In addition to what Phil said. Torsion bars are simply replacement for other types of springs. It has adjustability though the adjustment bolts.

Just like other springs, bars have certain spring rates - softer for lighter vehicles, thicker for heavier vehicles. Simply putting thicker bars in place will not increase the height of the vehicle unless you turn the adjutment bolts to do so. But when you turn the bolts then, you have a much harder ride due to the heavier spring rate.

Besides, I doubt there is tremendous difference between 1 ton T-bars and the H2's. The H2's weight is probably pretty close to the 1 ton's.
