Isolate harmonics before they can destroy your engine.

If your engine build is plagued with broken crankshafts and oil pumps, the cause may be a mystery to you as it has been to many. Controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive.

The truth is, harmonics can destroy these motors despite their ideal balance.
ATI Performance Products, a leader in Harmonic Dampers has developed two new dampers (Part # 917994 & 917994TR) for the popular S54 & S50b32 Euro, as well as the 3 liter S50b30 Euro.

These dampers are made available exclusively through VAC, and they nearly eliminate all unstable crankshaft harmonic-vibration, allowing the engine to produce more horsepower and torque, maintain reliability, and reducing internal engine wear at the same time.

A trigger wheel comes standard on M3 Damper (Part # 917994TR) needed for M3 euro engines.

When used with the included pulley, they allow a direct replacement fit over the OEM balancer. Available in underdriven , overdriven or standard diameters . Also, configurations available for use with our dry sump kits. Both dampers have a 7" outer diameter and include OEM style timing alignment tabs.
