Mini Cooper R55 R56 R58 R59 R60 Fluid Damper Harmonic Balancer SFI 18.1 it provides efficient high waterUsing only three parts a laser welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two these SFI approved Fluid dampers can control all crankshaft vibration, not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.
