violent vibrations
My Cuda has the left torsion bar cranked in a lot farther than the right. I thought it might be a weak bar and replaced them but it's still the same. It doesn't make sense either cause the engines on A-bodies are offset 1-3/4" to the pass side so you'd think you would have to crank the pass side bar more cause the weight is shifted that way. Go figure!!
/6 torsion bars are good drag bars because they react quicker to transfer weight. Only problem with them on the street is their so light it won't handle as well.
If yours were installed wrong I wouldn't swap them around. I'd replace them.
