I use flex fans on all my mopars 18inch. They run cool all the time and pull a **** ton of air in it. I spin my barracuda 6k no issues.
Fear mongering? Tell that to @chryslerfat. I bet he never uses a flex fan ever again.

All I can say is he'd be dead if it hit him across the neck.i remember that...and that was terrible.Glad he wasn't hurt worse.I have a comment but i'll

But see.....that's not a flex fan you have. It's a fixed solid blade. I like the clutch, though!notice how close the mounting bolts are between the water pump and fan

I have read that the standard fan clutch turns at 75% of pump speed. An RV clutch turns at 90% if that helps youI have used new Mopar clutch fans on three different occasions but found mine were barely adequate.
Problem is they only turn about 80% shaft speed at idle in heat when you need them most. They
also have clearance problems as you have found out, are very heavy and that weight is out on the
end of the water pump shaft...not good. Lastly they fail and it is very hard to tell.
For best cooling get a new 10,000 rpm flex fan or better still 7 blade mechanical.Make sure it has
as much pitch as you can use.

What is the total height of the clutch?
