This is not only a direct replacement for a failed crankshaft pulley, but it's also an upgrade. This ATI super damper is a few pounds lighter than the stock damper pulley so your engine will rev faster. But it is also an inertia damper so it has a weight in it that moves to balance the engine which will balance much better than the stock chunk of rubber the stock one has.
Will ONLY fit MINI Cooper S supercharged engine with W11 engine, does NOT fit any other engines or model MINI.
Fits:
2002-2006 R53 MINI Cooper S
2005-2008 R52 MINI Cooper S Convertible
2006 R53 MINI Cooper S John Cooper Works GP
The included install bolt is longer than stock with a washer that will allow you to press it on about half way, then you can use the stock bolt to press it on the rest.
This is the only crankshaft harmonic balancer damper replacement we use in our shop as we never recommend the Alta, M7, Kavs, or Cravenspeed lightweight pulleys as they can damage the engine bearings and oil pumps.
