Leaf Spring Replacement and How to Find the Correct Measurements

Updated 08/17/2021 | Published 08/15/2021

Question:

I am positive my leaf springs are worn out to the point that they will not reflect an accurate or correct eye to eye length measurement. I have a tandem axle enclosed trailer with 3500# axles. How do I find out the correct size?

I'll be glad to help you find the correct set of leaf springs for your trailer but I am going to need some more information.
This is a common problem because springs like to flatten out as they wear. The best way to get an accurate measurement is to jack the trailer up so that the axles hang free. Then measure straight across the springs from the center of one eye to the center of the other eye on each spring. This will give you a close enough measurement, within 1-2 inches, that you will need to find some replacement springs. Each of our product pages for the leaf springs shows a diagram showing the width and height of the spring. If you let me know your measurement I will be happy to pick out the right replacement.
