Enhance the performance and longevity of your LS-based engine with the Fluidampr Performance Damper (Part #740121)—engineered for 1997–2013 Chevy Corvette, 2004–2007 Cadillac CTS-V, and 2008–2009 Pontiac G8 models. Stock rubber dampers deteriorate over time, allowing harmful crankshaft torsional vibrations to develop, especially under high-performance conditions. Installing a Fluidampr viscous damper helps reduce these vibrations, extending the life of main bearings, timing components, and crankshafts while improving valvetrain stability and accuracy.

Unlike traditional rubber-based dampers, Fluidampr automatically adapts to engine modifications and continuously self-tunes in real time across the entire RPM range. Each unit is CNC-machined, computer balanced, and maintenance-free, providing long-lasting reliability for both stock and modified engines.

Note: Not compatible with supercharged applications.
