Default Dry sump drive pully issue, help

So I got the dry sump system from John at AVIAID and was half way through installing it on my LS2 install and I have an issue. The new crank shaft damper and dry sump drive pully has a 1.34" longer stack that the crankshaft bolt needs to pull down than the LS2. The LS2 bolt is 4.000" long, the LS6 bolt is 4.875" long, both are too short to make this work. I need a bolt 5.340" long. Does anyone have a source for this special bolt? I called Dave at AVIAID and he was no help. (

Default Crank Bolt

That's an easy fix...just call ARP tomorrow and give them the length you need. They make custom length bolts all of the time. Great guys to work with...

You need a longer crank bolt?

I ran into this on an LS engine with external sump etc.
bought a bolt from Mcmaster-carr 16mm x 2.00 grade 10.9, 140mm from under head to end of bolt, stole a washer from an LS7 crank bolt.

ATI stocks the bolt and washer you need.
