It's always smart to build the "hard to get to" parts as strong as possible and let the "easy to replace" items be a fusible link....if you will.
If you decide to do it, call and talk to Bubba @ G-force and if it's in the budget, opt for the 31 spline and while it's apart do the pinion.

I spoke with them and they said they have the 27 spline in stock but the 30 is not available right now. I plan on doing the differential after the transmission is back together.
I understand it's difficult to upgrade once put together but what material is the oem main shaft? I'm upgrading to a part with identical characteristics but made from 9310 rather than what material?
Nobody seems to be able to tell me the oem main shaft material.

I broke a G Force 9310 27 spline shaft also... Honestly, I doubt its THAT much stronger then a regular T56 shaft. If anything, do the 07' C6Z 30 spline shaft upgrade, but that requires machining the pinion to receive it...
That being said, a buddy of mine just broke a stock 07 C6Z mainshaft a couple days ago on drag radials on a 1-2 shift at 590 rwhp.
I think if its gonna break, any of them are gonna break.

Now if upgrading to a 30 spline main shaft is there an off the shelf direct fit 30 spline pinion that I can order and install in my differential?
I'm looking to do a 3.90 or 4.10 gear.
Thanks
