OEM dampers are optimally tuned to a narrow band of "perceived normal driving conditions" and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges especially during competition use.
