I was looking at the RE 5.5" lift for my XJ. I currently have a 4", but it is going to cost me $800 to fix all that is wrong with it. I really want to go higher and now is the time due to things wearing out. The RE will set me back about $1780 due to me needing SYE, CV and a stabilizing shock. Ouch. I am running 31's and hope that will look ok if I go that high. Those tires are not worn out yet.
What other lifts have a good rep?
