Product Description

The 720361 targets a real weak point in high-performance Gen III HEMI builds: as cylinder pressure, RPM, and rotating assembly weight climb with modifications, the factory elastomer damper loses effectiveness at controlling crankshaft torsional vibration. Fluidampr's viscous damping technology holds up across the full RPM range instead, protecting the crank and accessory drive components under sustained high-performance use.

The removable 6-rib pulley includes a dry sump mandrel mounting provision, giving racers a path to competition-style oiling upgrades down the road without swapping the whole damper. Independent testing backs up the design too - an average 8% reduction in torsional vibration over a stock elastomer damper in side-by-side Raceshop testing.
