Whats the benefits of changing torsion bars

Mattax said

Not really true because springs can be projected for nearly infinate life within the elastic limit. Torsion bars don't exceed the yield point therefore will not normally fail simply due to use. Leaf and coil spings can exceed the yield point and therefore potentially can fail due near stress risers. A torsion bar with a stress riser like a cut or chip is in the same boat.

Springs get older and weaker with age and duty cycles. Period!

There are no "wonder springs" that last forever. Everything fatigues and gets weaker. This is why rear leaf springs sag with age.

We had many broken torsion bars at the shop where I was a mechanic in college where they had broken. They were used to do front end inspections and look for loose parts before being aligned. A torsion bar is just a bar of steel used as a spring.


If YOU choose to run original springs and torsion bars, that is YOUR call.

I however, choose to replace MY 40 - 50 year old springs and torsion bars on MY car....

If you believe that the used parts are still good, I would be happy to sell you my junk when I am done with it.... :D
