I picked up some torsion bars from the salvage and they seem to be a little bowed. Can't tell by looking but if laid on flat surfaced and rolled they are heavy on one side. I pulled them and they came out fairly easy. Should I be concerned or is this a normal thing. Truck did not have any frame damage. Was rolled over.

Lighter rated torsion bars will tend to do that. Most are found on the 1/2 ton trucks. Do the ones you bought have their labels still on them? Here is the list of all the GM torsion bars and their ratings for reference. The further down you go, the heavier rating the bar has.

I wouldnt bother. Whats the reasoning for getting them anyways? If your current bars are sagging look into some GL or GK bars.

It really doesn't matter why I have these I just wanted opinions on the sagging. If I should use them or not. Not a offroad truck. Street driven only.
