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...

    Thanks for reaching out, we definitely can help you with a replacement double eye leaf spring!

  • 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 # e59SR 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...

  • Trailer Suspension Parts Needed to Increase Trailer Capacity from 7000 to 10000 lbs Gross Weight
    Your best bet for upgrading the suspension on your trailer with 5,000 lb axles is to change out the springs from 1,750 lb capacity each to at least 2500 lb capacity each. Helper springs would not increase the capacity of your original suspension, they are designed to help your suspension handle loads up to the rated capacity of the suspension. If your trailer suspension is built with double eye springs you will need to measure the springs with no load on them from the spring eye center...

  • Broken Leaf Spring Replacement Recommendation for 23-1/8 inch 2,500 lb Axle Springs
    If you don't want to move your current hangers we have a 3,500 lb axle leaf spring part # e59SR 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 # e66SR 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.

  • Is There an Advantage to Going to a Higher Rated Leaf Spring with a 3,500 lb Trailer Axle
    There really wouldn't be a benefit. It would unnecessarily stiffen up the suspension. You still would be limited by the 3,500 axle capacity so you wouldn't gain any capacity while increasing the stiffness of the trailer suspension. Best option is to stick with 3,500 lb leaf springs. For 3,500 lb springs we have the part # SP-210275 for a 27 inch long spring, part # e54SR for a 25-1/8 inch spring, or part # e59SR for a 23-1/8 inch long spring.

  • 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.

These are specifically designed to fit with the 42" axle center spread you have on your Bullet. I recommend also changing out for the Wet Bolt Kit # MR46ZR which will allow the suspension to more easily move throughout its range.

  • Should All Trailer Leaf Springs be Replaced at Same Time
    Your best solution is to replace all leaf springs at the same time with the exact same spring. This will ensure everything rides as predictably as possible and prevent one axle from hanging lower than the other based on different thickness leaf springs. For 3,500 lb axles the part # K71-384-00 is the correct over-under kit. We have a few 3,500 lbs springs too. For a length of 25-1/8 inch you'd want the part # e54SR, for 27 inch # SP-210275, and for 23-1/8 inch # e59SR.

    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. Jack the trailer up so that the spring no longer has a load on it and measure it. Subtract around 3/4 of an inch since springs flatten and stretch out over...
