i got a rustys 4.5 and its pretty good. I would recomend getting the heavy duty trac bar with the new frame bracket, and make sure you really tighten the axel end of the trac bar to torque specs, otherwise you will create problems for yourself down the road. I put t-case spacers and i had very litle vibes with the 4.5 without the sye, but i ended up putting a sye on anyway as soon as i could afford it. But really, whats the point in asking if its a good lift if you already bought it? I will say that IMHO rustys shocks suck and they rust really fast. I would also consider getting adjustable uppers and lowers which will aid alignments, and caster and will help prevent DW.
