this ( Rustys Offroad: TJ 3" Basic Kit
) +upgrade to get 4' of lift will be a much better ride, better shocks, better coils, better everything and better driveline angles b/c only 3" of susp. lift
RC is known to have a rough ride, even in their name, all heresay, but I've heard it is very stiff and not built the best
rusty's will be OME, very nice people great quality and all around better, it is worth the extra $80!!
