Features to know about

Smooth Towing Over Rough Roads: 4-Leaf Slipper Spring Handles 2,000-lb Axles

Bumpy roads can jar your trailer and wear down suspension parts fast. This 4-leaf slipper spring flexes to absorb road shock and keep your trailer riding smoothly. Each spring has a 1,000-lb capacity, making a pair ideal for 2,000-lb axles. The multiple 1/4"" thick steel leaves share the load evenly, cutting down on bounce and helping preserve other suspension components over time.

Built to Last: Powder-Coated Steel Resists Corrosion

Moisture, road salt, and grime can eat away at suspension parts. This spring’s powder coat finish helps resist the elements and prevents corrosion, keeping it looking solid after years on the road. The sturdy steel build maintains its shape and strength so you can count on consistent ride performance.

Reliable Fit and Function: 24-1/4"" Long for Secure Alignment

Proper length and geometry keep your trailer tracking true. This spring measures 24-1/4"" long from the center of the 9/16""-diameter eye to the end of the radius-style slipper. That radius end slides into the rear hanger or equalizer, while the front eye bolts securely to the hanger on the frame. Matching both sides with new springs ensures even axle alignment and stable towing.

Ready for Easy Setup: Includes Nylon Bushing for Smooth Movement

A smooth interface between bolt and spring eye means less wear and squeak. The included nylon bushing is pre-installed in the 9/16"" eye, giving the spring quiet, friction-free movement right out of the box. It’s designed to work with standard hangers and hardware (sold separately), making replacement or new installation straightforward for most DIY setups.

Video Transcript for Review of EMCO Trailer Leaf Springs - 4 Leaf Slipper Spring Radius End 2000 LBS Axle - EM48AJ

Hi, everybody, Andy here with etrailer. Let's take a quick look at this 4-Leaf Slipper Spring with Radius End for your 2,000-pound Trailer Axle. Now, this slipper leaf spring is a key part of your trailer suspension system. This is designed to support a 2,000-pound trailer axle to help deliver a smoother, more stable ride. It's flexible steel, so it's going to absorb road shock. It's gonna help reduce wear and tear on your trailer, while keeping it level over bumps and uneven terrain.

Now, this does include a nylon bushing with a 9/16 of an inch inner diameter. And you're going to need either pre-mounted hangers or an aftermarket hanger kit, which is obviously sold separately from the spring, to complete the installation. The spring's eye is going to connect to a hanger mounted on your trailer frame, while the slipper end is going to slide into a rear hanger or equalizer. This is built from durable steel, and this spring is gonna be tough enough to handle the road ahead. You are going to get this one leaf spring.

The individual capacity of the spring is 1,000 pounds, so paired with another spring on the other end of your trailer, that's where you're gonna get your 2,000-pound axle rating. And let me see if I can give you some measurements here. Try to make it as clear as I can. So I'm gonna be measuring from the center of the eye all the way to the end of the spring. So it looks like we're sitting right at 24 1/4 inches long from center of eye to the end of the spring.

And the width of the spring is 1 3/4 inches. The diameter of the eye without the bushing is gonna be 11/16 of an inch. Again, with the bushing, it's 9/16 of an inch. The bushing's included. The leaf thickness is 1/4 of an inch.

And again, you're gonna get four leaves here in the spring. And of course, to ensure proper axle alignment and suspension performance, leaf spring should always be replaced in pairs, and we do recommend insulation by a professional. If you happen to have any other questions, whether it's about this spring or anything else that we carry here at etrailer, don't hesitate to reach out to us. We wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.

The leaf springs came in quickly and appear to be good quality. The only thing I wish was different was I needed the bolt holding the leaf's together to have the nut on the bottom, and the round pin on top, so I could mount the axle above the springs. It still fit over the nut, but I think the round pin end would be more durable than the nut when rubbing the edges of the axle hole over time.

See what our Experts say about this EMCO Trailer Leaf Springs

  • Are Leaf Springs Corrosion Resistant
    Hi Clarence; leaf springs like the # EM48AJ you referenced and the # e39SR you ordered have a powder coat finish. This will resist the basic elements and help prevent corrosion. We also have leaf springs like the etrailer Rust-Resistant 6-Leaf Slipper Spring # e46FV which come with a Dacromet finish with a salt spray rating of 700 hours ideal for applications like your boat trailer.

  • Replacement 22-1/4" Long Slipper Spring for Boat Trailer
    Hey Larry, thanks for reaching out! The 4-Leaf Slipper Spring w/ Radius End for 2,000-lb Trailer Axles # EM48AJ is the closest match we have for you, and this measures 24-1/4" long altogether. If you check out the linked dimensional photo though, you'll see the top of that curved part at the end to the eyelet on the other end measures 22-11/16" which is closer to what you're needing. Does this look like it will work out for you?

  • Replacement 22-1/4" Long Slipper Spring for a Utility Trailer
    Hey Jack. You'll want to take a look at your leaf springs when the trailer's unloaded compared to when it's loaded down. If those springs are flatting out quite a bit it's definitely time to replace them. Especially if your trailer is squatting when loaded down. How old is your trailer and how long are your leaf springs from the center of the mounting hole to the curved part with the weight off of the suspension? I attached a diagram below. The measurement needed to determine replacement...
