Harmonic Balancer

The ATI 918522 Super Damper is an aluminum harmonic balancer specifically designed for the 1994-2005 Mazda Miata 1.8L engine, catering to both high horsepower street and race use. This damper functions as a direct replacement, effectively dampening torsional crankshaft vibrations across all RPM levels and safeguarding the engine against harmful harmonics. Constructed from aluminum with a black finish, this 5.5-inch diameter harmonic balancer features an internal balance type. The design aims to improve engine longevity and reliability under demanding conditions. While the JEGS listing states mounting hardware is not included, other sources indicate that hardware and a keyway may be included with certain versions of this part, such as the 918522BG. Buyers should verify the exact contents of the package.
