The below paragraph is from the Progressive suspension website. The amount the spring is compressed by the amount of preload is what determines loaded ride height plus many other factors.
My original question was based on leaving the spring in a more compressed state ( via high preload setting per below paragraph ) I was just wondering if I would get longer, useful spring life by leaving it in an uncompressed state when not in use by backing off the preload ?
Look at two identical shocks, one with full preload, and one with no preload. The shock length is the same, its the overall length of the spring ( because one has been compressed ) that will be different.
Below is from Progressive site:
"This is where Preload Adjustment comes into play. By compressing or uncompressing the spring a small amount, a shock can be perfectly tuned to suit the conditions for which it will be used."
I'm thinking an analogy might be similar to why it is important to back off the preload to zero on a torque wrench when not in use.
