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.

Always very communicative customer service. Received/packed/shipped my order on a sunday(unheard of). It was delivered two days later. And that was the free standard shipping. I wish I had a need to do business with etrailer more frequently.

Service was fast,appeared to be quality .im not happy with the springs after a year.my boat and trailer weighs 4200 lbs and the rated gvwr on the trailer frame is 5000lbs.i replaced my original single leaf springs with the 3 leaf from etrailer,4 at 1250lb each should have equalled my gvwr and exceeded my boat weight.they appeared fine at first but gradually over the year they started sagging and my shackles started hitting the frame.the springs visibly flattened and lengthened causing the problem.after calling etrailer they informed me there is no warranty and nothing they can do.i think their spring rating is a bit off.im going with slightly heavier springs next time



by:

Outstanding products and staff my go to website before anyone else this particular project I ordered the wrong springs, I call etrailer expecting to eat the cost of my mistake and instead they sent me a return label for the return of my mistake and they immediately sent me the correct springs which I received in a couple days, this is why I continue to support etrailer because they support me.

  • 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 # e66SR 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.

  • Can Unique Leaf Springs be Replaced on a Very Old Trailer
    I believe the hubs are for 2,000 or 2,200 pound agricultural axles which is why the springs look so different. These hubs are designed for very low speed applications (5 to 10 miles per hour according to HADCO) so if you plan on going faster than that you will need to look at replacing the axle and hubs. You could use 2 of spring # e66SR. Each spring has a capacity of 1,250 pounds. If a new hanger kit is needed you can use # APS1. When used with spring e66SR the center to center distance...

  • What is the Correct Distance Between the Spring Hangers When Using a e66SR Leaf Spring
    The distance of 25-3/4 inches would be the correct distance to have between the spring hangers. You have to consider that as the the leaf spring compresses from the weight of the trailer it will flatten out and the overall length of the spring will increase so that the shackle will face the right direction.

  • How Close to Trailer Weight Should Capacity of Trailer Leaf Spring Be
    Our trailer leaf springs are rated for dynamic axle load. Which means the capacity listed but in use on the highway under normal circumstances. Since your trailer is 2,200 lbs loaded you want to go for a spring capacity 2,200 lbs or slightly higher. For you second question it sounds like your springs are worn out. You do want to have 4-1/2 inches of fender clearance between the fender and your tire when the trailer is unloaded. Ideally you are within a couple hundred lbs of the total...

  • 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 # e66SR 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.

    For your 1998 Flagstaff pop-up camper. M.A.C. Model 206 the replacement leaf spring part # e66SR would be your best option. It's for a 2,500 lb axle and has a 25-1/8 inch length which would work great for what you have.

  • Picking Out Trailer Leaf Springs for Trailer with 30 inches between Hangers
    To pick out the correct suspension components for a trailer you want to do it by most importantly picking out the springs that closely match the capacity of the axle capacity needed. That is priority one. For example if you were using the springs part # 1020, # e66SR, # e34SR, # e28SR, or # e57SR with the hanger kit part # APT5 that comes with equalizers that are 7-3/4 inches long you would want the hanger spacing to be 29-1/2 inches which is pretty close to what you have. All of these...

  • Replacing Suspension Components on Old Motorcycle Trailer
    It will be time to update your suspension on you motorcycle trailer. Current leaf springs for trailers are all 1-3/4" wide. To update your trailer you will need a correct Spring Hanger Kit # APS2. This will give you new hangers that will need to be welded to your frame. These will fit inside where your old mounts are as the new leaf springs will be much shorter. I have linked a help article below that will help you with the suspension systems on trailers.

  • Replacement Double Eye Leaf Springs For a 2003 Tracker Trailstar TV-18 Boat Trailer
    It sounds like you will most likely need the 3-Leaf Double-Eye Spring for 2,500-lb Trailer Axles # e66SR for your 2003 Tracker Trailstar TV-18 trailer. This leaf spring has a eye to eye center length of 25-1/8". Your spring is likely sagging a bit to give you the 25-5/8" measurement. Be sure to check the information sticker on the front of your trailer to verify this spring is the correct weight capacity as well.

  • 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 # e66SR which would work well for you. These are 25-1/8 inches long.

  • Hanger, Leaf Spring, and U-Bolt Kit Recommendation for Dexter Axle # 20545I-EZ-60-15
    The Dexter axle part # 20545I-EZ-60-15 is a 2,200 lb axle so for springs you'd want the 2,500 lb spring part # e66SR which is the closest we offer to a 2,200 lb axle spring. Then for a u-bolt kit you'd want the part # APUBR-10. The part # APS4 would be a great single axle kit to use as well.

  • Does 3-Leaf Slipper Spring w/ Radius End Require a Bushing for Rear of Spring
    For the 3-Leaf Slipper Spring w/ Radius End # e99SR you only need the bushing on the one end, the other end will either sit over a bolt or will fit into a hanger like part # 115706S. If you have a double-eye spring on your trailer then you'll need something like the 25-1/8" Long 3-Leaf Double-Eye Spring # e66SR instead. Attached are some videos for you to check out as well.

  • 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.

    If you have the leaf spring part # e66SR that you referenced which is 25-1/8 inches long the center to center dimension you'll need to use for the spring hangers would be 25 inches. This would be the same for the leaf spring part # e54SR you mentioned as well.

    The closest match that we currently have to the leaf spring that you are looking to replace is either part # e77SR which is rated for 2,000 lbs or part # e27SR which is rated for 4,500 lbs. They both are double eye leaf springs that are 26 inches long but they look like they fall outside of your weight range and they both have 4 leaf springs instead of 3. For a 2,500 lb 3-Leaf Double-Eye Spring we have part # e66SR which measures 25-1/8 inches on center. For a 3,500 lb 3-Leaf Double-Eye...

  • 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 # e66SR that you referenced would be a great 2,500 lb leaf spring. It measure 25-1/8...

  • Trailer Leaf springs # e54SR Recommendation for a 2005 Bri-Mar Open Car Trailer CH16-7
    For your 2005 Bri-Mar open trailer model CH16-7 with GVWR of 7,000 lbs I would recommend you get 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles, part # e54SR. These leaf springs are designed for use on trailers with 3,500 lb axles like what you should have on your trailer. You should note that leaf springs have a tendency to stretch out over time, so the fact that these leaf springs are a little bit shorter than your current springs at 25-1/8 inches these would be the correct length....

  • Comparing Amount of Drop of Torflec Axle with a Drop Axle

When it is under a full load it will sit about 1.45" above the bottom of the frame of your trailer. If you are wanting a Torflex axle that sits lower then you need the 22.5 degree which has the center of the spindle sitting about 0.52" above the bottom of your frame under no load.

  • Replacing Inverted Leaf Spring Suspension on Old Utility Trailer
    The first thing you will want to do is to remove the current springs from the frame and the axle. You can still use your axle if it is in good working order, but you will also want to remove any hardware welded to the axle. To install leaf springs, you will first want a hanger kit. For your single axle trailer, I recommend Redline's Single-Axle Trailer Hanger Kit for Double-Eye Springs # APS1. This hanger kit will have a 1-1/2 inch drop for the front hanger, and a 7/8 inch drop for the...

    If your trailer truly has a front and rear bracket for double eye springs you can absolutely use the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 you were looking at as a replacement. With that said while the hangers may look alike, they are typically not the same. This spring is designed for 3500lb axles so you will want to make sure that your trailers axle has the same rating.

  • Replacement Leaf Spring Recommendation for Trailer with 25-1/8 inch Springs and 2k Capacity
    Most likely the measurement is 25-1/8 inch as that is a common size. But in most cases we recommend measuring the spring with it off the trailer and typically there is a bit of stretch to old springs by around 1/2 inch or so. The spring you would want is the part # e66SR as it matches the capacity needed closely and it has a length of 25-1/8 inches like you have. When picking out leaf springs priority one is picking out the correct capacity and then finding a spring that is close to it...

    Looking at the specs for your 2006 Starcraft 2406 pop up camper it looks to have a 2,500lb axle. The only double eye leaf spring we have with that weight rating is the 3-Leaf Double-Eye Spring # e66SR which has an eye to eye measurement of 25-1/8". Since this measurement is for the spring without any weight you are best to measure from the center of the spring eye to the spring center along the radius of the spring since the spring center to spring center will get longer when weight is...

  • 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.
