The Fluidampr viscous damper will reduce wear on your engine’s main bearings and timing gear. Therefore achieving more accurate valvetrain operation and lower the risk of crank failure.
Completely unlike the rubber based dampers, this will automatically adapt to your modifications. It will then continuously self-tune in real time, as the engine revs up, torsional vibration suspends the inertia ring and reduces its weight felt on the crankshaft. Measured as rotating weight, this effect helps maintain quick revs while preserving optimum damping.
Benefits:
- Helps reduce harmful crankshaft torsional vibration.
- Decreased "Clutch/Gear Box Chatter" which is caused by lightweight single mass flywheels.
- Reduction in rpm drops when shifting in a competitive environment.
- Gains of 3-10whp and 5-13ft/lbs. torque depending on your current setup.
- An overall more efficient and reliable engine.
Features:
- Black Zinc Finish
- Reduces Harmful Engine Vibrations
- Never Needs To Be Rebuilt Or Tuned
