I would confirm what springs you have before messing with the spacers. My tj106 springs are 12" tall as well and they go with the 2" spacer for the 4" lift. Not sure if the tj104 spring is shorter or just has less spring strength so you may have the right equipment already. The rear springs should take less than 20 min to put in so I would just throw them in real quick and see how much lift you have. That way you will know what you have and whether you need to locate new springs or get the 1.5" spacer instead.

If all else fails, get a hold of the guys at upyourkia.com, very helpful info regarding this stuff! <img src="/forums/images/graemlins/cheers.gif" alt="" />
