I'm thinking about replacing my 2.5" Metalcloak / OME Nitrocharger shock combination with 3" EVO / Rancho 9000 shocks. I am looking to improve the ride quality. The firm spring/ soft shock combo isn't working for me driving around M-F. Everything I've been reading and been told is the EVO/Rancho combo should prove to be better for me. So, that said, I know that Rancho has a couple different parts. They have 999329/999330 or 999331/999332. I am thinking 329/330. But can I do the longer 331/332 and not worry about the springs becoming unseated at full droop? I know I could do spring retainers. Those running Rancho 9000 and EVO 3" plush, which parts did you go with?
