re: fitting tires/rims on my truck, advice?

I haven't put the kit in myself, I'm getting it professionally done. I will say it costs a good bit more than getting the regular 2" leveling kit installed. Also, a shop I spoke to today suggested getting the new upper control arms for alignment, but I am not sure how necessary this is. As for the ride quality, RC says you will keep the same ride quality, but I have not gotten the lift/level put on yet so I cannot provide any feed back on that.

Anyone know about the control arms whether i really need them or not?
