I bought the AEM underdrive pulley kit and haven't put it in yet because i was waiting on a crank pulley. I now have the crank and need the belt for it. What belt/part numbers do i need for the crank?

 

I would assume that you can make enough of an adjustment to get the pulley AEM sent to work... if you need something smaller I'd just go to an autoparts store and match the belt to something in a smaller diameter and use that.... Who did you get the crank pulley from?

also...i heard that changing my pulleys with mess with my car. my guy friends insist that my car will run horribly. any help??

 

I'm going to assume that you have AEM Tru-Power pulleys which are the stock size and not underdrive.... The crank pulley may be undersized or not who knows..... the only concerns you really have are the charging system and A/C.... There is a possibility that those may not be getting enough juice but I doubt it.... Unless you are changing the diameter of the pullies by a fairly large amount then I wouldn't worry about anything

 

Yes, I do have the AEM Tru-Power pulley kit.

Thanks for everything!

 

Side note: if you are going to do the work yourself and have never done it before be aware that the crank pulley bolt is about the most frustrating bolt there is and sucks to take off unless you have good power tools.... do some reading on it first if you need help
