the hub adapter is machined with the same precision that would be required of making a completely new pulley. it is located and datum'd off of precision machined faces so alignment is not an issue. its a simple and cost effective solution with no real penalties.

also, we are not advocates of replacing the factory damped crank pulley with with non-dampened aluminum replacements that do a poor job of neutralizing harmonics in the crankshaft.
