mhlbr,
The KORE Technical Series is 5. 5" of lift, and has one of the nicest street rides we have experienced. Very good for washboard type roads as well. 37's fit without fiberglass fenders. It's not what were known for, but it is a great riding suspension with more lift. Jeremy at DRC has the exact system on his Megacab.
I have driven in several other lifted Dodges, and many times they were nothing but scary. I prefer to keep them as low as possible, but some guys really like there trucks with a little more altitude.
Shop around and drive a truck with each of the suspensions you find. It is a little risky buying a taller lift without experiencing it first.
