Industry standards for springspermit an initial variance of /- 10%. To thesesprings for greater initial tension, up to 3 spring shims part # 203849 may be used with most of them. Bottoming out of a spring coil upon coil even once will hasten itsdeterioration so avoid using 3 shims if the bottoming out condition should result.
