Introducing the Pro Series Fluid Filled Harmonic Balancer for the MINI! We know the stock Cooper S Harmonic Balancer fails ofer time due to the deterioration of the rubber supports. This unit is a far better design, more durable, and Costs LESS than the factory replacement!
PRW Fluid Dampers are made with an internal steel intertia ring that is surrounded by a high viscosity silicone gel. The internal intertia ring "floats" in the silicone gel to combat the engine harmonics at all RPM ranges. Crankshaft and bearing life is significantly improved and safely increases torque and horsepower.
These dampers provide your engine with long lasting performance because of the silicone inside the damper will not expire and is not effected by temperature change. External balance applications feature a removable hub in order to accurately blueprint the engine and balance the assembly.
Fits the following Mini Cooper S models:
2002-2006 R53 MINI Cooper S Hatchback
2005-2008 R52 MINI Cooper S Convertible
Standard Diameter (18mm) for the Cooper S (Supercharged).
Weight = 8.45 lbs.
These SFI Certified Mini Dampers are engineered specifically for the R53 BMW-designed supercharged engine. They replicate stock 138mm diameter and WILL NOT FAIL when your engine is tuned to exceed factory performance levels. Race proven!
Include threaded bore holes to mount a crank trigger on the face of the damper, thereby allowing ignition timing to be controlled and adjusted externally.
Superior steel forgings and CNC machining ensure consistent finishes and tolerances. The fluid dampening design enhances smooth blower operation, and preserves main bearing life for engines that are tuned to perform far above factory specifications. These dampers are SFI certified to 12,500 RPM.
