Hard to say, I haven't heard much about them. For that price you can get the Superlift 4" kit which comes with an almost identical parts list, and you can buy it for about $575 as well. I would pick the Superlift kit over the Rough Country.
The Rough Country may be OK for a DailyDriver but won't hold up to very much Offroadin.
Might want to look at Full-Traction's 3" econo + shocks is only $100 more and FREE shipping from Northridge4x4. He can update later with the arms if He wants to, for a much better complete suspension set-up. Can run 35's with this 3", more like 4" kit.
