ATI Performance Products ATI916215 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916215 Super Damper is a high-performance crankshaft harmonic balancer engineered to suppress torsional vibration and protect your engine's crankshaft, bearings, and valvetrain from damaging resonance. ATI Super Dampers are the gold standard in performance and racing damper technology, trusted by professional racers and serious enthusiasts worldwide.

Unlike factory rubber-bonded OEM balancers that degrade over time and lose damping effectiveness, ATI Super Dampers use an elastomer ring precisely tuned to your specific engine's torsional frequency. This design provides consistent, long-lasting vibration control under the extreme conditions of high-RPM performance use.

Key Features:

• Precision-machined billet aluminum construction for strength and weight reduction
• Elastomer-tuned torsional vibration dampening for superior crankshaft protection
• SFI 18.1 certified for sanctioned racing competition
• Laser-engraved degree markings for precise ignition timing
• Compatible with standard OEM-style front seal
• Reusable and rebuildable design — elastomer can be replaced without replacing the entire unit
• Manufactured in the USA by ATI Performance Products

ATI Super Dampers are a direct upgrade over OEM harmonic balancers for performance builds, offering measurable protection against crankshaft fatigue and engine component wear. Whether used on the street or the strip, the ATI916215 delivers the reliability and precision that ATI is known for.
