Bumpy roads can rattle everything inside and wear your suspension down fast. This 4-Leaf Double-Eye Spring flexes to take the edge off those hits so the trailer rides smooth and level. The stacked steel leaves share the load and soak up road shock, cutting vibration and bounce to protect your gear and your frame. Each leaf is 1/4"" thick, giving the spring the strength to handle real-world miles without sagging.
When you’re hauling heavier setups, you need springs that can keep up. This spring is rated for 3,000 lbs per spring, making it the right match for a 6,000-lb axle. The 25-1/8"" eye-to-eye length and 1-3/4"" width give it a solid stance under load while keeping the suspension geometry right where it should be. It’s a dependable choice when you want a firm, steady ride and consistent height even with a full trailer.
Loose or worn spring eyes can throw your alignment off and chew through hardware. This spring comes with nylon bushings pre-installed in both 9/16"" eyes so you get a snug, quiet fit from day one. The smooth-fitting bushings cut friction and help the spring pivot cleanly as the suspension cycles, extending the life of the bolts, shackles, and hangers it mates with.
Swapping out tired springs doesn’t have to turn into a project. With a 25-1/8"" eye-to-eye length and standard double-eye layout, this spring bolts right up using typical hangers, shackle straps, and suspension bolts. It works with pre-mounted hangers or aftermarket kits (sold separately), so you can drop it in and get back on the road. Replace both springs at once and your setup stays even, balanced, and ready to roll.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this 4-Leaf Double-Eye Spring for your 6,000-pound trailer axle. Now, this double-eye leaf spring acts as part of your trailer suspension system by providing an attachment point for a 6,000-pound trailer axle. It is made from a sturdy steel construction, and this is designed to flex 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, double-eye leaf springs attach to hangers that are welded onto your trailer. One end of the spring will attach directly to the hanger with a suspension bolt. 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. Now, if you have a tandem or a triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. So if you need 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 bushings is 9/16 inch. Without the bushing, it's 11/16 inch. And again, this is going to be a 4-leaf spring with the leaf thickness of 1/4 inch. And by itself, it has a spring capacity of 3,000 pounds, and, again, when paired with another one on the other side, that's where you're gonna get your 6,000-pound trailer axle capacity.
Now, let me see if I can line this up here for you on camera. Measuring center of eye to center of eye, you can see we're sitting right at 25-1/8 inches on center. The width of this spring is 1-3/4 inches. Now, additional dimensions with a diagram are available on this product page if you're looking for some more measurements. And of course, to ensure proper axle alignment, I'm sure you know leaf springs should always be replaced in pairs, so that's gonna help with proper axle alignment and suspension performance as well.
If you do decide to pick this up, we would love to hear back from you regarding the installation and the operation of the spring. You can share your experience with us by leaving a comment or a review on this product page. If you leave a review, you can also leave us some photos as well showing this spring on your towing set up. Well, that's gonna wrap up our look today. I do hope that it was helpful for you. 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.
