Measuring a Double-Eye Trailer Leaf Spring Length to Find a Replacement

Question:

Trailer mounted shackles are 26inch center to center. This is for a small boat trailer pretty much has 2000-2200 lbs on it 24/7. When searching site for 26inch springs it appears to show me ALL springs you sell, and the 1st one I came across that was 26inch was for 2ton+ axle. Help.

When measuring a trailer leaf spring it has to be done with no weight on the spring. You can do this by jacking up one side of the trailer and measuring the spring on that side. Or by removing a spring. It is likely that the springs on your trailer are shorter than 26 inches eye to eye.

They also tend to flatten out some over time. I suspect that you actually need a 25-1/4 inch spring but measuring without the weight on the spring would be the way to determine what will fit. I have included a link to the double-eye leaf spring main page for you so you can see the springs and their capacities all in one place. I have also included a link to our help article on double-eye spring suspension for you.
