Torsion bar clocking

With factory bars; No that is not possible.
however, it is possible to wind a T-bar bolt up, and the business end Not be in the Socket.
It's also possible that the Socket in the Cross-member is torn out, and factory bars can lose their spring, and sag, requiring more wind up.
Also, if one of the rear springs has sagged, the T-bar on that side will have to make up the difference. When setting the T-bars for the first time, I always jack up the rear under the banjo until the wheels just come up off the ground.
And it goes without saying that the front wheels and tires need to be matched.
Also be aware that as you change the ride height, the camber and toe will change and so will the track width. If the suspension is not normalized, and one side has a mobility issue, it may take more wind-up to overcome that.

But with aftermarket bars, it is possible for the bars not to be clocked the same.
I think you'd have to remove them both and lay them side by side to see that.
