Description

The ATI Super Damper harmonic crankshaft pulley is designed for the B58 Supra GR. It is available in a stock replacement size or a 21% underdriven version. This pulley dampens torsional crankshaft vibrations across all RPM ranges and protects against engine harmonics. It features laser-etched timing marks and a black zinc chromate coating to prevent rust, while also exceeding SFI 18.1 Safety Certification for competition use.
