How far can the ride height be increased on a 2002 Dodge Ram 1500 4x4 by cranking up the torsion bars without causing any permanent damage to the suspension....will a good alignment be fine if the torsion bars are cranked up?

I went from a stock tire size of 245/70/17 to 285/70/17 mud terrain tire. The tire store I went to obviously adjusted my torsion bar suspension higher and then did the alignment.
