Features to know about

Smooth Ride Over Rough Roads: 3-Leaf Slipper Spring Flexes to Absorb Shock

Bumpy roads can put a lot of strain on your trailer and cargo. This 3-Leaf Slipper Spring with a radius end flexes under load to resist shock and smooth out the ride. With its 24-5/8" length and 1-3/4" width, it’s built for a 1,500-lb axle and carries up to 750 lbs per spring. The multi-leaf design spreads the load evenly, cutting down harsh jolts and reducing wear on your trailer frame and mounts.

Consistent Suspension Support: Sturdy Steel Handles Everyday Use

When you’re hauling gear day after day, you want a spring that holds up. This slipper spring is made from sturdy steel that stands up to repeated flexing and heavy loads without sagging. Its 1/4" thick leaves maintain proper height and alignment so your trailer stays level even on uneven ground. Replace both springs at the same time for balanced suspension and proper axle alignment.

Reliable Mounting and Smooth Movement: 9/16" Nylon-Bushed Eye for Secure Fit

The front eye of the spring includes a nylon bushing with a 9/16" inner diameter, giving you a snug fit around the suspension bolt and quiet, low-friction movement. The slipper end slides easily into the rear hanger or equalizer, keeping the spring aligned as it flexes. That simple, durable setup keeps your axle tracking straight and your trailer rolling smoothly.

Straightforward Replacement and Setup: Works with Standard Hanger Kits

This spring installs easily with pre-mounted or aftermarket hanger kits (sold separately). The design matches standard 1-3/4" wide slipper spring hangers, so whether you’re refreshing a worn suspension or building from scratch, it fits cleanly into place. The result is a dependable suspension setup that rides smooth and stays solid mile after mile.

Was supposed to do the job tomorrow and now need to call the customer and cancel. Had to cancel the first job today because of wrong parts. I am LOOSING MONEY on my end. NOT HAPPY.

Upgraded the leaf springs to tote my HD Glide down to the border for the Winter trip to Mexico. Easy swap out. I really don't know if it was necessary but I don't want to be that guy on the side of the highway with a disabled trailer. So yes I made and will go again this year.

  • Replacement 3-Leaf Slipper Springs and Bushings for 1,200 lb Trailer
    Hey Dave, thanks for reaching out! It looks like our 24-5/8" Long 3-Leaf Slipper Spring # e99SR is going to be the best replacement for your setup. This comes with a nylon bushing (which is standard) in that eyelet, so you actually won't need to get a whole new bushing either. I do recommend checking on the weight rating though. This spring is designed for axles up to 1,500 lbs and while your overall weight rating is near that range, we do want to make sure you aren't over or under loading...

  • Replacing 24-1/4" Slipper Springs On A 4x6 Carry On Trailer
    Hello JT, thanks for reaching out. Yes, the 24-5/8" long 3-Leaf Slipper Spring # e99SR will indeed work to replace your 24-1/4" long springs. When replacing leaf springs there is a small amount of tolerance, and a 3/8" difference is not going to throw off your suspension or anything. Just keep in mind these springs are for a 1,500 lb axle and each spring is rated for 750 lbs so please just be aware of this and make sure your don't overload the springs.

  • 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!

  • Does etrailer Carry 26" Long Hook End Leaf Springs
    Hey Dennis thanks for all that info! I checked what we have, and it looks like for our hook end springs, the closest we have to what you measured is the Dexter 4-Leaf Slipper Spring w/ Hook End for 2,500 lb Trailer Axles # DX93QR. This spring is 26 3/4" long for that "C" measurement, so it's going to be a bit longer than what you have which isn't going to work since springs typically lengthen an additional 3/4" over time. We do have 26" long springs, but they are double eye and not the...

  • How Much Distance Should I Have Between The Tire And The Trailer Frame?
    I can certainly point you in the right direction. I will start by saying that our "rule of thumb" is that we want at least 1" of clearance between the tire and the trailer frame. With the hub face currently at 48", you will want to go with an axle that is at least 50" hub face, if not a bit longer. 54" would be acceptable, but we would not want to go longer than that.   Unfortunately, we do not offer any axles that will be close to this size. Our shortest round tube axle is 60" hub face....

  • Replacement Slipper Spring For a Boat Trailer With 4-Leaf Spring 25.5" Long
    The closest size we have to a 25.5" slipper spring is 24-5/8". Do understand that this may be the correct size for your application since as leaf springs sag and get flatter they also get longer in length. Also the amount of leaves a spring uses does not always account for the weight they can carry so be sure to check your boat trailers axle capacity and match it to the correct springs. 2-Leaf Slipper Spring w/ Radius End for 1,000-lb Trailer Axles # e36SR 3-Leaf Slipper Spring w/ Radius...

  • How to Verify The 3-Leaf Slipper Spring # e99SR Will Replace the Spring on the Trailer.
    To verify the 3-Leaf Slipper Spring # e99SR will fit your trailer you will need to take the weight off your current leaf spring so you can compare it with the measurements. Please see the image below to know where to measure and know the lengths A, B and F could be different depending on how much the spring sags. This leaf spring is 1-3/4" wide. A: 11" B: 22-3/4" C: 24-5/8" D: 12" E: 14-1/2" F: 4" If you find your measurements are different please let me know what you find so I can...

  • Does Trailer Need to be Jacked Up to Measure Leaf Spring for Replacement
    Jacking up the trailer frame to get the load off of the leaf spring is needed to get accurate dimension of spring for replacement. It would seem unlikely that your spring would be 24.5 inches if when there's a load it's 26 inch but you never really know. You will also need to know the axle capacity of your trailer as well.

  • Is There Difference in Quality Between 1,500 lb 3-Leaf Slipper Spring e99SR & SP-178275
    There really is not any type of quality difference between the two slipper springs: - 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # e99SR & # SP-178275 They both have the same measurements, steel construction, and nylon bushing in the spring eye. I'd honestly go with the least expensive option to save yourself some money. Also, I do recommend new bolts when mounting springs, the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079.

  • Can I Replace Leaf Springs With Lower Rating For Better Ride Quality
    Yes, you can swap from the 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # e99SR to the 2-Leaf Slipper Spring w/ Radius End for 1,000-lb Trailer Axles - 24-5/8" Long # e36SR to help reduce how much shock is being transferred to your trailer frame. My only caution going this route is to make sure you don't overload the leaf springs since you're reducing their weight rating. Attached is a review video for you to check out.

  • Should Leaf Springs on Trailer Sit Totally Level
    Ideally the leaf springs sit as level as possible. If they are going to angle at all you would want the front maybe a little higher than the rear but perfectly level is the most ideal. I would recommend using the mounting holes that allow it to sit totally level.

  • Does 3-Leaf Slipper Spring w/ Radius End Require a Bushing for Rear of Spring
    For the 3-Leaf Slipper Spring w/ Radius End # e99SR you only need the bushing on the one end, the other end will either sit over a bolt or will fit into a hanger like part # 115706S. If you have a double-eye spring on your trailer then you'll need something like the 25-1/8" Long 3-Leaf Double-Eye Spring # e66SR instead. Attached are some videos for you to check out as well.

  • Availability of a Slipper Spring with Radius End and 1,500LB Axle Capacity With a Length of 26"
    The only 1-3/4" wide slipper spring we are going to have with a radius end rated for 1,500lbs is the 3-Leaf Slipper Spring # e99SR you found. If you cannot find the correct size you may have to move your Hanger # CE14017G to use these shorter springs.

  • Quantity Included On The 3-Leaf Slipper Spring with Radius End # e99SR
    The 3-Leaf Slipper Spring w/ Radius End # e99SR comes with one single spring. You will have to purchase two to complete the axle. This spring has a measurement of 24-5/8 inches from center of spring eye to center of spring eye. The spring is for a 1,500 pound axle capacity. It has a sturdy steel construction and the nylon bushings are included. I attached a review video link below.
