And you'll never have to replace the crank bolt again, just keep reusing it every time you remove it for any reason.
And it won't come loose because of the pin there can be no relalitive motion between the crank and the balancer.

Ideally the crank should be machined for a woodrif key and so should the balancer.
I used the ATI balancer with a steel hub and dual pinned it with the ATI kit that uses 2- 3/16 hardened steel dowels perpendicular to the centerline of the crank.
It's more work and more money but the peace of mind is worth it in the long run. JMHO
