I've seen water pumps advertised with a hardened pulley, should I get the hardened or the regular? Other than the obvious of less pulley wear, is there any special reason for the hardened one? Thanks.

 

[tacoma]

besides the obvious?

Probably not.

there all the same my friend

Sometimes Chinese made parts are case hardened to make up for crapola metallurgy. Quality steel wouldn't require case or any other hardening. I'd find out where they're made.

If they are all the same why does the same vendor advertise hardened and regular? Probably doesn't matter much one way or the other.

The key word is probably 'vendor'. That's far different from manufacturer.
