Default Harmonic Balancer Problems

Ok, so I know that there are problems with the Harmonic Balancer Bolt not staying tight despite the tremendous amount of torque... I also am aware of the rubber seal coming apart around the edge..

GM has replaced my Harmonic Balancer 3 times in the past 2 months...So this is clearly something that needs a solution...

What EXACTLY do I need to do?? GM says they'll pay for it because they installed the part.

How do I prevent this from happening again??!?! I want this Harmonic Balancer Bullsh*t to finally be fixed!

Thanks for your help, Sammy

The harmonic balancer is an issue on all Corvettes, including the C6's. One permanent fix is to go with a billet balancer. We use ATI -

We have installed these on some pretty powerful cars, including a 660 rwhp C6 Z06 S/C and our Texas Mile car that went 199.8 mph - a TT Z06 (made 860 rwhp) with no problems.

Which one would be best suited for daily use? The "Street" one I assume...? And what size? 6" or 7"?

Since the LSx engines use a serpentine system, I would use the Serpentine model. They aren't especially inexpensive, but they are excellent quality - and you'll never have to do it again - even if you wind up modifying your engine or going to forced induction.

Pay once and you're done.

I don't understand that website... But I do understand that I need a Serpentine model.. Obviously.. I just don't know exactly which one to order. Also, how do I know that this will fix my problem??? Yes, the harmonic balancers are horribly designed. BUT, WHO THE HELL GOES THRU 3 HARMONIC BALANCERS in 2 MONTHS???????? There has to be something else causing this, don't you think????

before I go spending more money on this thing. I want to make sure that I am FIXING the REAL PROBLEM.

Could the problem be with the crank it self ? might be out of balance or something.
