$100 SHIPPED...usually $160 plus shipping. Below picture from Coz's site, but mine are exactly the same.
ATI Harmonic Damper.
The best damper sold out their for our cars. If you want the best build, you need the best pulley. I have a spare one of these laying around here and don't need it. This one has a two tiny notches on it. These notches are very tiny, and I have confirmation from ATI that this does not affect the pulley in any way at all. Beleve me...they are just minorly supefical and affect nothing. This is the perfect pulley for you.
This is the race one that is good for up to 1000HP. New they are $510 + shipping usually. This one has never been driven with, but was installed and removed only once. Price is $410 SHIPPED.
