K-Frame ID

I have never broken a torsion bar. I have seen exactly 2 broken bars. One broke where it had a nick in it and the other was in a Demon a buddy had when we were kids. We didn't know about the importance of left and right and putting them back where they came from. As long as you put them in according to how they are marked (left and right) and make sure they are nick free from end to end they will be fine in most cases.

I agree with you when it comes to new springs. I worked in a spring shop for 15 years. In fact I made the rear springs that are in my charger. I've seen more than my fair share of broken or sagged leaf springs and coils.
