Enhance the performance and reliability of your 1990–2005 Toyota or Lexus 1JZ / 2JZ engine with the Fluidampr Performance Damper – 15% Underdrive (Part #840811). Designed to replace and outperform traditional stock dampers, the Fluidampr viscous damper effectively reduces harmful crankshaft torsional vibrations that can cause wear on main bearings, timing components, and crankshafts—especially in modified or high-performance builds.

Unlike rubber-based dampers, Fluidampr automatically adapts to any engine modifications and continuously self-tunes in real time throughout the entire RPM range. Each unit is precision CNC-machined, computer balanced, and features a steel damper body with a hard coat anodized aluminum pulley for strength, accuracy, and durability. This 15% underdrive configuration reduces accessory load for improved efficiency and throttle response.
