Nearly a year ago, I added a 2.5" Rubicon Express Budget Boost. I got the shocks with the kit and it's been a good lift with the stock springs. With what I have, if I want to go to a 2.5" or 3" Coil Lift, do I just need to pick up front and rear springs? Anything else I need to make the change? I'd like to get a little better ride, a little more lift and if possible, get the front lifted a little higher to address the rake. Let me know if this makes any sense to do. Thanks!
