Ati

ATI's patented Super Damper technology allows for a true balanced crank pulley to avoid irregular runout and vibrations with your crankshaft. In high power builds, these vibrations can actually rob power or cause long term negative effects to the crankshaft itself. ATI's products are among the highest quality in the industry and cannot be compared to the traditional lightened or underdrive pulleys. We have specifically tested their products first-hand in many applications to be able to verify their claims.
