Default Can I just resurface OE flywheel???

I'm going to be helping my buddy install his new RAM PowerGRIP HD clutch in his C6. The stock clutch just isn't holding the power on slicks. We'll also be replacing the throw bearing and pilot bearing just for added insurance.

My question is, can we just have the stock flywheel resurfaced and be done with it or do we have to go with RAMs billet steel flywheel?

I've read different answers from different people, so I'd like to hear from those with experience only please.

Thanks in advance guys...

I never could find a minimum thickness spec for a camaro flywheel. Searched for a long time for it. If you are spending the money on the clutch I would pony up for the new flywheel as well.

Ya I told him the same thing but he's really on a budget and would like to save the extra $200 on the flywheel if possible. It's his daily driver and he needs the clutch swapped out asap.

NO! they are not meant to resurface. Or atleast in LS1, in my old V6 I did.

Stock flywheels can be resurfaced and I think I remember the limit is 0.015 inch for removal.

As long as it has not been cut previously you can cut .015" from the original thickness and still be ok. Removing more than this and can lead to geometry issues that lead to problems with clutch release. Let me know if you have any further questions. Thanks,

Does the flywheel have to be balanced. All the places i call say they only resurface them. Is rebalancing it that important? If so, I might need to have my buddy buy a new one if we can't find a place close by in Los Angeles.

It shouldn't need to be rebalanced. I've done two that way without a problem.

so what is the minimum thickness? I'm not sure how wide GM's tolerances were, but my uncut stocker measured anywhere from .805" to .808", depending on where I put my calipers

You can resurface the stock flywheel, but I would NOT recommend it if the clutch is made of cera-metallic material (non-organic). This material generates much more heat than the stock cast flywheel is made to handle. This is the reason that a high grade billet flywheel is needed.

understood. That still doesn't answer my question though.

The answer to your question is Yes, BUT Go with a billet flywheel. I think you would have to use the "old LS1 style" flywheel for the Ram clutch to work anyway.

TDP, Any time you reuse the stock flywheel you need to balance it with the new clutch. This is relative to the fact that GM does not balance the flywheel independent of the clutch assembly. This means that it is not "0" on its own. There have been countless threads relative to folks having to pull parts and balance then after non doing it the first time, when using a stock flywheel and aftermarket clutch.

Spootnik, The stock flywheel would normally be ~.810" thick when new. I hope that helps. Let me know if you all have any further questions. Thanks,

I have never had to balance any clutch with a stock flywheel and I have installed a LOT of clutches. The only time I've seen a problem is when a stock fly gets cut too thin, then overheats and warps. Well now you are going to make me go check, haha. I would have to see it to believe it anyway.

I am not saying that folks don't get lucky but the OE flywheel isn't balanced on its own. Your call of course...but I always suggest having the old flywheel and new clutch balanced together.

I did that with mine and was told countless times that the LS1 clutch/flywheel couldn't be balanced - i guess i will be a member of the countless threads, cause my **** ain't right -

I can balance these for you if you are interested? Just give me a call and I can issue an RMA to get this set-up. Thanks,
