sorry simon t i just had to join in on this one!

why do you need pre load and what are you trying to achieve?

[RobC]

Spring rate doesn't change with preload, i.e. a 600lbs spring will always be 600lbs

[ScottHughes]

Sorry to but in guys but doesn't it also mean that if you run preload you will also have Zero droop?

Rob,
I'm sure I am being dim here don't quite understand your post.. are you saying that without preload that the spring rate changes?

[RobC]

Scott, what I mean't was a 600lbs spring will always be a 600lbs spring be it with no preload or with half-a-dozen turns of preload.

[Simon T]

Adding preload simply increases the amount of force that needs to be applied to the spring before it begins to compress more than the preload compression, it does not change the rate of the spring.

This might help, its writen for bikes but the priciples are identical
