When I bought my 04 tj it had these coil spring spacers already installed. I want to know how much of lift there is, so I was going to measure the height of the spacer, but it looks like there are two spacers. The big one has 4 “sections”, but above that is another puck that looks like a spacer as well, but maybe that is stock? Does that come on them from the factory to hold the spring in place?
