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.

Installed on Brother's utility trailer that had the original mobile home trailer axles and very stiff single leaf spring. Now the trailer doesn't try to pass him when the road is rough.

Replaced sagging springs on Shasta Compact. Easy installation however these new springs are 1/4 inch thinner than original. Because of this the old u-bolts should be replaced as well. I used 1/4 inch spacers on top of the spring plate because the threads on the u-bolts were rusted and the nuts would not tighten down. Trailer is now level again. 782131

I purchased this set of leaf springs along with a kit to put axle under the leaf springs. I ordered the parts on Monday night around 7:50 pm. Found out I had made a mistake in what I had ordered and called the help line. Stacy got my order changed to the correct parts and I had the order the very next day by 3:00 pm. This is AMAZING to me! Put on the parts Tuesday night without an issue. The old springs were wore out and very bouncy. The new ones are very firm. The conversion went just a painless. After it's all said and done, my utility trailer, which is a converted pop-up camper was raised about 5" or more. No more having to worry about the tires hitting the frame anymore. 776548

Ask the Experts about this Universal Group Trailer Leaf Spring Suspension

  • 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...

  • How to Determine Leaf Spring Hanger Placement on a Single Axle Trailer
    Generally speaking, on a single axle trailer you will want the leaf spring hangers to be spaced apart 1/2" less than the eye to eye measurement of your leaf spring. Therefore, you will want to place the hanger 25-1/2" apart on center when using the 4-Leaf Double-Eye Spring part # SP-124275 with the Single-Axle Trailer Hanger Kit part # APS4. Please keep in mind that you will need to determine the correct position of your Dexter Trailer Axle part # 20545I-EZ-72-15 before welding the leaf...

  • Leaf Spring Recommendation for Ham Travel Trailer with 26 inch Long Springs
    We have a few options for 26 inch long trailer leaf springs but you will need to know the axle capacity you have. I would imagine the best option is going to be the 2,000 axle leaf spring part # SP-124275 since your trailer is most likely pretty small. The next size up is the part # SP-051275 which is for 4,000 lb axles.

  • Recommended 26 Inch Leaf Springs for 1,500 or 2,000 Pound Trailer Axle
    When measuring your existing leaf springs, you will want to measure the length from the center of spring eye to the center of spring eye. If you measured a length of 26 inches, then the 4-Leaf Double-Eye Spring # SP-124275 should be a perfect replacement if you have a 2,000 pound axle. To confirm your axle rating, I recommend checking for a plate somewhere on the axle itself that lists its capacity. Even if you do find that your axle has a 1,500 pound capacity, this leaf spring set...

  • Replacement Trailer Suspension For Single Axle Boat Trailer
    From the looks of the photo you sent it does not look like you have an OEM suspension system on your boat trailer. I recommend securing the suspension rail to the trailer frame in a more secure manner like drilling and using bolts so that it does not shift. If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible. You will...

They both are double eye leaf springs that are 26 inches long but they look like they fall outside of your weight range and they both have 4 leaf springs instead of 3.

  • Recommended Leaf Springs for Continental EC312 Boat Trailer
    The 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 are stronger than the capacity of your trailer, but you will still be limited to the 1200 lb GVWR of the manufacturer. The only thing to be aware of is this could cause a stiffer ride when unloaded. As long as your double eye leaf springs are 26 inches from bolt hole to bolt hole centers, this will work very well for you. I've attached a video to assist.

  • Are Leaf Springs Installed Under the Axle or Over the Axle?
    Trailer leaf springs are traditionally mounted under the axle. To mount them on top of the axle, you need to use an over-under kit to allow you to put spring seats on top of your axle. If you already have the spring seats mounted on top and bottom, then you can choose which orientation you desire based on your desired trailer height but springs will mount only where spring seats are on the axle. If you only have them installed on the bottom, then you will need a kit to allow you to install...

  • Are there Bolt-On Hangers for Trailer Leaf Spring Suspension
    We do have a couple of bolt-on spring hangers # CE14017G and # CE14016G but they are designed for slipper springs and not double-eye springs like # SP-124275. Its not likely that professional welder would charge that much. You might be able to find one locally via an iron workers union near you. For u-bolts for your 1-1/2 inch square axle you can use # SP01-120 for 2 u-bolts and 4 nuts. For a u-bolt plate you can use # 115983. For a hanger kit you could use # APS1. Now what you could...

  • How Is Trailer Weight Capacity Determined and Can It Be Increased By Adding Different Components
    When it comes to any trailer, including your small utility trailer that transports your Kodiak ATV, the trailer's actual weight capacity will be a function of which of its component parts has the lowest weight rating. A trailer's capacity will be limited to that of the lowest-rated part, either the trailer tongue, the frame, the axle, the suspension, the wheels or the tires. It is the classic "weakest link in the chain" situation. If you were able to know for certain that the weakest...

  • What is the Difference Between Double Eye Leaf Springs and Slipper Leaf Springs
    The difference is found in the application. The Slipper Spring styles, like part # SP-179275, are intended for use with more heavy duty applications, while the Double Eye styles, like part # SP-124275 are used to provide a more comfortable ride. The part # SP-124275 that you referenced will be the correct fit if your current leaf springs are 26 inches long from the center of the attachments points (usually known as eye-center-to-eye-center).

  • Locating Replacement Leaf Springs for 1969 Trailer with 26 Double Eye Springs
    The 26" long 4-Leaf Double-Eye Spring # SP-124275 that you were looking at is designed for 2,000 pound axles, meaning that each individual spring stack has a 1,000 pound rating. While this set matches the length of your existing leaf springs it will be slightly under-rated for your trailer that will weigh around 2,200 pounds. The next closest set in capacity that has a 26" eye-to-eye length is the 4,000 pound # SP-051275 (meaning a single stack has a 2,000 pound capacity). This...

    The leaf springs part # SP-124275 are actually exactly what you need. Over time old springs will stretch slightly which is why your older springs are 5/16 inches longer that these. Aside from that these match perfectly, 2k capacity and 1-3/4 inches wide.

    The clips on leaf springs are designed to be forward of the axle due to braking axle wrap (twisting). The straps/clips aren't super strong to prevent this but they're still there. If the strap comes off or the leaves come apart it is time to replace the springs.

  • Should 2,000 lb Leaf Springs be Used to Carry 1,900 lb Boat
    I believe you are referring to the 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles # SP-124275. Since your boat alone weighs in at 1,900 lbs you would want something beefier as the suspension supports the weight of the trailer as well. The best way to choose your leaf springs is to match their weight capacity with that of your trailer axle. For your situation you would likely need the Leaf Spring # SP-051275 instead which has a weight rating of 4,000 lbs. Please be sure...

    A lot of people get hung up on how many layers their leaf springs have but that actually isn't crucial at all. To choose the correct replacement leaf springs for your trailer you simply need to pick one that has a weight capacity that is rated for the same amount of weight as your axle as well as the same length (or slightly shorter) and width of your current leaf springs. Leaf springs can stretch over time but if you have leaf springs that measure 26" center eye to center eye and they...

  • How are Double-Eye Trailer Springs Measured
    There are several measurements involved in our double-eye trailer springs, such as part # SP-124275; however, yes the eye to eye measurement taken on center is the total length that we use and is standard. Keep in mind when measuring old springs to replace them they're going to flatten out so they'll be longer than they were when they were new. Sometimes they'll be up to an inch longer. Your best bet is to use the length measurement as a starting poing and then find a slightly shorter...

It is possible these will work for you (assuming you have 3,500 lb axles) because springs can elongate over time; so if you were measuring your old springs this may have been what happened.
