So I am getting the dreaded harmonic balancer wobble and squeal. So...time to replace, but with what?

I cannot afford the ATI or Fluidampr @ ~$400. So...thoughts on any of the below:

2. http://www.summitracing.com/parts/su.../make/cadillac

3. http://www.summitracing.com/parts/rn.../make/cadillac

Id just throw another stocker on there honestly.

Buy an ATI harmonic balancer or go stock. Everything else is just a pulley.

Dorman looks like crap just like the stocker. I have the summit racing one, it's solid.
I'd never do a stock one again.

Doesn't Summit also make a low buck OD balancer for the LS6?

Not sure, I went with standard diameter. Noo way I would trust the stock one for a blower. Mine seperated taking out both belts and my MAF wiring in the process without much warning. Could have been worse, much worse. Like the outter ring flying off at 6500 rpm.

What part number did you replace it with Tommy? not an underdrive one I take it?

Did you notice it smoother with the summit one?

Lookin at changin mine as well. Going to have to repin the new one.

Can't remember the part number, but I looked up the C6 Corvette with Ls2, has the same spacing. With A/c, it's listed as a 8 rib but works as an 6 rib.
Smooth as butter, no wobble. I always figure if I'm going to replace may as well upgrade. I would have went with ATI but had already spent a small fortune on my car at the time, just wasn't in the funds.
The summint one fit the bill.

Stock and ARP bolt, I got brand new OEM from e-bay when I did my oil pump, cam swap for $80 and couldn't be happier, ARP Bolt is worth avoiding future back out headaches IMHO.

EDIT:

Ouch looks like your LS2 verion is slightly more expensive, Part number 12635652

im thinking either ATI or powerbond sfi seems like good options.

Powerbond SFI looks like a good unit.

I've got a Powerbond 25% UD.. 1/2 the price of the ATI

Does powerbond make a stock size pulley?

I believe the non underdrive is PB1117SS. I'm leaning this way right now too as it seems like a good cost/quality balance.

Sometimes i hate forums... I've been reading over in corvette land about non stock/non ATI balancers and timing chain failures. My car get a fair deal of autox and the occasional track day, but it has me debating my options now.:

I also found professional products 80033 that is a 7.5 ls6 says for corvettes

running a power bond stock size sfi one here as well. Good balancer for the money.
