Well I know Romac is a real good balancer and it's a good price but it doesn't say the thickness so I'm not sure. That's my main concern cause I have a new March serpentine system and don't want any problems mounting it up. Next weekend is the Indy swap meet and I'm going with my tape measure and see what I can find. Thanks Demon
The Romac is a good damper. E-mail the seller and ask for measurements. Otherwise if you don't race your car, just install an OEM damper. They are usually tested at somewhere around 8000 rpms. Hope you find one either way.
