ATI Performance Products ATI916044 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916044 Super Damper is a high-performance crankshaft harmonic balancer engineered for demanding racing and performance street applications. ATI's Super Damper series is widely recognized as the industry standard in torsional vibration control, protecting crankshafts and rotating assemblies from the destructive harmonic forces generated under high-RPM and high-horsepower conditions.

Unlike stock OEM balancers that use a rubber bonding element prone to failure under heat and stress, the ATI Super Damper utilizes an inertia ring and precision O-ring dampening system that provides consistent, reliable vibration attenuation across a broad RPM range. This design is rebuildable and tuneable, making it a preferred choice for serious engine builders and racers.

Key Features:

• Precision-machined billet aluminum construction for reduced rotating weight
• O-ring dampening system — more consistent and durable than rubber-bonded OEM-style units
• Rebuildable and tuneable design for long-term serviceability
• Provides superior torsional vibration dampening to protect crankshaft and engine bearings
• SFI 18.1 certification (verify with ATI for this specific unit) for sanctioned racing use
• Laser-etched timing marks for precise ignition timing reference
• Direct-fit replacement — no modifications required for compatible applications

ATI Performance Products has been manufacturing performance drivetrain components since 1966, and their Super Damper line is trusted by professional racing teams across NASCAR, NHRA, road racing, and high-performance street builds. The ATI916044 delivers the durability and precision required for serious performance applications.
