Do Longer Leaf Springs Require Relocation of Trailer Spring Hangers

Updated 07/23/2014 | Published 07/21/2014

Question:

If I go from 25 1/4 inch 5 leaf springs to 25 7/8 inch 6 leaf springs, Do I need to relocate the spring hangers? Thank You!

It is quite common for old worn-out leaf springs to measure longer than they were when new. This elongation is one part of the wear process. The modest length difference between the 25-1/4-inch and 25-7/8-inch springs you reference is small enough that hanger relocation should not be necessary.

Spring length should be measured with the springs removed from the trailer. If still installed on the hangers and under any load the spring will not measure the same as when removed from the suspension.

The number of leaves in the spring does not necessarily reflect its fit or its weight capacity. You might refer to the linked articles.
