Features to know about

Smooth, Level Ride on Rough Roads: 4-Leaf Slipper Spring Handles Shock and Bumps

When your suspension takes a beating from rough pavement or washboard roads, this 4-leaf slipper spring smooths things out. Each of its four steel leaves flexes to absorb shock, reducing bounce and sway for a steadier, quieter ride. With a spring capacity of 2,150 lbs and an axle capacity of 4,300 lbs, it keeps your setup level and your gear from jarring loose on uneven ground.

Reliable Strength for Heavy Loads: Sturdy 1-3/4" Wide Steel Construction

A dependable suspension starts with solid steel. This spring is built from tough steel and measures 1-3/4" wide, giving it the strength to hold up under constant use and heavy hauling. The 3/8"-thick leaves keep their shape and performance even after thousands of miles, helping prevent sag and uneven wear in the suspension.

Easy Fit and Alignment: 26-1/4" Long with 9/16" Nylon-Bushed Eye

Getting the right fit makes all the difference in how your suspension performs. This spring measures 26-1/4" from the center of the eye to the center of the open end when unloaded, ensuring proper axle alignment and smooth articulation. The front eye includes a 9/16"-inner-diameter nylon bushing already installed, so it’s ready to mount to the hanger with the correct suspension bolt and hardware.

Simple Replacement and Maintenance: Works with Standard Hangers and Equalizers

Whether you’re swapping out worn springs or fabricating a new setup, installation is straightforward. The open-eye end slides into a rear hanger or equalizer, while the front eye mounts to a welded frame hanger. Hangers, bolts, and other hardware can be purchased separately to match your setup. For best results and even alignment, replace both springs at the same time—this ensures balanced load support and consistent handling.

  • Is The etrailer 4-Leaf Slipper Spring e24SR Measured Under Load?
    Hi Geoffrey! The length of the etrailer 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles - 26-1/4" Long # e24SR is indeed taken when there is no load on it. When you measure your springs, you will also want to be under no load at all (we typically say it's best to jack up the trailer by the frame when measuring the leaf springs). As to your question about how this is measured, it is from center eye to center eye (or at least where the center of the eye would be on a slipper...

  • Determining If Open Eyed Slipper Leaf Spring Is Needing Replaced
    Your trailer uses an open eye leaf spring like # e24SR. Over time as the leaf spring softens the gap you are seeing will get bigger. As long as the leaf spring is not falling off the hanger when you raise the trailer weight off the axle they do not need replaced unless visibly damaged. Since the overall length of the spring changes as the spring wears I recommend measuring the length of your spring on the radius of the spring(see image). Since this measurement remains the same it ensures...

  • Can Radius End Leaf Springs Be Used to Replace Hook End Leaf Springs
    Hey Caleb, unfortunately you can't use slipper springs with a radius end like the 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles # e99SR because the brackets are different. You could use open eye springs like # e24SR to replace your hook end springs but I'd recommend making sure the new open eye springs have the same load capacity and dimensions as the old hook end springs. If there is something else I can do to help you, please feel free to let me know in the comments below!

  • Replacement Hangers Needed For 1-3/4" Wide Open-Eye Slipper Springs
    Hey Jack, Are you referring to the hangers that your slipper springs mount to? If so, you'll want to measure the height of your current hanger to make sure you're either getting the same size or larger to avoid any clearance issues. For example, we offer the # APS3SE, which comes with 1-1/2" tall front hangers and clip-style rear hangers to match up with the open-eye end of your springs. Let me know what your height is and I'd be happy to find the correct fit for you.

  • Can Trailer with 3,500 lb Axles Use 4,300 lb Axle Leaf Springs
    Hey Mike, yes you can for sure replace what you have now with the 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles # e24SR that you referenced since you said the dimensions all match. This would be a slightly higher rated spring so in theory the ride quality would be a little stiffer but I don't think you'll feel or notice a difference. Especially if your trailer weighs closer to 3,500 lbs. If your trailer is superlight weigh and already over sprung then it would make it...

  • Do You Have The Replacement Open Eye Leaf Springs and Hardware For a 2001 Load Rite Boat Trailer
    The only open eye 1-3/4" wide leaf springs we currently carry is the etrailer # e24SR & # e33SR. I have no way to verify the weight capacity for your current springs but as it is only a 2" square axle this spring is likely much heavier than you will need. We do have the U-Bolt Kit # CE23103 for your axle which includes 4 u-bolts, 2 plates and 8 washers and nuts. Then you will need 2 of the Hanger Bolts # TRFA73Z916DLNZ for the leaf springs.

  • How Tight Should The Shackle Bolts And Nuts Be Tightened?
    Hello Paul, great question. The shackle bolts cannot be tightened too much. There is no torque rating for these bolts because tightening them too much can cause the suspension to bind up. The nuts are to be tightened until the knurled portion of the bolt pulls completely into the shackle strap and the bolt head is ran all the way down to the shackle strap and you have at least 2 threads extending past the face of the nut.

  • Should Open Eye Slipper Spring Be Replaced When Flattened and Touching Frame
    Hi Alan; you definitely want to replace those leaf springs. If they have flattened out that means they're worn out and ready to be replaced anyway. Rubbing on the frame like that could also cause other problems. New springs will keep it from pushing up into there since they will have their arch back, pulling the open end down where it should be. Our open eye slipper spring selection only consists of the 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles - 26-1/4" Long #...

  • How to Determine Correct Replacement Slipper Springs
    In order to find the correct replacement slipper spring you will need the length, width, and the capacity. The leaf count does not indicate capacity and is not important when determining a replacement. This information would also make a difference in the mounting hardware. For example, the 4-Leaf Slipper Spring w/ Open Eye End # e24SR is 27" long, 1-3/4" wide, and designed for 4,300 lb axles. Assuming a single axle, you could use the # APS3SE and # APUBR-1 (this is for a 2-3/8" diameter...

  • Replacement Bushing For 4-Leaf Slipper Spring e24SR
    There is indeed a replacement bushing for the 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles - 27" Long # e24SR; the correct part is the following: - Nylon Bushing # TRBU11566

  • ShoreLand'r Boat Trailer Slipper End Leaf Spring Rubbing On Trailer Frame
    On a slipper spring with a flat end like you have it is normal for the end of the spring to rub on the frame/spring hanger. With the style mount you have it makes me think you original springs were Open Ended # e24SR. This would help to explain the sleeve you have on the bolt as well as the spring would have rolled on the sleeve. The original spring was likely damaged and since they probably were not able to find the correct size they just went with what they could make work.

  • 27 Inch Slipper Spring For A 4,300 Pound Trailer Axle
    We do not have a direct 27 inch slipper spring but depending on how old your springs are they could have flattened out a bit. The 4-Leaf Slipper Spring w/ Open Eye End for 4,300-pound Trailer Axles # e24SR has a spring capacity of 2,150 pounds and has an axle capacity of 4,300 pounds. The length of the spring is 27 inches and has a spring with of 1-3/4 inches. It has 4 leaves. If you could let me know the weight capacity of your axle I will be able to see if this will work for you. I...

  • Recommended Winch for a 1986 ski Nautique 2001 Boat and DHL Trailer
    For your 1986 ski Nautique 2001, I recommend the Dutton-Lainson Hand Winch item # DL15440. It looks like your boat weighs 2,400 lbs dry and is almost 19' long so this 2-speed 3,200 lbs winch would work perfect. I'm not sure if you're using carpeted bunks or roller bunks but the item # DL15440 has plenty of capacity to work with both. You'll also need the Hand Winch Strap with Safety Hook, 2" Wide x 20' Long - 4,000 lbs. item # DL24242. We do not have a complete rubber bumper assembly....

  • Recommendation For Slipper Springs That Are 29 Inches Long And 1-3/4 Inches Wide
    Unfortunately, I do not have an exact match in our available inventory. Often springs flatten and become longer as they get older. If this has happened with your springs then they are longer than when first installed. What I do have that is close and that might work is a 4-Leaf Slipper Spring w/Open Eye End that is 26-1/4 inches long, Item # e24SR. It is 1-3/4 inches wide and designed for 4,300-lbs axle. Because your total length is 29-1/2 inches and the bolt to spring measures 13...
