Anyone have any good sites to the theories reguarding leaf springs? I know we don't talk about this often, but we take for granted all the factors that go into building something that we look at as so, "Simple" as a leaf sprung suspension. I feel that with all the factors surrounding this issue, it's about time for a good discussion. http://www.rpmnet.com/techart/leaf.shtml That one, while interseting, states at the top that it only applies to springs with the shackles above them (compression style) Does this mean the whole theory changes when a tension style shackle is used? Also, according to that site, by changing my shackle angle to less than 90*, I have effectively stiffened my front springs. This seems completely impossible, but if true, compeltely disproves my theories on why we all should move our front shackle mounts to achieve a better shackle angle. Not only that, but if that site is true, we should be moving our shackle brackets back for less angle to soften our rear springs for better off road performance. This seems like a complete contradiction, and it's about time for a discussion on this. I don't feel that this belongs in the COG, but I think it's about time we had a complicated discussion about something we dismiss as such a simple piece of equipment we call the leaf spring. So, folks, what have you got?
