Dime

Alright, my old mans c5 needs to have the harmonic balancer replaced. We've decided to go the ATI, ARP route.

The cars completely stock, what's the correct part number to replace the OEM balancer with an ATI?

Thanks

ATI 917266 is the one you want for the stock diameter with the steel hub and aluminum shell while retaining AC.

ATI 917278 is the 10% underdrive pulley with steel hub and aluminum shell. I would recommend this one for a slight power increase and less rotational inertia. Also costs less.

Brian Tooley has the best prices I've seen. I've bought a ton of stuff there.
