        Bars have a specific twist built into them for left side and right side. Installing them on the wrong sides will cause stress loads opposite of the built in twist and cause premature failure. (The bars will snap)

          Unless you are going for a REALLY low, low rider look,

          Screenshot_20211118-121811.png

          or would it be a gasser look???

          Screenshot_20211118-122054.png

          Maybe a 4x4?

            The endings are clocked in opposite ways from side to side. Can't remember exactly but at the very least you'll f---k up your spring tension, and probably break the bar under load.

                They are pre stressed in the direction of spring rate so the right (passenger) is already twisted a little in its load direction, ccw. Also makes the lca mount up easier . Iirc you have to manually push the lca down a little against the bushing preload for the bars to slide in, or else loosen the bushings and have the lca just hang, bring load onto lca and tighten bushings at ride height.

                Just for shits and giggles. Do you know which side of your car is considered the right side and the left side? Not trying to insult but some people do have it wrong.

                  Depends on whether you standing in front of the car facing the car or sitting in the driver's seat???

                    Is this posted in the joke section? I'm so confused......

                    When it comes to auto parts, the sides are determined by the position of the driver in the vehicle, facing forward. Meaning, looking over the hood, and sitting in the driver's seat, your left hand is the left side, your right hand is the right side.

                        Yes, you are correct but sometimes the young, wet behind the ears, parts guys doesn't know that. So you can say driver's side or passenger's side.

                              You can install them on the wrong sides as long as you put them in backwards .

                                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” or “twisted” 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. The offset is built in, the bars are not made without offset and then twisted.

                                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.
