• Multi-ring elastomer damping design absorbs crankshaft torsional vibration across a broad RPM range
• Precision-machined billet steel or aluminum construction for superior strength and balance
• Replaceable and re-tunable elastomer rings — no need to replace the entire unit
• Accurate timing marks machined directly into the damper for reliable ignition timing
• Direct OEM-replacement fitment with no modifications required
• Designed to withstand extreme heat, high RPM, and sustained wide-open-throttle use

ATI Performance Products has been a trusted name in harmonic damper technology for professional motorsports and high-performance street builds. The ATI916863 Super Damper is built to exacting tolerances and backed by ATI's reputation for quality, making it an ideal upgrade over factory rubber-bonded balancers that can fail under sustained performance driving conditions.
