Bumpy roads and long hauls can beat up both your trailer and cargo. This 6-leaf double-eye spring flexes to absorb road shock, keeping the ride smoother and more controlled. With a 3,500-lb spring capacity for 7,000-lb axles, it keeps everything level and reduces wear on your trailer’s frame and components.
Road grime and salt can eat away at suspension parts, but this spring’s sturdy steel construction and powder-coat finish hold up strong against rust. It’s ideal for marine and wet-weather use, keeping your suspension working smoothly season after season without premature corrosion.
Getting a clean fit matters when replacing suspension parts. This spring measures 25-1/4"" from eye to eye and 1-3/4"" wide, with pre-installed nylon bushings for 9/16"" bolts. The setup makes it straightforward to mount using hangers and shackle straps, keeping your suspension geometry right where it should be.
Old, sagging springs can throw your trailer off balance. This double-eye leaf spring restores proper ride height and stability so your trailer tracks steady behind you. The 1/4""-thick leaves work together to distribute weight evenly and keep the trailer level even on uneven ground.

Hi everybody, Andy here with etrailer.com. Let's take a quick look at this six-leaf double-eye spring for your 7,000-pound trailer axle. Now, this double-eye leaf spring acts as part of your trailer suspension system by providing an attachment point for your 7,000-pound trailer axle. This is made from sturdy steel with a powder coat that's going to help resist rust and corrosion. And this is designed to flex to absorb that road shock and give you a smooth ride. It's gonna help reduce wear and tear on your trailer, and it's also going to help ensure a level ride on bumpy and uneven surfaces.
Now, as you probably know, double-eye leaf springs attached to hangers that are welded onto your trailer. One end of the spring will attach directly to the hanger with a suspension bolt, and the other end will attach to shackle straps that are suspended from a hanger. And these straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you happen to have a tandem or a triple axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. If you are in need of hangers, suspension bolts, or equalizers, you can find all that here at etrailer.com.
In the eyes on each end are pre-installed nylon bushings. The eye diameter with the bushing is 9/16 of an inch, without the bushing it's 11/16 of an inch. And again, this is a six-leaf spring and individually it's rated at 3500 pounds. That means if you install a pair one spring on each side of your axle, you're gonna be covered for 7,000 pounds of trailer weight support. To ensure proper axle alignment and suspension performance, the leaf spring should always be replaced in pairs and we do recommend installation by a professional.
I do wanna give you the measurement of the length, and where I'm gonna be measuring center of eye to center of eye. So as I hope you can see, we're sitting right at 25 and a quarter inches and the width of the spring, one and three quarters inches. Do you happen to have a question, whether it's about this spring or any of the other items that we carry here at etrailer.com, don't hesitate to reach back out to us. We do wanna make sure that you're getting exactly what you want and need. Well again, my name is Andy.
Thank you for joining me.

Hey Tom, I definitely understand how frustrating that can be, having to fight with the bushings and bolts during install is never a good time. The way the spring eyelets are formed at the factory can sometimes cause the hole to be slightly oblong, which can make getting everything lined up more difficult than expected.
