Just out of curiosity, I was talking to a guy at an offroad shop and he told me with the new Rough Country X-series lifts, If i have a 4" and i want a 6" the only component Id need to change is the coilovers.

I am not too experienced with suspension so im skeptical, but if thats true it would be very convenient when i move back from Germany to upgrade to a 6" if i wanted or go back and forth between springs depending on what i wanted at the time. (obviously depending on drive shafts and adjustments to track bar, control arms and drag link)

Can anyone confirm this? i seems too easy. Hence my skepticism.
