ARP always has great quality.
It worked on my built LS3 with Romac balancer. The washer was too big for my balancer though but it still worked.

bolt requires 1-1/16 12 point socket, torque wrench rated for 235 ftlbs. none of that angle over bs
if you are looking for a bolt that you don't need that angle over crap to use, this is the one! Even better than that since you are not trying to stretch this bolt its reusable! This bolt requires 1-1/16 12 point socket and a torque wrench rated for 235 ftlbs.

The best and worth the extra cost
The media could not be loaded. This bolt can be reused while the OEM cannot be re-torqued.
