Torsion bars Options

[Cvrguy]

Just pulled mine out of my '73 today as I'm replacing the suspension bushings. Both bars are slightly abraded due to the very old bushings deforming (old? I hardly had to heat the retainers in order to get them off!). Replace or not? Mine measure a little over 18mm at the shaft (18.01 and 18.25mm to be precise. The difference may be in the amount of paint on the bars). I've checked the usual sources but no luck as yet. Who might carry them? I really don't want to increase the spring rate with the 20mm ones from Pelican.

If I clean these up, are they useable? Can they be reversed? Does the minor abrasion significantly change the spring rate? Are those from the early 911 of that era an alternative?

While i'm at it, one of the adjuster screws shows signs of starting to split. Replace?

Damage like that to torsion bars creates stress risers. Bar will eventually break at an inconvenient time.

Same on the bad adjuster screw which is already showing major cracks.

You need new LCA bushings or you’ll just damage the new bars. Highly recommend Elephant Racing for new rubber bushings. They are sized properly. Many other suppliers parts aren’t.

You can source the torsion bars via Elephant Racing.

Note: it looks like Sway A Way has been through some changes recently with acquisitions, moving production to Mexico, and rebranding to X-sway.

I would try to get older Sway A Way parts that someone like Elephant or Sierra Madre may have in stock vs being the guinea pig for the new products from X-sway until we know more about all the changes and how that may be affecting parts quality.
