Mainly used in drag racing high rpm applications. For racing applications only. It does not have provisions for pulleys.
This damper utilizes an ATI 7" Race damper attached by a custom hub. This is for dry sump applications only as the custom hub takes up the space of oil pump collar. By doing so, this allows more hub engagement on the crank. At high boost and high rpm, 4 cylinders vibrate tremendously. This setup reduces the vibrations.
Our dry sump hub does bolt to the front of this pulley. The OEM timing pin on the front cover needs to be removed for this pulley and will not line up.
Picture shows dry sump hub attached but is not included.
