Replacing Torsion Bars

Here's my figuring and reasoning FWIW.

1) Since the offset on the tbars is 20°, the left and right bars are not interchangeable.

Since the angle difference between the flats on a hexagon is 60° (360/6), a 20° offset would set the lower control arm angle incorrectly when installed. If the offset was 30°, then it would be correct regardless of the side installed on.

2) Installing the torsion bars front to rear, or rear to front would have no affect on the offset angle, therefore the lower control arm angle would be correct. However, the twisting motion would change from clockwise to counterclockwise on the bar (reverse on other side of car).

If there is an equal spring rate twisting in either direction then they should be able to be reversed front/rear. If they are designed to have a different spring rate in one direction from new, or if this occurs once the springs have been used, then they should be installed one way only,and reversing them would be incorrect.
