Features to know about

Smooth Ride Over Rough Roads: 7-Leaf Slipper Design Handles the Bumps

Every mile adds up, and rough pavement can shake a trailer apart if the suspension can’t keep up. This 7-leaf slipper spring flexes to absorb road shock and smooth out the ride. Its multiple leaves work together to reduce bounce and harsh jolts, keeping your trailer level and steady even on uneven ground.

Built to Carry Heavy Loads: 4,000-lb Spring Capacity for 8,000-lb Axles

When you’re hauling serious weight, you need suspension that can handle it. This spring is rated at 4,000 lbs per spring, giving a combined axle capacity of 8,000 lbs. It’s strong enough to give your trailer solid support under load while keeping the suspension movement controlled and predictable.

Reliable Mounting and Fit: 26-5/8"" Long with Hook End and 9/16"" Eye

A solid connection between your axle and frame is key to dependable towing. This spring measures 26-5/8"" from the center of the eye to the end of the hook and is 2"" wide for a snug fit in standard hangers. The front eye includes a nylon bushing with a 9/16"" inner diameter for smooth motion around the suspension bolt, while the hook end slides cleanly into the rear hanger or equalizer.

Tough Steel Construction for Long Service Life

Made from sturdy steel with 3/8""-thick leaves, this spring is built to stand up to years of towing. It resists sagging and helps prevent the wear that can throw off alignment or cause uneven handling. Replacing both springs at the same time keeps the trailer tracking straight and maintains proper axle geometry for consistent performance.

Video Transcript for Review of EMCO Trailer Leaf Springs - 7 Leaf Slipper Spring Hook End 8000 lb Trailer Axle - EM53AJ

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this 7-Leaf Slipper Spring with Hook End for your 8,000-pound Trailer Axle. Now, this slipper leaf spring acts as part of your trailer's suspension system by providing an attachment point for your 8,000-pound trailer axle. It is made of sturdy steel, and it's designed to flex and to absorb road shock, and give you a smooth ride. That's gonna help reduce wear and tear on your trailer, and it's going to ensure a level ride on bumpy and uneven surfaces. Now, as you know, slipper leaf springs attach to hangers that are welded onto your trailer.

The eye of the spring will attach to the front hanger with a suspension bolt, and then the hooked slipper end of the spring will slide into the rear hanger. Now, if you have a tandem or a triple-axle trailer, the slipper end will slide into the equalizer that connects to multiple springs, and the shape of the slipper end of a leaf spring may vary slightly due to differences among trailer manufacturers. Because of this, it is important to check your leaf spring slipper end before purchasing a replacement spring. Now, if you're also in need of hangers, suspension bolts, or equalizers, you can find all that here at etrailer.com. In the eye is a pre-installed nylon bushing.

The eye diameter with the bushing is 9/16 of an inch, and without the bushing, it's one 5/16 of an inch. Again, this is a 7-leaf spring with a leaf thickness of 3/8 of an inch, and it has a spring capacity by itself of 4,000 pounds, but then when it's paired with another one on the opposite side, that's where you're gonna get your 8,000-pound trailer axle capacity. And then the length from the center of the spring eye to the end of the spring right here right before the hook ends is gonna be right at 26 5/8 inches. The width of the spring is two inches. Now, additional dimensions with the diagram are available on this product page if there are some different measurements that you're looking for that I didn't provide for you today.

And to ensure proper alignment and suspension performance, I'm sure you know this, it is important that leaf springs should be always replaced in pairs, so if you pick one or more of these up and you get it installed, we would love to hear back from you regarding your experience with this spring, or with the set of springs that you pick up, and you can share your experience with us by either dropping a comment or leaving a review on this product page letting us know how everything worked out for you. We would love to hear back from you. Well, that's gonna wrap up our look today. I do hope that our brief time together was helpful for you. Again, my name is Andy, thank you for joining me.
