SFI 18.1 Harmonic Balancer for Chevy ZL1 Camaro. The damper was designed with an adapter plate that accepts the interchangeable crank pulleys available directly from Metco Motorsports & Lightning Force Performance.
Both companies offers a smaller diameter idler pulley that will allow for even bigger crank pulley sizes for increased boost. Picture shown with Metco Motorsports crank pulley installed. Pulley is not supplied by Innovators West and must be purchased directly from Metco Motorsports or Lighting Force Performance.
