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 SP-111275 Review

Today we're going to take a look at the 5 leaf double eye spring for 6,000 pound axles. Now this is made of a nice strong durable steel construction. It is designed to flex to absorb road shock, provide a nice smooth ride which will help reduce wear and tear on your trailer. It does ensure a nice level ride on bumpy and uneven surfaces and it does mount to your trailer frame with hangers or a hanger kit which we do sell separately on our website and lots of times we'll list them on this product page as a related product. If you notice in the eyes themselves it does include the nylon bushing. A few specs on this, the spring capacity of this one spring is 3,000 pounds so when this one is matched with one on the other side of the axle, it will give you a total .. It will meet the actual capacity of 6,000 pounds.

Again, if you notice it is 5 leafs, 1, 2, 3, 4, 5. I'll give you a few measurements on this. We're going to do the spring length and width which are the critical measurements. The spring length will be measured from the center of this eye to the center of this eye. If we take the tape measure, you can see if we go right across it will be 25 and a quarter inches for the spring length. The spring width will be measured edge to edge just right there, so you can see it's right at 1 and 3 quarter inches for the width and the eye diameter on the double eye, the eyes right here is 9, 16, 7 inch.

Now this part is for quantity of one spring. One last note I do want to mention that to ensure proper axle alignment and suspension performance, leaf spring should always be replaced in pairs. That should do it for the review on the 5 leaf double eye spring for 6,000 pound trailer axles.

I just wanted to let you know what a GREAT experience it has been ordering from your company. I have never had a company check up or keep me as informed on what was happening with my order. It is a great relief to know that there are still some companies that care and are not just interested in "a sale." I have attached some pictures of the old springs I took off and the new one's. The old ones were stretched flat with my dump trailer empty. When I put the new ones on it even raised the trailer up at least 4 inches. 29072

Product was great. arrived early. But it was the wrong size, greatly in part, my fault. I measured the lenght of the leafs instead of the lenght from eye to eye center. Wish during the ordering processes it was explained on how to measure. I have looked at wheels and wheel bolt patern and the instructions for ordering the correct bolt patern there are great. I am sure its probably common knowledge with those that deal with leafs on a regular basis but for those of us that will order this only maybe once in a life time, measuring instructions would have been greatly appreciated. Loved how customer service was always in contact and still is after delivery. 26134

I ordered new springs (PR5), hanger kit (APT5), and u-bolt kit (APUBR-1) for the worn out suspension on my 16 year old flatbed car trailer that has mainly been misused as a hay trailer. Whenever I receive boxes containing pieces/parts I immediately inventory to make sure everything is there. It was. It all went together as it should and I've just taken it for a test drive over some rough roads. It tows like a new one even though it sure doesn't look like it. I recommend all of these products purchased as a group because of (seemingly) good quality, proper fit, and popular prices. 191982

I recently bought Dexter E-Z Flex equalizers and was told by multiple forum members, "Since you're unbolting your leaf springs anyways it's cheap insurance to replace your 4 leaf springs with 5 leaf springs" After much online research I found etrailer had the best price when you took advantage of their free shipping special. I could not be happier with their service and FAST shipping!!! 142844

I just finished installing the leaf springs on my triple axel boat trailer and I'm very satisfied with the result. Shipping was quicker than anticipated… One suggestion is having a complete hardware kit that is galvanized for salt water boat trailers. i.e Shackles, equalizer, and bolts with nylon lock nuts. Thanks again for a Great Product! 38691

As described, but a heavy part like a leaf spring should be better packaged for shipping. The springs banged together all the way to California arriving with many paint chips and scratches. I doubt any of this would affect the performance but if you want a fresh new appearance they will need to be repainted when you get them. 182993

The leaf springs and U bolts were of good quality (what can you say about leaf springs). The only problem was insufficient capture and cushioning in the shipping container. I realize 4 springs are heavy but these busted completely through the box and luckily UPS kept the springs and box together. 133548

Received my order right on schedule. The box was much larger than the items but packaged ok. I think a smaller box would work better as all the weight was in the bottom of the box. I haven't installed them yet so I can't review the product itself but appears it will work as designed. 139928

  • Hanger Spacing Dimensions for Installing Double-Eye Leaf Springs on a Trailer
  • The Trailer Leaf Spring, 2250 lbs. 6 Leaf, item # SP-256275, is sold as a replacement spring for older trailers and measures 26 inches for eye to eye, center to center. If you are replacing the springs and hangers you will need to use the same center to center dimension as the original mounting brackets. These springs are designed for a 4,500 pound axle. If you are building a new trailer you will need to determine the weight capacity of the axle you will be using and order springs and...

  • Recommended Hanger Spacing For 4-Leaf Springs on Tandem Axle Trailer
  • You mention that you have a tandem axle with 3 inch axles. A 3 inch axle has a weight capacity rating of 6,000 lbs to 7,200 lbs. The leaf springs for that axle would be the part # SP-111275. These springs have a weight capacity of 3,000 lbs and are designed for 6,000-lb axles. The # SP-218274 (PR4) springs you have mentioned show a weight capacity of 2,500 lbs. So two of the # SP-218275 springs are designed for 5,000-lb axles. I would recommend to check the weight capacity of your...

  • What is the Minimum Space Between Tires on a Tandem Axle Trailer
  • I checked with Dexter, manufacturer of many trailer parts, and according to them there should be at least 1 inch of space between the tires when under load. So once your trailer is loaded and ready to tow, if you have more than 1 inch of space between the tires then going to the larger size would work. You also have to consider the additional width of the larger tire and the additional height. the new larger size will be 3.2 inches taller and 1.25 inches wider than your existing tire...

  • Measurements Needed When Replacing Leaf Springs On Trailer
  • Knowing the exact length of a double-eye spring can be tough, especially if the spring is still on the trailer. The best way to measure them is to remove it from the trailer and measure center-of-eye-to-center-of-eye. If the springs have been on the trailer for a long period of time they can stretch by up to 3/4 inches. The eye-to-eye measurement for part # SP-111275 is 25-1/4 inches. The spring capacity is 3,000-lbs and is designed for an axle up to 6,000-lbs. You mentioned that the...

  • Can Springs Be Upgraded on 5th Wheel Trailer With 5,200-Lb Axles
  • You may go up to a higher weight capacity spring as long as the eye-to-eye length and the width will fit, but the higher capacity springs WILL NOT increase the weight capacity of your trailer. The weight capacity will still be limited to whatever the lowest rated component of the system is, whether it be the axle, the shackles or the equalizer. If you decide to go with the higher-rated springs, you will be making the axle and the spindles the lowest-rated component, which can cause failure...

  • How Much Clearance Should be Between Tires and Fenders on Unloaded Trailer
  • It all depends on how much the suspension travels but I would say unloaded you would want at least an inch from the tops of the tires to the bottom of the fenders. Keep in mind though that over time the springs will flatten out some, as much as half an inch, so keep that in mind years down the road. You could also add some suspension enhancement, # TTRA1032, rated for 7,000 pounds, which will help with support and ride quality. And it will prolong the life of the suspension. For a tandem...

  • Based on my research, your Dexter leaf spring is a double-eye leaf spring with a 3,000 pound capacity for your 6,000 pound axle. The original length of your existing springs is 25-1/4 inches. As springs tend to stretch a bit over time, your existing spring likely measures between 25-1/4 inches - 26 inches. To replace the springs on your axle, you can use the # SP-111275 leaf spring.

  • The minimum distance between front and rear tires on a tandem axle trailer is 1 inch (when under load). If you are at 1 inch now and the trailer is not loaded then you would need to move at least one axle. This means that you would have to cut off hangers and have them welded back on in a new location by a professional welder. Spring # SP-111275 is indeed longer than # SP-198275 by 3/8 of an inch. If you went with shorter springs and longer equalizers then you could get more space between...

  • Can I Replace 4 Leaf Springs With 5 Leaf Springs For The Axle On My Trailer
  • Yes, you can replace your 4 Leaf Springs like part # SP-221275 with 5 Leaf Springs like part # SP-111275 as long as you replace all of the springs at the same time. There really isn't any advantage if you want to go with 5 leaf springs over 4 leaf springs. Typically, you always want to try to get the same parts to replace what you already have, but 1/8 of an inch difference per leaf spring won't make much of a difference in how everything fits together. The 5 leaf springs will work just...

  • Upgrading Leaf Springs On Trailer For 3000 lbs Capacity On 3500 lbs Axles
  • You can absolutely upgrade your 4-Leaf Double-Eye Spring for 5,000-lb Trailer Axles - 25-1/4" Long, # SP-218275, to the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long, # SP-111275. This upgrade will give you the 3000 lb capacity you mentioned, but it will not give you the ability to carry larger loads. Your load capacity is rated by your axles themselves, so although stronger springs will make things less squatty, it will basically just give you a firmer ride on your...

  • 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...

  • 6k Trailer Axle Leaf Spring and Tandem Axle Hanger Kit Recommendation
  • The leaf spring part # SP-111275 is designed for 6k axles. On a tandem axle trailer with these springs you would end up with a 12k capacity. If your axles really are 6k rated these would be the ideal springs to use. The recommended hanger kit to use with this spring is the # APT5 because all of the hangers are the same size and you end up with great tire clearance. The equalizers that come with this are 7-3/4 inches. The distance between the axles will end up being 33-1/2 inches and...

  • Replacement Leaf Spring Needed for 5th Wheel with 6,000 Pound Axles
  • The replacement leaf spring that I have available to fit your 6,000 pound axle is the 5-Leaf Double-Eye Spring, # SP-111275. This spring measures 25-1/4 inches long by 1-3/4 inches wide. In order to ensure proper traction and a safe, level ride, we recommend that all leaf springs be replaced at the same time and that all springs match. By using the # SP-111275, you would be replacing a 4-leaf spring with a 5-leaf spring so it is strongly advised that all springs be replaced. Please...

  • How to Pick Out Replacement Leaf Springs for a R-Vision Trail Lite Crossover
  • You gave me a lot of great information, but the last piece of the puzzle is the axle capacity of your trailer. With that I can tell you what spring would work best. Priority number one for picking out leaf springs is to go with the proper rated spring. I tried looking up your trailer info but could not determine the axle capacities. If you check the plate or plaque up near the coupler of your trailer you will see the axle ratings listed there. You will want to then check out the link...

  • 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.

  • Is there a Specific Amount of Clearance Required Between a Tire Sidewall and the Trailer Frame/Body
  • If you keep the trailer tires inflated to the maximum psi indicated on the tire sidewall then they should not bow out on the sides enough to cause any clearance problems between the tire and the trailer. A 1/2 inch space could be enough but it is situational. It might be enough on some trailers while others may need more space to prevent rubbing. Going with a narrower wheel and/or skinnier tire could be all you need to have better clearance.

  • Will Trailer Leaf Springs with Taller Spring Stack Raise the Height of a Trailer
  • If the springs on your trailer are also 14 years old then they have probably flattened out a bit and that could have lead to the tires rubbing the fenders more so than switching to a larger tire size. Going with new springs will certainly help. If the # SP-111275 spring has the right measurements and capacity then it will work well and provide ample clearance between the tires and fenders.

  • Recommended Replacement Leaf Springs for 2005 Keystone Raptor D3612 Fifth Wheel
  • Trailer manufacturers typically don't list the specific leaf spring specs in their product information but I did call Keystone to see if they could provide the necessary details about your 2005 Raptor D3612 fifth wheel, such as axle capacity, spring length, etc. My contact there was not able to provide this. What you can do is check on the axle's safety sticker or I.D. plate for its rated capacity. You can also observe how many leaves there are in the springs. The other things you need...

  • How to Select Replacement Leaf Springs for 5th Wheel Trailer
  • It does sound like you have found some clear damage to your 5th wheel trailer's leaf springs that will require attention. Uneven tire wear can be caused by a number of things - incorrect pressure, inadequate weight on the axle or a visibly damaged component like a leaf spring that has allowed the suspension geometry to change. It sounds like the broken driver-side spring is letting the axle hang too low on that side, which brings the tire's outside edge into more contact with the road...

  • Leaf Spring Recommendation for 5k Axle that is 25-1/4 inches in Length
  • Since you need at least a 5k rated spring that is 25-1/4 inches in length (like the # PR4) you would actually want the part # PR5 which is a 6k rated spring. A little more capacity than needed is better than a little less so this would be your best option. We don't currently have any 5k rated 3 inch axles so you would need to contact a local trailer shop in your area who can custom order you in an axle to the specs you need.

  • Hanger Kit Recommendation for a 6K Axle on a Tandem Trailer
  • There are two spring options that would work for you, the part # SP-115275 that you referenced or the 5 Leaf Spring part # SP-111275. The only difference is that the # SP-111275 is a multi-leaf spring with a 100 lbs more capacity than the # SP-115275. Either would work fine for you, I would go with the # SP-111275 just because of the additional capacity, and with a multi-leaf spring if a leaf fails your trailer wouldn't be completely un-usable. You would be able to limp home to fix the...

  • 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...

  • Determining the Correct Leaf Springs for a 1996 Interstate Trailer with 5200 lb Axles
  • The 5-Leaf Double-Eye Spring, # SP-111275, will work with a hanger spacing of 29-3/4 inches. The typical hanger spacing for a 25-1/4 inch long double-eye leaf spring is 29-1/2 inches when using the 2-5/8 inch long shackle straps, # 115052. The extra 1/4 inch of the hanger spacing will not affect the performance. The best way to determine which leaf springs you need is to compare them to the original leaf springs. Overtime, leaf springs will flatten making them longer than their original...

  • Does Single-Leaf 6K Leaf Spring SP-115275 Have a Pilot Nub for U-Bolt Plate
  • The Universal Group 1-Leaf Double-Eye Spring # SP-115275 does not have a center bolt as found on the comparably-rated 6K spring # SP-111275. That center bolt head, or pilot, is not present on the single leaf spring because it is not needed as it is with multi-leaf springs. You can still install this spring using a u-bolt plate that has a center hole. Although these two springs share the same dimensions and weight capacity (25-1/4 x 1-3/4, and 6K) if you are replacing a multi-leaf spring...

  • How Much Clearance is Needed to Account for Suspension Travel on a Trailer
