For those with Superior engines (like me - we have one on our Tundra), if you;re wondering about the affected range of cranks, I checked with the company, and it appears that the cranks in the AD were from the 2012 - 2014 timeframe. Ours was from back in 2004, so we’re clear. This might help with the angst...at least for those with older or younger cranks!
