Torsion bar upgrade

Basically, torsion bars are like a spring that's been uncoiled. Thinking of them like that might help you understand them a bit better. Going to a larger diameter will stiffen up the ride a bit. Can't tell you from personal experience how much difference it'll make going from a .81 to a .92 bar will make. I know that I switched my 64 from the stock V8 bars it came with to a set from a 340 Demon & it stiffened up the suspension quite a bit. Not objectionable though.
