The PRO/RACE "ALL STEEL" Harmonic Dampers are designed and manufactured for racing and high performance street applications and are available for a wide range of engines. The PRO/RACE Damper is a direct replacement for the cast iron stock damper which is no longer permitted by most racing sanctioning bodies due to the danger of fracture and high speed disintegration or separation of the inertia ring from the hub. This problem is eliminated with a PRO/RACE Damper. The PRO/RACE "ALL STEEL" Harmonic Damper is also a must for all belt driven supercharger applications due to the additional torque loads on the damper hub and keyway which results in failure in nearly 100% of all blower installations with a stock damper.


Key Features:

  • "ALL STEEL" construction
  • Exceeds SFI Spec. 18.1 - Spin tested to 18,000RPM
  • Specially formulated bonded elastomer
  • 100% CNC machined
  • Billet steel splined inertia ring and hub
  • 60° of engraved timing marks (40° on SB Ford models)
  • Easily installed - Instructions included
  • Bonding on "Race" models only.


    Exceeds SFI Specification #18.1
    This specification is enforced by most racing sanctioning bodies to assure that the dampers conform to specified standards. While the SFI test is quite stringent and requires the damper to be spin tested at a speed of 12,000 rpm for a period of one hour, the PRO/RACE Damper has been tested at a speed of 18,000 rpm, substantially exceeding SFI requirements.
