Helpful Expert Reply:

To measure for the correct leaf spring length, you should jack up the trailer so that the axle hangs free, then measure straight across from the center of one eye to the center of the other eye. Because springs tend to flatten out as they wear, this the best way to get an accurate measurement.

Each of our product pages for the leaf springs shows a diagram showing the width and height of the spring.
