Double-Eye Dacromet Springs Diagram

Part NumberABCD
e88SR13"14"26"4-1/4"


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.


Rustproof Your Trailer Suspension with Dacromet

Double-Eye Diagram Dacromet

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.


Dacromet Versus Rusty Springs Comparison

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.


Double-Eye Leaf Spring Basics

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.


Double-Eye Spring Parts

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.

I have not pulled our travel trailer at the time of this review. However I don't expect any issues once I move my travel trailer.

Installation was fairly easy since I installed a similar size last year. Representative was helpful and understood my dilemma and tried to get the product to me as quickly and as cost effective as possible.

While waiting for the product to arrive I decided to buy another one at a local rv parts as a backup, but they sold me the wrong size. The told me it was a 26 inch, but it was about an 1/2 inch to long, and it made a difference when installing it. The fit did not look right so I took it off and installed etrailer's leaf spring and it worked just like the previous year.

What a wonderful experience in dealing with Etrailer on this project. I Love the springs and the customer service was absolutely incredible. They took what could have been a nightmare and turned it into a great ending!



by:

Received material in a timely manner and everything fit! Great job etrailer!



by:

Installed perfectly. After 1 year still look and function great.



by:

Good product. Bolted right on with ease to my tracker trailer. You need to purchase the longer u bolts because the stock ones aren’t long enough. Made a big difference in ride quality of the trailer.



by:

I ordered a set of springs that were not adequate for my application. Called and asked about returning them and getting the 4,000lb set. The answer was yes and the new ones were shipped that day on a Sunday and arrived here in Texas a couple days later. The springs fit perfect and can handle the load quite easily. What a seemless and efficient process; especially Allison K for taking care of me!! Thank you to her and everyone at etrailer for having superior customer service. Keep up the great work.

Arrived early and coating seems very durable. Huge upgrade over the stock springs on my boat trailer!

  • Upgraded 26 Inch Leaf Springs For 3,500 lb Axle on Tracker Boat Trailer
    Smart idea to get ahead of the problem, and there is a good upgrade for your Tracker boat trailer with a 3,500 lb axle. Since your current spring measures 26-1/4 inches from center of one spring eye to the center of your other spring eye, a 26 inch spring will be right, because leaf springs elongate and flatten slightly over time. So the best option is the following: - 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long - Dacromet # e48SR The # e48SR is for axles up to 4,000...

  • How To Choose Correct Replacement Leaf Springs for a Tracker Boat Trailer
    In order to find the correct replacement leaf spring for a trailer you first need to start by noting the type whether that be slipper or double eye. Then, you'll need to measure their unloaded length via jacking up the trailer/boat. If the springs are worn they will measure longer than their replacement. Lastly, you will need to note the axle capacity which is found on the tag in the center of the beam. Please note, the number of leaves does not really denote capacity as leaves have different...

  • What is Salt Spray Rating for Galvanized etrailer Leaf Springs
    I checked with our engineering dept and they said the salt spray rating for our galvanized springs like the # e48SR is 700 hours. That is a huge difference and in my opinion easily makes it worth the extra money over non-coated springs especially for a trailer that will see saltwater. The finish will not come off either.

  • Does Going to Higher Rated Trailer Axle Require Higher Rated Leaf Springs
    If your plan was to take advantage of the additional weight capacity by using the higher rated leaf springs then yes you'd need higher rated leaf springs like the # e48SR but you should keep in mind if your trailer frame isn't rated for higher weight capacity then you'd still be limited by that.

    I'd be happy to help you find new leaf springs for your 2020 Tracker Targa V18 Tandem Axle Trailer, but there's no database that says what length leaf springs you have or what capacity they need to be. The first thing you'll need to do is jack the trailer off the ground and allow the axle to hang so no weight is on it or the wheels/tires. Once that's done you'll need to measure the leaf springs from center to center of the spring eyes as shown in the included diagram. Second is you need...

    I can help you determine the right replacement leaf springs for your 2021 Shadow Cruiser 248RKS, though we don't have any way of knowing what specific ones you need. It's pretty easy though, as what you'll need to do is measure your current leaf springs from center-to-center of the spring eyes, and you also need to know the weight rating of your axle. I looked up your trailer's specs and you likely have 3,500 lb or 4,000 lb axles, but you will want to verify. Also keep in mind leaf springs...

  • 4k Replacement Leaf Spring for Trailer with 3,500 lb 26.5 inch Spring
    The correct leaf spring replacement you'd want is the part # e48SR which is 26 inches long and for 4,000 lb axle like you have. Typically the best way to measure springs is with no load on them but based on yours being 26.5 with a load a 26 inch spring would be most likely best fit.

You will need to measure the springs on your KZ to verify the correct replacements. As this measurement is from eye center to eye center with the springs relaxed the easier measurement is measure along the curve of the spring from eye center to center of spring pin. The 26" spring will be 14" while the 25-1/4"...

    Dexter 4,000 lb axle leaf springs like the part # e48SR for 26 inches long or part # e57SR for 25-1/4 inch would work great with a 3,500 lb axle. There would be no issue with 1,700 lbs of weight either.

  • Replacement Leaf Spring Recommendation for 26 Long Leaf Spring on 3,750 lb Axle
    The 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # e48SR is a good replacement for your boat trailer as it meets all of the specs and is compatible with an axle that's just a little higher when it comes to weight rating. Please note that what you do to one side of the axle you need to do to the other so you'll need 2 of these leaf springs.

  • Determining The Correct Replacement Leaf Springs For A 2021 Keystone Passport Grand Touring TT
    You could potentially replace your leaf springs with a larger capacity spring but will need to match the length of your current leaf springs to avoid having to remove and reinstall the hangers and rest of the suspension system, which is a giant hassle and a lot more costly than just replacing the springs. If you have double-eye leaf springs you'll need to measure from the center of one eyelet to the center of the other. If you have slipper springs then you'll need to measure from the...

  • 26 Inch Leaf Spring With at Least 3 Leaves For 3,200 lb Axles
    You're 100% right, Wes. For axles with a 3,200 lb rating you would need higher rated leaf springs, and for 26 inch long springs we have both standard and dacromet leaf springs that will work. Dacromet are great because their coating gives them rust protection that's perfect for boat trailers, though I did want to give you the option for both. Each rated for 4,000 lb axles (so 2,000 lbs per spring): - Dacromet: 4-Leaf Double-Eye Spring # e48SR - Standard: 4-Leaf Double-Eye Spring # e22YR

The Dacromet is better for boat applications but there isn't any harm in adding them to a standard setup either. I do recommend verifying this length is correct with your...

    Feel free to send me the pictures you have via email. If one side of the suspension hangers doesn't have a shackle setup you'll need to install some so that suspension can extend as it compresses. Otherwise it won't function well since the spring would have no where to stretch to as it compresses. For 3-1/8 inch shackles we have the part # TRSL313. Then for a shackle bolt that comes with a nut you'd want the part # 166081.
