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.

Having never replaced a leaf spring before I decided to go ahead and give it a shot on my own. I reviewed the information on etrailer.com and found the replacement parts without a problem. Once they arrived I removed the old worn leaf springs and replaced them without much trouble at all. Back to safe trailering. Thanks etrailer for the help.

I purchased the 3000# axle springs and all mounting hardware to replace the old ones on my 1963 travel trailer. My trailer no longer leans to the left and goes down the road better than new. I should have done it many year ago. I received my package on time and installation was easy and fit perfect. Thanks Bridget

I completed construction of a mobile bandsaw mill and found the springs on the mobile home axle I used were much to strong. I believe they were rated for 6,000 pounds and did not flex with the light load of the bandsaw mill. The SP-210275 were a perfect fit for my need. Shipping was very quick and other than needing to purchase longer "U" bolts, I was able to simply remove the old springs and bolt the new springs right into place. Very satisfied with this purchase and installation.

I discovered that I needed to fit the holes in the bottom of my axle onto the studs on the springs before tightening the hardware fastening the springs to the rear shackles and front hangers.
by: Jeff 09/08/2023
The spring arrived earlier than I thought it would. Looks like it will fit and do the job. I purchased the leaf spring as an emergency back up in case on breaks on the Trailer. E Trailer hasn't let me down.

With the outstanding help from Tommy at etrailer.com, I was able to purchase the right axle, hubs, spring and tires the first time. Everything arrived in good condition, went together like a dream. I was impressed with the quality of product and service.

The product was correct but the ordering was next to imposible. It took weeks longer than necessary. It wasn't until I was refered to Mgmt. that my order was resolved, gratefully. All in all the 2 day project took 3 weeks. Still upset a year later.

Great product! My first purchase from etrailer but it won't be my last! etrailer seems to have everything you would need for your RV or trailer. Waited until the last minute to pick up an extra leaf spring for my trip to Alaska. Fast shipping got it here in plenty of time. Thanks!
by: Corey03/01/2018
Great service. I know that I needed to do something to my trailer but I had no idea where or how to get the right parts Everything was too rusty to find any part numbers. I sent them a few pictures and gave them the measurement that they asked for and in about 30 mins I had a complete parts list of what I needed. When I got the parts everything was correct and fit great. Will defiantly be ordering from them again. Preston, and Jessica B were very helpful....

I rebuilt my little 5x8 utility trailer with parts from you guys and its been holding strong. Thanks for all the help. I went into this build without knowing much about suspension and you guys were a big help at getting the right parts.
by: Mark08/25/2018
All Parts arrived as ordered and their quality and type is as expected, thank you.
However, I would suggest better packaging when shipping leaf springs. The loose nature of the packaging seems to have caused the leaf springs to puncture the box causing a 2 day delay in shipping and the potential loss of my other items.

Replaced a older set on a trailer with no specs. Bought the length closest to what I had, but a higher weight capacity. Replaced the axle to a 3500 lb one too. Have more confidence in the trailer now and I know it's a lot safer. How do these compare to others? I don't know. It's very hard to find these things locally and few sites have as good videos as etailer. These guys seem to know their stuff. There was lots of specs on these items at this website so I felt confident planning and executing the trailer upgrade.

It was the perfect size and fit right up. I bought it for my 1963 2 horse trailer with random axels and it worked great. Thank you.

Worked and fit great, I’m sure it will continue to work great for years to come. I love the fact that you took the time to follow up.

Have never bought from this store before . The parts were here quickly and the customer service was great right parts the first time. I will have to see how the parts hold up before I can say how good the quality is

I appreciate your follow up. I no longer have the trailer I bought the parts for. I, however, was very pleased with the quality of the parts while I had it. I have replaced that trailer with another one and don’t doubt that sooner or later I will be needing something for it that I will return to etrailer for.
by: Thomas 11/02/2019
Thank you etrailer!
The shipment arrived sooner than expected, the leaf springs along with a hanger kit arrived in a heavy duty box with very good packaging. As for the leaf springs they're heavy duty thicker gauge compared to the ones currently on my utility trailer. With beefing up my suspension I'll be able to raise my box and carry a heavier load with my current axle.
by: Dave H.03/13/2017
Well, I just got the parts, so can't say anything reliable on chinese made parts.
The price was(is) Great! a boat load cheaper then the local store....humm.
springs fit perfectly, however, the springs I wanted are no longer being offered, could of had springs made but I went with the less$isMore theory. (more in my pocket)
The "white" nylon bushings I ordered would not fit into the equalizers, but the grey colored ones I had did fit perfectly, just a-hair difference in outer diameter.
The bolts fit perfectly as well.
It is always 10 times easier dealing with eTrailer then the local store, So I know eTrailer has put a lot of time into making it easy for their customers, Thanks!
Very Fast shipping, all at a price I can afford!

- Leaf Spring Recommendation to Replace 27 inch Long Spring on Camper with 1,500 lb Trailer WeightLength-wise the leaf spring part # SP-210275 that you referenced is about right at 27 inches. Since your trailer only weighs 1,500 lbs though this is going to give you a somewhat rough ride quality. A better option would be # e77SR most likely as it has a 2,000 lb axle weight rating and is 26 inches long. I know that's an inch shorter than what you listed, but leaf springs stretch out over time as they wear out so your 27 inch springs were most likely a bit shorter when new like this spring.
view full answer... - Replacement Leaf Springs for Dump Trailer with 3500-lb AxleIf your 10-foot dump trailer was made with a 3500-lb axle you cannot double its weight capacity just by swapping out the leaf springs to higher-rated ones. Any trailer's rated weight capacity depends on all of the component parts used to fabricate it. These include the trailer frame, the dump bed itself, the axle and suspension and even the specific hubs, wheels and tires on it. Changing one of these components to another with a higher rating does NOT mean that the entire trailer now has...
view full answer... - Suspension Solution for Trailer with 3,500 lb Axles to Smooth Out Ride QualityLonger springs really aren't going to smooth your ride quality out a noticeable amount. Trailer suspension is typically pretty bouncy or rough due to the fact that there is no shock on the springs to dampen or slow the movement of the suspension. The solution for that is a shock kit like the part # LC281255 which is designed to fit 2-3/8 inch diameter axles like what are commonly used for 3,500 lb axles.

The 27 inch leaf springs we carry for 3,500 pound axles is # SP-210275. The bolt with locknut you need is # 166081.

- Estimated Weight rating for 1-1/2-Inch Square Trailer AxleTrailer axles will often have some kind of labeling on them to indicate their weight capacity, sometimes a sticker but sometimes a metal plate too. If very old that axle sticker or plate could be long gone. The 1-1/2-inch square axle we offer, CE Smith Trailer Axle # CE33201GA-HUB, is rated for 1800-lbs and includes 5-on-4-1/2 idler hubs and also comes with bearings, races, seals, grease caps, wheel studs, lug nuts, and marine-grade wheel bearing grease. This axle has a hub face spacing...
view full answer... - Replacement Leaf Spring Recommendation for a 3,500 lb Dexter AxleFrom the info I was able to find on the number you listed you do have a Dexter 3,500 lb axle so for a leaf spring you would want the # e54SR for if you need a 25-1/8 inch spring or # SP-210275 if you need a 27 inch leaf spring.
view full answer... - Leaf Spring Recommendations for 3,500 lb Trailer AxlesIdeally you match the leaf spring's axle capacity with the axle capacity of the trailer. So since you have 3,500 lb axles you would want 3,500 lb axle leaf springs. Typically the springs are all rated for the capacity when used in a pair. We have three that will fit that capacity that are varying lengths. We have the part # e54SR which is 25-1/8 inches long, # SP-210275 which is 27 inches long, and # e59SR which is 23-1/8 inches long.
view full answer... - Recommended Replacement 3,500 Lb Axle With Brakes For TrailerI recommend an axle like part # 35545E-ST-89. This axle has a distance of 89 inches hub-face-to-hub-face and a spring center-to-center measurement of 74 inches. The brake flange-to-flange distance is 82-5/8 inches. The axle has 10 inch x 2-1/4 inch brake drum dimensions and a 5 on 4-1/2 inch wheel bolt pattern. This will accommodate 13 to 15 inch diameter wheels. Based on the measurements you provided, this will work well for you. This axle comes with brakes, hubs, drums, bearings, races,...
view full answer... - Is There an Advantage to Going to a Higher Rated Leaf Spring with a 3,500 lb Trailer AxleThere 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.

view full answer... - Recommended Leaf Spring Replacement For A 1999 MFI Boat TrailerTo replace your current 26-3/4" double-eye leaf springs I recommend the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275. It is slightly longer at 27" but are flexible enough to still work for your application with no problems.
view full answer... - What Would Cause Boat Trailer Leaf Spring to Flatten OutIt's possible the weight of your trailer and boat is more than the capacity of the leaf springs you installed which is causing them to fail. Most 20 ft pontoon boats weigh around 2,200 lbs so it's very likely with the weight of your boat and the weight of the trailer you are exceeding that figure. So your best option is a new set of springs that are rated higher than the weight of the boat and trailer. The weight capacity figure is more important than matching the lengths as you can move...
view full answer... - Replacement Leaf Spring Options for a 3500 Pound Dexter AxleWe definitely have a few options available for a 3,500 pound Dexter axle. That being said, you will need to measure your current leaf springs to see which one will fit. This should be done going from the center of one eye to the center of the other eye. The 3-Leaf Double-Eye Spring # e59SR will measure 23-1/8 inches from eye to eye, and the 4-Leaf Double-Eye Spring # SP-210275 will measure 27 inches from eye to eye. Both of these option are rated for a 3,500 pound axle and will definitely...
view full answer... - Which Double-Eye Leaf Springs Are Suitable For 5,500lb Tandem Trailer?The 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 23-1/2" # SP-113275 is rated for 1,000lbs each, and since there are two springs per axle the weight capacity would be 2,000lbs per axle. This would not be sufficient for your 5,500lb trailer so you would want a heavier duty leaf spring. I see you ordered 4 of these leaf springs which tells me you likely have a tandem 2 axle trailer. This means each leaf spring must be rated for a minimum of 1,375lbs to be sufficient for a 5,500lb...
view full answer... - Leaf Spring and Hanger Kit Recommendation for a Single Axle Trailer to Replace 37 inch SpringsThe longest double eye spring we carry is the # SP-210275 that is 27 inches long and is the standard 1-3/4 inches wide. The best solution I could provide for you would be to replace the hangers you have now with something compatible with 1-3/4 inch springs and then go with a spring we offer that would work with those hangers. To pick out a spring you will want to pick out a spring properly rated for the weight of your trailer. Check out the link I attached to the right that has a chart...
view full answer... - Should the Space Between Tandem Axle Trailer Tires Be the Same On Both Sides of the TrailerIs there more weight on one side of the trailer? If so, you would want to make sure the load is distributed evenly from side to side. Are you on level ground when you measured the distance between the tires? If not, that would cause one side of the suspension to have more of a load on it. I would measure the distance between the spring hangers on both sides just to make sure the problem is the springs and not where they are attached on your trailer. If everything checks out it might be...
view full answer... - Picking Out Trailer Leaf Springs for Trailer with 30 inches between HangersTo 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.

This is possible but will require you to install new rear hangers for the rear eye of the spring to attach. You would need to go with a leaf spring that is rated for the weight of your trailer when it is loaded an ready to go. The closest leaf spring we have in terms of dimensions that is for a 3,500 lb axle is the part # SP-210275. This spring is 27 inches long. For the price an convenience...
