I wanna know what eveyone thinks about the those n1 crank pulleys you find online all the time, anyone has had any trouble wit them?

 

If you only have an alternator, and like the idea, buy one, if you don't, then don't.

All you'll get in replies will be it caused problems, and the other half is it works fine.
Every thread/question about them has been like that on here, so it's just up to you if you want one.
