The Fluidampr Harmonic Damper Pulley For Mazda MX-5 NA NB is designed to replace your standard damper. The pulley that came with your car actually dampens harmonic vibrations generated by the engine, and as more power is added it becomes less effective. It’s recommended that when horsepower is increased significantly that the damper is upgraded to reduce wear on main bearings and timing gear.
Features a 10% underdriven Waterpump Pulley (Stops caviataion of the coolant at high RPMs)
If you’ve purchased one of our Turbo Kits, this is excellent insurance against the oil pump gears failing as well as balancing out the engine during operation.
This product is comparable to the ATI Super Damper for the MX5, but operates over the full rev range of the engine and doesn’t require press fitting.
