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.

So far, so good. I upgraded from a 4 leaf to a 5 leaf spring because I was breaking the four leafs about every 2 years. These have performed very well for at least this first year.
2009 Cedar Creek, The previous owner had new axles installed in 2014 with wet bolts and equa-flex . The springs had flattened out because of age so finding the right length was hard. One call to etrailer helped with this, I ordered the upgrade shackles with wet bolts. I was surprised by the quality and thickness of the shackles! Installation went well about 3 1/2 hours. I found that the previous owner used nylon bushings instead of brass one. They had worn thru but the brass ones on the equa-flex were like new.
Look great. Shipping was on time. Jesse was great to work with.
