Don't lie to the new guys corrupt, we all know those are 31 x10.50's.
Ohio, one of the reasons you are getting so much flex is the 2" shackle lift. Longer shackles mean more swing. Long shackles are also the reason that some vehicles handle poorly on the road. This can be countered by a track bar. Nice looking Jeep though. If it works for you, there is no arguing that.
Why is it that no one ever throws Skyjacker in these threads? It's either the el cheapos or Rubicon Express these days. Skyjacker was the shiznit back when I started wheeling years ago.
Back on topic...whenever you weigh your options, it is also nice to consider whether the spring you purchase has a "military wrap" or not. This means the secondary leaf also wraps around the eye in addition to the main leaf and may save your butt should your main leaf ever break. I know BDS springs have this, but not sure who else.
IMO, Superlift as a company does a lot for this sport, but their springs are usually the stiffest available and the shocks are no better. Their Black Diamond coil kit on the other hand is impressive. They also make rad t-shirts.
