Clutch Pressure Plate Bolts

Hi Jerry,

Once again you are a wealth of information and are always looking out for others. After wrestling with my bellhousing due to previous owner putting permanent loctite on it; I could not bust some of the bolts with impact either so on my back with foot holding beaker bar, I needed two arms to bust the bolts.

Anyway, getting back to the pressure plate bolts and your information it appears I need the LT1/LT4 bolts. Any part numbers available? If not, I should be able to call the dealer with the year, make, model to get it.

I am replacing the stock dual mass (what a heavy SOB) with Fidanza aluminum (bought from a fellow ZR-1 owner) that came with the ARP bolts it appears, but did not come with the oversized ground washers that SRP sells. It would not matter as it won't work for the Fidanza 3.2 clutch set up that I bought that came with the thinner pressure place as shown.


Valeo pressure plate that came with Fidanza 3.2 clutch kit. Stock bolt compared with longer ARP (minus washer)


Stock pressure plate with stock bolt compared with ARP (minus washer)

The Fidanza flywheel that I bought from fellow member was installed it appears, but not used and the bolt holes are tapped out and it came with a tap and I can tread them in quite deep but the bolts are still way too long. I guess worst case scenario is to use the stock pressure plate.

What are the effects of going with the thinner pressure plates?


Thanks again for the info.
