Just going off this parts page 09 says “with supercharger” i.e. ZR1 & 08 says “without supercharger”. I replaced my failed mc with the 09 part #.

I believe this is correct. I know 2006 calls for the 08 part number and that’s what I have. I can upload pics if need be. I just got it in the mail a few days ago

I decided to be pro active and replace mine rather than always wonder if and when I'd get stuck. I just got the part from a GM dealer online and was surprised to find that it was full of fluid. It looks like it is brand new and there are no signs it had been installed, but are these normally shipped filled with fluid? I have never had a part like this come new with fluid already in it.

Yes they are pre-filled. I submitted a reimbursement claim for the cost of the part & GM issued me a check for the full amount.

Zr1 comes back 19331708 at my dealer and by vin. What is the difference in the two numbers? Dealer says 19331709 is different and won’t work.

Anyone know what the deal is with the two part numbers?

19331709 comes backs as “with supercharger”, i.e. ZR1. And 1708 says “without supercharger”.

I had the clutch master cylinder replaced on my '08 Z51 M6 2 years ago with 19331709, no fitment issues reported. I also had them keep and re use the original translucent reservoir for easy fluid inspection.
