I'm installing a new Edelbrock supercharger in my 2009 GMC Sierra Denali with the 6.2L L9H engine. I am pinning the crank and installing an ARP harmonic balancer bolt #234-2503 instead of another stock one. I would like to clean out the thread well before installing the new bolt so I'm looking for a thread chaser to do the job. Does anyone know what size thread chaser is required for this? I read somewhere it was a M16 x 2.0. Is that right? And if so, where can I find one? I've looked online with no luck. Also, any place I can find a strong 1-1/16 socket to install the bolt with? I have a couple of Craftsman that size but I'm not sure they will hold up to 235 ft. lbs.

Any help would be appreciated...thanks.

Just get a tap.

Thanks MikeGyver.

I'll just use a tap to clean it. I did confirm the size is M16 x 2.0.

I also picked up a Snap-On 1-1/16 12 point socket. That should hold up to 235 ft. lbs.
