Double-Eye Spring

Part NumberABCD

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.

Today, we are going to be taking a look at the 3-leaf double-eye spring for 2,500 pound trailer axles. It's made from a nice, steel construction. Very strong, durable design. Now, these we're designed to flex. That way it absorbs road shock and it's going to provide an overall smoother ride. It's also designed to reduce wear and tear on the trailer.

Now, this is going to ensure a nice, level ride on bumpy and uneven surfaces. It mounts to the trailer frame with hangers or a hanger kit. Those items are sold separately. If you are in need of hangers or a hanger kit, you can find them right here at The nylon bushings in the eyes are included. Pre-installed, already in there.

This is going to contain 3 leaves. It's going to offer a spring capacity of 1,250 pounds. It's designed for 2,500 trailer axles. Now, a few measurements to go over with you real quick. The most important one's going to be the spring length. Now, the spring length is taken from the center of one eye to the center of the other.

If we place a ruler on there and do that measurement, that's going to give us a measurement of 25 1/8 inches. The spring width, that's just measuring from edge to edge, that's going to measure 1 3/4 of an inch. Then, the eye diameter is 9/16 of an inch. Now, to ensure proper axle alignment and suspension performance, please keep in mind that leaf springs should always be replaced in pairs. That's going to do it for today's look at the 3-leaf double-eye spring for 2,500 pound trailer axles.

Once again, etrailer was fantastic. Their website had all the information I needed. Before last week I had no idea what a leaf spring system was, all I knew was that whatever that thing was on the bottom of my camper was snapped in two and I needed to fix it. Did some research on, it walked me through how to take the measurements and what I needed to look for. I took the measurements and found the product that fit my camper. As I always do, I shopped around, and once again, etrailers price was the best by far. I placed the order on a Friday morning and received a very nice email that afternoon from etrailer thanking me for being a repeat customer and notifying me they had expedited the shipping of my products and they left the warehouse that same day. Showed up on my porch the following Wednesday. Amazing customer service! I ordered the leaf springs, ubolts, shackles and shackle bots needed to replace the springs on both sides of my camper. When I opened the box, everything I ordered was in there and looking great. They shipped exactly what I needed, when I needed it at a price that couldn't be matched anywhere. Everything looks great, haven't had a chance to get them on the road yet, but I'm sure it will be top notch when I do. Thanks again etrailer! 97447

Delivery was very prompt sooner than expected. The information your site provided was spot on. I was able to find a more durable tire for a trailer we are pushing the tire limits. And increase the spring rating by only 500lb fisrt time I've seen off the shelf springs offered in such finite sizes. Though we load within the limits of our trailers this particular unit is at the top of the load range. The slightly heavier parts give me confidents we'll get where we want to go. Thanks we'll be calling again. 65079

Thanks to, I was able to find out that this is the right spring for my trailer. Where before, my trailer was dangerously bouncy, now it rides as smooth as it should. Also thanks to etrailer's video, I knew exactly how to install it. It was very straightforward, and although it took some elbow grease, it wasn't too difficult in the end. Spring works perfectly, just what I needed. 29717

Ask the Experts about this Universal Group Trailer Suspension
Do you have a question about this Trailer Suspension?

  • 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...

  • Dimensions for Spring Hanger Spacing Using the # APTT3 Triple-Axle Hanger Kit on a Boat Trailer
  • The spring hanger mounting dimensions for the Triple-Axle Trailer Hanger Kit, item # APTT3, are as follows. From the center of the hole in the front hanger, to the center of the hole in the center front hanger, the distance should be 29-1/2 inches. From the center of the hole in the center front hanger, to the center of the hole in the center rear hanger, the distance should be 34 inches. And from the center of the hole in the center rear hanger, to the center of the hole in the rear...

  • 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 # SP-219275. Each spring has a capacity of 1,250 pounds. If a new hanger kit is needed you can use # APS1. When used with spring SP-219275 the center to center...

  • Trailer Leaf springs # PR4B 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 # SP-212275. 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 25-1/4 inches these would be the correct...

  • 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...

  • 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 # SP-219275 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...

  • Would Switching to a Leaf Spring with a Lower Weight Capacity Improve Ride of Boat Trailer
  • Swapping out your 3500 lb leaf springs for the 2500 lb springs would improve your ride, IF (and only if) the weight of the boat, trailer, motor, gasoline, cooler, tackle boxes, more coolers, fishing poles and other gear stowed on it will not exceed the 2500 lb capacity of the springs. If the capacity is exceeded, you will actually experience a rougher ride as the trailer will bottom out. What is your axle rated for? If at all possible, you want to match the spring capacity to the capacity...

  • What is the Correct Distance Between the Spring Hangers When Using a SP-219275 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 to Pick Out Leaf Springs for a Venture Model VBT Trailer that has 26 inch Long Springs
  • Dimensionally we have several double eye leaf springs that will work, but you will need to know the axle capacity of your trailer so that you pick out the correct rated spring. If you have 2,500 axles you would want part # SP-219275, 3,500 axles part # SP-220275, 4,800 lb axles part# SP-212275, 6,000 lb axles part # SP-111275. You'll notice that all of these springs are 25-1/4 inches long. Springs tend to stretch out over time and that is why yours measured a bit longer at 26 inches.

  • How Can I Determine The Weight Capacity Of the Leaf Springs on a 1996 Mobile Scout RFK-30 5th Wheel
  • To determine the capacity leaf springs you have on your 1996 Mobile Scout RFK-30 fifth-wheel trailer you should look on the frame of your trailer for a plate that will have the VIN number, there should also be a listing for the axle ratings too. You can also tell the weight capacity of the axle by measuring the diameter of the axle. A 3,500-lb. axle will have a diameter of 2-3/8 inches and a 6,000-lb. to 7,200-lb. axle will have a diameter of 3 inches. I am sending a link to an FAQ page...

  • 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.

  • 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 # SP219275 that you referenced would be a great 2,500 lb leaf spring.

  • How Much Space Should be Between the Top of the Axles and the Bottom of a Boat Trailer
  • Normally when using hanger kit # AP233-H248 with spring # SP-219275 the distance from the bottom of the frame to the center of the axles is going to be approximately 4-1/2 inches. Subtract half the width of the frame then to the top of the axles that would be 3-5/16 inches. Two inches might work out fine depending on how far the suspension travels but more height would likely be needed considering the heavier load. Hanger kit # APT4 would provide more height since it has taller hangers...

  • Recommended Springs and Ubolt Kit for 1993 Tacker Trailstar Boat Trailer
  • Sounds like the 3-Leaf Double-Eye Springs # SP-219275 are what you are looking for. They have an eye to eye distance of 25-1/4 inches, a width of 1-3/4 inches and are rated for 2,500lb trailer axles. The ubolt kit # APUBR-10 should provide you with enough clearance. This ubolt kit is designed for 1-3/4 inch round axles and are 4-1/4 inches long and the ubolt post has a diameter of 3/8 of an inch. See the picture I've attached.

  • Determining the Leaf Spring Drop From an Empty Trailer to a Fully Loaded Trailer
  • The drop that you will experience with the 3-Leaf Double-Eye Spring for 2,500-lb Axles, # SP-219275, from a trailer at zero load to full load is going to be 1-1/2 inches. A few things to note with a fully loaded trailer is that you will want at least 3 inches of clearance above your tires and 2 to 2-1/2 inches of clearance from the top of your axle to the bottom of the frame where the leaf spring hangers are welded. You will also want to get the correct hanger kit for the leaf springs...

  • 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 # SP-219275 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.

  • How to Determine Axle Capacity to Pick Out Leaf Springs
  • Can you measure the diameter of the axle? That will be a great way to get a ball park on the axle capacity. Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb Axles: 3-1/2 inch diameter - 9,000-lb Axles: 4 inch diameter - 10,000-lb Or more axles: 5 inch diameter Most likely the leaf spring part # SP-221275 would be what you would...

  • Trailer Leaf Spring Recommendations for a Boat Trailer with 1,900 Pound Boat
  • The leaf springs should be rated to match the axle on the trailer. Spring # SP-256275 is rated for 2,250 pounds per spring so it fits 4,500 pound axles. These springs would be overkill for a boat weighing up to 1,900 pounds and it would be a very stiff and jarring ride for your boat. Your trailer axle may have a capacity listed on it somewhere and if not then there should be some capacity information on a placard or sticker near the front of the trailer somewhere. Whatever the gross...

  • 2,500 lb Axle Trailer Leaf Spring Recommendation
  • For a 2,500 lb leaf spring we have the part # SP-219275 that would work well. This spring is 25-1/4 inches long. For u-bolts we have a few different sizes depending on the size of your axles. What you will need to do is measure the diameter of your axles and then check out the link I attached that has all of the U-bolts we offer. You will need to select the size you have from the filters on the page.

  • Can Trailer Leaf Springs Lose Their Weight Capacity Over Time
  • Springs can wear out over time and lose ability to support the same amount of weight they once were capable of. It sounds like you are in need of a new set of springs on your trailer. You will need to determine what weight capacity springs you will need. The same plate that told you what tire size was recommended for the trailer should also have the axle capacity. The amount of springs doesn't necessarily indicate the capacity of the spring. If you need a 2,500 lb axle spring you would...

  • Replacement Leaf Spring Recommendation for a 2008 Interstate Enclosed Trailer
  • Yes, I would strongly recommend you replace all four at the same time. We always recommend they all get replaced at the same time to be safe. Since your trailer capacity is 7,000 lbs and your worn out springs are 26 inches long the correct replacement spring for you would be the Redline Spring part # SP-220275. Four of these will have 7,000 lbs of capacity and they are 25-1/4 inches long so they will match up perfectly for you. Springs tend to flatten out over time and get longer, so...

  • Replacement Leaf Springs for a Boat Trailer Rated for 3,740 Pounds Gross Trailer Weight
  • The double-eye spring we have that is closest to the measurements you have provided is # SP-256275.

  • 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 # SP-219275 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.

  • Thickness of Trailer Leaf Springs SP-210275 and SP-219275
  • I went and grabbed a # SP-219275 from our warehouse and measured the thickness of the leafs of the spring where it would attach to an axle and found that it measures exactly 1 inch thick. The distance from the center of the spring eyes to the bottom of the spring measures 3 inches and this spring has the standard 1-1/2 inches of deflection. The thickness of the leaf spring # SP-210275 is 3/4 inches. The distance from the center of the spring eyes to the bottom of the spring measures...

  • How to Determine if a 108 Triple Axle Fender Would Work with the Hanger Kit part # APTT5
  • The distance between the axle centers with the # APTT5 when used with a 25-1/4 inch spring like the # SP-219275 will be 34 inches. You would need to compare that dimension to the dimension of the wheel centers on the fender to see if this kit would fit. Tire size will play into this as well. You will need to consider this also.
