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.

Video Transcript for Universal Group Trailer Suspension - Leaf Spring Suspension - SP-210275 Review

Today we're going to take a look at the 4-leaf double-eye spring for 3,500-pound trailer axles. This spring is designed to flex to absorb road shock and provide a nice smooth ride. It will help reduce wear and tear on your trailer. It helps you enjoy a level ride on bumpy and uneven surfaces and it mounts to your trailer frame with hangers or a hanger kit which we do sell separately on our website. Lots of times they are listed on this product page as a related product. It does include the nylon bushings in the eyes. A few specs on this.

The spring capacity is 1,750 pounds. It is designed to be used on axles with 3,500-pound rating. When you use this with one on the other side it will meet your 3,500-pound rating. This is for a quantity of one spring. It does have the four leafs as you can see, one, two, three, four.

I do want to give you a few measurements on this. We're going to do the spring length which is measured from the center of this busing to the center of this busing. You can see center-to-center is going to be right at 27 inches. We're going to do the width of it and the width is going to be right at 1-3/4 inches wide. The diameter of the eyes on each end is 9/16 of an inch. I just want to know we do want to recommend is that to ensure proper axle alignment and suspension performance, you do usually want to replace your leaf springs in pairs.

That should do it for the review on the 4-leaf double-eye spring for 3,500-pound trailer axles.

Leafsprings appears to be good. Changing from a 3 leaf spring to a 4 leaf spring but these are lighter in weight. Hoping they will handle the weight on my double 3500 lb axles. Extremely fast shipping. Box was tore up a good bit but it's hard to hurt Leafsprings. Will post again after they are mounted. 597824

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! 355950

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. 557915

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. 554466

I have ordered many items from etrailer an always had excellent customer service. The staff were extremely helpful and knowledgeable. However, this last order did not go so well. I knew immediately when I explained what I needed he was very inexperienced. I was constantly placed on hold when explaining what I needed. I know already he did not send several items I needed and sent the wrong bolts to attach the springs. Now I'll have to go to the local hardware store to find my 5/8 X 3 inch galvanized bolts to mount the springs. Also the shackles I ordered were not in the box and not on the invoice. Whenever I order from E-Trailer again I will research their experienced first. I asked the staff if he knew what he was doing when I was placing the order, I never received a reply. 498041

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.... 480006

Do you have a question about this Trailer Leaf Spring Suspension?


  • Replacement Leaf Spring Recommendation for a 3,500 lb Dexter Axle
  • From 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 # SP-212275 for if you need a 25-1/8 inch spring or # SP-210275 if you need a 27 inch leaf spring.

  • Upgrading Leaf Springs on a Trailer with a 3500 Pound Axle
  • If you are wanting to go to higher capacity leaf springs I would advise against it. The problem is that since the trailer axle is rated for 3,500 pounds you won't gain any additional capacity by switching to higher capacity springs. What it will do is not allow the suspension to compress as much leading to a very stiff and jarring ride for the trailer and anything in it. Another problem is that alternate springs may not have the correct measurements and that would mean that the spring...

  • Torque Specs for U-Bolts with 3,500 Pound 4-Leaf Double-Eye Springs
  • To use with the 4-Leaf Double-Eye Spring for 3,500 Pound Trailer Axles # SP-210275 I recommend the U-Bolt Kit # APUBR-1. The manufacturer doesn't list any specified torque specs for this kit but based on the size of the hardware (1/2 inch diameter nuts) you will want to torque them down to about 70 foot pounds. I have attached an installation video that you can also take a look at.

  • Recommended Leaf Springs for Vintage Trailer
  • The 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 will work with your vintage trailer. It looks from the photo like you would also need the Replacement U-Bolt with Nuts for 2" Wide, Square Trailer Axles - 9/16" Diameter # 175211 and the U-Bolt Plate - 2" Wide, Square Trailer Axle - 1-3/4" Wide Spring - 9/16" Bolts # TRTP200175.

  • Estimated Weight rating for 1-1/2-Inch Square Trailer Axle
  • Trailer 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.

  • Can 4-Leaf Springs be Replaced with 5-Leaf Springs on 2016 Grand Design RV?
  • We can certainly help you replace your leaf springs, but your 2016 Grand Design Reflection 29RS, has Lippert 3,500 LB tandem axles, and unfortunately there are no 5-leaf springs available which meet that capacity. To find proper replacements, you will need to know the length of the springs from the center of one eye to the center of the other eye. If that measurement is 25-1/8 inches, you will want the 4-Leaf Double-Eye, # SP-212275. If the eye-to-eye measurement is 27 inches, you need...

  • How To Determine Trailer Leaf Spring Replacement Based on Axle Capacity and Other Components Used
  • For your replacement leaf spring, there are a few things to consider. The number of springs in the stack doesn't determine the capacity, so you will need to know the capacity of your axle so you don't have springs that are too stiff or not strong enough for your application. For instance, if your springs are for a 3,500 lb axle, then the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 may be the correct replacement even though it is 4 leaf versus 6 because the...

  • Replacement Leaf Springs for Dump Trailer with 3500-lb Axle
  • If 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...

  • Should the Space Between Tandem Axle Trailer Tires Be the Same On Both Sides of the Trailer
  • Is 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...

  • The 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...

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,...

  • Suspension Solution for Trailer with 3,500 lb Axles to Smooth Out Ride Quality
  • Longer 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.

  • What to Consider When Replacing a 3,000 Pound Single Axle Trailers Leaf Springs
  • If you use a higher rated leaf springs on a lower rated trailer they will work but will cause stiffness in your ride quality. This is due to the trailer not being under the heavier weight therefore less flex of the springs, using a higher rated spring will not increase the capacity of the trailer because the trailer itself cannot support more than the stated 3,000lbs of weight. When replacing leaf springs you will want a new u-bolt kit like # APUBR-1, the correct shackle bolt like #...

  • Double Eye Leaf Springs for Boat Trailer, Stretched Out
  • Before you can pick out a set of leaf springs for your boat you need to find out the weight rating of your trailer axle. Then you will need to purchase leaf springs that are each 1/2 of the axle rating. The # SP-210275 is rated for 1500 pounds so if your boat trailer axle is a 3000 pound axle then I would say that # SP-210275 is the correct leaf spring for your axle. Due to wear and different manufacturing tolerances the spring dimensions will be slightly different especially for length...

That is priority one. For example if you were using the springs part # 1020, # SP-219275, # SP-111275, # SP-218275, # SP-115275, or # SP-220275 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...

  • Recommended Replacement Leaf Springs for Ranger Boat Trailer with 3000-lb Axles
  • It is tough to get a correct eye-to-eye measurement on a double-eye leaf spring when the spring is still installed in the suspension. It is much better to measure for a replacement leaf spring by removing it first. Also, if a spring is very old and well-worn it can actually become longer than it was when new. Years of use can cause a leaf spring to elongate by as much as 1/2 to 3/4-inch. In a 1-3/4-inch wide double-eye spring rated for a 3500-lb axle, we offer the 4-leaf # SP-210275...

  • Replacement Leaf Spring Recommendation for a Single Axle Ranger Boat Trailer
  • The way to pick out a leaf spring for a trailer is to go with the one that will match the axle capacity needed and is the correct length. For you the part # SP-212275 is the correct one to use. It is for a 4,800 lb axle (close enough) and has an overall length of 25-1/4 inches. Leaf springs tend to stretch out over time so yours new would have been this exact length most likely. The height of this spring is 3 inches.

  • Vintage Trailer Suspension Replacement Recommendations
  • Going to a higher rated spring will not give you higher rated axles. The axles themselves have their own rating independent of the springs. So going to a higher rated spring would only increase your trailer capacity if they were the weakest link prior to replacement. That being said, your current springs are 28 inches long so you will want to pick out a spring that is slightly shorter than that as springs tend to stretch over time. The part # SP-210275 would be the best candidate as...

We offer one single leaf spring, part # SP-115275, and it is designed for 6,000 axles. It has a measurement of 25-1/4 inches eye center-to-center. If you are measuring the spring after it has been taken off the trailer it may have flattened a bit over time. As far as the leaves in the leaf spring, we may have one...

  • Should Trailer Leaf Springs Have Higher Capacity Than Axles
  • I recommend keeping the springs rated for 7,000 pounds if your trailer's axles are rated for the same. You have to keep in mind that a portion of the trailer's weight (Likely 10 to 15 percent) is on the hitch and therefore the tow vehicle's rear axle and not on the trailer axels. If you use 9,000 pound springs and overrate them you're likely to have a rough, stiff ride. Springs are rated by the axle capacity. The leaf springs for 3,500 pound axles are: # SP-216275 which are 23-1/8...

  • How to Pick Out Leaf Springs for 2000 Fleetwood Toy Hauler SUT26A
  • You will want to measure the distance from eye to eye of your old leaf springs and then pick a leaf spring with the same weight capacity of your trailer axles and is slightly shorter (around 1/2 inch) to compensate for the sag and wear of the old leaf spring. Once you know the length you need check out the chart I attached that has all of the springs we carry. The lengths are in the column A.

  • Leaf Spring Recommendation to Replace 27 inch Long Spring on Camper with 1,500 lb Trailer Weight
  • Length-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 # SP-124275 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...

  • Leaf Spring Replacement Recommendation for a Boat Trailer with a 3000 lb Axle
  • The 4-Leaf Double-Eye Spring # SP-210275 that you referenced that is 27 inches long should work well for you. Typically you want the spring a little bit shorter than the hanger distance (about 1/2 inch) but you're close enough that it should work just fine. I attached an FAQ article on trailer suspension for you to check out also.

  • Availability of Double-Eye Leaf Spring with 30-Inch Eye-to-Eye Measurement
  • The double-eye leaf springs we offer are all 1-3/4-inches wide and are available in lengths from 20-1/4-inches for 2000-lb axles up to 27-inches for 3500-lb axles, part # SP-210275.

  • Availability of 3000-3500lb Leaf Spring With 26-3/4 Inch Length
  • The best way to measure an existing leaf spring is to put the trailer up on jack stands and let the axle hang, then measure the center to center distance between the spring eyes. The closest leaf spring we offer to the 26-3/4 inch measurement you mentioned is the # SP-210275 which has a length of 27 inches. Using two of these springs would provide a capacity of 3100 lbs. Keep in mind that the capacity of the trailer will be limited by the capacity of its lowest rated component, be it the...

  • Torque Spec For Leaf Spring Shackle Bolts
  • There is no specific torque rating for shackle bolts. You'll want to ensure that the bolts you use are long enough so that when installed you will have at least 2 threads protruding from the nut. Make sure that the bolt you're using has a lock nut, like part # 166081. If the bolt you are using has knurls at the bolt head, tighten the bolt down until the knurls go through the shackle link or hanger and the bolt head is flush. Then back off the nut slightly so that all of the components are...

  • How to Pick Leaf Springs for a Trailer
  • If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible. You will want to also measure the distance from eye to eye of your old leaf springs and then pick a leaf spring with the same weight capacity of your trailer axles and that is slightly shorter (around 1 inch) to compensate for the sag and wear of the old leaf spring.
