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-256275 Review

Today we're going to take a look at the 6-Leaf Double Eye Spring for forty-five hundred pound trailer axles. Now this a strong, durable steel construction. This spring is designed to flex to absorb road shock and provide a nice, smooth ride. Helps reduce wear and tear on your trailer, helps ensure a nice level ride on bumpy and uneven surfaces. Does mount to the trailer frame with hangers or a hanger kit, which we do sell separately on our website. If you notice in the eyes themselves, it does include the nylon bushing. A few specs on this, the spring capacity on this spring is two thousand, two hundred and fifty pounds.

Now when this one's paired with one on the other side of the axle, it'll meet your axle capacity of forty-five hundred pounds. This does have six leaves, as you can see. One. Two. Three.

Four. Five. Six. Now this spring length which will be measured from the center of this eye to the center of that eye, if you take a tape measure, center to center, you can see is twenty-six inches. Spring width, turn it that way, and the width of this is going to be right at one and three quarter inches. The diameter on the eye, the inside diameter is nine sixteenths of an inch. This is for a quantity of one spring.

Now one last note I do want to mention on this, is to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs. That should do it for the review on the 6-Leaf Double Eye Spring for forty-five hundred pound trailer axles.

I ordered leaf springs and associated attachment hardware. I was quite amazed at how quickly the order was delivered even though the box weighed close to a hundred pounds. The order was complete and error free. The trailer was much improved by the installation and I look forward to using it. I have used etrailer.com in the past and it's my first internet stop for trailer parts. 156972

The springs arrived quickly and are the proper fit. The packing materials were insufficient, however. By the time the springs arrived they were bursting out of the box.

Prompt shipment and arrival. It was a few days before I installed one. The old ones which are probably original equipment ( it's a 1975 trailer) were a real pain to get off, but the new one was a perfect fit. I did the right side since it was broken, then took the trailer out and it worked fine. I am still getting the left side off, but I'm sure that the new one will be fine. 322552

I actually ordered these for 65 Coronet Altered Wheelbase car for the front end using an A-100 straight axle. The short 13" dimension from the center bolt to the spring eye makes this perfect for my application. Mixing trailer with car spring attachments was a challenge but doable. Enclosed are pictures of how it was mocked up with a relocation of 12" forward from stock. I wasn't able to use the U bolts as they were a different dimension and diameter than the existing A-100 axle. Using the front bolts with the Zerk fitting will be an added advantage being greasable. 232715

This is the second item I have order from E Trailer and I have had great results on both items. 139720

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


  • Correct Leaf Spring for Trailer with Lippert 3,500 lb Axle
  • Thank you for the photo! I was able to use the serial number on your axle to determine which is the correct replacement leaf spring for your trailer. For this, you are going to want to use the 3-Leaf Double-Eye Spring part # SP-220275 which is a double eye leaf spring that is 1-3/4" wide, has a 4,000 lb total weight capacity, and a 25-1/4" eye to eye measurement. The measurement you provided of 26" long is correct but the leaf spring needs to be measured while unloaded as it will lengthen...

  • Replacement 26 Inch Leaf Springs, Shackle Straps, And U-Bolts
  • To give you the correct leaf springs, I would need to know the capacity of your axle or what your Gross Vehicle Weight Rating (GVWR) is not just the weight of the trailer itself. This is the loaded capacity of the trailer. We have a few options for 26 inch leaf springs: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # SP-051275 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long...

  • Recommended Leaf Springs for 4,400 lb Axle Based on Axle Position and Hanger Locations
  • The typical springs for the AL-KO 4,400 axles are one of two lengths. If you have the 25-1/4 inch length, then you will want the 4-Leaf Double-Eye Spring for 5,000-lb Trailer Axles # SP-218275, but if you have the 26 inch springs, you will want the 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles # SP-256275. The width will be the same so you will want to determine the length based on the position of the axle using dimension A and D in the attached photos and the axle position based...

  • Will Shackle Straps Help Improve Trailer Ride
  • Yes, using shackle straps will help improve the ride of your trailer, though not as much as getting the properly rated leaf springs, which you are already doing. Shackle straps will help because they are the link between your springs and what I assume is the hanger on a single axle boat trailer, and will allow a bit of movement in the system, helping minimize the rigidity in your trailer's ride. For a single axle trailer, shackle straps are generally 3-1/8" long (measured from center...

  • How to Determine the Correct Replacement Double-Eye Trailer Leaf Spring for a Boat Trailer
  • A trailer leaf spring will wear out over time and the wear will likely lengthen the spring. Therefore, the correct replacement leaf spring will likely be shorter than the leaf spring you have on your trailer now depending on the amount of wear that has occured. If the leaf springs you have on your trailer now are 26-1/2" long from the center of each eyelet, I recommend using a 26" long leaf spring like part # SP-124275 for 2,000 lb, part # SP-051275 for 4,000 lbs, part # SP-256275...

  • Can Heavier Leaf Springs Be Substituted to Offset Weight of Multiple 5th Wheel Slide-Outs
  • Your concern with uneven tire wear and suspension sag from the weight of your toy hauler's 4 slide-outs can be addressed by installing stiffer springs on that one side of the trailer. I confirmed with my technical contact at Grand Design that this is permissible and that other owners have done the same. You will want to select springs of the appropriate eye-to-eye length to match your OEM springs and of a weight rating that is not too much higher than the OEM springs. My contact recommended...

Check out the picture I attached that shows them. The 4,500 lb leaf spring you'd then want is the part # SP-256275 which measures 26 inches in length. If you have a different length let me know and I'll see what would be the best solution. Looking at your picture the shackle straps and bolts seem to be in decent shape but for...

  • Installation of Hanger Brackets and Springs for Tandem Trailer Axles
  • It is not uncommon for the trailer hangers on a tandem axle trailer to be all the same size or for there to be different sizes that can be 1-1/2 to 2 inches different in height when you compare the center hanger to the front and rear. For example, the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs - 2-1/2" Front/Rear, 4-1/2" Center # APT8 has that 2 inch difference in size. I've attached an article on suspension to help further as well. You will want to make sure you position...

  • Your Aristocrat's axle may have a sticker or tag indicating its weight capacity, or you can use the Lo-Liner 13's listed dry weight of 1300-lbs as a guide. This dry weight suggests it has a 2K axle which would use 26-inch 4-leaf springs # SP-124275. Your best bet for selecting new leaf springs for your vintage Aristocrat is to remove one completely so you can measure its eye-to-eye length without it being under load.

  • Replacement Leaf Spring Options for 3,500 Pound Trailer Axles
  • To determine the correct replacement spring you will need to go by the measurements of the existing springs. This is best done with the weight off of the spring you are measuring either by removing it or by jacking up one side of the trailer. We have replacements that are rated for 3,500 pound axles. All of the springs on the trailer should be replaced at the same time so that the trailer doesn't have some good springs and some worn out ones. That could lead to poor ride quality and...

  • Replacement Leaf Springs, Equalizers, and U-bolts for ALKO T52 Axles
  • Those may not be the original springs on your Springdale. According to ALKO the T52 axle would either have a 5 or 6 leaf spring at a length of 26 inches. To be accurate the springs should be measured with no weight on them because they will otherwise flatten out some leading to a longer measurement. ALKO shows the 4-leaf spring for the T52 at a length of 25-1/4 inches. If you measure it at about 25-1/4 inches with no weight on the spring then you can use # SP-218275 for 5K axles. If...

  • If the measurements on your trailer match the 4-Leaf Double-Eye Spring, part # SP-212275 or part # SP-218275, they will bolt up to your trailer. My contact at Redline informed me that the heavier 4-Leaf Double-Eye Spring, part # SP-218275 will work, but it will give you a rougher ride. Also the weakest link on the trailer will be the 3,500 lb axles when using the 4,800 lb leaf springs. It is recommended to use the Leaf Springs For 3,500 lb Axles, part # SP-212275 for your trailer...

  • 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 Trailer Suspension Shackle Face Up and Down
  • Sounds like one of your shackles is facing the wrong direction after installing everything. When a shackle flips around and faces the wrong direction on trailer suspension most of the time just putting weight on the trailer and driving will correct the problem. Or you can try jacking up one of the axles to get the equalizer to angle and allow the shackle to flip around.

The hanger kit you most likely have is the part # APT6SE.

  • Axle Placement for Making a Boat Trailer
  • What you will want to do to start is the 60/40 split, or 60 percent of the length to the front of the axle and 40 percent behind it. You will also need to determine the trailer's weight and the tongue weight of the trailer, which will be easier to do if you have a mock up of your trailer. I have added a photo with an equation on it that will guide you in the process so you can get the axle in the right spot for your 24 foot pontoon.

  • Spring Hanger Spacing for 26 inch Long Leaf Springs and Availability of Shorter 6k Springs
  • You will want to remove your spring hangers and then weld them in a position that allows the shackles to hang properly. On a spring that is 26 inches eye to eye on center and a single axle trailer you will want the hangers to be up to 1/2 inch less than the spring length so 25-1/2 inches on center between the front and rear hangers. We have two 6k axle leaf springs available that are shorter than 26 inches long. We have the part # SP-111275 which measures 25-1/4 inches and the part...

  • How to Measure a Trailer Leaf Spring
  • To measure for the correct leaf spring length, you should jack up the trailer so that the axle hangs free, then measure straight across from the center of one eye to the center of the other eye.

Each of our product pages for the leaf springs shows a diagram showing the width and height of the spring. If you click the provided links, you can see the double eye leaf springs we offer as...

  • How to Choose Replacement Leaf Springs for Boat Trailer
  • You will probably not need to move your spring hangers to install new leaf springs. What happens when a spring is well-worn is that it will become longer, by as much as 3/4-inch. To pick out your new leaf springs you will want to remove one completely so that there is no tension on it; then measure its eye-to-eye dimension and select a new spring based on that and the axle weight rating. Also keep in mind that the shackle straps that connect the springs to the hangers are available in...

  • Replacing Leaf Spring Recommendation for a 2004 Weekend Warrior Super Lite FK 2100
  • Since you have dual axles you will split the overall capacity of your trailer between the two axles. So you would not want a double eye leaf spring set for 8,000 lbs even if we made one because that would be way overkill for your setup. The closest spring sets that we offer would be the 4-Leaf Double-Eye Spring # SP-218275. This spring has an axle capacity of 4,800 lbs, so when you double that because of your dual axle setup you end up with a capacity of 9,600 lbs which is more than...

  • Spring Hanger Position for Tandem Axle Trailer with 6000 lb Axles
  • To determine the location for the axles on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger. The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger. For example, if the trailers frames length is 18 feet, then the center-line location for the equalizer...
