X3 keep your existing SS. Often aftermarket SS's are too strong and cause your jeep to wander one direction. I have seen this problem several times here on WAL, and the solution is always to go back to a stock SS.
FYI- I have no steering stabilizer on my Tj with 40s. I think it does just fine.
My ride- 2001 power wheel, 11" plastic tires, upgraded battery, boat sides, custom bumpers, tow hooks, new paint.
