Yet another ARP Cank Bolt thread

OK, I searched the archives and I think I am more confused now, than I was before ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
1. With a Lunati Crank and ARP Crank bolt, would I need to replace the crank bolt if I have to pull the pulley off for any reason? $26 vs $3 gets expensive if this needs to be done often.
2. Everyone recommends using a longer crank bolt to install the pulley, is teh ARP crank bolt longer? And is this the only one that is longer?
Thanks much,
David

The arp bolt is reusable.
The longer bolt should live in your toolbox for use only during the re-install.
And no the arp bolt is not longer. Get a longer bolt from the hardware store.

Thanks guys. That what I was thinking but I just wanted to clearify.
So, according to the parts manual, the stock crank bolt is an M16x2x103.
How much longer are we talking? and inch (~25mm) or more?
Thanks again,
David

if you use the longer bolt, and try to get it on all the way with it, the bolt bottoms out in the crank.
if you turn it hard, it jams in there, and is a royal pain to remove.
so you just need to use the longer bolt until you're ready to use the new GM bolt.
athough id just buy/make the allthread install tool... i just ordered one from someone on here..
