I have the RC 2.5 with the 2.2 shocks on now. It rides better than stock by alot. People diss RC for having poor quality products, but from my experience they're great and have great customer service. The shocks could be a little bit better but they're fine for now. Things I'd recommend to get with the lift are the sway bar disconnects, trac bar relocation kit and bump stops if you choose to go that route. Good luck with your decision!
BDS is a much better product. RC dose not QC their stuff very well where as BDS stand behind everything they make. another option is to look into the Zone Offroad Products. BDS owns Zone and uses the same springs between the 2 of them. they are just a little cheaper.
Rough country is low quality garbage. I made that mistake once, and I'll never make it again.
Their customer support is great, but I don't wanna replace suspension parts often. People use their customer support as a crutch for reviews. That's crap because you have to call them all the time when their junk breaks.
I did look at Zone tonight and it shocks and spacers. I'm looking for the full blow suspension lift and I'm going to research on BDS. They may be shorter but sounds like a better deal. I like RC also but this is my 1st lift and my DD. I've heard about RC problems and there good points also. I don't know a lot about BDS. So I'm doing more digging at work tomorrow.
