Innovators West crank dampers. The damper listed here has a cog drive provision and is the damper used to convert to East Coast Supercharging's direct drive setup; it is offered in 10% or 15% overdrive, and it already comes with the ECS direct drive system, so it is sold separately for owners who need the damper on its own.

What a crank damper does and how overdrive pulleys raise supercharger speed: what does a harmonic balancer do? Kits by platform: supercharger kits.
