If you're replacing a busted or rusted-out spring on your trailer - or if you've decided to upgrade to dacromet to avoid rusted-out springs down the line - the first thing you'll need to do is measure your existing leaf springs. Take a look at the measurements above. If these dimensions - and the weight rating - match what you currently have, you should be good to go.
Remember, though, your leaf springs can flatten a bit over time. And if you're measuring your spring while your trailer is fully loaded, the overall length that you get might be a bit more than what you need a brand new, unloaded spring to measure.
As you travel across highways and backroads, your trailer's leaf springs are going to corrode and flake over time. This is especially true if you have a boat trailer that's regularly submerged in water. Completely rusted-out springs on trailers are all too common, and these dacromet springs are a great solution to that problem.
Longer-lasting springs will save you money and are great for any trailer, but they are a must have for folks who live or play by the water. If you live on the coast, you're probably always rinsing the saltwater off of your trailer to try and keep rust at bay. If you're really worried, you might've even tried to repaint your springs or spray them down with rust inhibitors. But upgrading to these dacromet-coated leaf springs could cut down on or eliminate all of that maintenance, leaving you more time to spend out on the water.
Rust-resistant coatings are graded according to a salt spray rating. Basically, this rating shows the amount of time it takes for a material to show signs of corrosion when exposed to pure, continuous salt spray. We conducted our own salt spray test and found that this dacromet coating lasts up to 744 hours before it begins to deteriorate. Compare that to some other dacromet coatings out there that are rated at just 300 hours - or zinc coatings that don't last for even that long - and you can be sure these springs will last.
Leaf springs, as you probably know, make up an important part of your trailer's suspension. Their main purpose is to absorb road shock as you travel, as well as allow your axle(s) to move independently of the rest of the trailer.
To mount this leaf spring, you'll need hangers welded onto your trailer frame - which you probably already have in place - as well as shackle straps and a suspension bolt. It's a good idea to replace your existing straps and bolt while you're under there working on things because they tend to wear out quickly. One thing that could help keep them from wearing out too fast would be upgrading to galvanized or zinc-plated hardware. Doing so will boost the corrosion resistance and, therefore, the longevity of your trailer.
We also always recommend replacing both of your springs at the same time because it's not unusual for leaf springs to sag and elongate over time. If you replace just the one, there's a good chance that it won't match your existing spring on the opposite side of your trailer, and that can mess up your alignment.

Hi everybody, Andy here with etrailer.com. Let's take a real quick look at this etrailer Dacromet Six Leaf Slipper Spring with hook end for your 8,000 pound axles. Now this spring is made of sturdy steel and it is designed to flex to absorb road shock and give you a smooth ride, reducing wear and tear on your trailer. And this is going to ensure a level ride on bumpy and uneven surfaces. This spring will do a great job of resisting rust and corrosion with the Dacromet finish. This has a salt spray rating of 700 hours and this is gonna be excellent for boat trailers or any trailer that's regularly exposed to salt treated roads.
This is designed to mount to your trailer frame with hangers or a hanger kit. Those items are sold separately, but if you are in need of them, of course you can find 'em right here at etrailer.com. In the eye is a pre-installed nylon bushing and the eye of this spring will attach to the hangar mounted on your trailer's frame and the slipper end slides into your hangar or equalizer. The eye diameter with the bushing is 9/16", without the bushing, it's 11/16". So this spring does contain six leaves.
The thickness of the leaves is 3/8", and this has a spring capacity of 4,000 pounds and it's designed for 8,000 pound trailer axles. And lemme go ahead and get my tape measure here and I wanna measure from the center of our eye to the end of our hook on the inside. So lemme see if I can line that up there for you so you can see. So from the center of the eye to the inside end of the hook, so I hope you can see there, we're sitting right at 29-1/2" long. The spring width, which you probably can't see from that angle is two inches.
And to ensure proper axle alignment and suspension performance, leaf spring should always be replaced in pairs and we do recommend installation by a professional. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
