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).
Also available with VMP 5% or 15% overdrive pulley ring on second shiv. As part of VMP's 8-rib conversion system for the coyote, they've designed an overdrive pulley that bolts in place of the "AC pulley" on the ATI balancer. These positive displacement supercharger systems use the rear shiv for best possible crank loading, a 5% OD is the largest size possible due to the first shiv tensioner on the front cover. The 15% OD ring requires our low-profile accessory tensioner.
NOTES: Most pulleys/dampers require additional supporting parts. Contact MPT's Tech Support for addition information or questions.
