Rough pavement and uneven surfaces can make a trailer bounce and rattle. This 4-leaf double-eye spring flexes to absorb shock and smooth out the ride. Each spring carries 2,500 lbs, giving a total axle capacity of 5,000 lbs. The 25-1/4"" length and 1-3/4"" width keep the suspension tracking straight while reducing wear and tear from vibration.
A dependable suspension starts with strong materials. This spring is built from durable steel for long-term strength and consistent performance. It comes fitted with nylon bushings and 9/16"" eyes for a snug, quiet connection that helps cut down on metal-to-metal noise. The 3/8""-thick leaves provide firm support without giving up the flex that keeps the trailer stable.
When springs sag or stretch over time, trailer alignment suffers. Replacing both sides with fresh, equal-length 25-1/4"" springs restores balance and keeps the trailer level. That even stance protects tires and suspension components while improving how the trailer tracks behind a tow vehicle.
Installation is simple with standard double-eye suspension parts. One end of the spring mounts to a welded hanger on the frame, and the other connects to shackle straps or an equalizer. The 9/16"" eye diameter matches common suspension bolts, making it easy to bolt up with existing or replacement hardware.
This spring is designed to take the punishment of long trips and heavy loads. Its steel construction and multi-leaf design let it flex under pressure without losing integrity. Whether replacing worn factory parts or refreshing a high-mileage setup, this spring restores the firm, steady ride you expect from a well-tuned suspension.

Hello everybody, this is Jeff at etrailer.com. Today I'm gonna take a look at this 25 and a quarter inch long 4-Leaf Double-Eye Spring for 5,000 pound trailer axles. Now this leaf spring act as part of your trailer suspension system, provides the attachment point for your trailer's axle. This is for a quantity of one leaf spring. The number of leaves is four. The spring capacity on this spring is 2,500 pounds.
So when this is used with one on the other side, it'll meet the axle capacity of 5,000 pounds. Now the multiple leaves here allow flexibility to absorb road shock, allows for a nice smooth ride, reduces wear and tear on your trailer, and it'll ensure a level ride on bumpy and uneven surfaces. It is a sturdy steel construction. In the eyes, they do include the nylon bushings already installed. Now the premounted hangers or the aftermarket hangar kit is required for installation.
Those items we do sell separately on our website. Basically this spring will attach to a hanger mounted on a trailer frame at one end, and the other end connects to shackle straps suspended from the hanger or an equalizer. Now the length on the spring is always measured from the center of one eye to the center of the other. So if we do our tape measure center to center, it's gonna be right at 25 and a quarter inches. The width on the spring is one and three quarter inches, and the eye diameter with the bushing installed is nine sixteenths of an inch.
But that should do it for a look at the 25 and a quarter inch long 4-Leaf Double-Eye Spring for 5,000 pound trailer axles.

Thanks for sharing the photo, that definitely doesn’t look right. Leaf springs should not flatten out and bend like that after a single trip, especially with normal use. That usually points to the springs being overloaded or not matched correctly to the trailer’s weight. We’d want to take a closer look at your setup to figure out what’s going on. If you can share your trailer’s axle rating and what kind of load you were carrying, that will help determine if the springs were undersized or if something else is contributing. Really appreciate you bringing this up, we definitely want to make sure you get something that holds up the way it should.
