x2 on the Rancho 9000s, they are actually doing a deal right now, free remote air ride control with 4 9000s. That gives you the ability to dial the shocks to a softer ride, or stiffer pending conditions. 4 wheel parts was have a huge sale a month ago, I got 4 of em for around 60 each IIRC. They are normally around 100ish each.
