Salt, water, and road grime can eat away at suspension parts fast. This leaf spring has a dacromet finish with a 700-hour salt spray rating, giving it serious rust resistance compared to standard steel or zinc coatings. Whether you’re towing on salt-treated winter roads or backing into the water, the coating keeps the steel protected so the spring stays strong and lasts longer.
Rough roads and heavy cargo can beat up a trailer suspension. The 4-leaf double-eye setup absorbs bumps and road shock so your trailer tracks steady and tows smoothly. Each spring supports 1,750 lbs, pairing up for 3,500-lb axle capacity. The 27" eye-to-eye length and 1-3/4" width match standard suspension geometry, restoring a balanced ride when old springs start to sag.
When it’s time to swap out worn springs, you don’t want to fight with measurements. This spring mounts to your existing hangers using standard suspension bolts and shackle straps. It includes nylon bushings with 9/16" eye diameters (11/16" without), so the fit is straightforward and solid. Just replace both springs together to keep axle alignment right where it should be.
The sturdy steel construction gives this spring the backbone to handle years of use, while the dacromet coating cuts down on the constant cleaning and repainting that rusted springs often need. It’s a smart upgrade for anyone tired of flaky, corroded parts and wasted time on maintenance—install it once and get back to hauling without worrying about rust taking over.

Hello, neighbor, Steven here with etrailer.com. Let's take a look at our etrailer rust resistant four-leaf double eye springs rated for 3,500 pound trailer axles. Now folks, these upgrade your trailer suspension or replace your current suspension to save you time and money on maintenance. They are gonna be excellent for both boat trailers or any trailer that's regularly exposed to salt treated roads, so it resists rust and corrosion with our DACROMET finish that has a salt spray rating of an impressive 700 hours. Now folks, these mount directly to your trailer existing hangers with suspension hardware that's all sold separately. And these are constructed of a nice sturdy steel construction.
They already have the nylon bushings pressed in place. Now you're gonna get one leaf spring just like you see here. We recommend you change out both of 'em, so both of them meaning left and right side of your trailer. That way you have proper axle alignment and sometimes brand to brand, there could be some slight variances in the length overall, even though they all say the measurement and possibly the spring material. So it's a good idea to replace 'em in pairs.
Now this spring by itself is rated at a capacity of 1,750 pounds, two of them giving you that axle capacity of the 3,500 pounds. Now center of eye to center of eye on this spring is 27 inches. The spring width is 1 3/4 inches wide. And the eye diameter with the bush in here is a 9/16 and without the bush in here, the diameter of the metal itself will be 11/16. Now the leaf thicknesses are 3/8 inch thick.
There are four leafs, so you can count 'em one two three four. And they've got the nice clamp here and metal heavy duty to hold it together. And then you've got the spots here to set onto your spring seats and everything on top of your axle. And then of course your U bolt and plate that again are sold separately. If you need some new ones, pick 'em up here at etrailer.com, but those will go on the top.
Well folks, that's gonna wrap it up for a quick look today at the etrailer rust resistant DACROMET coated four leaf double eye spring 27 inches long eye to eye. I'm Steven. Thanks for watching.

That's awesome to hear! Six thousand miles is a great real-world test, and I'm glad the springs are still holding up so well. Thanks for taking the time to come back and share your experience. What kind of trailer are they on?

I would say they are holding up great against that pesky salt water Eric. What kind of boat do you have on that trailer, and what body of water are you getting out on mostly? I am out on the fresh water quite a bit out here in Missouri.
