Factory LS1/LS6 clutch info? I am trying to determine the correct component part numbers that comprise the factory flywheel/clutch disc/pressure plate assemblies for the LS1 and LS6.
It seems that 12570281 was the original 01-02 LS1 assembly. That appears to include the 12570280 clutch disc and 12562770 pressure plate.
According to GM, 12570281 has been superseded by 12581650, which is now the new 01-02 LS1 part number. Can anyone that has purchased 12581650 confirm the clutch disc and pressure plate part numbers?
I believe it’s well understood that the Z06/LS6 assembly, 12570806, has a pressure plate with stronger clamping load capacity, but the clutch disc is the same. Can anyone confirm that clutch disc and pressure plate part numbers?
And last, does anyone have the clutch disc and pressure plate part number for the 98-00 LS1 assembly, 12562765?
I would be interested in flywheel data too. Is the Z06/LS6 flywheel any lighter than the LS1 flywheel?
Thanks!
