The 6" lift was alright, but most of the newer style lifts use a lift knuckle instead of dropping the upper arms. This usually increases your track width in the front a bunch and looks really weird. A lot of IFS lifts have alignment issues if you use them at all off road, although my RCD was ok in this respect. I just wished that I had saved my money a little more and either bought a different truck or done a SAS with it. I think for reliability the majority of opinions on here are very correct. Leave it as stock as possible or go straight axle. You could always just spend that money at a local body shop to have them trim the fenders and get everything looking factory again if all you want to run is 33's.
