I'm a new jeeper myself, but I'm pretty sure thats not a "suspension" lift. I ck'd their site and they do call them suspension lifts, but for $190, more BB. And my understanding is over 2" on spacers is the most you really want to go with. I'm sure more experienced members will chime in.
Daystar's "suspension lift" is nothing more than a 3" spacer. As Legman68 said above, 3" spacers are not something any experienced TJ owner would recommend. Spacers that tall can cause overcompression of the springs, damaging them.
Remember that having a different opinion doesn't also require one to be a jerk when expressing it.
wow good thing I searched for this subject, I was also looking at that lift/BB....not anymore. CMEvans79 which 2" system did you go with? I think I am going to go that route myself for right now and see where I end up.
