Product Description

The Fluidampr 500809 is a performance viscous harmonic damper designed for Toyota 2JZ engine platforms. Unlike conventional rubber dampers that rely on fixed-frequency tuning, this unit uses an internal inertia ring suspended in silicone fluid to continuously adapt to changing engine harmonics across the entire RPM range.

This adaptive damping technology helps reduce destructive torsional vibration in high-output or modified engines, improving crankshaft longevity, bearing stability, and overall drivetrain smoothness. The CNC-machined steel housing ensures precise balance and durability under demanding conditions such as turbocharged street builds, drift setups, and racing applications.

The 500809 replaces the factory crank pulley/damper assembly and is designed for performance-focused 2JZ builds requiring improved harmonic control. Proper installation and crankshaft fitment verification are essential to ensure correct operation and long-term reliability.
