The patented ATI Super Damper is the only damper designed exclusively for high performance Ford engines.
Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. This inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application).
NOTES: Most pulleys/dampers require additional supporting parts. Contact MPT's Tech Support for addition information or questions.
