Torsion Bar lift

[XJ-22]

I have a 1992 gmc sierra 4wd that I want to lift 2" or 3". I know i can just adjust the torsion bars to get that lift, but I've heard that you can buy new torsion bars, not keys, that will lift your truck and still keep the suspension just as soft. Any ideas? And if that is possible, where would I find them?

i was doing research but cant find anything on torsion bar only they all have to do with keys
