AMS Performance is excited to introduce the final answer in engine dampening for the R35 GTR. The patented Engine Damper by Fluidampr© is a component that is two years in the making. AMS Performance teamed up with the original Fluidampr© to provide all R35 GTR Owners the best harmonic damper on the market. Its compact size and easier fitment leaves more room for front mount turbo systems and other custom setups. A harmonic balancer reduces destructive crankshaft torsional vibration, which is the end-to-end twisting/rebound motion, that is naturally generated during each power stroke. A harmonic balancer contributes to greater valve train and timing efficiency, plus reduces wear of critical engine components such as main bearings, oil pump, and the crankshaft itself.
