only problem i have had with mine is the great power out put and the increased roost from all of the torque. I did have mine balanced and it feels so close to stock its crazy but it turns up quicker bc of the shorter rod
If you have actual personal knowledge of an engine that failed as a direct result of the use of a HR HD or +3 crank,then buy all means post it up....but....please refrain from using blanket statements or using third party heresay regarding this subject.
I recently started a similar thread and there were quite a few responses and to my knowledge...there have not been any reports of durability issues of failures due to the HR cranks.
The only failures I am aware of are the ones that combined a big bore/stroker combo....and it was the cylinders that failed...not the crankshaft.That is not to suggest the cylinders are at fault...in some instances...builder error or other parts failure could be a factor.

What he said.
I have not yet seen the crank as the issue.
I am still going strong on mine with the Athena 98mm jug. So far, so good.
But I don't have huge hours on it yet either.
I did not balance, but I wish I would have. It will just add longevity to the whole build.
