2'' BB or 3/4'' or 1'' rear spacer
go with the teraflex 2.5BB you wont be sorry, also if your thinking of doing a 2" lift now, chances are you will want to mod further up the road, I think the 2.5" is perfect as you dont have to worry about changing lots of suspension components, everything you need is in the box and there cheap aswell.
I just put rubicon express bb in wifes jeep 2010 2 door prob taking out to do 2 1/2 " teraflex she says it drives to stiff kits only been in a week prob take out next week looking to sell pm me if interested
