Hi Guys,
I noticed that my crank pulley is vibrating. I would like to replace it with an aftermarket stock sized crank pulley. Which shops sell these? can you please provide a link to it?
What else should I change while I'm changing the crank pulley?
ac belt
main drive belt
ac belt tensioner
main drive belt tensioner
arp crank pulley bolt
car is an '02 Z06 with 50k miles
how much would a shop charge to change these parts? I'm pretty close to The LAPD.
Replace it with an ATI super damper. You will never have trouble again. This is an excellent product 100 times more advanced than the GM version. http://www.atiracing.com/fallsale/fs_damper.htm
Labor varies shop to shop. But it should take about 5 hrs. for a tech that has done this before. Right tools and lift it is not difficult.
Good Luck!

one more question:
I noticed it only vibrates at idle, it goes away when I rev it.
should I worry about it and change it ASAP?
I don't want to spend the money to change it if I don't have to.
It doesn't go away, the harmonics change with the rpm and the dynamics change. However the vibrations will wreck an engine. Go to the ATI web site and research the FAQ and tech articles. Information is power.
