Your springs need to meet the flat or 0 arch point at the same time your bump stops reach max compression. After that your shocks need to reach max compression at the same time your springs do "DURING ARTICULATION"!!!! Shortening the shock for more up isn't going to do you any good if the bump and spring wont allow it. And running your leaf springs past 0 is a quick way of destroying your springs. The length of shock should only affect the down travel of the spring and the bump should set the bump travel on the shock and spring!!!!!!!
