Race/ slant 6 torsion bars

From what I recall...... I thought I heard the MP .840 bars didn’t hold up well at all.

Sort of like when my friend was using the Moroso drag race front springs in his GTO.
It was basically a new set every season.

He figured out that 1/2 the wear and tear was the car bobbing up and down when it was traveling in the trailer.
He ended making a “ramp” that the front cross member would ride up on when the car was loaded into the trailer, which immobilized the front end in an elevated position.
Then it was a set of springs every other year.

They didn’t break...... they just lost their tension and the car would leave well anymore.
That’s what I remember the story being for the .840 bars as well.
They go flat.
