I bought a set of Old Man Emu HD springs from a jeep forum and installed them today. Went pretty well except for the front. We (me and a coworker) thought we'd be able to just pull the old springs out and put the new in with just a compressor, but I needed to remove some things to make the axle drop lower. I got about a 2" lift from them overall. Now I just need new shocks and quick release front sway bar end links.
