ATI Performance Products ATI917333 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI917333 Super Damper is a high-performance elastomer harmonic balancer/crankshaft damper engineered to reduce torsional vibration in high-output engine applications. Designed as a direct upgrade over stock dampers, ATI Super Dampers are a trusted choice among professional racers and performance enthusiasts who demand precision, durability, and power protection.

ATI Super Dampers use a precision-machined, SFI-certified billet aluminum shell combined with a specifically tuned elastomer ring to absorb and dissipate harmful crankshaft torsional vibrations. By controlling these vibrations, the damper helps protect crankshafts, bearings, and rotating assembly components from fatigue and failure under high RPM and high-load conditions.

Key Features:

• High-strength billet aluminum construction for reduced rotational mass
• Precision-tuned elastomer dampening ring for optimal vibration control
• SFI 18.1 specification compliant for sanctioned racing applications
• Precision laser-etched timing marks for accurate ignition timing
• Direct OEM-style fitment for straightforward installation
• Designed for high-RPM and high-horsepower engine builds
• Serviceable design — elastomer can be replaced to extend product life

ATI Performance Products has been manufacturing racing and performance drivetrain components in the USA since 1965. The ATI917333 Super Damper reflects their decades of engineering expertise, making it an ideal choice for circle track, drag racing, road racing, and street/strip performance applications where crankshaft protection and precision are non-negotiable.
