Product Description

The ATI ATI917381 Super Damper is a premium harmonic balancer engineered specifically for Toyota's G16E-GTS 1.6L turbocharged three-cylinder engine used in the GR Corolla, GR Yaris, and select Lexus Morizo RR applications. Designed as a direct replacement for the factory damper, it provides superior control of crankshaft torsional vibrations across the entire operating range.

Unlike conventional OEM dampers that are optimized for a narrow range of driving conditions, ATI's patented Super Damper technology delivers consistent vibration control during daily driving, aggressive street use, and motorsport competition. The lightweight aluminum shell, steel hub, and three-ring inertia assembly work together to reduce harmful harmonics that can negatively affect engine reliability and performance.

With OEM-sized dimensions, integrated 6-groove belt drive, laser-etched timing marks, and SFI 18.1 certification, the ATI917381 offers a direct-fit solution for enthusiasts seeking improved engine protection and long-term durability without sacrificing factory accessory compatibility.
