I personally would never pay $500 for that kit. It does not include a lot of other components that are essential. There are many other "more complete" kits on the market that include new springs, nessasary brackets... The list goes on. If you want a small lift to clear say 31s, the simple 2" or even 1 3/4" spacer will do and you CAN keep your stock shocks. If your feeling hungry to go higher, it's gonna cost more money, not just for the lift but for all of the other components needed to do it right. I have been looking at getting a 4" Zone lift for my 99 TJ, I've read a lot of good reviews and there is a vendor here Alans offroad that I think hooks us members up with a deal.
