FLUIDAMPR PERFORMANCE DIESEL SERIES DAMPER 830111 | 2006-2010 6.6L DURAMAX LLY/LBZ/LMM

Reduce harmful crankshaft torsional vibration in your 2006–2010 GM 6.6L Duramax with the Fluidampr 830111 Performance Diesel Series Damper. Designed for LLY, LBZ, and LMM applications, this viscous crankshaft damper provides broad-range vibration control for stock, work, towing, performance, and competition-built trucks.

Fluidampr uses viscous damping technology to automatically respond to changing torsional vibration frequencies throughout the engine's operating range. This allows the damper to accommodate changes in engine speed and configuration without requiring rebuilding or retuning, helping reduce stress and wear on the crankshaft, main bearings, valvetrain, and other critical engine components.

Precision CNC-machined and computer-balanced steel components provide accurate operation, while engraved markings and a corrosion-resistant black zinc finish provide durability and serviceability. The updated design also allows serpentine belt replacement without removing the damper. Manufactured in the USA, the Fluidampr 830111 is built to SFI 18.1 specifications for competition use.
