FLUIDAMPR PERFORMANCE DIESEL DAMPER 830151 | 2020-2023 6.6L DURAMAX L5P

Reduce harmful crankshaft torsional vibration in your 2020–2023 GM 6.6L Duramax L5P with the Fluidampr 830151 Performance Diesel Series Damper. Designed for stock, work, towing, performance, and competition applications, this viscous crankshaft damper provides broad-range vibration control to help protect critical engine components throughout the operating RPM range.

Fluidampr uses viscous damping technology to automatically respond to changing torsional vibration frequencies as engine speed, load, and configuration change. This helps reduce vibration-related stress and wear on the crankshaft, main bearings, valvetrain, and other critical components without requiring the damper to be rebuilt or retuned as engine modifications are added.

The 830151 features precision CNC-machined and computer-balanced components along with a removable hard-coat anodized aluminum fan pulley. A mandrel-drive provision and pre-drilled 3/8"-24 mounting hole on a 3.200-inch bolt circle provide additional flexibility for compatible performance accessories. The updated design also allows serpentine belt replacement without removing the damper.

Manufactured in the USA, the Fluidampr 830151 features a corrosion-resistant finish with engraved markings and is built to SFI 18.1 specifications for competition use.
