ok here is another question...what does moving the shock position on the towers and arms do?....if i go in on the tower,do i have to go out on the arm?...and visa versa?....what does this help? when the shocks are laid out what does that do?....when the shocks are more straight up and down,what does that do?...im trying to get my truck dialed and this is 1 of the most confusing things for me
