The ATI Super Damper is the leading solution for eliminating destructive torsional crankshaft vibrations, which is critical for high-performance diesel builds or heavy-duty towing applications. Unlike factory dampers that use a simple rubber elastomer, this 3-ring Super Damper features a patented design that functions at all RPM ranges to protect your engine's internals and maintain timing accuracy. This unit is specifically engineered for externally balanced Duramax engines and features a durable steel shell construction with a 6-groove serpentine pulley.
