Looking for a race quality non fluid dampener

How are they on there thickness? I will need to get a new balancer for a couple of race mills in the works and the pulley alignment can be a PIA when the damper is thicker.

I’m working on a 318 & 2-340’s.

I have a 5” aluminum crank pulley and had to make a spacer to align it with the wp pulley. I can measure to the belt off the balancer if you need it.
