Good grief.
All factory torsion bars and most aftermarket torsion bars have a right and a left. That is because hex ends of the torsion bar are offset from each other, the points and flats are not aligned. Factory bars carry a 20 degree offset. That offset or clocking is used to set the angle of the lower control arm relative to the bar, which determines ride height.
Now, for the bad information. Torsion bars are not “pre-stressed” in any direction. If the bar is new it has not been “stressed” in any direction and installing it on the wrong side will not cause the bar to snap. It will screw up your ride height adjustment, possibly to the point that a normal ride height can’t be achieved, because of the clocking on the bar.
If a torsion bar has been installed and run on the car, it has been twisted in a certain direction and should always be used on that side of the car in the future.
Aftermarket torsion bars are not always offset or clocked. Larger torsion bars frequently use zero offset, and some of those bars are not marked R or L. When new they can be installed on either side, it doesn’t matter. Once run on the car they should stay on that side. Those folks that ran the older style zero offset PST 1.03’s received instructions saying exactly that.
No sir, 100% incorrect.
