OK or no?

So if I go to lift my truck by cranking up the torsion bars, will this mess with my ride or make my suspension parts wear out fast? I don't want to do anything I regret in the long run. Thanks!

If you crank 'em too tight against the bump stops, you can cause wear a little faster...
But more importantly, the ride will be uncomfortably stiff.

So would about 2 inches higher be too much? Or what would you recommend?
