MEASURING TRAILER SPRINGS

MEASURING TRAILER SPRINGS
There are 3 basic types of springs for boat trailers.  These are: Double Eye, Single Eye, and Hook or Open Eye.
The following is some guidance on how to measure each type of spring.

Double Eye spring measurement: Measured from Center of Hole (Eye) to Center of hole.

Single Eye or Slipper Spring: Measured form Center of Hole (Eye) to Center of tip where Frame of trailer would rest.

Open Eye Spring: Measured from Center of Eye to center of Hook.

There are 1 leaf 2, 3, 4, 5, 6, leaf springs. When measuring to replace springs, it is best to measure where they mount hole-to-hole as the old spring tend to have flattened out and are longer that they were when new.
The most common springs are 20″ double eye, 25-1/4″ double eye, 24″ single eye, 26″ single eye.
