Fluidampr Harmonic Balancer Internally Balanced Damper for 2JZ Toyota Supra (840801) SpoolinUp The Recirculated IS1890P is legalFluidampr Engine Dampers mitigate destructive vibrations transmitted through the crankshaft by controlling torsional vibrations. These vibrations, caused by torque spikes during combustion, can damage engine components. Unlike stock rubber dampers, Fluidampr dampers work across a broader range of frequencies, crucial for engines with modified components. Rubber dampers are frequency sensitive and may fail when engine dynamics change. Additionally,
