    Spring diameters

    by TRD » Sun May 02, 2010 3:16 am

    I have a little problem. I have 3 different diameter yellow springs for rear shock. I believe those are (4.71N/MM / 4.8KGF/MM) (5.20N/MM / 53.0KGF/MM) (55.9N/MM / 5.7KGF/MM.

    Problem is that I don´t find spring diameters what thickness each spring would really be? There are no marks in springs what they are. Little difference in thickness change spring rate quite much.

    And I think best spring for me would be (53.9N/MM,5.5KGF/MM) so I probably won´t even have one.

    So if anyone have thickness specs for different springs I would be glad. And measure without paint on spring. I believe there is only 0,2mm thickness changes.

    Here is a calculator. There are more if you Google Coil spring calculator.
