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-220275 Review

Today, we're going to take a look at the 3-Leaf Double-Eye Spring for 4,000 pound trailer axles. Now, this spring is designed to flex to absorb road shock, provide a nice smooth ride, help reduce wear and tear on your trailer. It'll ensure a nice, level ride on bumpy and uneven surfaces. Now, it does mount to your trailer frame with hangers in our hanger kit, which we do sell separately on our website. They are a lot of times listed on the product page as a related product. This does include the nylon bushings right here in the eyes.

Few specs on this, the spring capacity on this is 2,000 pounds. It is designed for axles of 4,000 pounds, so when this is matched with one on the other side, it would meet the 4,000 pound maximum. This is for a quantity of one spring. Again, it has 3 leafs, 1, 2, 3. I do want to give you some measurements on this, the spring length from the center of this eye to this eye is going to be right at 25 1/4 inches. The spring width, I'm going to turn this so I'll measure the width, is going to be right at 1 3/4 inches.

Then the diameter of the spring eyes is a 9/16 of an inch measurement. Now, one note I do want to mention that to ensure proper axle alignment and good suspension performance, you should replace your leaf spring always in pairs. That should do it for the review on the 3-Leaf Double-Eye Spring for 4,000 pound trailer axles.

I bought 4 of these to replace the deformed springs on our 2013 travel trailer that were damaged in a frightening traffic incident in June. I opted for these 2,000 lb. springs versus the 1,750 lb. OEM replacement units since the fit was equivalent and I wanted to ensure sufficient sustained clearance inside the wheel wells. I had no difficulty removing the nylon bushings and installing the bronze ones from the upgraded Dexter suspension kit which I also purchased, and the springs fit perfectly. I'd have given them 5 stars, but they weren't individually boxed so they each suffered some scuffing during shipment which has already resulted in a few premature rust spots appearing. 581394

My boat trailer is 25 years old. I was not really having a problem but decided to replace the leaf springs on the trailer. My order for replacement parts was sent exceptionally quickly. And I installed them the next day. All the parts fit perfectly and everything was sized right. I really enjoyed installing the new leaf springs and parts. The price for the parts seemed very reasonable and the salesman I spoke with seemed very knowledgeable and answered all my questions. 488942

I can't believe it's been a year since I replaced the leaf springs on my boat trailer. I am still amazed at the ride! Every time I look in the mirror when going over the speed bumps between my house and trailer, I wonder why I didn't replace the springs before. It's not something you think about often and I only replaced mine because of the rust but you really need to pay attention to those springs. I won't buy my trailering supplies anywhere but eTrailer.com. Their helpful customer service, fast shipping, and great prices make it well worthwhile to buy from them. 346936

I was recommended this drop hitch by an etrailer employee (to use with a trailer that I completely refurbished, with parts almost exclusively from etrailer.com), and have been using it for a year now. It has been absolutely fantastic, and just what I needed. I am always confident that I'm using a quality product to tow my trailer with, which is imperative when my fur babies are along for the ride! My only complaint, is that the hitch does not come with a square cap to prevent water from sitting within the tubing of the hitch - it's cheap and not hard to find, but would be nice to accompany the hitch at the time of purchase. 337874

This is my second order from etrailer because I measured wrong on the first one. So I got to experience their return policy as well. The web site has great information, they have lots to choose from, quality products, shipping was real fast, and prices are very good. The most important thing is when things go wrong and you need customer service. I have to say they are there to help, my return went very easy with no questions. Customer service is what makes the difference. 327169

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


  • 25-1/4 inch Long Trailer Leaf Spring Recommendation for 4,000 lb Axle
  • I attached a page that has all of the double eye springs we carry that are 25-1/4 inches long from eye to eye. For a spring with the same capacity as the one that you referenced the part # SP-220275 would be what you need.
    view full answer...

  • Selecting Replacement Leaf Springs for Enclosed Trailer
  • Leaf springs stretch with use and age and to make sure you match their length, as well as their capacity, you will want to pull one out of the trailer's suspension so you can measure its eye-to-eye length. A well-used spring can stretch as much as 1/2-inch from its original length. If your hanger hole spacing is 25-inches on center then you may well need a 25-1/4-inch like # SP-220275 but the length of your shackles comes into play too. The spring eye dimension should be longer than...

  • How to Determine Correct Replacement Double-Eye Leaf Springs for EZ-Loader Boat Trailer
  • It is tough to determine the actual length of a double-eye leaf spring when it is still installed in the boat trailer's suspension; it is tougher still if the weight of the boat is on the suspension. In fact, when a leaf spring is old and well-worn, it can actually stretch or elongate slightly, meaning that if you pulled it completely out of the suspension and measured its eye-to-eye length the measurement you get could actually be longer than when that spring was brand new! We are usually...

  • Availability of 25-1/4 inch Long Leaf Springs with Width of 1-3/4 inches
  • We carry a few leaf springs that are 1-3/4 inches wide and have a length between the eyes of 25-1/4 inches. You will want to go with the spring that matches the capacity needed for your trailer. The part # SP-220275 has a 2,000 lb capacity. The part # SP-218275 has a 2,500 lb capacity. The part # SP-111275 has a 3,000 lb capacity. Each of the spring capacity's is rated per spring. With a pair of springs the axle capacity would be double.

  • 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, # 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...

  • Should Leaf Spring Capacity Match Trailer Weight or Axle Weight for Best Ride Comfort
  • You are indeed right to think this way. When picking out the appropriate leaf springs for your custom built trailer you will want to choose them based on what the actual loaded weight of the trailer will be. Just make sure that the leaf springs have a combined weight capacity that matches or exceeds (within reason) the 1,200 pound max weight of your trailer. Matching the leaf springs to the 5,000 pound axle you plan on using will give you an awfully rough ride with a 1,200 pound trailer....

  • 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...

  • Recommended Leaf Springs and Equalizers for Triple Axle Trailer With Double Eye Springs
  • I saw you were looking at double eye leaf springs so we will assume that is what you have. In regards to leaf spring hanger spacing, the most common for a triple axle trailer is 29-1/2" first to second (center to center), 34" second to third (center to center), and 29-1/2" third to last (center to center). Therefore, it would be best if you would place the leaf spring hangers accordingly. Once the leaf spring hangers are in the above positions then you have a few options based on axle...

  • Thank you for your email answering my questions on your axle. I have the information to help you with your tandem axle application. Your current axle is not a standard size, so I recommend replacing your current axle as well. There are two routes to go for this, the more traditional style or the axle-less.

  • Can 4,000 lb Axle Leaf Springs be Used on a 3,500 lb Axle for a
  • Yes, you could use leaf springs for a 4,000 lb axle, like part # SP-220275 (rated for 2,000 lbs each), with a 3,500 lb axle but it will make your ride a bit more stiff. The only times that a leaf spring would become damaged is if it is overloaded or has a defect from the manufacturer. Since overloading a trailer is actually a pretty common occurrence I recommend checking to make sure that you are within the weight capacity of your trailer. It is also important to note that even if you...

  • Hanger Spacing for Tandem Trailer with 25-1/4 inch Leaf Springs and 7-3/4 inch Equalizers
  • For a tandem axle trailer using 25-1/4-inch double-eye springs like # SP-220275 and a 7-3/4-inch equalizer like # TREQE1 the hanger spacing should be approximately 29-1/2-inches. This is a starting point and you may need to adjust this dimension slightly.

  • Double Eye Leaf Springs 25-1/4 Inches long by 1-3/4 Inches Wide
  • For your leaf springs on a 2,000 lb axle, you only need 1000 lb springs x 2 as you stated. With the dimensions you gave, we only have 2000 lb capacity springs currently available. They are the 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 25-1/4" Long # SP-220275. As I stated these are twice as strong a spring as you need, so it will give you a more rigid trailer ride but will fit your hangers and your axle. If you choose to use these springs, you will not increase the weight...
