Keep your bearings and oil pump happy with this Super Damper.
We've found that really high horsepower MX-5s - over 280 hp - have been overwhelming the stock harmonic damper. This can crack the gears on the oil pump as well as damage the bearings from the hammering, not to mention the sudden lack of oil pressure and tooth fragments will destroy the rest of your engine. Don't let this happen to you! ATI developed this replacement damper to solve the problem.
This unit replaces the stock damper with what is essentially two in one. The result is not only a safer engine but one that runs more smoothly all the time thanks to the improved vibration absorption.
