I haven't contacted JustSuspension (yet).
Being overseas, US warranty stuff still always costs money somehow, especially with heavy & bulky parts.
But then again, I don't feel the need to pull a warranty card since the purchase was 'just' over one year, nor have I a grudge against JS.
Defects can happen, and I was already contemplating another torsion bar upgrade to either 1.06 or 1.12". I think I'm pretty much set on a set of 1.12" FirmFeel bars, although 1.06's would be fine as well I think.

I would be nice if they would send me a new bar ofcourse.

Just an hour ago I took some more pics after I cleaned the broken end of the bar. Shown below;


Here are a few images showing the broken piece with a little more detail;

Interesting to notice is that the crack, or open space seems to run into the hex part.
And you can barely see a marking on the outside of the hex flat.
