can this be used on the 3.6 or any engine that didnt come dampended from the factory?

Yes

New pulley and belt arrived Monday. Included bolt to remove OEM pully and tool to install new pulley. Beautifully made.

Thanks Mike

Thanks for the kind remarks, Enjoy!

How much smaller than stock?

16hm from a pulley? hmmm...

Wunderbar. Keen on this. Was going to order #601 but assume this would be the superior part and if I wanted to changed over the a LWFW later this year, this would be the right part for me, right? I'm a 997.1 standard 3,6l car.

Correct :)

The 608 Damped Pulley would be the better choice with lightweight flywheel.

BACK IN STOCK!
