If these are the same bars I have they should Not have been adjusted up to stock ride height! They are designed for a lower than stock ride height.this may not have caused the failure but I would imagine it definitely contributed to it.these larger than stock bars are of course much stiffer and are not able to twist like a factory bar.if one cranked it up to stock ride height the bar will not have much give left in it and will transfer more force to the crossmember.just my .02C.
