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-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 could not be happier with their service and FAST shipping!!! 142844

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

We broke two springs on our 5th wheel so I found a good spot to stay and ordered the springs and all other parts from E trailer. Getting the old springs and related hardware off was a nightmare, but I managed. Putting the new springs and other hardware on was easy. I received great help from several of the videos at etrailer.com. I did replace all 4 springs and all other suspension hardware that wasn't welded on. Now the camper sits up about 4 inches higher, rides much better and is much more stable going down the highway. I feel much safer now, and need to since wife and I are full time Rvers. Did I mention that the prices were great? 567837

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 broke one of my four leaf leaf springs and this was an upgrade, good quality and easy to install. Only thing I didn't like was the shipping box, the springs came out of it somewhere in shipping and we're scratched up. Should have replaced my old ones years ago. My trailer sits a little taller maybe a 1\2 inch. Love them. Fit perfectly. I have other trailers and will buy again. Can't believe the local shops want more than double for the same capacity spring. 374480

Wanted to switch to five leaf springs from 4 leaf on my dual axle 27 ft. trailer. Prices were better than I could get in Calif. with addition of free shipping. Parts arrived in three business days, I was surprised at promptness. Staff very helpful after I got my measurements figured out, as old springs were stretched 3/8 inch. Shocks arrived just after I had the springs all installed. Parts were great, only thing I would have liked better was a small instruction sheet on torqueing bolts. Would recommend etrailer to my friends. 401268

My large camper flattened the factory springs so decided to upgrade them. I went from a four leaf 2500 lbs. spring to a five leaf 3000 lbs. spring. With the addition of a 4 inch equalizer between the two springs to make them horizontal, I finished the job in about 5 hours (including jacking up the camper and supporting it). On a 1/2 hour road test to verify repairs, I immediately noticed a big difference in ride and handling. I am so glad I did this. etrailer was great to deal with also from pictures and comments to items offered. They answered my questions promptly and shipping was a breeze. 704582

We installed these for a utility golf cart after not being able to find any heavy duty springs for the application we needed and these worked great. Make sure to measure your U-Bolts if you are going from a 2 or 3 leaf because these will sit a bit taller. Very good quality product, measurements for the springs are accurate. 694566

  • Leaf Spring Hits Equalizer After New Leaf Spring Install
    The most common mistake when replacing a trailer leaf spring is measuring the existing leaf spring while the trailer is loaded (wheels on the ground) and not accounting for the leaf spring lengthening over time. Therefore, it sounds like the new leaf spring you have may be a bit longer than the one it replaced which is why it is now hitting the equalizer. This would be the only reason that this happened if the equalizers and shackle straps remained the same. If you still have the old...

  • Replacement Double Eye Leaf Spring For 6,000 Pound Axle on 5th Wheel Trailer
    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. This double-eye spring has a matching length, 25-1/4 inches, and weight capacity, 3,000 pounds, to your...

  • 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...

    To replace the 6,000lb leaf springs on your 2014 Grand Design 337, a great option is the Double-Eye 5-Leaf Springs, # SP-111275. These are 25-1/4 inches long, so to confirm they will fit your trailer, it is best to try and measure your current, unloaded leaf springs to assure proper replacement length. Typically, the number of leaves on a suspension system will not have an affect on the setup, especially when looking at leaf springs within the same weight capacity. The difference in the...

  • 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...

  • 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.

  • Recommended Replacement Leaf Springs For Fifth Wheel Trailer
    You do want to measure the springs with the weight off of them because they will flatten out with the weight added. Over time, springs can flatten a bit and that is why you are getting the 26 inch measurement. Based on the measurements you provided, I recommend going with part # SP-111275. This is a 5-leaf spring and is designed for 6,000-lb axles. You also want to check the rest of your suspension to make sure everything is in good working order.

  • Spring Hanger Placement for Single-Axle Trailer Using 25-1/2-Inch Double Eye Springs
    The hanger spacing for a single-axle leaf spring setup will be slightly greater than the distance between the leaf spring's two eyes. Please refer to the linked image to see how the spring and shackle are oriented in this type of setup. The shackle strap length has some effect on the spacing but for a spring with eye-to-eye spacing of 25-1/2-inches your two hanger holes should be approximately 25-3/4-inches to 26-inches. Be sure to measure the spring when it is NOT installed and under tension.

  • 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...

  • 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.

  • Potential Causes for Sagging Leaf Spring on Passenger Side of 5th Wheel Trailer with Slideouts
    It is generally always best to replace trailer suspension components on both sides of a trailer. This can reduce the chance of tracking problems that can occur if the suspension characteristics are not symmetrical. If the springs on the curb side of your 5th wheel routinely wear/sag faster than those on the left side, and if this is where your largest slide is, then you may simply have a case of faster wear from that weight. Trailer loading naturally also affects wear and tear on the suspension. Moving...

  • 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...

    You will be fine, I spoke with one of our installers here and he said that the springs will have small length variances due to one spring having more of a bow shape when compared to the other springs but once weight is put on the trailer after installation everything will even out as the springs all have the same spring rate.

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...

    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.

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...

    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...

    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.

    On a leaf spring the metal band that wraps around the bundle of steel leaves is intended to remain in place after installation. If your trailer's leaf springs now have hose clamps installed around them this could indicate that at one time the springs were over-loaded and that band was forced off or broken.
