[quote=+fireamx]1957 was the big change over year for Chrysler, with the "Forward Look" styling and all. It was also the first year for their controversial Torsion Bar suspension.
I never really did hear what the actual problem was, (I'm assuming it was because the 1st. batch of bars must have been too hard or brittle) but there were all kinds of horror stories about them breaking. Most of the time though it happened while the car was sitting in the garage, and usually to a Plymouth. (which I couldn't figure out since they all used the same bar I think.

Although I wasn't around in 1957 and I know many things changed by the time I was part of the Chassis Department in about 1968, but at that time there were many different torsion bars for various products. There was no difference between a Plymouth, Dodge or Chrysler excepting some were more heavy duty than others. Of course the usage was based on the overall car, but the brand name had nothing to do with it. Maybe the problems in 1957 told them that a "one size fits all" torsion bar didn't work. The main problem I remember with the torsion bars were what we called Flat Torsion Bars. However flat torsion bars could not get installed because the hex didn't match so they couldn't be pounded in.
