ARP Crank Bolt Specs.
Ok. I did find this thread here at www.ls1tech.com/forums/archive/index/php/t-339001.html. I think this guy says the box his ARP bolt came in has the spec at 190 ft lb. Check it and make sure.
I found this here on this site but don't know how to get it to you other than copy and paste.
I have an ARP balancer bolt. It's a little longer and much better quality than the stock bolt. It has been on my car for over a year and hasn't given me any problems. The install procedure is different than the one for the stock bolt. The ARP bolt is not a torque to yield bolt, therefore unlike the stock bolt, it can be reused. Once the balancer is seated using the old stock bolt (torqued to 240 lb-ft), then remove the stock bolt, apply ARP moly lube to the threads and washer surface of the ARP bolt, then install and torque to 196 lb-ft. This torque is also the same if using blue loc tite. If you use SAE 30W oil on the threads, then tighten to a torque of 247 lb-ft. These torque recommendations were told to me by ARP when I installed mine.

The packaging the bolt I have came in doesn't have the torque specs. This sucks. I need to be 100% sure that it is 190 ft lbs, so I don't lose another ASP pulley....
