making a 6\" work what will i have to do as far as drivelines go to my suburban to make a 6" lift work w/o vibes. shims, t-case lowering, shaft lengthening... what needs to be done? i have a 10 bolt front 14 bolt SF rear and an np241. will the extra length of my suburban make the rear shaft act funny or better? my front shaft is the same length as a K5's right? oh and brake lines, my fronts are 8"ers so i'm ok there but what about the rear, i have skyjacker SS braided lines up front do they make a line for the rear?
