I have seen some of the suspension lift companies list their kits with date ranges from 97-02 & 03-06 for the TJ. I know the Rubicon came out in 03, but does anyone know the "details" in the difference of these kits? I have the 03 Rubicon, and am looking at the 3" or 4" lift to put 33" tires on it. I am aware of the SYE, but understand it may not be needed on the Rubicon. Is that all? Just looking to clarify so I can start deciding which system to go with, without waisting money, time, and unnecessary components! All details would be appreciated! Thanks!
