ATI Super Damper for Mazda MX-5 NA NB
The ATI Super Damper protects your engine by damping harmonic vibrations in the crankshaft. Without a proper damper, significant harm can be caused, from worn main bearings to oil pump failure. The ATI Super Damper utilises a series of O-rings and an inertia ring to dampen the vibrations and reduce torsional twist in the crank. This configuration allows the ATI damper to absorb harmonics over an extremely wide RPM range, often exceeding 9,000 rpm.
Standard dampers are a two-piece design, bonded together with an elastomer. The outer ring can work loose as the pulley ages or is subjected to extreme operating conditions. As the outer damper is balanced the end of the manufacturing process, any movement of the outer ring can unbalance the pulley and put extra stress on the crankshaft. Replacing the old damper with a rebuildable ATI Super Damper is recommended on high-horsepower builds.
