SkyJacker comes with 4" springs, which leaves you about 1" up in back. I may replace those with 5.5" BDS springs eventually, I prefer the tail to be up - otherwise when I load it she looks tail heavy. Most kits seem to come with big blocks - I really don't like blocks, although the SkyJacker springs get used with the stock blocks and I would still use them if I do the BDS springs.
