Harmonic vibration damper for the crankshaft suitable for all 4.0L Biturbo EA825 engines such as the Audi RS6, Q8 or Lamborghini Urus.
Standard dampers only have a rubber compound which is ONLY designed for a standard engine and quickly reaches its limits in performance-enhanced vehicles.
Especially with tuned engines, where a different crankshaft, piston or conrods are installed, the standard damper should be replaced by ours.
Otherwise, there is a risk of the crankshaft breaking at high engine speeds!
The harmonic vibration damper has a GEL filling and eliminates ALL negative vibrations that occur on the entire crankshaft drive across the entire speed range!
Further advantages:
We successfully drive the vibration damper in our Lamborghini Urus test.
Average rating of 0 out of 5 stars
Achieve over 1,000 hp with the SQ7, SQ8, RS Q8 and URUS!
Certainly over 1,000 hp with the RS6 / RS7 C8!
