Need harmonic balancer
Looks like mine is wobbling,my belt was chirping and made me look. I don’t want a GM so what is a good aftermarket one. Motor is stock with 74,000 miles.

Dayco Powerbond PB1117N. Almost any parts house will have it.
Don't forget the ARP 234-2503 bolt. Right now they are back ordered nation wide so you will have to search for it. They are out there you just have to find one.
Good luck!

I have the powerbond sitting here and i bought a pin jig from a guy... but now i'm questioning how i want to do this...
i was going to pin through the front and use the PB1117N i have here...
but now i'm contemplating going with the summit one
https://www.summitracing.com/parts/sum-c2501/overview/
and using the ATI pin kit through the side of the snout...
Any thoughts? i'm eventually going FI but probably just staying 6 rib

Has anyone used this PB1117N Powerbond OEM-style balancer over a long period of time/miles and can comment on how it holds up? I'd rather save the money and get this Powerbond PB1117N OEM style rather than the race version if it's good enough and won't fail.

A local shop that specializes in LS motors told me this particular OEM-style Powerbond unit will fail just like the GM OEM one since it's constructed the same way (with rubber instead of being fully metal). And that there's a different Powerbond "race" balancer which won't ever fail.

I sell the PowerBonds, and they seem to be a sturdy product...if that's the way you roll, do so with confidence. 
We didn't sell PB when I did mine, or I might have gone that way instead of the ATI.
Either way, 100% improvement over the OE.

I recently went through this myself. If you're interested in a newbie's experience, one of my threads is below.

Local LS shop did the Summit SFI 8 rib on my 99 without issue. They run that balancer on all their motors. So far, so good.

right on! God to hear it. I’m looking to get my FRC relatable enough to take on an 8-9 hour road trip to see my folks and since the live about an hour from the Tip of the Dragons tail I kinda wanna check it out. I think with my Vette being close to 100k miles it’s probably a good idea to change it out first.
