Torsion bars with ranchos 4" lift.

[Hammer]

if I tighten up torsion bars can it cause problems. I have ranchos 4" lift with 9000xl shocks. I could easily gain 2" more lift.

I know there are some problems if torsion bars are cranked up if its done to stock H2 but what happends if I do the same thing to lifted truck with 9000xl shocks ...
