Hey Matt, thanks for reaching out!

I'll need to know the length of your leaf springs when they are unloaded in order to help you find the right length. That and if you can let me know the length of your shackles (center eye to center eye) I can let you know what will work for your setup.

I've linked our selection of leaf springs and shackle straps for you to filter through, but I'll be looking through this same list when I hear back from you!

Hello, thank you for your help. I just checked and it’s 25 1/2 inches center of eyelet to center of eyelet unloaded. Also, I was hoping to get a little bit heavier spring. These are a four spring for a 5200 pound. Axle

@MattE Thanks! For that I recommend the 6K 5-Leaf Double-Eye Spring # e34SR. This measures 25-1/4" long so it's a little shorter than your current ones, but leaf springs will naturally elongate some over time so the 25-1/4" length will still work out just fine. What is the length of your shackles?

@JonG 7 inches across for the one that goes from leaf spring to leaf

@MattE Are you needing to replace the equalizer, or your shackles? The equalizer is the pivoting point that connects to the hanger, while the shackles are the small metal pieces that connect the leaf spring to the equalizer. And do you have a 2-axle or a 3-axle trailer? In your first post you said 3-axle, but in your comment, you said there are 4 springs which would mean it only has 2 axles.

Choosing the correct brake assemblies will depend on the weight capacity of your trailer's axle and the size of the brakes. A 2,000 pound axle will use 7 inch brakes like #AKEBRK-2. A 3,500 pound axle will use 10 inch brakes like #AKEBRK-35-SA.…
