Replacing Harmonic Balancer 2005
I am going to replace my harmonic balancer and want to be efficient while I’m doing it. I plan on procharging/supercharging eventually, so what is a smart way to do this? ATI HB, ARP Bolt, new belt. Anything else I should do while I’m down there? I don’t plan on making a crazy HP build, but I’m new to the corvette and would love some advice. 05 manual, 58k miles

I did mine not too long ago. I replaced with a powerbond HB, ARP bolt, and pinned it while I was down there Incase I wanted to supercharge someday. I also replaced seal that goes around the exposed part of the crank, it was easy. Do the belts while there as well. Only issue is removing the steering rack to get access was a giant pain but nothing was difficult from a technical standpoint. I did need a stronger impact gun than I had to remove the HB pulley bolt.

As included in the comment of post #2...if you plan to supercharge you MUST pin the HB to the crank. The C6 crank snout is not keyed and the HB is friction fit, so pin it to handle the extra load.
Let us know as you build the car and ultimately SC & tune it.
