I searched but there was so many threads I didnt want to read all of them to find this but anyway I remember someone saying that the pulleys were bad because they didnt have some kind of internal balancing device or something so was this ever confirmed?

i dont think it was ever confirmed but yea when u change the stock crank pulley it does contain an internal dampner which trys to elimante the off balance of the crank. the aem or the unorthdox pulleys do not ahve this internal dampner. in my opinion i dont think u really need the dampner bc the stock crank is ground very good and it shouldnt cause a problem.

So was it just the crank pulley that would have the problem?

the AEM kit doesn't have the crank pulley, just the power stering and the alternator. so you don't have to worry about it. i think its te SS kit from UR that has the crank pulley, but i do believe you get dampner with it, give them a call and see.
