Torsion bar Warning

I hear what your sayin but, for the stiffer spring to compress the same amount as the light spring requires more pressure, i.e. weight in this case.
that t-bar socket was compromised somehow whether it be crappy build from the factory, somehow hammered in its previous life (think Dukes of Hazzard), plain old metal fatigue or something.
the bigger bars probably just made that socket fail sooner rather than later.

That's an excellent point. The forces acting on the wheel never change, they're determined by the weight of the car.Torsion bar suspensions are 1:1, so, the force acting on the wheel is the force acting on the anchor. The only difference is the amount of travel.

Where it gets sticky though is the impulse. The same amount of force is acting on the bar, but, since a bigger torsion bar has a higher spring rate, it deflects less. That takes less time then a smaller bar, which would deflect more, so, the same amount of force acts over a shorter period of time.

Either way, I think that anchor had a serious issue with it that would have come up sooner or later, regardless of the torsion bar.
