Ride quality is basically unchanged, although you probably will lose a few hundred lbs (at most) carrying capacity. This would only cost you the price of the used springs (I bought mine from a guy with an RT that bought a lowering kit, he only charged me shipping, I think it was like $15....he was from this forum).
The rear coils on an R/T must be different then
I put a Ground Force 2/3 Drop on my RCSB 4x4 and the stock rear coils are standard, only the new replacement GF coils are progressive.
Stock left, progressive right...
I love my leveled 4x4, Front only dropped about 1.5", rear a bit over 3.5" and still room for large wheels/tires ...currently running 305/50R20's with my 2/3 Drop.
The ride quality is 10x better than stock, and so is the handling when I toss her aggressively into a tight corner....has never bottomed out.
