What is the size of a stock crank bolt?
What is the size of a stock crank bolt? I need to know the actual thread size and length of the stock crank bolt so that I can get an extra bolt that is 1 to 2 inches longer to help in the removal and installation of the crank pulley on my LS1 Trans Am.
are you re-installing the stock pulley? That's the only reason you would need a longer bolt.
A standard 3 jaw puller will take the stock pulley off, and a standard three bolt harmonic balancer or "pulley" puller will take off the ASP or simular pulley.

Yes. I already put my stock pulley back on and it was a PITA. This is why I want a longer bolt. Also It will help to take off my ASP pulley just so I am not at the end of the threads on the crank(safer).
time to
the asp pulley. It's 16mmx2mm pitch, stock length is just under 3". So probably about 75mm length.
I run a longer bolt due to my ATI hub have an inch longer shoulder inside the hub.
You can get a bolt of the same alloy from Mcmaster Carr for about $3 plus shipping, but you'll need to find a large diameter hardened washer if you want to use it as the crank bolt all the time.
They have them up to 140mm length
